Coastal grotto

 is a small cave in Point Lookout. It is where Plik lives and holds a "safari" of sorts with ghouls as the hunt. There are also two men, Jacob Humboldt and Rip Smithy, in the safari chamber, who will most likely die by the end of the safari. It only has one interior section.

Exterior
There is a buoy outside, just east of where the door to get inside is. The door itself is up the cliff side and you'll need to climb your way up. Also, there are some swamplurks nearby, so take them out first before you go inside. Out from the grotto underneither the buoy there is an Easter Egg of a dinosaur skeleton that you can dive underwater to see. Use the clear water glitch so you can see the bottom and you will notice 2 ammunition containers and a safe. The safe will contain caps and misc items and a scoped 44 magnum and the ammo containers 44 rounds and any random ammo.

Interior
Inside there is a long tunnel that leads you to Plik. Before reaching him, you'll find his room with a bed, a desk, and, his journal. If you start the quest, you'll be able to enter the safari chamber. The safari chamber is a large room where ghouls come out from all sides when you hit the button in the middle of the room.

Notable Loot

 * Mini Nuke
 * The Dismemberer

Bugs

 * If you set your mark on the location on your map, it will point to a small bush in Pilgrim's Landing.
 * Sometimes, while reloading a save in front of Pilk, he will be invisible.
 * Sometimes, the texture models may glitch within the Coastal Grotto. (confirmed on Xbox 360)
 * If you put on the ghoul mask and start the safari, the ferals will not attack Rip or Jacob even if you become hostile towards the ferals.
 * You can always pickpocket the caps from Pilk. If it fails, just simply press "select all" to take all the caps. Even if you are caught, you still have the caps, but he will get up to take them back. Before he does this, enter the utilty door and start the safari.
