I'd always heard you don't exactly get to PICK what animal you learn to be. So you might study, and then turn into a tiger or a crocodile or something else really noticeable.

I'd love to learn how to do an animagus tranformation. The Headmistress is an animagus? Really? Have you ever seen her transform?
