Team Huffleretards (a mock of Hufflepuff): Steve and Po.
Oddly a parody of Ravenclaw is absent from the academy. It is possible that SMG4 didn't have enough characters for four teams, scrapped the idea for another reason, or simply didn't know about Ravenclaw.
The motto of Hobowarts is: 'Magic *pig-like snorting*'
The name "Hobowarts" is a pun on "Hogwarts", referencing SMG4's running gag of putting hobos in his videos. While less likely, the name could also be wordplay of "HoboWars", an RPG where you play as a hobo.
