Evolved cousin to the Chute Leech. These massive cephalopod-like creatures live in the dangerous liquid, where they hunt for small creatures that wander into their caves. They will often float just below the surface of the liquid, maintaining a 360 degree view of the surface with their large eyes. Despite their size, Octrolls are easily startled and will suddenly leap into the air, fluttering back and forth wildly to frighten potential predators. They will also use this tactic to leap on top of smaller organisms, grabbing hold of them with their large tentacles. Octrolls are communal and thought to be highly intelligent, but none has ever been captured for research due to their location deep within SR388.
