Percruel lurks near the shallow waters of oceans, waiting for large gatherings of people. Its greedy nature compels it to appear before these groups and use its many tentacles to steal as many shiny baubles as it can to hoard for itself.
It lives in complex rock formations on the ocean floor and traps prey using its 80 tentacles. A Percruel's six bold whiskers sense air movements to determine what is in its vicinity.
