Mo Willems’s fans will be delighted to know that he has a new picture book available, entitled That Is Not a Good Idea! (Balzer + Bray, $17.99). The story unfolds like a silent movie with color images interspersed with dialogue on black pages. A dapper male fox meets a demure female goose. The two strangers take a walk through the woods and then decide to have lunch. The audience, comprised of six delightfully cute baby chicks, continually interjects, yelling, “that is not a good idea” at the screen. Like all of Willem’s book, this one has a twist, but just when you think you know what the twist is going to be the story twists off in a completely different direction. Although younger children might not recognize the silent film motif, they will appreciate the humor of this story. Pigeon lovers should make sure to look closely; as usual, he makes a cameo.
