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!

The Nature Trackers Adventure Campers are back for another adventure and this time they'll be travelling to a rainforest! Once they arrive in the dense, overgrown rainforest, the campers explore different levels of the ecosystem, including the forest floor and the canopy of leaves at the top of the forest. After a hike through the rainforest, the campers' fun adventure culminates as each kid takes a ride on a zip line, where they all get a bird's eye view of the entire rainforest! The Nature Trackers Adventure Campers are led by Mr. Conductor and Gilbert on a hike down a canyon where they can see the different layers of the Mesozoic Era! At first Lily Lambeosaurus is reluctant to go, thinking that a new adventure sounds hard, but Don convinces her that a new adventure can be worth the effort. At the bottom of the canyon, the kids play Dinoball and then dig for fossils. Each Nature Tracker goes home with an Ammonite fossil, and Lily is so glad she tried something new!

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.

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!

King and Crystal Cryolophosaurus are back together in their on-again, off-again rock'n'roll relationship. The Conductor shows up to extend an offer to play the Red Rock Ampitheater in Laramidia (the Cretaceous mini-continent that is now the Rocky Mountains). Our Pteranodon Family is visiting King and Crystal in Jurassic Antarctica when they get the big news. Crystal is all for it - this concert is the big time! But King is hesitant, worried about performing because of stage fright. It takes emotional support from the Pteranodon kids to get King to perform, plus they help him get Crystal an anniversary gift. In the end, King and Crystal rock the Red Rocks and the festival crowd with their new hit song, "Red Rockin' the Cretaceous." / When Dad's good friend from their teenage years -- a pterosaur called Nyctosaurus -- comes for a long overdue visit, he's fun at first. Being a professional flyer, Nick thinks about flying 24/7, and teaches the kids exciting new flying and diving techniques for a couple of days. The kids need a break and end up showing Nick what they like to play - other activities besides flying. Nick appreciates that and invites the family to his upcoming big flying race!

"What's at the Center of the Earth? Layers!" -- The Conductor takes the Pteranodon family on a very special journey on a new invention - the Drill Engine Train - in search of the perfect spot for a new Underground Dinosaur Train Station! Don is THRILLED to be venturing into the BIGGEST HOLE THE EARTH HAS EVER KNOWN! Shiny is nervous to be underground, until they meet a new friend (a Mesozoic Mole named NATASHA NECROLESTES), who teaches them all about the different layers of the Earth. Story A Educational Objectives: The Earth has several layers - the crust (a thin, solid outermost layer), the mantle (the deeper, denser layer), and the core (the super dense center that's as hot as the sun). Also, a Necrolestes is a type of Mesozoic mole. "What's at the Center of the Earth? Fossils!" -- As the Pteranodon Family continues their journey underground, Don accidentally breaks Buddy's trilobite fossil (the oldest fossil in his collection!) When the search for another trilobite fossil turns up empty, their new friend Natasha Necrolestes takes them to Fossil Alley, where the kids learn that the older the fossil, the deeper underground it is. Story B Educational Objectives: You don't usually find fossils from different time periods mixed together in the Earth. The Law of Superposition means that when we see a stack of rock layers, the deeper you go into the Earth, the older the rocks and fossils you find

"Stop and Smell the Flowers" - Mom takes Tiny, Buddy, and Don on a super secret daytrip to Qianzhousaurus Pond, where they meet Quentin Qianzhousaurus - a Tyrannosaur with similar features to Buddy, except for one major thing - Quentin has a long, thin snout covered in tiny horns! The kids think that Quentin's long snout gives him a super smelling sense, but after a series of tests, they realize that he and Buddy have the same sniffing power. Can Quentin and Buddy's super sniffers solve the mystery of Mom's secret daytrip? Educational Objectives: Qianzhousaurus was a Tyrannosaur from the late cretaceous with a long, narrow snout (covered in tiny horns). Tyrannosaurs came in a variety of shapes and sizes. Qianzhousaurus probably hunted much smaller prey than its super strong- jawed cousin. T. Rex. "Moms' Campout" - Mrs. Pteranodon organizes a "Moms' Campout" with other moms and kids in the neighborhood. While on the way to the campout, Mr. Conductor challenges the kids to make a real "nature connection" by creating games that push them to look at nature from a different point of view. Educational Objectives: You can't appreciate nature just by looking at it. You need to dig in and be a part of it: splashing, climbing, getting dirty, and looking at things in a whole new way. Forming a "Nature Connection" (that is, fostering a bond with the natural world) is a hands-on, full body, multisensory activity that is essential for a healthy childhood.

