"Does a mouse have a green spiky tail?" the book asks, showing a portion of some animal's body that fits that description. When we turn the page, we can see and read the answer: "No, but a crocodile does." The answers to these yes-or-no questions are pretty obvious and young children will not only enjoy getting all the answers right, they'll also enjoy the humor that comes through incongruity with questions such as "Are these the feet of a pussycat?" next to a picture of an elephant's feet. Melanie Walsh's use of bold colors, amorphous shapes and painted black letters is reminiscent of the work of Lucy Cousins. (Ages 18 months-3 years)
