The Pteranodon family goes back underwater in the Dinosaur Train Submarine and meet Maisie and Marvin Mosasaurus, a daughter and father who are huge, fast-swimming lizards with flippers. Maisie and Shiny bond when they discover neither likes to go down deep in the water. The Pteranodons and Mosasaurus have a great time up near the ocean's surface, each family showing the other how they hunt and catch fish to eat. When Mrs. Pteranodon announces that she and Mr. Pteranodon are going on a special anniversary date that night, and the Pteranodon kids will have their first babysitter ever, the kids are not very happy. The babysitter is Keira Chirostenotes, a responsible, patient teenager. Buddy, Tiny, Shiny, and Don each take almost the whole evening to warm up to her. While Mom and Dad are on their date on the Dinosaur Night Train, Mom is relaxed, but Dad really misses the kids and can't stop thinking about them. In the end, Mom and Dad rush back to the nest to find all the kids and Keira having a great time!

Our Pteranodon family is on the beach watching small eggs hatch and baby Archelon turtles emerge, and start to swim away. Our family and Mr. Conductor get into the Dinosaur Train Submarine and follow the baby Archelons who discover their own facts of nature - that their mother doesn't stay with them after they're born, and that they will grow up to be giant-sized sea turtles. Tiny and Buddy find out that a newer train will be riding the same tracks as the Dinosaur Train. The new train is called the Rocket Train, and its conductor is named Thurston Troodon, who was a former classmate and rival of Mr. Conductor. Thurston is very confident and boasts that the Rocket Train is newer, better, and faster than the "old Dinosaur Train." Mrs. Troodon, Thurston, and Mr. Conductor's old teacher, suggests a friendly train race. With Tiny and Buddy on board, the "old" Dinosaur Train ends up helping out Thurston and the new Rocket Train after it breaks down.

"Crystal and King Benefit Concert: Part One" - When Crystal and the King go for a trip to the Big Pond, they learn that it's being recklessly overfished! They enlist the help of the Pteranodon Family to try to spread the word that if the dinosaurs and pterosaurs aren't more careful, the Big Pond will run out of fish to eat. But when Crystal realizes that nothing they're doing is actually raising awareness of the issue, she decides to organize a HUGE benefit concert, and everyone agrees to pitch in and help (as long as the King doesn't have to perform)! "Crystal and King Benefit Concert: Part Two" - The "Don't Overfish the Big Pond" Benefit Concert is underway, and it's a HUGE success! But because there's so much to organize, Crystal never finds the time to rehearse her big finale - so when it's time for her to go onstage, she experiences something she's never experienced before - stage fright! Can the kids help Crystal get over her stage fright and get her back onstage, or will the King have to come out of "performance retirement" to help her out? Educational Objectives: Overfishing generally results in a dramatic depletion in the total amount of fish (i.e., biomass). Also, overfishing often causes smaller fish (the prey species of larger fish) to increase in number as the larger predators are removed. If aquatic ecosystems are given a chance to rebound, they often will, as long as the numbers of fish have not been depleted too far.

The Pteranodon kids visit the Jurassic Time Period to meet Apollo Apatosaurus, a huge, long-necked, long-tailed dinosaur who likes adventure. Apollo loves to whip his long tail, and does so as he leads the kids on a pretend adventure to find a hard-to-reach tree with yummy, delicious leaves! Mrs. Pteranodon cleans out the clutter from the family nest and the kids are amazed at the pile of stuff - leaves, flower petals, pieces of wood, and shells. Tiny stops Mom from throwing out all the stuff, determined that she and Buddy, Tiny, and Don will find a use for it all. And, they do- the Pteranodon kids have fun making nature art on the beach using the items from nest!

Great Big Stomping Dinosaur Feet! - Tiny is very worried after she loses Shiny's favorite shiny shell, and enlists Dad and Buddy to help find a new one. As Tiny becomes more frantic, she begins stomping with frustration. Then the kids meet Daphne, a Daspletosaurus kid who shows them how to make stomping a fun dance instead of a temper tantrum. Hornucopia - Mr. and Mrs. Pteranodon decide to surprise each other with gifts on their anniversary. Despite some close calls, the kids help each of them to keep their gifts a secret until the perfect moment when the whole family can celebrate.

