"I'm the Doctor." "And I'm a Princess!" I'm sorry about it begin mlp, but it doesn't really feel like it in this story. Don't be put off by the title either. It's the same Luna. I love Doctor Whooves! <3 Dr Whooves and Derpy/Luna. Can't decide really on that. So hard...

In Equestria, Twilight and her friends must go to Earth and become human in order to help Princess Celestia turn human again, and encounter several problems on the way.
