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?

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?