The Amazing Michelinoceras Brothers - The Pteranodon family travels deep underwater on the Dinosaur Train to view two backwards-bounding brothers named Max and Mitch Michelinoceras. The kids are delighted to see that Max and Mitch put on a synchronized swimming show. Dads' Day Out - Buddy, Tiny, and Mr. Pteranodon join Annie Tyrannosaurus and Leroy Lambeosaurus and their dads for a Dads' Day at the Big Pond. It's all fun and games until it starts to rain, and they all have to take cover in a cave they've never noticed before.

Tiny wakes up feeling a little sad. When asked why, she can't really explain it: "Sometimes I just feel sad." To cheer her up, Shiny decides to show her how much she loves her. It goes over so well it starts a love-sharing chain reaction, as one by the one the Pteranodon Family gets in the on the action! / After Tiny, Shiny, Buddy, and Don are feeling "over-burdened" by chores and requests for help with small things from Mom and Dad - basically the kids just want to play - a plan is hatched. Mom and Dad come up with a fun scavenger hunt in the nest area that cleverly has the kids doing their chores even as they play. The hunt includes simple riddles the kids have to solve. Mom and Dad have certain items to be hunted for that involve cleaning up an area first, etc. (Note: it's the beginning of Autumn, so some leaves are changing colors, others are falling.) A surprise last scavenger clue brings the family to the Dinosaur Train to consult with the Conductor and have a Dining Car dinner.

Carla Cretoxyrhina - On this underwater excursion, the Pteranodon family meets up with Carla Cretoxyrhina, a young shark who turns out to be much nicer than her reputation suggests. She introduces the family to her dad, bringing them face to face with the "Big Fish in the Sea." Train Trouble - The speedy dinosaur brothers Oren and Ollie join our kids on a train trip to Troodon Town, but unplanned engine trouble sends Oren and Ollie sprinting the Roundhouse to bring back another engine to save the day!

An Armored Tail Tale - The Pteranodons tag along as Hank Ankylosaurus visits the Big Pond to scout a Dinoball talent named Eugene Euoplocephalus. Eugene is a smaller version of Hank, an armored dinosaur with a giant tail-club. Hank and Eugene really hit it off, and after they all play Dinoball, Hank recruits Eugene to play on his team! Pterosaur Flying Club - Tiny and Shiny practice their swoop-de-loops and other flying moves in anticipation of their play-date with fellow Pterosaurs Petey Peteinosaurus and Quincy Quetzalcoatlus. With Buddy helping with the choreography, the Pterosaur Flying Club puts on a flying show!

Buddy and Don stumble upon a mystery when they find unhatched eggs on their beach, The mystery grows when some of the eggs are stolen. Don and Buddy become detectives and suspect that maybe Tiny, Shiny, or other friends may be stealing the eggs. They're not. Soon, all the kids join in to solve the mystery, as they figure out that the eggs belong to an over-protective, caring mom named Olivia Oviraptor who is just trying to keep her eggs safe. Buddy, Tiny, Shiny, and Don have fun spending a special day with their retired Grandma and Grandpa at their cliffside nest. The kids get to see things from their Dad's childhood nature collection, and afterwards they play games and fish with Grandma and Grandpa.

