That Is Not a Good Idea! is a hilarious, interactive picture book from bestselling author and illustrator Mo Willems, the creator of books like Don't Let the Pigeon Drive the Bus, the Knuffle Bunny series, the Elephant and Piggie series, Goldilocks and the Three Dinosaurs, and many other new classics.

Inspired by the evil villains and innocent damsels of silent movies, Willems tells the tale of a hungry fox who invites a plump goose to dinner. As with the beloved Pigeon books, kids will be calling out the signature refrain and begging for repeated readings. The funny details in the full-color illustrations by three-time Caldecott Honoree Mo Willems will bring nonstop laughter to story time.
