One sunny day Mr. Gumpy decides to take a ride in his small boat. It's a perfect idea for a lovely summer day, and soon he is joined by children, a rabbit, a cat, a pig, and a host of other friends. But when the goat kicks, the chickens flap, the dog teases the cat and the children squabble -- the boat tips into the water and everyone tumbles out. No one minds getting wet on such a nice day, though, especially since Mr. Gumpy invites everyone to his house for tea.