While Mikey Microraptor is visiting Tiny at the family nest, next-door neighbor Larry Lambeosaurus tells Mikey that he can't actually be a dinosaur, since he's so small, and all dinosaurs are gigantic. Tiny and Mikey decide to show Larry he's mistaken. They take the Dinosaur Train to find the tiniest dinosaur of all - in Jurassic China. There, they meet Yi qi, a new tiny dinosaur, the size of a pigeon, whose name means "strange wing" because its wings are made of skin! She's otherwise covered in feathers. Tiny and Mikey learn Yi qi's point of view: "Everyone thinks dinosaurs are huge. I'm small, but I'm still a dinosaur!" Mikey is thrilled to meet a dino smaller than himself. Then Mikey, Tiny, and Yi qi bond over being small but proud, and exclaim their rallying cry of "Tiny Power!" Yi qi joins this group of tiny dinosaurs. The Conductor is inspired to create a Tiny Dinosaur Train, especially adapted to accommodate tiny dinosaurs. Larry meets the tiniest dinosaur when the Tiny Dinosaur Train rolls into the station, is properly impressed, and the kids sing a new "Tiny Power!" song / Buddy and Tank Triceratops are best friends, and they share a love for comparing features. Tank, who has 3 horns, wonders why Mayor Kosmoceratops has 15, and Protoceratops has only 1. Buddy, Tank, and the other kids go on a quest to track down Ceratopsians with horns numbering from 1 to 15. In their travels, they end up meeting "the Queen," an amazing Late Cretaceous Regaliceratops, who has a very decorative frill that almost rivals Kosmoceratops for number of horns!

The Good Mom - "Mom's" the word when Mrs. Pteranodon meets fellow mom Millie Maiasaura, who is a little too over-protective of her kids. The two moms compare mothering methods in a play date at the Big Pond. Hornucopia! - At the Big Pond, Tank introduces the Pteranodon family to his friend, Stacie Styracosaurus, a fellow Ceratopsian with a crown of elaborate horns on her head. Everyone attends Stacie's "Hornucopia" celebration, where she reveals her new big horns and then performs a moonlit shadow show with her Styracosaurus family.

Dad takes the kids on a special Night Train to Troodon Town, where the Troodons have decorated their Roundhouse into a "haunted house" for a spooky party. The kids end up meeting a strange new nocturnal creature - a mammal named Vlad Volaticotherium, who was hiding in the roundhouse trying to get some sleep. The Pteranodon family learns more about the customs of their neighbors, the Lambeosaurus family, when they are invited for the first time to accompany them to the Big Pond to celebrate "Gourd Day" - a kind of Mesozoic Halloween. The kids see their first pumpkins, and Larry Lambeosaurus even shows our family how to hollow them out and carve faces into them.

The Pteranodon family sends Buddy on the Dinosaur Train so he can join Annie, Deloris, and Boris Tyrannosaurus for a week on their migration, traveling with the T. rex pack as they follow a herd of giant sauropods across the plains of Laramidia. As Buddy travels with Annie's family, he gets to experience being a T. rex more than he's ever done. During the migration, Buddy deals with several `firsts': being away from home alone for the first time, being with another family, being on the move every day, and being homesick. Buddy and Annie bond more as they make it through the week. By the end of the week, Buddy is more adapted and glad that he experienced T. rex life a little more than he's ever done before. But he's really happy to come back to his adopted family, and has a new appreciation for them. / When Mrs. Pteranodon overhears Buddy telling his siblings what a great time he had on migration, she gets the idea to create a Pretend Migration for the kids. Tiny, Shiny, Don, and Buddy must use their senses and follow the clues to their surprise dinner at the Big Pond!

For their second outing at Nature Trackers Adventure Camp, Buddy, Tiny, Shiny, Don and other friends learn about the tree line as they set out to hike up a mountain. Shiny is determined to get to the top of the mountain forest. Buddy wonders if they'll be able to see anything from the mountaintop through the tall trees. The kids are amazed that the higher they hike, the shorter the trees and bushes get! Then they reach the tree line--a certain point on the mountain where trees are really small because they don't have enough air to breathe and the temperature is too cold. In the end, Shiny and all the kids use teamwork to reach the mountaintop together!

Dad takes the kids on a special Night Train to Troodon Town, where the Troodons have decorated their Roundhouse into a "haunted house" for a spooky party.

