After a Viola molts, it becomes a Multiviola, the large, spherical protoplasm that live in the fiery depths of Ridley’s lair beneath Norfair. Multiviola move through the caves and tunnels of the hideout at high speed, bouncing off the walls and ceiling, making them very difficult to dodge and dealing massive amounts of damage. They are products of the life force Mother Brain breathes into the molten rock.
