When the Sultan of Zanzibar wanted to rid his harbor of sharks, he imported a dozen hippos for the task. They succeeded...and the Sultan's minister hunts them down instead of seeing to their care. The one escapee─young Hugo─is shielded by kindly children, but how long can they succeed in hiding him? Animated effort from Hungary, and kiddie favorite of home video's early days, features the voices of Paul Lynde, Robert Morley, Burl Ives; singing vocals by Jimmy and Marie Osmond. 91 min. Widescreen; Soundtrack: English Dolby Digital mono.
