The Pteranodon family takes the Dinosaur Train to ADVENTURE ISLAND, a brand-new theme park on a volcanic island. The Conductor’s arch rival Thurston is in charge: he proudly shows off the park’s amazing ROBOT DINOSAURS! They’re steam-powered, driven by the volcano’s thermal pressure. Things go wrong when an earthquake causes the pressure to get too high and the malfunctioning robots to go rogue. It’s up to Buddy, Tiny, Shiny, and Don to navigate safely across the island and reunite with their parents.
