It's Chelsea, who lives across the street. She's a little stuck-up, with rich parents and a nasty attitude towards other people on the street.
You decide to give your supposed powers a whirl. With just the most minor inflection of effort, the changes begin immediately. Chelsea stops in her tracks, and begins to look around in panic.

Chelsea steps out of her discarded clothing and patters along the sidewalk, unsure what to do next.
This is going to be fun, you think...
