You're prisoners. Three enormous worms came up out of the desert to watch you wrestle, and they want blood. Punch, kick, stomp the ones who are down, climb the piles of junk and dive off them, throw people into the piles. Bore the worms and they'll do something about it. Lose and you sit over the dunk tank while everybody throws things at the little circle. Get dunked and your wrestler spends a real week in the gross pit.
