Gibbering Mouther Ravenous Chorus of Unreality Habitat: Underdark Treasure: None Gibbering mouthers endlessly feed on and regrow their own amoeboid bodies-amorphous heaps roiling with eyes, teeth, and strange organs. These mind-bending terrors sing and scream, laugh and cry with a cacophony of voices ranging from disturbingly unnatural to shockingly familiar. They exist only to feed and to unleash their disdain for reality, their many maws dripping with otherworldly spittle. Gibbering mouthers come into being in various unpleasant ways.
