Japanese illustrator Taro Miura brings his bold, whimsical graphic style to a board book for the very young. A duck’s fluffy . . . bum bum. Perfectly positioned over the center of each spread, the posteriors in this simple and simply hilarious book showcase an array of creatures. And each one has a distinguishing characteristic: the pig’s is round, the elephant’s is big, the monkey’s is red — and the toddler’s diapered behind is the cutest of all.
