Ghost Pirates of the Sea-erra Madre

You spend the next few months exploring the ocean with Nerita. Your ability to swim quickly improves and you are able to move around far easier than when you were restricted by your seasuit and submarine.

One day the two of you find yourself in a twisting series of caves. You lose track of Nerita and come out into a larger space with four other exits.

Warm water comes out of the small hole in the floor, light spills down from the hole in the ceiling, the hole to your right is strangely dark though has a small light floating in the darkness, and the hole to the left seems really boring.
