Composed of slime and congealed mucus, these human-shaped monsters wrap themselves around their prey and start dissolving armor and flesh. Bones and trinkets from past victims can often be seen sticking from their glutinous bodies.

During the Second Age of Magic, mucusoid-porridge hybrids were fashioned by a certain old woman with green skin, a wart on her nose and a huge, pointed black hat.

During the Great Monster Uprising, mucusoids were reported in the following regions: Flathead Fjord, Mirror LakeTidal Flats, Miznia Marshlands, Miznia Jungle, The Lost Castle of Y'Syska, Discipline Beach, Crab IslandThe Glass Maze, BozbarlandLargoneth Castle, and the G.U.E. Tech Training Grounds in the Ethereal Plane of Atrii.
