Lower the flap, and see a friendly animalï, half's face! With a little help from Mom or Dad, baby can play peek-a-boo with a cat, a dog, a cow, a hen, a pig, a duck, and a lamb. A surprise appears at the very end of the book in the form of a little boy who holds a teddy bear up to hide his face. But when baby lowers this flap, a mirror is uncovered. Baby is looking at his own laughing face!
