Man-eating rooms

A Man-eating room is a large magical predatory animal native to Helt.

Appearance
Man eating-rooms have a body that is mostly composed of a white mineral-like substance. Their size can range from anywhere between a closet to a small ballroom. They have no limbs, and can only move by sliding on a gelatenous secretion, much like a snail.

Man-eating rooms have powerful shapeshifting powers. They can make themselves appear like actual, fully furnished rooms.

Behaviour
Man-eating rooms are produced asexually through magic by Satan, and a few high-ranking Devils. Upon creation, they will instinctively seek out a hollow space and settle themselves into it.

Man-eating rooms prey mostly on humans and other sentient species by pretending to be rooms, and waiting for humans to enter. They are highly intelligent, and have been known to mimic the speech of their prey species. Upon entry, the man-eating room will seal the door that its prey used to enter, drop the false appearance it created, and devour everything else inside.

Man-eating rooms on Earth
Due to their enormous size, and very slow movement, they can hardly ever settle on a planet inhabited by sentient species, as anyone even remotely knowledgeable in Heltish creatures will recognize them, and alert authorities.

There have been cases of lone man-eating rooms deployed in key locations by Satan. These attacks happen very seldom, but often times cause large casualities. Well-hidden man-eating rooms can go unnoticed for years, as they usually don't leave survivors.

A living man-eating room is on display in the Zoological University of America in New York, as well as several specimen found in the OmegaZoo in Andromeda Galaxy.

Indiana Stark has tamed several man-eating rooms, some of which can even perform parlor tricks.

Trivia

 * The largest of man-eating rooms are known to have grown to the size of small warehouses.
 * Satan traded a man-eating room to the Zoological University of America in exchange for one of the researchers commiting self-sarcifice. The specimens in OmegaZoo were gathered by Heltish poachers.
