Learning about opposites has never been more fun -- or funny -- than with this winning board book. Yummy! Spaghetti is yummy, but worms -- and blue crayons, and sand, and other things too gross to mention -- are definitely yucky when tasted. Amiably illustrated in a bright, graphic style, Leslie Patricelli's spirited board book, Yummy Yucky stars an obliging, bald, and very expressive toddler who acts out each pair of opposites with comically dramatic effect.