When Mr. Pteranodon and Larry go out to the Big Pond to find some red platanoids for the Winter Solstice Celebration, they accidentally miss the last train home. Will Larry and Mr. Pteranodon stop bickering long enough to figure out a way home, or will they get stranded in the middle of nowhere and miss the family Winter Solstice Celebration? Educational Objective: The Winter Solstice is the shortest day of the year.

"Where Have All the Lizards Gone?" - The Conductor takes the Pteranodon Family for a special trip to Lizard Island, where they discover that it's been overrun by plants and bugs, and there are few precious lizards left. The Conductor concludes that the Changyuraptor Family (that he dropped off there awhile ago, and has since multiplied) has been eating all the lizards and throwing the entire ecosystem out of balance. Can the Pteranodon Family and Mr. Conductor convince the Changyuraptor Family to leave their home in order to get the island ecosystem back in balance? Educational Objectives: Ecosystems thrive only when all the plants and animals are in balance with one another. But too much of one thing, and not enough of another, can have disastrous consequences. "Conductor's Sleepover" - With a hurricane looming, the Pteranodon Family convinces the Conductor to leave his train for the night and come with them to the safety of their hurricane shelter (a large, underground cave). But the Conductor has a hard time getting comfortable away from his train. Can the family and the Conductor pull together and help a family of beached Ichthyosaurs back into the ocean after the hurricane leaves them beached on the shore? Educational Objectives: Hurricanes (and other storms) often have major effects on both ocean and land animals, causing animals to change their behaviors, and sometimes resulting in devastation of coastal ecosystems.

"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.

"Junior Conductors Academy: Part One" - The kids are all excited! Why? Because they're off to Junior Conductor's Academy in Laramidia, to try to become Junior Conductors First Class. Buddy has a feeling he's going to be a star in class, until he meets Dennis Deinocheirus - a kid who knows even more dinosaur facts than he does! Can Buddy get over his disappointment that he's not the smartest kid in class, and make friends with Dennis (who seems like he's having trouble making friends on his own)? "Junior Conductors Academy: Part Two" - Now that Buddy and Dennis are friends, they have to work together (with the other kids) in order to pass a series of tests. If they succeed, they'll receive their Junior Conductors First Class pins! But standing in the way of their success is the most challenging instructor of all... Thurston Troodon! Educational Objectives -- Deinocheirus, from the Ornithomimosaur family of theropods in the late cretaceous, had some of the longest arms of any bipedal dinosaur. Also, it's not always easy to make friends with someone you don't understand, but if you take the time and make the effort, it might not be as hard as you think.

While riding the Dinosaur Train with Buddy and Mom, Tiny gets the idea to gather all the dinosaurs in the `Dinosaurs A to Z' song for a picnic at Troodon Town. The Conductor agrees, and the Train starts picking up dinosaurs, as Tiny and Buddy help keep track of how many of the different species have come on board, and where they are on the dinosaur A to Z list. The Dinosaur Train continues traveling around the Mesozoic picking up more and more dinosaurs that are in the `Dinosaurs A to Z' song, on the way to a picnic at Troodon Town. As more train cars are added, and the rest of the Pteranodon family comes on board, Tiny and Mrs. Conductor team up to help keep order on the increasingly crowded Train.

