Mr. Gumpy lives by a river. One sunny day he decides to take a ride in his small boat. It's such a perfect idea that soon Mr. Gumpy has company: first some children, then a rabbit, a cat, a dog, a pig, a few chickens, and a sheep. Will there be room for them all on Mr. Gumpy's small boat? The highly patterned text builds to a climax both expected and hilarious.
