Roly-Poly Egg is a lively book that centers around the rainbow spotted egg of Splotch the bird. Somehow the egg gets bounced off the tree and goes on an adventure of its own. The reader is invited to use his or her finger to follow its travels as it encounters different animals by tracing the raised dotted line. In the end, Splotch manages to get the egg back before it hatches — and the reader gets to reveal the chick inside by lifting the flaps.
