Munchkin - Munchkin Arm & Hammer 3-in-1 Potty Seat The Arm & Hammer 3-in-1 Potty Seat by Munchkin is a complete potty training system with the odor-eliminating power of baking soda - because sometimes potty training can stink. This versatile bathroom buddy can be used as a potty chair, removable trainer seat, and a sturdy stepstool. Includes a replaceable freshener insert for odor control and one 36 pk of 4"x7" Arm & Hammer flushable Potty Wipes (refills sold separately). The bowl removes for easy cleaning and the no-slip bottom prevents the potty from sliding around.
