Item #: SCP-4872
Anomaly Class: Safe
Special Containment Procedures: SCP-4872 is to be kept in a room with concrete walls at all times. These walls need to be crafted as part of the floor, as well as a trapdoor as they seem to be the only type of door that is SCP-4872 proof. SCP-4872 made aware of how her containment cell was built. If this isn't possible, SCP-4872 must believe that the room is constructed this way. SCP-4872 must SCP-4872 doesn't need food, water, or any other utilities. A camera is to be kept on her at all times, and should anything unusual occur, the room is to be filled with [REDACTED].
Description: SCP-4872 has the appearance of a girl at around 12 years of age. SCP-4872 has brown hair and eyes, and appears to be caucasian. It's impossible to tell what SCP-4872's age truly is, or if aging is even something that SCP-4872 is possible of. SCP-4872 wears a blue shirt and some beige shorts. Her clothing never changes, even when new outfits are tired on. Despite using precise equipment, we are unable to pick up anything that would indicate that she is present, in the exception of cameras and our own eyes. It should be noted that despite being able to go through anything physical, much like a ghost might be imagined to, she is unable to go through the ground or anything that she believes to be the ground.
Acquisition: SCP-4872 was discovered when a phone call was made to the local police in [REDACTED]. Some kind of 'organization' had apparently found and tried to keep SCP-4872 in containment, but had apparently left the door unlocked. When SCP investigators had reached the base of the organization however, all they found was a residential house. Inside there was a room with a sign that read "Subject 001" hanging in the front. The room was pink in color, as well as the carpet and bed sheets. There were many toys typical of girls inside, such as dolls, stuffed animals, and a cellphone. None of these objects seemed to have been interacted with and had a good deal of dust on them. The organization, whose sole members were a married couple were terminated along with the house in a fire.
Addendum 4872-01: Interview log
Dr.[REDACTED]: Good afternoon, SCP-4872
SCP-4872: G-good afternoon? Will I be able to go back home soon?
Dr.[REDACTED]: I'm afraid that's not going to be possible.
Here, SCP-4872 seems to get visibly distressed.
SCP-4872: Why not? I'll stay in my room this time I promise! Please, I just want to go back home!
Dr.[REDACTED]: You can think of this as your new home. Now focus, do you know why you can phase through everything?
After some more prodding, SCP-4872 gave an answer
SCP-4872: I've always been like this alright! Now let me go back home! My parents might have gave me a weird name but they were all I had!
