Inspired by the hat mechanic in SM64 DS

You have a special power. If you wear the headgear of someone else, you will shapeshift into that person. You will look and sound like them, and you will even have their skills and be wearing their clothes. The Headgear can be pretty much anything-any kind of hat or cap, head Bows, headphones, Crowns, Hairclips, or anything else typically worn on the head. If the headgear comes off, you transform back into yourself.
