When Benny the Ball wins a cruise to Hawaii through a boxtop contest, he and his pals board the SS Aloha Hooey, with five of the cats sneaking on as stowaways. Officer Dibble accidentally becomes a fellow passenger by chasing a counterfeiter on board. The gang finds a suitcase filled with (counterfeit) cash and they begin to live like kings, until Dibble catches them and tosses them into the brig. Top Cat devises a clever plan to capture the real counterfeiter, leaving Dibble and the cats free to enjoy the rest of their Hawaiian vacation.
