Plummy models himself a ship and a captain's hat and goes on a sea voyage. Pliff and Plops are envious, become pirates, follow him and capture his ship. As a huge octopus, Plummy gets his ship back while Pliff and Plops flee from the octopus to the nearest island. Luckily, they don't have to wait long: Plummy picks them up and takes them to the mainland!
