Catt, a cat, and Simon Cheddar, a mouse, land in the jungle after a skydiving school mishap. The two barely escape the diabolical monkeys, capturing and selling animals to a zoo, by mailing themselves home.
Back in Sweet Meadows, they contact their friends and classmates to devise a way to rescue their trapped friends—only to deliver them straight into monkey headquarters.
