A pair of novelty board books by Salina Yoon features cuddly, plush covers befitting their subjects: Spooky Pumpkin and Black Cat. In the first, the titular jack-o'-lantern narrates: ""Watch me glow in the dark of night./ Boys and girls shriek with delight."" In the second, ""Dancing bones and vampire bat/ come out to play with Black Cat."" Exaggerated expressions help tone down the fright. (Sept.) .
