The Final adventure. As the young people reach adulthood, things change; everyone changes. Sir Captain Slippery Jack Maverick marries Captain Beatty Bonney-they become "Captains Outrageous!" It's off to the Ghost Island for a honeymoon, and the whole cast comes along to find an island not on any map-except for an ancient one on sheep's skin. There are ghosts, all the inhabitants are ghosts, but they are all trapped by an evil curse, and Lady Molly Catherine and crew decide to save them all, but there is a time limit: "Before the Moon Eats its Tail!"
