Oh, no! The Cat in the Hat has lost his famous red-and-white-striped hat in the Forest of Wagamaroo! Can Sally and Nick help him find it on the darkest night of the year? It looks unlikely until a trio of nocturnal animals—a sharp-eyed owl, a keen-eared bat, and a scent-sensitive opossum—show the Cat and kids how to do so. Based on an episode of the new PBS Kids program The Cat in the Hat Knows a Lot About That!, this 16-page Pictureback comes with a sheet of glow-in-the-dark stickers, ideally suited for nocturnal play.