"Rollin' on the Riverboat: Part One" - The whole Pteranodon Family takes a rollicking adventure on the Dinosaur Train Riverboat! Buddy and Don vow to spend every minute together, but while Buddy wants to spend all his time investigating the creatures on the river, Don wants to spend all his time playing games and investigating the buffet. Can they come to some kind of agreement? "Rollin' on the Riverboat: Part Two" - While still rolling down the river on the Dinosaur Train Riverboat, Grandpa Pteranodon tells Buddy about the Legend of Admiral Globidens - a HUGE Mososaur that supposedly lives on the river, but no one has ever seen. Buddy enlists Dad and Tiny's help to look for Admiral Globidens, but they can't seem to find him. Does Admiral Globidens really exist, or is he just a figment of someone's imagination? Educational Objectives: River ecosystems tend to be lushly vegetated and full of diverse life forms because of the constant presence of water and the diversity of habitats (i.e., aquatic and land-based). Also, a Globidens was a large mososaur from the late cretaceous that lived in the water and used its large, globe-shaped teeth to eat turtles and other large shellfish.

The Pteranodon family rides the Dinosaur Train - now with extra cars attached -- as it continues picking up more dinosaurs that are in the `Dinosaurs A to Z' song. The Pteranodon family reunites with some dinosaurs they've met before, and are introduced to species they've never met! The Pteranodon kids also learn about classification, and Don leads the way organizing the dinosaurs on the Train by their species, features, and size. The Pteranodon family is on the Dinosaur Train, now very crowded with all 26 dinosaurs mentioned in the `Dinosaurs A to Z' song. The Train has added more extra cars than it ever has, and there's even an additional engine to help pull the Train to Troodon Town. At Troodon Town, all the dinosaurs have fun at a picnic, and then Tiny leads the 26 different `A to Z' dinosaurs in a fun, rousing, and historic singing of the `Dinosaurs A to Z' song!

"What's at the Center of the Earth? Troglobites!" - The Drill Engine Train burrows into an underground limestone cave, where the Pteranodon Family meets some strange creatures without eyes called "troglobites." In a contest to see who would make the best troglobite, Buddy, Tiny, Shiny, and Don participate in a treasure hunt - with their eyes closed! The kids have to rely on their other senses (with some guidance from the actual troglobites) to navigate the cave and find the prize. Story A Educational Objectives: A speleologist is someone who studies caves. Also, there are creatures called troglobites whose bodies are specially adapted for living in deep caves without any light. "What's at the Center of the Earth? Minerals!" - While digging even further underground, the drill bit on the Drill Engine Train breaks. The Pteranodon Family find themselves in the Cave of Giant Crystals, where they learn all about rocks and crystals (what they are, how they're different, how they form). In order to get back home, the Pteranodon Family has to fix the drill bit by finding a mineral harder than the mineral that broke the bit in the first place. Story B Educational Objectives: Minerals form naturally in the Earth and are made of the same thing all the way through, while rocks are made up of a bunch of different kinds of minerals. Minerals come in thousands of different types (more than 4000 to be more exact), many of which form large and beautiful crystals, some of which are harder than others.

When the Pteranodon Family visits Troodon Town for a big Father's Day celebration, the Conductor sees Mr. Pteranodon enjoying being celebrated, and is compelled to ask his mother whatever happened to his father. She decides that he's ready to learn the truth and tells him the story about how his father was the bravest Conductor of them all and dared to build an experimental Drill Train and tunnel into the future -- she believes to the Cenozoic Era, which no dinosaur had ever seen. Unfortunately, the Conductor's father never returned, and is apparently lost. The Conductor decides to take the new Drill Train and tunnel into the future to rescue his missing father! / The Conductor, determined to find his missing father, takes the experimental Drill Train and drills a new Time Tunnel that goes as far into the end of the Mesozoic Era as possible, to drill farther into the future and find his father, Trevor Troodon. Once Dad and Buddy and Tiny get wind of this plan, they come aboard, too. So they all take the Drill Train and drill into the future. They come out in the Ice Age of the Cenozoic Era, where they meet a huge, furry Mastodon named Maurice. Maurice helps them search through the icy wastes until they find a feather-covered Northern Troodon who turns out to indeed be Trevor, the father of Mr. Conductor! A happy reunion for all, and they bring him home to the Age of Dinosaurs.

