Lil Elvis and the Truckstopper (1997)

Li'l Elvis wants a pet but his mother thinks he's too irresponsible. Li'l Elvis discovers Sea Monkeys, the perfect low maintenance pet at a really cheap price. After buying them and realising they're just wriggly bits of algae, Li'l Elvis abandons his pets and gets transported to the Sea Monkey world, where the Sea Monkeys are determined to make him pay. Meanwhile, the town watches Herb "Brittle Bones" Petrankovic's attempt at a new land speed record.
