When Crash and Eddie stumble upon the entrance to the Lost World, a land full of dinosaurs, Ellie insists the gang search for them. Crash and Eddie run into Buck Wild, who saves them from raptors and tells them that a Protoceratops named Orson, who was bullied when he was young for having a massive brain, has escaped from exile and has come to conquer the Lost World. Buck tries to get Crash and Eddie back to their home, but find that Orson has covered the entrance with a boulder.
