on my v5 celebrity kikitchi , my main tama grows until he fills the screen then shrinking to normal size... but it doesn't effect anything is he just having fun or something!??!
its just a cute animation. it either shows up randomly, or when you push c button (the right button) I don't have a celebrity v5 because my parents won't let me buy one with my money, so I don't know which one. but its most likely pressing c button.
