Each foam-padded page is constructed of sturdy, floatable vinyl, and shows a picture of a friendly land or sea creature. When kids dunk these books into the bath water they get a big surprise: the animals change their colors! When the pages dry out, the animals return to their original white. Each book comes packaged in a transparent plastic bag with a hanger card. Bathtime is always a splash as sea lion claps, penguin jumps, swan glides, and more.
