A little rat who keeps trashing you on everything you do. They insult you but then say sorry after. But they don't mean it. Sometimes they get really aggressive, they may pinch and slap but it's all in good fun. They're quite stylish and can pull off multiple looks. Has trouble being nice sometimes but if you catch them on a good day it's all good.
