   Summary

   You just wanted a break from your life. The work kept piling up, your boyfriend just broke up with you, your landlord was on your ass for rent -- All the bells and whistles. So in a moment of weakness you let your best friends pull you out for a night of debauchery and reverie at the club. Sexy makeup, tight dress, good music -- What could go wrong?

   Apparently a lot, because the next morning you wake up naked next to a skeleton monster in a room you don't recognize.

   Is that a trash tornado?
