"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

Triassic Turtle - Don mistakes a shell for a rock and meets Adam Adocus, a turtle with a head he can pull into his shell.

Long Claws - Buddy, Tiny, Don and Mrs. Pteranodon head to the thicket to ask a Therizinosaurus family about their colossal claws. Mr. and Mrs. T strike a pose to demonstrate how they use their claws for self-defense, while their daughter, Teri, shows the kids her favorite practice spot.Tank's Sleep Over - When Tank spends the night at Pteranodon Terrace, the last thing he wants to do is sleep. But as the night wears on, Don, Tiny and Shiny start to nod off, and Buddy tries to stay awake with Tank. Then Buddy realizes that Tank is worried about sleeping in a strange place, so Buddy and Mom help Tank feel at home so he can finally get to sleep.

"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).

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.
