Shooting hoops in his driveway with pal Charley, Harry gets a taste of the high life and when the rain puts a stop to his game, he hops into the bucket to Dino World to seek a place where he can jump around all day long. Although when he arrives in Dino World he decides that he would like to be able to jump higher, so Harry and the Dinosaurs board the rocket ship to jet them to the planet Boing. On their visit, the gang enjoy some high times indeed, as they become friends with a native Boingian and learn that bouncing is pretty much the local pass time.
