A giant slug that's 7 feet long, nearly 5 feet wide, and weighs at least 300 pounds. It's black, but sometimes have patterns along its skin, or even spiky or bumpy growths all over. This slug stalks prey that enter the water, moving just fast enough to be undetected. When close to its prey, it secrets a mucous with a paralytic chemical inside of it, paralyzing any unassuming prey. From there it either eats, or during mating season, it will mount them and try laying eggs into them. The slug has a long, blunt, tapered ovipositor that lays eggs the size of a chicken's. It doesn't discriminate on the prey in question. After mating, it will either go away or, in the worst case, take a liking to the prey. It will then smother the prey to unconsciousness and bring them with it to its den, an underwater cave with an air pocket. From there, it tends to the prey and keeps them as a broodmother.
