Object Identification: SCP-6856
Object Class: Euclid
Special Containment Procedures: SCP-6856 is to be kept in a 10x10x10 room decorated in the fashion of a child's room. The room is to be furbished with a twin sized bed, a bean bag chair, a television with DVDs, and a box filled with toys and crayons. The room is to be daily maintained by the maid assigned to SCP-6856.
The room must be insulated in 2ft of osmium. Also, there must be no doors in its cell. When someone enters the cell of SCP-6856, they must enter a doorless hallway, then enter his cell by means of opening wall after the wall behind them closes. SCP-6856 must must be treated kindly and kept in a nice environment.
Object Description: SCP-6856 is a small humanoid creature weighing roughly 40 lbs. and standing at 2ft. Scans of SCP-6856 show that it is almost invincible and adapted for the harshest of environments. Scientists have hypothesized that it is equipped to survive the center of the sun.
On June 13, ████, SCP-6856 was given a CT scan. The scan revealed that SCP-6856 is missing a few vital organs, such as the lungs and the kidneys. SCP-6856 also has a few extra copies of organs. SCP-6856 has 3 hearts, 2 brains, and a few organs never seen in any other creatures. It also has a liver-kidney hybrid that cleans out foreign substances and releases a compound that neutralizes all toxins. Also, its immune system consists of a singular organ that releases some of the most powerful antibodies that easily kills any known disease. SCP-6856 also has all of the reproductive organs necessary to perform asexual reproduction.
SCP-6856 has the ability to teleport itself and objects using doorways as two-way portals. This is the reason that it must not be allowed to access any doors. It also has the ability to unlock any door, no matter how it is locked. It has been known to teleport people that anger or frighten it. Mr. █████████, a victim of SCP-6856, claimed to have been teleported into a different dimension. He reported being in a large mansion like room that had multiple hallways. He said that a few of them looked infinitely long, with doors along both sides. Look at the interview notes for more details.
SCP-6856 has the temperament of a small child. It is easily entertained but can quickly become frustrated. It must be treated with kindness and kept in a good environment. Scientists are afraid that it will adapt to its captivity and believe the best way to prevent this is by keeping it happy.
SCP-6856 was discovered in the town of ███████, Wyoming. The residents of ██████ reported strange phenomenons involving the doors. Mrs. ███████████ claimed that she walked out of her house only to walk into the bakery on the other side of town. When the foundation arrived, it found SCP-6856 hiding in the █████ residence. They quickly learned that catching it would be next to impossible. They made a doorway that disrupted its powers using █████ energy. They then chased it through the doorway and, when it tried to escape, it was teleported to the cell designed for it. Ever since then, it has become immune to █████ energy and developed the ability to unlock doors.
Interview notes:
Subject name: Mr. ████████
Interviewer: Dr. ██████
Reason for interview: Subject had an encounter with SCP-6856
Interviewer: Please state your name and place of residence.
Subject: My name is █████████ and I live in ██████, Wyoming.
Interviewer: Please tell me what happened.
Subject: Well… I was going with my wife to the bakery, but when she walked through the door she disappeared. I stood there dumbstruck for a minute when I heard it.
Interviewer: What was it?
Subject: That thing.
Interviewer: What noise did it make?
Subject: A kind of scurrying noise. When it crawled out of the kitchen, it looked at me cautiously. I slowly backed away from the hideous thing towards the doorway, but, when I walked through, the scenery changed. I was inside a mansion like place. I looked down one of the hallways to see that it was impossibly long
