The Mini Bellies Color Pee Surprise are the adorable little brothers of the Bellies who pee color, just like a rainbow. There are six different characters to collect: Mini-Muak, Mini-Pinky, Mini-Yummy, Mini-Boo, Mini-Cute, and Mini-No. Each Mini Bellie comes with diapers and a potty with a fun design. Refer to the Pee-peepedia for care instructions. These battery-operated toys do not require batteries; simply unscrew the head and fill it with water for endless play. The tempera inside the Mini Bellie can be used approximately 30 times.
