When it's time for baby doll to stop wearing diapers, it's time to learn how to use the toilet and Corolle's interactive toilet is ideal for the task. The lid opens and closes and the flush button activates two sounds -- that of baby doll going on the potty and of water flushing. Requires 3 AG13(LR44) batteries (included). Ages 3 years and up. (Doll not included.)
