Peek-a-Boo Monkey: These shy little guys cover their eyes, just waiting to play a game of peek-a-boo with you. They are just too cute to put down. Each is 3" tall and 2" wide and made of soft vinyl. Give a little squeeze to their sides and arms open just enough to see their eyes - peek-a-boo style. Turtle and monkey available. You may need both so they can play together and strengthen users palmer arches and fingers in both hands.
