Growch was the steersrat of the Seascarab. He hated Badrang the Tyrant as much as his captain, Cap'n Tramun Clogg.
When his captain made a failed attempt to seize Marshank, Growch was among those who betrayed Clogg to become new soldiers for Badrang. As he was a minor character, not much is know about him, though he most likely died in the Battle of Marshank.
