In Up the Wall (p. 727), Nicholas Heller depicted a small boy wandering the ceilings; similarly, Keller's ``little Mott Turner'' finds gravity reversed (but only for him) after he emerges from the under (``wrong'') side of the bed. With smoothly rounded forms in vibrant, sophisticated colors and a bold, surreal style, Keller distorts perspectives for a vertiginous feel that recalls the world seen when blood rushes to the head; the popeyed Mott is an appealing, expressively stylized figure who ``falls'' high into the sky before ``what goes up, must come down'' and he lands on the top side of his bed. Heller and Keller make an intriguing pair, each bringing his distinctive style and imagination to a situation guaranteed to amuse kids. (Picture book. 3-7)
