"These weird monsters are omnivorous scavengers, not at all hesitant about adding a bit of fresh meat to their diet of dung, offal, and carrion. They hate direct sunlight or bright light, so they are found underground in most cases. Usually (90%) only a single individual is encountered, for otyugh typically live in partnership with other subterranean monsters. The otyugh will dwell in a truce state with other powerful monsters in order to scavenge droppings and other leavings. In most cases otyugh live in piles of dung and rubbish, and thrive there. The otyugh has a sensory organ stalk and two tentacle arms which protrude from its hideous body. The eyes are always thrust above the offal the creature lairs under, and this prevents surprise. Its tentacles have sharp ridges and are used to deliver smashing blows to prey. The creature’s mouth is sucker-like and filled with many teeth. If it bites any victim it is 90% likely to be infected by disease (typhus). These monsters have no interest whatsoever in treasure as humans know it, but their partners may, occasionally making the guarding of treasure they value a condition of allowing otyugh to dwell in semi-symbiosis with them. Otyugh speak their own language and are semi-telepathic, thus often able to communicate with other life forms when the otyugh so desire." AD&D MM (1978 Printing)
