Squidward
Tusoteuthis
The Tusoteuthis is a massive, aggressive squid found in the depths of the oceans. In battle, the Tusoteuthis can grab its prey and knock it unconcious, siphoning its blood to gain health. Once tamed, the ink from a Tusoteuthis can be used as a constant Oil source. Some survivors choose to hunt the Tusoteuthis for its Oil.
