I don't understand what you mean by ?? is that the name of the costume. Well anyway you only give them a timeout when you check thyeir health and happpy. If they are both full or have a least one in it, then you give it a time out, other wise it will just scream and have anger marks around it...
i HAVE A CODE YOU CAN ENTE INTO YOUR TAMAGOTCHI v3 FROM THE DS 32479 91490.
In the DS game you run your own shops and you can take care of your tamagotchi too! :)
My gamestop is sold out though, I have it on reserve. I have the book that you get with the game there's so much you could do...
