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?

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?

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?

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?

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?

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?

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?

Mrs. Pteranodon organizes a “Mom’s 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.

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?
