Coastal grotto

 is a location in Point Lookout. It is where the player meets Plik, a ghoul who hosts a "hunt" of sorts. Also in this location is Plik's Journal, which, upon reading, grants the player the Ghoul Ecology perk.

Loot
There is a Mini Nuke in the first room to your right after you enter.

Nearby
Outside the Grotto swim South East to the buoy on the right. When you are at the buoy swim down under and you will find the remains of adinosaur that look like a T-Rex. The loot is leveled but typically will have a combination of .44 rounds, an axe, two or three baseballs, 60&#160;to 90&#160;caps, some pre-war money, a camera, and three scoped .44 magnums. There is a dead body as well holding to a lever-action rifle and two ammo crates. The nearby buoys hold loot as well.

Appearances
appears in the Fallout 3 add-on Point Lookout.

Bugs

 * If you set your mark on the location on your map, it will point to a small bush down in Pilgrim's Landing.
 * Sometimes while reloading a save in front of Pilk, he will be invisible.
