On your way to find Sandman for Captain Scarlett, you can find this mission on the bounty board in Oasis. Sir Hammerlock has a special request for you. An acquaintance of his seems to have had his face ripped from his skull by a nasty creature called Grendel (easter egg).

Travel a little ways north and you'll come to town tucked into the mouth of a cave. The cave is filled with many of the pirate types that you are likely becoming familiar with. If you take it slow, they should come at you slowly since they aren't particularly densely packed. Work your way through the town or you could simply run through to the cave beyond.
Inside the cave, you'll come to an underground oasis with some vending machines. Sell if you like and then walk around the outside of the oasis to the right. Eventually, you'll see a path leading further into the cave but it will be guarded by a Badass Pirate so be prepared. Take this path and you'll find a small stream leading away from the oasis. There will be another Badass Pirate along this path until you come into a much larger and longer part of the cave.
Start moving along this section of cave and on the left side you'll see an elevator that you can't activate yet. Across from this elevator is a waterfall. If you investigate the area, you'll find a ramp that leads up behind the waterfall. If you continue along this path, it will lead you right to Grendel's Lair.
When you drop into the Lair, Grendel will appear. Grendel is a very large, darkly colored Bullymong. Like all bullymong, Grendel is capable of doing some serious damage with attacks up close and can throw large objects from long range. Grendel also has the ability to rush at you. He will cover his face with his arms and then charge directly at you to try and bowl you over.
While Grendel may seem rather fearsome, he's still a bullymong just like any other. The strategy should be the same. Aim for his head whenever you get the chance and try to keep your distance whenever you can.
After killing Grendel, the exit from his lair will lead you right back to the beginning of Haytor's Folly. This will allow you to leave and turn in the mission or return back to continue with any other mission you may be on. Head back to the Oasis Bounty Board to turn this in.
