Buddy and his dog Bozo are sailing to The Lost World. While there they encounter dinosaurs and cave people. Bozo trips a cavewoman jumping rope then trades sniffs with a caveman who acts like a dog and digs up a bone. As they investigate the island, one of the dinosaurs takes a liking to Buddy. One of the cavemen captures them and throws them in a kettle to be cooked. Buddy cries for help and his dinosaur friend saves them.
