Andy and Charlie are passengers on an ocean cruise ship. Midway through the cruise the ship is attacked by a 17th Century sailing ship with a crew of pirates under the command of Captain Kidd, who died 250 years earlier. Andy and Charlie sneak aboard the pirate ship and are taken to their island headquarters, along with a girl from the cruise ship. Andy comes up with a plan to defeat the pirates (who really are ghosts!); An elephant at a zoo eats Andy's straw hat and Andy gets scolded for feeding the animals.; Andy's duck decoys don't attract any ducks when he's out hunting, but ducks flock to them when he gets home.; A supposedly-stuffed bear at a museum only strikes a ferocious pose when someone is watching.
