Plik

 is a Ghoul inhabitant of Point Lookout. He runs a little hunting club out of the Costal Grotto, but it's strictly for high-rollers.

Plik has taken extensive notes on the anatomy of Feral Ghouls, and by reading his journal you will gain the Ghoul Ecology perk.

If you decide to join his club by paying the 1,000 cap entry fee, you can go on a safari. You can then kill him after the safari with no karma penalty to get your caps back. He will also have a Finger on him, if you have the Lawbringer perk. If you let him live however, you can participate in the safari again for 500 caps every day.
