With foam pages and 4 removable shaped foam objects, this is the perfect first puzzle book for bathtime, playtime, or anytime! Textures, colors, and recognizable objects keep kids engaged as they learn to identify the shapes they see all around them, like triangles, rectangles, circles, and squares! Pieces float or stick to the sides of the tub. Fit them back in the book, then read and play again!