"Nest Swap" - The Pteranodon Family decides to take a little vacation and swap nests with Larry's friends: a family of pterosaurs (Nemicolopterus, to be exact). But when the Pteranodon Family arrives at the Nemicolopterus nest, they realize that the Nemicolopterus Family is MUCH smaller than them, so everything is smaller: the Pteranodon Family doesn't even fit in their nest! Can the family make do, try something new, and still have a good time? Educational Objectives: The Nemicolopterous was a small, toothless pterosaur that lived in the forests of the early cretaceous. Pterosaur diversity included a range in body size, head and body shape, presence and absence of teeth, long tails, preferred habitat, and preferred diet. "The Herd is the Word" - Tank Triceratops is really excited to show Buddy, Tiny, Shiny, and Don his favorite picnic spot, but when they arrive, the spot is overrun with a whole herd of Triceratops. Tank and the kids try to find another place with a little more privacy (and a lot less Triceratopses), but no matter where they go, the herd follows them. Will Tank be able to find a quiet spot without the herd, or does the herd have a good reason for following Tank around? Educational Objectives: Big-bodied herbivores often form large groups, or "herds," and do so as a strategy to detect and deter predators.

The Pteranodon kids have a Nature Trackers adventure when they meet Denise Diplodocus, a super-long, super big dinosaur. At first the kids mistake Denise's neck for a snake, and tail as a bridge. Later, Denise amazes the kids, telling them how hard it is for her to raise up her long, heavy neck. Shiny and the others help her raise her neck higher than normal just once, but it feels better for Denise to keep closer to the ground and low-lying trees. Shiny is nervous about Gilbert's impending visit to Pteranodon Terrace. She goes into a cleaning frenzy, wanting everything to look perfect, and her siblings to act perfectly. When Gilbert arrives, everyone starts having fun except Shiny who feels ignored. Soon Gilbert and the other kids persuade Shiny to join them, and they all eat, play, and laugh together.

"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).

Pteranodon Family World Tour - The entire Pteranodon family embarks on a roaring, exploring, World Tour adventure! They meet the Conductor's nephew, Gilbert, who takes them on a tour to meet Martin Amargasaurus, a spine spangled quadruped with an intimidating sail. Gilbert the Junior Conductor - The Pteranodon family is on a World Tour and get to sleep in a special Sleeping Car on the Dinosaur Train. During their first full day on the Train, the kids are super excited to play with Gilbert, the Conductor's nephew. Don gets jealous and finally admit his feelings, leading to a reaffirmation of his friendship with Buddy.

"What's at the Center of the Earth? Layers!" -- The Conductor takes the Pteranodon family on a very special journey on a new invention - the Drill Engine Train - in search of the perfect spot for a new Underground Dinosaur Train Station! Don is THRILLED to be venturing into the BIGGEST HOLE THE EARTH HAS EVER KNOWN! Shiny is nervous to be underground, until they meet a new friend (a Mesozoic Mole named NATASHA NECROLESTES), who teaches them all about the different layers of the Earth. Story A Educational Objectives: The Earth has several layers - the crust (a thin, solid outermost layer), the mantle (the deeper, denser layer), and the core (the super dense center that's as hot as the sun). Also, a Necrolestes is a type of Mesozoic mole. "What's at the Center of the Earth? Fossils!" -- As the Pteranodon Family continues their journey underground, Don accidentally breaks Buddy's trilobite fossil (the oldest fossil in his collection!) When the search for another trilobite fossil turns up empty, their new friend Natasha Necrolestes takes them to Fossil Alley, where the kids learn that the older the fossil, the deeper underground it is. Story B Educational Objectives: You don't usually find fossils from different time periods mixed together in the Earth. The Law of Superposition means that when we see a stack of rock layers, the deeper you go into the Earth, the older the rocks and fossils you find

Buddy, Tiny, and Mom visit their very large sauropod friend, Arnie Argentinosaurus, and his dad. Arnie has grown bigger since our kids have seen him and is now too big to ride on the Dinosaur Train anymore. Tiny and Buddy arrange with Mr. Conductor for Arnie to be the first big dinosaur to ride on the newest Dinosaur Train car - the flatbed car! Mr. Pteranodon and Mr. Lambeosaurus take all the kids to see a field of geysers - holes in the ground that hot water shoots out from! At the same time, Mrs. Pteranodon and Mrs. Lambeosaurus are relaxing nearby in soothing pools of warm water, called hot springs. In the end, the kids love seeing the geysers and then joining the Moms in their hot springs, while accidentally surprising Mr. Conductor who is secretly trying to relax in his own private hot spring pool!

