Ok, said it before, i'll say it again...
A sorcerer mickey robe to go WITH the ears.
and a santa mickey hat. The christmas trees got the hat, we players did not.
and, on an unrelated, and utterly crazy note, i'd like to see a Mr/Mrs potato head magic. You turn into a potato head for say, a minute, and other people can come up and click on you and then somewhere else on you to swap pieces. you know, click on an ear, then on a nose and wham, you have a nose on your ear and an ear on your nose, stuff like that.

or maybe a menu comes up with different potato head pieces in it (hats, eyes, noses, mouths) and people can just change what you look like for that minute.