"Spooky Tree" - Shiny invites Annie Tyrannosaurus to Pteranodon Terrace for a sleepover, but all Annie wants to do is investigate the "spooky tree" that Don says "comes alive at night." All Shiny wants to do is stay as far away from the tree as possible. Can the kids get to the bottom of the mysterious tree, and figure out if it really comes alive at night? Educational Objectives: A wide variety of organisms produce light inside their bodies, and this light can be used for a variety of purposes. Some creatures have a chemical reaction in their bodies called "bio-luminescence," which causes them to glow. This bioluminescence can serve different functions, including camouflage, luring of prey, mimicry of other animals, and warnings for potential predators that the glowing critter is unpalatable. "Spinosaurus Super Model" - When Don stumbles across a stick that looks EXACTLY like Old Spinosaurus, he's determined to have the grumpy old dinosaur pose for his sculpture (so he can get the Spinosaurus's features exactly right). But when they arrive at Old Spinosaurus's home, he makes it clear that there's no way he's posing for anything. Can Don convince Old Spinosaurus to pose for his sculpture, or will Don have to come up with another plan? Educational Objectives: Spinosaurus, a gigantic theropod from the Cretaceous period, was the world's largest land carnivore, and the only Mesozoic dinosaur truly built for living in the water versus on land (as opposed to going into the water to cool off, for example).

Tiny can't believe it when he finds out that his friend Cindy Cimolestes doesn't like fish, but she explains that she's a mammal and many mammals don't eat fish. Determined, Tiny sets out to find a mammal in the Mesozoic who likes fish, so she, Buddy, Cindy and Dad set out on a fishing trip where they run into Cassie Castrocauda, a Jurassic mammal that looks like a cross between a beaver, an otter and a platypus, who also happens to love fish! One morning at the family nest, Don befriends a butterfly that he names Dan. Don, Buddy, Tiny and Shiny watch Dan and three of his "sibling" butterflies fly around until suddenly they disappear, leaving Dan all alone. Don feels for the separated butterfly and vows to re-unite him with his siblings. After Mom and Dad give a quick lesson about butterfly camouflage, Don leads his own siblings all around the nest area searching for Dan the Butterfly's lost "sisters and brother." The whole time, Don keeps an eye on Dan, who camouflages himself when any threat (birds or a frog) are nearby. The long search doesn't yield the missing butterflies. Then, at the end of the day, our family is amazed when Dan's family reveals that it had been camouflaged in a flower headband!

Elmer Elasmosaurus - The Pteranodon family travels on the Dinosaur Train with the Aquacar to an underwater train station to transport Elmer Elasmosaurus back to his home in the ocean. At first Buddy is not enthusiastic about travelling underwater, but quickly becomes a convert when he sees the spectacular sights under the sea. Dinosaur Block Party - The Pteranodon family hosts a block party to introduce their new neighbors, the Lambeosaurus family, to all the other neighborhood creatures. The different species all join together to fly, dive, fish, race and especially, to rock the block!

Dad takes the kids on a special Night Train to Troodon Town, where the Troodons have decorated their Roundhouse into a "haunted house" for a spooky party. The kids end up meeting a strange new nocturnal creature - a mammal named Vlad Volaticotherium, who was hiding in the roundhouse trying to get some sleep.

After Buddy, Tiny, Shiny and Don learn that it's Mr. Conductor's birthday, they decide to throw him a surprise party in his favorite place - the Dinosaur Train! The whole family plans the party, secretly riding the Rocket Train to pick up friends from all around the Mesozoic and gather ginkgo leaves for a special birthday cake. The party is a huge success - the Conductor is surprised and moved, and loves his tasty ginkgo leaf birthday cake. As the Pteranodon kids play in their family nest, Buddy stares at a sky full of clouds and asks the group, "What are clouds?" Mr. Pteranodon and his neighbor, Mr. Lambeosaurus, have different opinions. As they all get on the Dinosaur Train, they consider whether clouds are made of water or whether they're just made of fluff. Tiny knows who would have the facts--Mr. Conductor! He explains that clouds are made of billions of tiny drops of water that are so light they float in the air. He also takes the group to Cloudy Point Station where the kids play a cloud-spotting game, identifying the three types of clouds they learned about: cirrus, stratus, and cumulus. In the end, a rainstorm certainly proves that clouds are made of water!

