The Ice Age Adventures of Buck Wild In an attempt to practice one of their extreme stunts, Crash and Eddie accidentally cause an avalanche and destroy the gang's summer habitat. Manny, Sid, Diego, and Ellie get mad at them, declaring they would not survive on their own. Wanting to prove them wrong, Crash and Eddie secretly leave their temporary camp while the others are asleep. Finding them gone the next morning, Ellie insists that they go search for them. Meanwhile, Crash and Eddie stumble upon the entrance to the Lost World, a land full of dinosaurs, and run into their old friend Buck, 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 finds out that Orson has covered the entrance with a boulder.
