Monkey has a box and tells his friend, Cake, that there is a cat inside. This cat is magic, though. If the box is opened, he disappears! Cake questions this logic and he and Monkey have a spirited discussion about it. Cake is sure that there is no cat in the box, because there is a magic dinosaur in the box. And, this dinosaur disappears when the box is opened. The two friends eventually determine that they will never really know and walk away toward some pie. After they leave, a cat peeks out of the box and rides away on a dinosaur’s back.

This cute nod to Schrodeinger’s cat has simple illustrations on uncluttered pages, reminiscent of Mo Willem’s Elephant & Piggie. The text is dialogue and each character has a different color of speech bubble, making it easy for the reader to determine who is speaking at any given time. The friendship is real and they can agree to disagree in an amicable fashion, which is a lesson in itself. Early readers will enjoy the story and the characters and wonder themselves about the contents of the box!