It's time for the "Classic in the Jurassic" - the Mesozoic Olympics! Today's "Air, Water and Land" contest is a three-part competition pitting teams consisting of a pterosaur and a crocodile from each Time Period against one another. Mrs. Pteranodon, Tiny and Shiny are recruited to help in one of the three "legs" of the race, while Buddy, Don and Dad watch from the stands. The competition's three "legs" are flying, swimming and a lap around a track. Early on, Team Cretaceous pulls ahead and hold onto its lead, until the wild card of the race is revealed: Team Triassic's croc, Effie Effegia, who shocks the crowd when she runs, and then sprints, on two legs! Effie wins the race, and her bi-pedal ability prompts many questions - and a healthy discussion -- about her features. Tiny is disappointed her team lost, but cheers up when reminded that she was part of `"Classic in the Jurassic" history. While playing "Cold and Hot," a game they made up, the Pteranodon kids learn from Mr. Pteranodon that there might be more variety in the desert than they imagined. Their curiosity piqued, they plead for a trip to investigate the desert scene. Mr. Conductor tells them just how diverse plant and animal life can be in the desert. He happens to know a desert mammal: Fruitafossor. Upon disembarking from the Dinosaur Train, the Pteranodon kids meet Frankie Fruitafossor, a chipmunk-sized mammal. They quickly learn that their assumption that desert life was hot all the time and relatively uninhabited was incorrect. Come dusk, they find the desert hopping and crawling with life, as creatures emerge all over - mostly underground - where they hide from the blazing sun. Frankie gives our family a tour, including a peek at underground burrows he dug. Back on the desert floor, Don and the siblings can't believe how cold the desert has become. Nighttime in the desert is a different world than daytime! The family goes back to the Dinosaur Train to warm up and have a snack.

Paulie Pliosaurus - The Pteranodon family takes the Dinosaur Train underwater to visit a marine reptile called Paulie Pliosaurus, a creature known as the "T. rex of the Ocean." Buddy and Paulie compare features and find that they actually have a lot in common. Elmer Visits the Desert - Our Pteranodon family takes their ocean friend Elmer Elasmosaurus on the Dinosaur Train to a place he's never been before: the desert! Once there, the kids compare the sandy terrain to Elmer's ocean, and they meet a local lizard named Percy who tells the tale of his desert home.

Our Pteranodon family accompanies Mr. Conductor to the Troodon Town Roundhouse to meet up with Thurston Troodon, the Rocket Train's conductor. They all soon learn that Tricia Troodon, a young hotshot conductor, actually invited everyone there to see her new train - the Solar Train! The kids learn that it's powered by the sun! To test the train's performance, the three Conductors, along with the help of Buddy, Tiny, Shiny and Don, race the Dinosaur Train, Thurston's Rocket Train and Tricia's new Solar Train to the Triassic! Buddy and Tiny give Elliot Enantiornithine, a first timer on the Dinosaur Train, a tour of the Train. When they go through Laura Giganotosaurus' car, she explains to them that today is her bird watching/drawing day, but she hasn't found a single bird to watch. But, there's Elliot. He hams it up for Laura, who watches and draws him. This is so fun that Buddy and Tiny bring Laura to meet another bird friend-- Arlene Archeopteryx. Then Arlene and Elliot introduce the kids and Laura to a new bird named Peng Protopteryx! It's a successful birdwatching/drawing day as all three birds are delighted to show off their unique feathers.

Junior Conductor Jamboree - Our kids ride the Dinosaur Train from one end of the line to the other, through all three Time Periods -- from the Cretaceous, through the Jurassic, to the Triassic. All along the way, they pick up friends who join them for a Junior Conductor Jamboree! Troodon Train Day - The Pteranodon family rides to Troodon Town to celebrate Troodon Train Day, where the main event is a concert by King Cryolophosaurus, giving his first performance in years! When King comes down with some last-minute jitters, Buddy and Tiny help him overcome his stage fright and he sings a medley of his hits, including the Dinosaur Train theme song!

