Does anyone know a mod where I can turn any accessory into something else? Like a hat or a wig into a guitar or fire for all players? I once saw a level 2 guy doing this; I was an admin on a big server, and the guy with a wig managed to turn it into a guitar that was extremely rare and everyone could see it. Even when using the /info accessory command, it showed the wig, but in view, it was the guitar.
