The story unfolds through a series of questions and answers. The rabbit is asked question after question. As the story moves between question and answer, flat and dimensional, children naturally slip into a magical world of imagination. By recreating the rabbit's newly invented creations in their own minds, they engage in even more sophisticated thinking. The author never lets go of the thread of imagination, right up until the last page. "Please do not turn upside down"? But why? While grown-ups puzzle over it, children will be the first to find the answer. Winner of the 2007 Dr. Seuss Award.