"Spooky Tree" - Shiny invites Annie Tyrannosaurus to Pteranodon Terrace for a sleepover, but all Annie wants to do is investigate the "spooky tree" that Don says "comes alive at night." All Shiny wants to do is stay as far away from the tree as possible. Can the kids get to the bottom of the mysterious tree, and figure out if it really comes alive at night?

The "Classic in the Jurassic" games are back, and this time, it's the Ultimate Smackdown. Mr. Conductor explains the "wrestling" matchups from the three Time Periods are: T. Rex vs. Triceratops, Allosaurus vs. Stegosaurus and Zupaysaurus vs. Riojasaurus (dinos new to the Pteranodon clan.) Fears that competitors may get injured are allayed by the explanation of how the "Smackdown" works -- the best choreographed and most entertaining show wins! Morris Stegosaurus beats Alvin Allosaurus. When Ziggy Zupaysaurus goes up against Renaldo Riojasaurus, Mr. Conductor explains that Riojasaurus may be smaller, but he has a powerful tail and speed on his side. Then Boris the T. Rex loses to Trevor Triceratops. Tank and Buddy are thrilled-what a face-off! Once the judges tally the results, Team Cretaceous is declared the winner, and the fans love it! Buddy and Tiny wonder aloud whether the Triassic was the beginning of time, and if there was anything before the Age of Dinosaurs. So, to the Dinosaur Train they go where Mr. Conductor takes them back to the beginning of the Triassic Period to get some answers. In the Triassic, Buddy, Tiny, Mom and Mr. Conductor meet up with Erma Eoraptor who is happy to explore the "before the Triassic" question with them. Our group walks through a Pedestrian Time Tunnel (that's beyond the end of the train tracks) to get to the Permian Period, the time period immediately before the Triassic. There, they meet Deon Dimetrodon, who has never met a dinosaur or pterosaur before. Buddy and Tiny are amazed to learn that there are neither of these in the Permian Period (or earlier)! Deon marvels at our family's features - especially Tiny and Mrs. Pteranodon's wings. Deon shows our group around the hot and humid Permian, and he explains how his sail fin keeps him cool. Then Deon is delighted to experience the Mesozioc Era. He walks through the Pedestrian Time Tunnel with our group, and is blown away by the vegetation and the variety and size of dinosaurs. Another lifelong friendship is forged!

The Pteranodon family is super excited to be traveling to the "Classic in the Jurassic," an Olympic-type competition in which different dinosaur teams representing the three Mesozoic time periods will compete in various contests. Today's competition is a race between turtle and theropod teams. When the fast-running theropods all get tangled up at the finish line, the race comes down to the slow-moving turtles. It's an exciting race as the turtles are neck and neck! Who will win this pre-historic match up?? Buddy, Tiny and Mrs. Pteranodon are eating lunch at Pteranodon Terrace, and even though they've just eaten a big fish meal, Buddy's tummy is still grumbly-hungry. Mom understands that because Buddy is a carnivore he needs meat, so she takes the kids to the Dining Car on the Dinosaur Train to get him some carrion. While dining, Laura Giganotosaurus tells Buddy that the best meal she ever ate was prepared by her cousin, Chef Carson Carcharodontosaurus. So Buddy, Tiny, Mom and Laura all travel to meet the boisterous and generous Chef C and eat some of his famous carrion dishes. Buddy's tummy is happily full when our family leaves to head home. They even bring back a snack for Mr. Conductor!

Dad takes the kids on a special Night Train to Troodon Town, where the Troodons have decorated their Roundhouse into a "haunted house" for a spooky party. The kids end up meeting a strange new nocturnal creature - a mammal named Vlad Volaticotherium, who was hiding in the roundhouse trying to get some sleep. The Pteranodon family learns more about the customs of their neighbors, the Lambeosaurus family, when they are invited for the first time to accompany them to the Big Pond to celebrate "Gourd Day" - a kind of Mesozoic Halloween. The kids see their first pumpkins, and Larry Lambeosaurus even shows our family how to hollow them out and carve faces into them.

