Behind the BIG TREE is a little tree. Behind the BIG DOG is a little dog. Pop out each soft, colorful, nontoxic foam piece to discover the difference between big and little. Children can remove the shapes of a house, car, tree, and dog, and then easily press them back in. The shapes float--in fact, so does the entire book!--so they"re perfect for bathtime, not to mention bed, travel, or any old time! Check out Animals, Counting, In and Out, or any of the other titles in this terrific series. (Ages 1 to 4) --Emilie Coulter
