There are six different characters: Mini-Muak, Mini-Pinky, Mini-Yummy, Mini-Boo, Mini-Cute and Mini-No Come with diapers and potty with fun design. Check the Pee-peepedia to see how careful to apply it. Battery operated without batteries, unscrew the head and fill it with water as many times as you like. The tempera's inside the Mini Bellie.
