Simple animal movements--the waggle of a tail, and the waddle of a walk--are the basis of this book (and its companion volume Can You Peck Like a Hen?, ISBN 1-56402-881X). They're replicated so perfectly that even babies will be thrilled watching these big, approachable animals move. Sturdy pop-ups, hidden mechanisms, and heavy stock ensure that the kangaroo's leap can be repeated many times in the future.
