SCP-XXXX
Object Class: Safe
Containment Procedures:
SCP-XXXX is to be kept in a large room, with one half being a park setting and the other half being a house setting. 3 Meals are to be put in the kitchen part of the house setting every day. After the third meal, ice cream is to be put on the table in the kitchen in a small container. Every meal is to be thrown away if any bits are left, and ice cream is to be kept in freezer until SCP-XXXX is done with the third meal. If SCP-XXXX is saying it's hungry in between 2 meals, a snack food is to be put on the table in the kitchen. Food should be planned and stocked up 1 week in advance in order to ensure food is always available.
Park layout and fine details about the play things are to be changed when SCP-XXXX has started to show signs of being bored of current park. Changed details include but are not limited to: Slide length, spiral/straight slide, inclosed/open slide, slide color, swing color, monkey bar length, monkey bar color, layout of jungle gym, patterns of jungle gym walls, floors, and/or ceilings, and jungle gym color. Signs of SCP-XXXX being bored of the park are: Not playing in park for very long if at all, a bored face when playing in park, and/or directly telling foundation personnel that it's bored of the park. If SCP-XXXX is unhappy someone should be sent in to play with SCP-XXXX until it sleeps, at which point changes can be made to the park. Whoever is sent in doesn't matter, it can be a D-Class, Scientist, or even an MTF if one of them wants to go in on break.
Description:
SCP-XXXX is a 9 year old girl, with a height of 4.1 feet, and weight of 63 pounds, with red, short hair, and green eyes. SCP-XXXX appears to be capable of perfect speech, however, it does not know many long words with 6 or more characters, and appears to just pronounce them how it hears other say the words.
SCP-XXXX has unbreakable and unmovable skin. It is unknown if any other part of SCP-XXXX is unbreakable and unmovable, with the only force capable of making SCP-XXXX's skin move was SCP-XXXX punching its own arm willingly.
Due to the nature of SCP-XXXX's unmovable skin, it can break anything with 1 punch, headbutt, ram, kick, or any other form of attack. Testing has shown no material capable of withstanding an attack from SCP-XXXX, however, the durability of the material does determine how much speed is lost upon breaking through.
SCP-XXXX is extremely cooperative with foundation personnel, and is even extremely cooperative with any D-Class personnel.
Recovery Log
SCP-XXXX was found wandering in a desert. SCP-XXXX claimed to have not eaten or drank anything in around 5 months, saying it had seen at least 148 nights and days go by. SCP-XXXX was instantly taken by the foundation to explore why SCP-XXXX didnt die of thirst or starvation.
Addendum XXXX-1:
Containment test 1 log: SCP-XXXX put in blank, empty room. Room is sealed off. SCP-XXXX told they will be released in a few minutes. SCP-XXXX waits patiently. Tranquilizing gas is sent into the room. After 5 minutes SCP-XXXX still shows no sign of being affected by the gas. SCP-XXXX requests to be let out. Gas stops flowing. SCP-XXXX is let out.
Researchers are still baffled at how SCP-XXXX didnt get affected by the gas.
Containment test 1 has failed, new containment procedures are to be tested and used if they work.
Addendum XXXX-2:
SCP-XXXX appears to have "loved ones" which it shows more affection to. Testing has indicated that SCP-XXXX wants to protect its "loved ones", and will attack any who attack its "loved ones". If told to not attack those attacking its "loved ones", it will do so, but will show large amounts of grief when its "loved ones" are attacked. It appears that "loved ones" are chosen based on amount of time spent with SCP-XXXX. D-82931 was sent in to play with SCP-XXXX once, no sign of being a "loved one". Sent in to play a second time, slight signs of being a "loved one". Upon being sent in to play a third time, tests showed that D-82931 was a "loved one" by SCP-XXXX.
Addendum XXXX-3:
Containment test 2 log: SCP-XXXX brought in room with Dr [REDACTED]. Dr [REDACTED] had a gun with him. Dr [REDACTED] quickly shot the left and right eyes of SCP-XXXX, in an attempt to blind it. The bullets bounce off of SCP-XXXX's eyes and fall to the floor. SCP-XXXX stares at Dr [REDACTED], exclaiming "That hurt!". SCP-XXXX is let out of room. Dr [REDACTED] leaves and gives personnel gun.
Containment test 2 has failed, new containment procedures are to be tested and used if they work.
Addendum XXXX-4
Per request of Dr [REDACTED], SCP-XXXX has been interviewed by Dr [REDACTED]. Interview audio log below:
Dr: So, how or when did you get your strange, unbreakable skin?
SCP-XXXX: Well… I don't know. Last I rem-amber, the first time I saw my super powers… *pauses*
Dr: Continue.
SCP-XXXX: I was at the park. Some bullies came up to me, they said, ummm… "stupid red head" or some-sing. One of them tried to punch me, but his hand made a crunch and he screamed.
Dr: Where did he punch you?
SCP-XXXX: In the… Body… The ummm… Bod-
Dr: The chest?
SCP-XXXX: Yeah, thats what its called.
*Sounds of Dr [REDACTED] writing down notes*
Dr: When do you think you first got your "super powers"?
SCP-XXXX: I… Don't know. Maybe when I was first born?
*Sounds of Dr [REDACTED] turning a page and writing down notes*
*Recording ends*
