Witzy lazily rolls over onto some blueberries, getting a funny stain on the back of his head. It gives Ellie a jolt, because it looks like Witzy has another face! This gives Witzy an idea—he will play a joke on his friends. He startles each of them in turn with his blueberry face—causing Patches to step on the train, Boof to drop the donut, and Lulla to get the sock dirty. Instead of thinking it was funny, the friends apologize to Witzy. Oh, no! It made Witzy sad to think his joke caused them unhappiness. So to cheer everyone up, they all enjoy eating blueberries together.
