Pigfarts for sure! Why?
1) It's on MARS!
2) The headmaster is so much better than Dumbledore
3) His name is Rumbleroar
4) He's a lion
5) That can talk
6) And if you get good grades you can ride around on Rumbleroar's back
7) Plus with Voldemort destroying the whole planet, you may be rethinking Pigfarts, huh Potter?

Allow me to conclude with Pigfarts, pigfarts here I come! Pigfarts, pigfarts, yum yum yum!