When the Pteranodon kids decide to draw some maps, Don's map of one big land mass for "the whole Mesozoic" triggers a discussion on whether the Mesozoic is "one big place that's all connected" or comprised of a bunch of smaller, interconnected land masses. On the Dinosaur Train, the Conductor explains that millions of years ago there actually was just one big land mass called "Pangaea"! Then, over a long period of time, it started to drift apart and form separate, smaller landmasses, or continents. Our family can't believe it! The Conductor offers to take the Pteranodons up in the Zeppelin and through a Sky Time Tunnel, back to the time of Pangaea. At the Zeppelin Station, they meet up with Tricia Troodon, who helps pilot the Zeppelin on their journey. Once in the sky and through the time tunnel, our family is able to see Pangaea, the one giant landmass, just as it's starting to break apart. Then the family travels forward in time and views the continents separating more as oceans and seas move in between the land. Looking down at how their coastline looks in the Cretaceous Period, Buddy, Tiny, Shiny and Don all agree that seeing Pangaea breaking apart is one of the coolest things they've ever seen! As the Pteranodon kids are playing outside their nest, a few seedpods fall from a nearby tree, bonking Don on the head. This leads to a discussion about how far away things can fall from...maybe even from space?? Buddy hypothesizes that perhaps if a star came close enough, it could land on Earth! On the Dinosaur Train, the Conductor explains that things actually do fall from space. Big space rocks, called "asteroids," sometimes land on Earth, and when they occasionally do, they make a biiiiig hole, called a crater. Don perks up at this-he'd love to see a crater! So the Conductor takes the Pteranodon Family up in the Zeppelin to see a giant crater from above! On the ground, they explore the crater and find fragments of "space rocks" from the former asteroid. As evening falls and our family flies back home, the Conductor and Mom and Dad surprise the kids with a picnic dinner on the Zeppelin-hurrah!

The kids visit the Big Pond to attend the Biome Block Party. While attempting to win the leaf-necklace contest, Keenan Chirostemotes claims the Pteranodon sibs can't compete for the prize for "dinosaur" with the most leaves because they are not dinosaurs. This launches the kids into a song called "That's Not a Dinosaur", as all the non-dinosaurs sing their piece. In the end, the game rules are changed to include all creatures, even non-dinosaurs, in all the contests! The Nature Trackers go on a visit to the Big Pond, where Tiny hopes to see her favorite flowers. The Conductor tells her that if the kids gather seeds at the pond, they can bring them home and plant a garden full of those same flowers at the family nest! The kids all get into it, gathering seeds and bringing them home, where they plant a garden, and meet its new inhabitants, including Sammy, a friendly slug, who explains that slugs, spiders, and butterflies all help to make a garden complete.

The Pteranodon family rides a special 'Night Train" to another part of the Cretaceous Time Period, where they meet a Troodontid "cousin" of the Conductor's, Sidney Sinovenator, who knows more about the stars than anyone. Sidney takes the family up to his favorite stargazing spot, "Starry Hill," and teaches the kids why the stars seem to move across the night sky. When the kids build their own version of a nest on the beach, below their actual family nest up on the cliff, they get the idea to turn their beach nest into a clubhouse. Shiny thinks that a clubhouse needs a club, and "the Nature Trackers" club is born! The kids decide to make their club about getting outside, getting into nature, and making new discoveries. The only problem is: which kid is in charge of the club?

The Conductor's nephew Gilbert has been taking Conductor courses at the Troodon Academy, and has finally graduated to Cadet Conductor! The kids are thrilled - will Gilbert get his own Dinosaur Train to conduct? The answer comes when the Conductor gets sick and can't do his job, including calling out the station stops! He appoints new Cadet Gilbert to run the Dinosaur Train until he gets his voice back. The strain of running the train by himself wears heavily on Gilbert, and our kids step in to help him run it. Gilbert learns it takes a team to get the job done and keep the train running. There's big relief when the real Conductor gets his voice back and goes back to running things. No one's more relieved than Gilbert! / Our kids want their own clubhouse, separate from the family nest. They try out several locations - Tiny's Tiny Place, Dad's Thinking Tree, a large Don-made hole - but none of them are the right fit. Eventually, the kids (with the help of Mom and Dad), build their own clubhouse using natural materials.

