My Patronus is a Dolphin
Your patronus takes the form of a Dolphin. A dolphin is both very playful and friendly. Like a dolphin, you are joyful, intelligent, and very funny. You enjoy life, and like to help others. You have so many happy thoughts that you can easily perform the patronus charm. Casting the charm becomes somewhat more difficult during a battle, but your concern for your friends helps you keep your focus.
