Fleshrooms are fleshy creatures that outline the walls of small rooms in various levels of The Backrooms.


Fleshrooms are creatures that carve out rooms in various levels of The Backrooms, and live in those rooms. They rely on trapping prey and move very slowly, but, if caught by one, it is almost impossible to escape.


The rooms that fleshrooms are inside are always rectangular, and are lined by the fleshrooms completely except for the door. It is unclear whether the door is part of a fleshroom, as it is always a pale brown colour, as if eroded over time. The actual fleshroom outlines the walls of the room it's in, and is usually 1–3 metres thick. They are a pale red colour, and the flesh itself is very smooth. However, fleshrooms also have several eyes, ears, noses, hairs, nipples, nails, and other superficial features wanderers have. The older a fleshroom is, the more of these they have. There is also a singular large mouth at the bottom of the fleshroom, although this is not used for consumption of prey. Fleshrooms smell extremely foul, and they can be noticed from a distance by this. They can also be noticed by their loud breathing noises. There is not much diffusion between the fleshroom's hiding spot and the rest of The Backrooms, so they must breathe heavily to get enough oxygen. However, this can also work for them, as insane wanderers will often think the smell is something much nicer and will think the breathing is coming from a wanderer. Unfortunately, insane wanderers are the least likely to escape fleshrooms.

Social behaviours

Although fleshrooms do not communicate with each other, this does not mean they are solitary creatures. Fleshrooms frequently hold conversations with wanderers they capture, and are able to absorb thoughts from wanderers if they are consumed.



Fleshrooms are found outlining small rooms within a variety of levels. Upon “claiming” their room, they use acid to corrode the walls, and make a place for themselves. Fleshrooms are more rarely seen on levels without small rooms, but they can use their acid to form a room. However, fleshrooms are not found in outdoor levels or levels with no walls.


Unlike most entities, fleshrooms will only eat intelligent creatures, such as wanderers and facelings. This has led to some confusion around what fleshrooms actually want from these creatures. Although it was originally assumed that fleshrooms merely wanted to consume these creatures, their hunting habits make some people believe that they instead consume thoughts. Fleshrooms usually target insane wanderers, by making them believe there is another wanderer in the room they are hiding in. They do this by breathing heavily and occasionally making noises that sound like talking. Although a sane wanderer would easily be able to tell that this is a trap, insane wanderers are typically not able to. Upon entering the room, the fleshroom immediately pulls its wanderer towards the centre of it by releasing a gas that induces hallucinations, however, they are only able to do this for so long. After a few seconds, tiny tentacles hold the wanderer's feet in place, and the fleshroom release a gas to relax them. Once the wanderer is restored to sanity after a few hours, the fleshroom will attempt to converse with them. Exactly what fleshrooms like to hear from wanderers varies wildly, but they generally do not like to talk about The Backrooms, and are easily angered. If the fleshrooms like a wanderer's character, they will be let free. However, if the fleshroom does not like the wanderer's character, they will begin to close in on the wanderer. The fleshroom will then stick out other small tentacles. While the tentacles that are used to hold down the wanderer's feet are harmless, these tentacles are covered with cnidocytes, and are likely extremely painful to touch, as wanderers caught by them will usually scream. This scream has been described by some as “the most terrifying scream ever made by a wanderer”. These tentacles also release venom that is able to dissolve wanderers, which the fleshrooms then absorb.


As fleshrooms are Cnidarians, they possess cnidocytes, tentacles, and are able to sting. Their tentacles are very small, almost microscopic, much like jellyfish tentacles. Similar to jellyfish, fleshrooms have 20 digestive pouches, with five on each wall, a few centimetres beneath their skin where they break down food. This food is then delivered to all of their cells via a circulatory system. Although no cnidarians have a circulatory system, this is possible, as fleshrooms likely developed it via horizontal gene transfer. Interestingly, the digestive pouches of fleshrooms do not excrete materials they cannot break down, they instead use cilia on the surface of the fleshroom to integrate it into the fleshroom, making it larger. This is why many fleshrooms have bones on them. Besides their digestive pouches and circulatory system, fleshrooms are entirely made of muscle cells, and they contain no keratin, so it is likely painful for anything to touch them. However, it is not believed that fleshrooms have pain receptors. Despite being very intelligent and able to talk, fleshrooms have no brain. They instead use nerve impulses as well as information stored all around the nerve cells in their body to talk. The mouth on the bottom of the fleshrooms is what they use to talk. While fleshrooms do make loud breathing noises, they have no lungs, and breathe by diffusing oxygen into their circulatory system. They artificially create airflow in order to get more oxygen. This is one of the most specific methods of detecting fleshrooms, as most levels do not have wind naturally, and so any feeling of “wind” is most likely created by a fleshroom.


Fleshrooms generally reproduce by selfing, creating small spores which can float in the air. These spores are attracted to small rooms, and, upon reaching these small rooms, form polyps and begin to consume bacteria. They initially create a thin layer of cells all around the room, and then begin producing acids to corrode it. As young fleshrooms are vulnerable and do not have much to eat, their metabolism is also very slow. It can take fleshrooms hundreds of years to reach adulthood, and most fleshrooms die before adulthood is reached. In their life, fleshrooms produce hundreds of spores, but only around 3 will become adult fleshrooms. Fleshrooms usually die to bacterial infection, as they have a very weak immune system and have cells that are a good breeding ground for bacteria.
