Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX, commonly referred to as "magic-monkey" by site staff, is to be contained in a 0.4x0.4x0.4 meter lead box, that must be sealed every-night between the hours of 7 pm (GMT) and 7 am (GMT); as of now, it is unknown why the object's anomalous properties manifest between these hours or why lead is the only material that can suppress its effects on the human body. The box must be airtight to prevent unwanted de-evolution.
Description: SCP-XXXX appears to be a small, stuffed, toy monkey made by the toy company, Keel Toys, during the early 2000's. Despite its rather unspectacular exterior, its interior, physically, should not exist. Internally, it possesses a fully functional, yet partially-inactive, internal system, not dissimilar to that of an African Vervet; for example, its respiratory system does not function however its digestive system appears to work as it should. At this time, site staff have deemed it "a waste of resources" to investigate how it came to possess these organs due to the other, more hazardous, SCPs at the facility that pose more of a threat to people and humanity as a whole. Furthermore, due to the SCP's small arms and legs, its muscles are unable to function properly.
SCP-XXXX was first discovered in the city of ██████ on the ██/██/20██ after reports of disappearances and primate attacks, by species not native to that area, began to show up. The primates were extremely violent towards people and the foundation determined the source of the primates was SCP-XXXX, which was then transported to site-██.
SCP-XXXX's anomalous properties begin to manifest at approximately 7 pm and, from this time, any person who comes within a 5-meter radius of SCP-XXXX will begin to de-evolve and transform into a random species of primate, who will be deemed as SCP-XXXX-1. Once a subject enters within this area, nothing can be done to halt the process except termination of SCP-XXXX-1. Once the transformation process begins, the subject will begin to transform, starting at the feet, ending at the head. The subject will be forced to remain conscious throughout the entire 5-hour process and feel everything. The transformation, as described by various subjects feels like burning and causes most instances of SCP-XXXX-1 to scream for, almost, the entire process.
Once the transformation process is complete, SCP-XXXX-1 will stop screaming and proceed to attack the nearest human it can find by ripping out their windpipe; SCP-XXXX-1 will then attempt to consume the victim and regurgitate any undigestible materials. This can range from a preventable event to a security threat as SCP-XXXX-1 instances have been known to range from small squirrel monkeys to giant gorillas; if SCP-XXXX-1 becomes anything too powerful, such as a gorilla, it is to be terminated immediately to prevent damage to the surrounding area and personnel. After 7 pm SCP-XXXX will lose all of its anomalous properties and is then safe to be handled by site staff. It is unknown whether or not SCP-XXXX can transform SCP-XXXX-1 into an SCP-1000; for this reason, all tests must be authorized by staff who have level 4 clearance or higher.
Addendum XXXX-A: The following is an interview conducted 2.6 hours into the transformation process after a D-class was exposed to SCP-XXXX at approximately 1:43 am on the ██/██/20██.
Interviewer - DR. █████████
Interviewee - D-6495 / SCP-XXXX-1DR. █████████: Hello D-6495, my name is DR. █████████ and I am here to ask you a few questions
D-6495: (screaming) Go f**k yourself! (screaming) What have you done to me?!
DR. █████████: To be totally honest with you, we don't know. So please, enlighten us on how you are feeling.
D-6495: (screaming) My legs! I can't feel my legs! What is happening to me? (screaming)
DR. █████████: You say this, however, you possess the ability to move them and you obviously can feel them due to your constant-(Screams), that.
D-6495: It's not like that…ah…all of me hurts (screams)
DR. █████████: Can you please be more specific?
D-6495:(Screams)
DR. █████████: D-6495………..D-6495!
<End Log>
After this exchange D-6495 refused to talk and was terminated as a result. No further tests are planned.
