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!

While riding the Dinosaur Train, Buddy and Tiny meet Dylan and Devlin Dilophosaurus, twin brothers with amazing double-crests on their heads.

The Pteranodon family is on the Dinosaur Train headed to the Big Pond for a special nighttime treat - watching a meteor shower in the sky! Mr. Conductor stops to pick up Erma Eoraptor, his best friend, whom he's excited to spend time with that night. At the Big Pond, the Conductor and Erma are interrupted a few times while trying to be alone, but soon find the perfect spot back on the Train. They watch the meteor shower from there, as our Pteranodon family watches the amazing meteors from the Big Pond beach.

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!

Derek the Deinonychus - Buddy, Tiny and Mom visit a family of Deinonychus, dinosaurs with large, sharp toe-claws. They meet a kid named Derek who uses his toe-claws to not only hunt with but to carve great art! Don's Dragonfly - Don makes a new friend with red feet, a dragonfly named Howard.

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.

The Pteranodon kids and their dome-headed friend Spikey Stygimoloch meet a brother and sister, Patrick and Pamela Pachycephalosaurus, two dinosaurs with enormous dome heads. Spikey bonds with the Pachycephalosaurus. Patrick and Pamela are athletes who invite our kids, Mom, and Spikey along to watch them use their impressive dome heads to play a volleyball type sport called, Dome Ball. Don has a large collection of things he's found in nature, but he's missing one hard-to-locate item - amber. On the Dinosaur Train, Don and the other Pteranodon kids find out that Gilbert is also looking for amber. At Amber Arroyo caves, Don and Gilbert separately search for and find amber, eventually bonding over their discoveries.

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.

Team Pteranodon travels to Dienosuchas Swamp to meet Deanna Dienosuchas, a 40 foot crocodile with many big teeth, and a crabby attitude. Tiny leads the way to warm up Deanna who turns out to be more friendly and less scary than our kids imagined. The Pteranodon kids have special visitors - their Grandma and Grandpa! 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.

A Spiky Tail Tale - Buddy and Tiny help settle an argument between Morris Stegosaurus and Alvin Allosaurus, two very big dinosaurs - one with a very spiky tail, the other with a mouthful of sharp teeth.

When the Pteranodon family travels back to the North Pole, Don declares that it's his "winter wish" to see snow fall again. When a big blizzard comes, and even the Dinosaur Train gets snowed in, Don worries that his wish brought the blizzard. He's especially worried for his new friend, Soren Sauronitholestes, who is sitting on a nest of her eggs, out in the blizzard. But everything turns out all right: Dad explains that wishing for something doesn't make it happen, and the well-adapted, warm-blooded, feather-covered Soren successfully hatches her babies. While visiting the North Pole, the Conductor suggests that the family stop off at Aurora Borealis Station on an enormous frozen lake to see the Aurora Borealis, where the Northern Troodons celebrate a "Festival of Lights." While the kids wait for night to fall and view the Aurora Borealis, they work up an ice-skating show to entertain Mom and Dad. Everyone joins in to sing "Solstice Time is Here" and skate under the lights!

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!

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. Home With Shiny & Don - Shiny and Don stay at home and we get to see that just because they don't always ride with Buddy and Tiny on the Dinosaur Train doesn't mean that they are not having fun. An adventure into a local caves leads to a marvelous and brilliant discovery.

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 Burrowers - The Pteranodon family rides the Dinosaur Train to meet a family of amazing, burrowing dinosaurs that live in holes and put on a "Cirque de Soleil" kind of acrobatic show every evening! Shiny's Sea Shells - Shiny, with help from Buddy, Tiny and Don, looks for the shiniest sea shells she can find, but ends up making a new friend named Henry, a hermit crab who lives in his own shell on the beach at the Big Pond.

The Pteranodon Family is excited to be going back to the "Classic in the Jurassic"! This time, it's a race between pterosaurs from each of the three Time Periods. The best part-all the family members will have a role to play in the race! Mom and Tiny will be in-air referees, Buddy and Don will do "play-by-play", and Dad and Shiny will man the start and finish lines. It's an exciting race as the pterosaurs fly between hanging vines, swoop through a canyon, push through a wind tunnel, slalom over and under branches, than carry food from a pond as they race to the finish line! Teddy Pterodaustro finishes first, but the race is contested when Remy Rhamphorhynchus (another competitor) protests that Teddy never retrieved a fish from the pond. Everyone is surprised to learn that the Perodaustro don't eat fish, they strain plankton through their bristle teeth. Teddy shows everyone how he does it to prove that he did indeed get food from the pond. Teddy is declared the winner! Buddy, Tiny and Mom are riding the Dinosaur Train when they bump into their old friend, Crystal Cryolophosaurus. She's on her way to visit King Cryolophosaurus down in Jurassic Antarctic and invites our family along. Mom and the kids jump at the chance, and upon arrival surprise King as he's singing a brand new song, Top Carnivore. King and Crystal's heartfelt reunion is marred when Crystal tries to convince a reluctant King to take this fantastic new song out on the road to share with his adoring Mesozoic fans. But King doesn't like leaving home and excuses himself to do some thinking. Buddy and Tiny follow and King sings a song called Good ol' Gondwana to explain his feelings about his home. Tiny has a great idea. King and Crystal can perform a live concert in Gondwana and invite dinosaurs from around the Mesozoic to attend! The concert is a huge success, and King is surprised and delighted when Crystal decides to stay there with him instead of going back out on the road.

The Pteranodon kids are playing a game called "I'm the Biggest," which raises the question: how big is the biggest frog? Dad takes the kids on the Dinosaur Train to find the biggest frog ever, the legendary Beelzebufo. Once off the train, they have to take a river raft to find this illusive creature, but find him they do. The kids are surprised that Benny Beelzebufo isn't nearly as large (or mean) as they'd imagined, but he is definitely the biggest frog they've ever seen! Benny teaches the kids about his "sit-still-and-wait" hunting style and shows off his large, floating leaf "home." The Pteranodon family rides the "Night Train" all the way back to the Jurassic Period to visit their nocturnal friend, Vlad Volaticotherium, who tells them that he wants to take them caving! Buddy, Tiny, Shiny and Don don't even know what caving is, but they are soon having a great time seeing all the beautiful stalactites and stalagmites that have formed inside the cave. They also learn that it can be a lot of fun to hear your voice echo down the cave's long caverns!

King Cryolophosaurus - Buddy, Tiny, Don and Mom meet a reclusive, singing dinosaur named King who has a big swooping crest on his head and a voice that sounds an awful lot like Elvis Presley. Buddy the Tracker - Buddy and Don are "footprint detectives" as they track and find creatures they know at the Big Pond. The plot thickens when they discover fossilized tracks that are millions of years old!

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.
