You have to get one!!! they are really good. there are several new tamagotchis,new skill points, and that tells what adult youll get,there are jobs,which are the adult minigames!I have 2, ones a pyonkotchi,and the other is a togetchi.
I was playing Get *musical note* on my Tamagotchi and Mum told me to get some kitchen towel for her. But you can't stop my Tamagotchi, and saying "wait a minute" doesn't work either, because she NEVER listens!
