The Pteranodon kids are riding the Dinosaur Train with friend and fellow pterosaur, Quincy Queztalcoatlus. When they pass by a waterfall, Buddy comments on how big it is! Quincy’s dad mentions a giant waterfall at the edge of the Western Interior Sea. Mr. Conductor gives a lesson about waterfalls and then suggests a unique and amazing way to view the giant falls – from above! They can fly in the experimental Dinosaur Train Zeppelin…if Thurston Troodon will agree to take them all there on the zeppelin’s maiden voyage. Thurston does and our Pteranodon family gets to experience a spectacular zeppelin ride! The Queztalcoatluses fly alongside, impressing everyone with their flying abilities. After learning more about waterfalls, the Pteranodons catch lots of fish and dine before heading back to the Train via the one-of-a-kind Dinosaur Train Zeppelin!