The kids visit the Big Pond to attend the Biome Block Party. While attempting to win the leaf-necklace contest, Keenan Chirostemotes claims the Pteranodon sibs can't compete for the prize for "dinosaur" with the most leaves because they are not dinosaurs. This launches the kids into a song called "That's Not a Dinosaur", as all the non-dinosaurs sing their piece. In the end, the game rules are changed to include all creatures, even non-dinosaurs, in all the contests! The Nature Trackers go on a visit to the Big Pond, where Tiny hopes to see her favorite flowers.

Shiny gets over her fear of snakes when Tiny challenges the Nature Trackers to meet the ultimate snake: the Sanajeh, a huge Cretaceous snake from what is now India. Dad takes the kids on the Dinosaur Train to find Sana Sanajeh, who may be huge, but turns out to be quite friendly. Once Shiny and Sana become friends, Shiny returns home with the knowledge that snakes aren't scary - they're just another part of nature! Tiny is horrified when her favorite buttercups all wilt, so Mom takes her and the family to the Big Pond, where she remembers seeing a whole lot of buttercups in bloom. On the way there, the Conductor gives the kids a visual lesson in "Nature's Life Cycle," explaining how a flower grows, blossoms, then wilts, and returns its seeds to the ground, to start the cycle all over again. Tiny finds her flowers at the Big Pond, both blooming and wilting, and can see nature's life cycle in action.

Mom takes the kids on a playdate with Tank Triceratops to the desert, where they meet a distant relative of Tank's, an early Ceratopsian named Penelope Protoceratops.

The Conductor and the kids are out digging in a favorite fossil spot, out past the Big Pond. Buddy turns up something that the Conductor doesn't recognize. It's an excellent fossil - he guesses that they may have discovered a whole new Jurassic species! They all carefully finish digging out the beautifully intact theropod raptor skeleton and bring it to Troodon Town, where they can examine it at the Science labs at Troodon Academy. The experts agree: The Conductor and the kids have discovered a new Jurassic dinosaur! They nickname it "Buddysaurus." Now the Conductor must give a presentation to all the assembled Academy about this new Dracoraptor discovery. Used to being the authority and a kind of hilarious know-it-all, the Conductor is for once super-nervous and tongue-tied. The kids help him figure out how to properly and scientifically present his information and get over his nerves. Buddy leads them, and the kids even improvise a song about the new discovery, "A Brand-New Species!" It's a hit! / Buddy gets the idea to travel to the Early Jurassic and meet an example of their new discovery, a theropod they named "Buddysaurus." Unfortunately, since this is a brand-new-discovery, there is no train to the home of the Buddysaurus, nor a train station! The Conductor decides to take them all to the Early Jurassic, and hike from the nearest station to find this new theropod. And, they do! They discover that the theropod is actually called a "Dracoraptor." Our kids invite him to come back to Troodon Town with them so they can present him to the Troodon Scientists.

Buddy, an adopted T. rex, wishes he knew more about his T. rex ancestors. So, Dad takes him and Tiny on the Dinosaur Train back to the early Cretaceous, to visit an ancestor: an earlier version of Tyrannosaurus rex called Raptorex. Rodney Raptorex is a kid who won't grow up to be as big as Buddy will, but the two boys find that they not only have a lot of differences, they have a lot in common, too. The kids are stuck cooped up in the nest for a long, rainy spell which leads to them fighting. Mom tells them that the rain has stopped enough that they can leave the nest but she gives them an assignment: to go find their own "calm space," where they can calm down enough to get along with each other again. It works - each kid finds something in nature that helps him or her to calm down and be friends again.
