Duck is in a very grumpy mood. The pond is dry, and she doesn't want to roll in the mud with Pig, sing with Rooster, doze with Tortoise, eat laundry with Goat, or join any of the other animals in their pastimes.

Two prolific picture-book creators look to the skies for a humorous tale of not-fair-weather friendship.
