Alternating die-cut pages transform one featured shape into a vehicle with the flip of a page. A circle on a bicycle becomes a hot air balloon. A triangle becomes the sail on a sailboat, then a blade on a bulldozer. An oval is first a submarine, then the cab of a helicopter. Square becomes train, becomes truck. Rectangle becomes bus, becomes red wagon.
