The King Gurgler commands the Fishmen on an island south of Catun called Fishman Island. He can be found in the Island Lab on the most south-western tip of the island.
He wields a Meitou grade Combat Cleaver and is a deadly foe.
His Gurgler Head can be looted from his body and sold to collect on his bounty. Looting the head from his unconscious body will result in his immediate death.
