Mikey tried to figure out what to do. It wasn't easy, realizing that you couldn't wear your own clothes, and suffering from a lack of alternatives. It wasn't like he was going to wear his mom or sister's clothes.
Apparently, immunity or not, the urge to fulfill the terms of the wish was too strong, and Mikey blacked out, and when he came to, he was already dressing in a strange room he'd never seen before.
He thought maybe the wish had teleported him, however, the dirt on his bare feet indicated he'd walked here...wherever here was.
As soon as he finished dressing, he felt relaxed, as the magical compulsion faded. He looked down, to see what he had done.
