Princess Celestia: A phoenix is a majestic and magical bird. While it appears healthy and happy most of the time, every so often it must renew itself by shedding all of its feathers and bursting into flame. Rather melodramatic, if you ask me. It then rises from the ashes, fresh as a daisy. All just a normal part of the life cycle of a phoenix. I'm afraid mischievous little Philomena here took the occasion to have a little fun with you, Fluttershy. Say you're sorry, young lady.
