The Island of Parrots Cesare discovers an old map leading to buried treasure on a remote island, so he steals a cruise ship to get he and his pair of henchmen there. Tommy, Oscar and Yukari are also on the cruise ship, courtesy of tickets provided by Professor Leonard. They discover the ship has been hijacked, but are thrown overboard before they can rescue the crew. Thanks to Oscar's ability to change into different shapes, such as a life raft, they follow the cruise line to a remote island and help the native islanders battle the crooks.
