The Gut Worm is a parasite that infests and controls the thoracic and abdominal cavity of a corpse. It reanimates the corpse using eyed tendrils and forms a bile sack on the back. When the corpse is close to its victim the worm will disembowel the corpse from the inside and vomit caustic bile towards the victim. The bile sack can be ruptured and spill on the corpse dissolving it.
