New pet

My cake had a tamagotchi on it, which works! It self selected rabbit out of the 100+ things it could be (including human?) probably because it was keen to fit in in this household. I'll be honest I've no idea how to keep it alive, I've pushed some buttons but I'm not sure what that's done. It's been alive 24 hours though so perhaps I'll just keep pressing random buttons when it beeps.