The Old Bird - Buddy, Tiny and Mom make a play date with Petey Peteinosaurus to ride the Dinosaur Train to meet Arlene Archeopteryx, a bird from the family of the oldest birds ever! The kids are excited to learn that Arlene is a bird and a dinosaur.

An adventure into a local caves leads to a marvelous and brilliant discovery.

Team Pteranodon travels to Dienosuchas Swamp to meet Deanna Dienosuchas, a 40 foot crocodile with many big teeth, and a crabby attitude.

The kids delight in realizing they share similar traits with their grandparents (laughs, expressions, and interests), and love showing Grandma and Grandpa around the nest area and playing some games they all like.

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.

The Pteranodon family goes under the sea again, to ride the Dinosaur Train Submarine - this time they go to meet Shoshana Shonisaurus, an enormous marine reptile that's something between a dolphin and a whale. Since Shoshana loves to dive down very deep, Shiny has a problem with following her down to the bottom of the sea. Shoshana kindly helps Shiny get over her fear of diving deep. When Buddy expresses his feelings about being adopted to Tiny and Mrs. Pteranodon, they tell him that he will always be a part of the Pteranodon family. Mom takes Buddy and Tiny to meet another adopted dinosaur kid named Sonny Sauroposeidon, a huge tall creature, now a part of tiny Mikey Microraptor's family. Buddy and Sonny bond over being adopted and knowing that they are both in adoptive families that are different species but still love and appreciate them.

Erma Eoraptor - Buddy, Tiny, and Mrs. Pteranodon go on an expedition to find Erma Eoraptor, a member of the first species of dinosaur that ever lived. They venture off the beaten paths in the Triassic to find Erma, and then bring her back for a ride on the Dinosaur Train! Under the Volcano - Tiny, Buddy, and Mr. Pteranodon take the Dinosaur Train to Volcano Valley to see the local volcano. The sight is so spectacular, they go back for the rest of the family only to discover they've already gone to see the volcano! The merry mix-up concludes as the whole family meets up to marvel at the sight of Mt. Smoky erupting.

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.

The kids get to play in the snow and slide on a frozen pond for the first time. Cretaceous Conifers - The whole Pteranodon family have fun celebrating Mom's favorite holiday, Winter Solstice. They learn about large conifer (evergreen) trees and help decorate them at a holiday party.

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.

The plot thickens when they discover fossilized tracks that are millions of years old!

The Pteranodon kids and Dad get the idea to travel around on the Dinosaur Train and meet some of the biggest dinosaurs. They even sing a song, `The Biggest Dinosaurs', before meeting Allie Alamosaurus, an enormous, long-necked, plant eating sauropod who is very friendly. Allie explains that her huge, strong legs hardly bend at all, but she can still have fun playing games with the kids, and teaching them some of her favorites! Dad takes the Pteranodon kids on an overnight camping trip where they watch both a sunrise and sunset, learning that the sun rises in the east and sets in the west. The kids also find out more about nocturnal (night-active) animals, and diurnal (day-active) animals.

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.

When the Pteranodon family takes the Dinosaur Train under the sea to visit their friend Elmer Elasmosaurus, they learn that the Elasmosaurus family is going away from the station to follow their food, the fish. Buddy wants to follow, but the train tunnel doesn't go that way - so the Conductor decides to take the family in a brand-new invention, the Dinosaur Train Submarine! On their journey, they meet a marine reptile called Otto Opthalmosaurus, who guides the submarine deeper than it's ever been, and even helps them find their way out of a sea cave.
