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, walk down the "hallway" and speak 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.

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 the pathways.

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.
