Dumbledore? What an old coot! He's nothing like Rumbleroar!
Rumbleroar
The imaginary headmaster of the Imaginary Wizarding school on Mars, Pigfarts. He is a Lion who can talk, and will let good students ride on his back. There are no dances at Pigfarts, because they would wake Rumbleroar's cubs.
I'm going to Pigfarts. The Headmaster is Rumbleroar. He is a lion, who can talk. ~Draco Malfoy
