It's a long shot, but every time I wear the Ram Hat, I wish I could give someone a headbutt for giggles, but it'd only work while wearing the ram hat. And it doesn't have to be visual, it could be something like "Ayasta headbutted you. You giggle. +10 mood" or something. Maybe roaring for dragon outfits, "Arrrrrrgh" for pirate types. You get my meaning. Could even go for whole outfits.
