Rotjaw is the second to final boss of Hell Creatures Rotten Corpse - Beyond Hell. It moves across the ground, trying to trap Knight Richard. Its teeth will destory any weapon, making its flesh the only vunerable spot.
Blood Spew: Rotjaw will spew blood from its mouth.
It is best to constantly move against this boss, mostly attacking from the back when the oppurtunity is available. Try not to stay directly above it or you can be damaged by its blood spew.
