Okay, I've gotta ask with all of the llamas running around...no one's seen a woman named Yzma, have they? Tall, really wrinkly, wears a lot of purple, like almost more than I do? Turning people into animals, especially llamas is kinda her thing.
...Or it could totally be her son, Zevon. He's a bit of a jerk like that.
She has a daughter, Yzla, but last I heard from her, she was trying to do the whole good guy thing.
