It is theoried that the flesh pit is a giant creature currently sleeping, and that inside the flesh pit you are inside the organism. The fauna are the animals in the organisms body. They act kind of like the cells of a human body, but their animals instead. You know how to deal with them. The fauna are blind, but not deaf. So simply stay quiet when encountering one.
