Well, the centaur change is the only one under the person's control. So she could be a centaur whenever, but be a wolf during a full moon and a rabbit when she's scared.

Which means she could change into two or three at the same time. Which she finds really embarrassing, but her daddies tried to teach her was nothing to be ashamed of. It won't be until she meets the daughter of penguin!Radek and werewolf!Gil Grissom and...and...I got nothing for the third. I'll have to write something new. Anyhow - they fall madly in love and share their pains and frustrations with never knowing what to wear because you never know what body you're gonna end up the day in.
