Squirrels Elliot, Crash, Chip, and Twitch try to rescue the stuffed animal Mister Nibbles when he is taken indoors to the house across from the park.

The Walnut Cup, the only American stop on the World Squirrel Soccer League tour, is taking place in Elliot's park. When the game ball, a perfectly round walnut, cannot be found, it is up to Elliot and his friends to find it.
