You invited all of your friends from the Academy, to your dorm room. That's right, all. Apparently you really looked at six traumatized college friends, none of whom are human, and really thought, "Damn, smash, smash, smash again, double smash, and absolutely smash".

Then again, I looked at my own six traumatized monster academy college friends and went, y'know what? SMASH. Besides, polycules are fun, you can totally summon wayyy more zombies on campus with six people helping you. Plus, imagine the tax benefits?
