The Sultan of Zanzibar has a harbor infested with sharks, which makes it impossible for ships to trade with him. In an attempt to fix the problem, he brings twelve hippos into the harbor to keep the sharks away. His idea works well enough, but once the hippos are no longer a novelty and the people no longer feed them, they begin to starve. After the hungry hippos rampage through the city looking for food, Aban-Khan, the king's adviser, slaughters all the hippos except one, a little hippo named Hugo.

Members of the Wild Goose patrol decide to find the little monkeys stolen from the Zoo. They try to make up for what the unruly adults messed up. They keep bumping into the disguised damned ice-cream vendor, the intriguing Bagaméri, who would like to get the reward set for the finder of the monkeys.

A few kids make a circus show for their sick friend, and get in some trouble along the way.
