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 magically change their colors! When the pages dry out, the animals return to their original white. In Blubb, Blubb!, underwater adventures abound as dolphin leaps, frog hops, seahorse dives, and more. Each book comes packaged in a transparent plastic bag with a hanger card.
