Plik's Safari

 is a Fallout 3 quest which is added to the game with the Point Lookout add-on.

Walkthrough
When you enter the grotto, loot the small room on the right and be sure to read Plik's Journal, (on the desk), before continuing down the "hallway" and speaking to a ghoul named Plik. He offers you a chance to join his little hunting club, but only if you pay the entry fee of 1,000 caps. Pay the fee, and ask to join in the next Safari. NOTE: Do not wear the ghoul mask as you enter the arena, the game will not trigger the quest if the ghouls are not hostile torwards you.

Join the safari
Enter the door behind Plik, and meet your buddies for this hunting excursion, Jacob Humboldt and Rip Smithy. When you are all set to begin the hunt, flip the switch on the block in the center of the room.

Survive Plik's Safari
You'll have to fight several waves of leveled Feral Ghouls, ranging from Swamp Ghouls to Feral Ghoul Roamers. Jacob and Rip are hardly worthy allies, and will usually perish during the onslaught. Use anything at your disposal to live through the obscene amount of enemies. It's not a bad idea to place mines on all of the three pathways extending from the center where the switch is located.

Collect your reward
After the last Feral Ghoul stops breathing, the Safari is over. Walk out the way you came in, and talk to Plik to get your reward: a unique Axe Plik pilfered from one of his club members "who won't be needing it anymore", The Dismemberer.

Reward
The Dismemberer and 100 XP. You can kill Plik and get your 1000 caps back (plus the 800 he had before) if you so desire. This can also be done via pickpocketing.
