Grimjaw Slugface is a resident of BBQ Bay, first appearing in "Shadow of Israphel" Part 18: Swampy Away!, alongside Angus Eyeless and Jock Fireblast. Xephos and Honeydew overhear their heated conversation whilst exiting the secret tunnel leading from the archery range at Verigan's Hold. Grimjaw is said to be "tainted" by Jock Fireblast. He attacks BBQ Bay and destroys a bit of it, but his ship is sunk and he is apparently killed. His Treasure Hold contained a large amount of gold, as well as a piece of Karpath's Map, but was also filled with puzzles, traps, and monsters. The entry point was on Scumbucket Island, with the exit point in a desert located near BBQ Bay, The Tomb of Lehparsi, and The Stone Dragon.
- It has been suggested that Grimjaw was a cultist, since there were Zombie Pigmen on his ship and Angus Eyeless claims he was "tainted", as in the Taint of Israphel, but these rumors are not confirmed.
- His Treasure Hold contained a map fragment for Karpath's Map, which is now complete.
- If both Grimjaw and Jock were part of the Cult of Israphel, they might have fought because Grimjaw had become a traitor.
- He has the appearance of Marvel character Nick Fury. Despite the obvious eye-patch, he has an outfit that looks similar to that of the pre Avengers:Unlimited Nick Fury and a similar hair-style to the a fore mentioned version.
