Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures:
SCP-XXXX is to be kept in a 300x300 mm cage within a 5x5 meter containment room. The cage must contain a food and water dish and a hamster wheel. SCP-XXXX must be fed at least twice a day. SCP-XXXX's cage is to be cleaned on a weekly basis and requires two personnel: one to clean the cage and another to monitor SCP-XXXX as it is given free reign inside the 5x5 meter room. SCP-XXXX must be observed by at least one researcher remotely (via security camera) at any given time while inside its cage.
SCP-XXXX may not, under any circumstances, leave its containment room. In the event that SCP-XXXX is angered, containment lockdown will be initiated wherein the containment room will be locked and secured during the duration of SCP-XXXX's anger. All staff within the containment room are required to leave immediately before lockdown is put into place. All personnel who are unable to leave the room before lockdown is initiated are to be deemed "trapped" and at the mercy of SCP-XXXX. In the unlikely event that SCP-XXXX breaks containment, the entirety of Site █ shall go into lockdown until either SCP-XXXX is re-contained or returns to its original form.
Description:
SCP-XXXX appears to be a Pygmy African Hedgehog roughly 4 cm in size. Extensive tests have shown that despite having a pulse, lungs and a digestive tract, SCP-XXXX does not require food, water, or oxygen to survive.
SCP-XXXX utilizes telepathy to converse with anyone within its range of sight. Its telepathic message often presents itself as a voice in the mind and is often described by researchers as sounding "miniaturized" in nature and similar to Alvin from "Alvin and the Chipmunks". SCP-XXXX usually uses its telepathic abilities to make demands towards the staff, often for certain liberties such as time outside its cage, food, and its freedom.
SCP-XXXX is malevolent in nature and will often threaten non-compliant researchers with "eternal torment" and the deaths of their respective friends and families. SCP-XXXX will also attempt to lie its way into getting what it wants, going so far as to utilizing its appearance to charm researchers. To date, SCP-XXXX has yet to successfully sway researchers into giving it anything other than belly rubs and treats.
Should SCP-XXXX become excessively angered, SCP-XXXX will increase its size and mass to fill the space it is in. The size of SCP-XXXX, when angered, entirely depends on the size of the room it is placed in. The increased size of SCP-XXXX will last as long as either SCP-XXXX's anger or until SCP-XXXX finds a bigger space to expand. Due to both the malevolent nature of SCP-XXXX and its potential to fill up any space, access to outside Site █ is restricted.
Recovery:
SCP-XXXX came into Foundation custody after the Foundation received a report of an anomalous hedgehog causing property damage in █████, North Carolina. SCP-XXXX had been discovered by a family of three, lying on their doorstep in a shoebox with a note attached to it. The family adopted SCP-XXXX and approximately three days later, the family's house collapsed in on itself. First responders found the parents mildly injured, their daughter seriously injured, and SCP-XXXX, in its normal form, crawling away from the scene. The daughter, having suffered from multiple lacerations and impalements, was taken to the nearby hospital where she was eventually stabilized. The cause of the house's collapse and the daughter's injuries were never discovered by first responders. Agent █████, who had been placed in the local police department, interviewed the family and reported his findings to the Foundation. SCP-XXXX was moved to Site █ shortly afterward.
Addendum:
Incident XXXX/1A:
On October 12, █████, two weeks after containment, assistant researcher Dr. Michaels was interacting with SCP-XXXX during its weekly cage cleaning when a body-less voice, later determined to have been SCP-XXXX, asking for food. The request was heard by both Dr. Michaels and Dr. Jim as well as head researcher Dr. █████, who had been monitoring the cleaning duty from the observation room. According to all three men, the voice didn't originate from one direction and appeared to have come from every direction.
Security Footage of Incident XXXX/1A
Footage depicts Dr. Jim cleaning SCP-XXXX's cage while Dr. Michaels is holding SCP-XXXX and giving it a tummy rub.
Any verbal or mental contact initiated by SCP-XXXX is to be reported to head researcher Dr. █████. Any requests made by SCP-XXXX need to be approved by head researcher Dr. ████.
Further research on SCP-XXXX’s origins is being conducted.
