Desc: Hugó, a víziló: Directed by Bill Feigenbaum. With Burl Ives, Robert Morley, Paul Lynde, Jesse Emmett. The Sultan of Zanzibar has a problem--his harbor is infested with sharks. To solve the problem, he brings in twelve hippos to keep the sharks away, and it works. But once the hippos are no longer needed, they become a nuisance and are massacred by Aban Khan--all but one little hippo named Hugo. What will become of the last of the Zanzibar hippos?
