Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX is to be stored in a standard containment cell with white walls, and the addition of lights on every interior wall that emit wavelengths of 1e-9.
The outside of the cell must be surrounded by infra-red light. The entrance needs to have an infra-red light which doesn’t shine into the cell, but covers the entrance. No infra-red or shorter wavelength of light is to enter the cell.
Every two (2) months, SCP-XXXX requires a live animal, preferably an adult canine, weighing approximately twenty (20) kilograms. After entering the cell, the animal is designated as SCP-XXXX-2. SCP-XXXX-2 is redesignated as SCP-XXXX-1 after the previous SCP-XXXX-1 is incinerated. The animal must be placed into the cell after SCP-XXXX-1 is removed.
The cell should only be opened in-between 1100 and 1300.
The X-ray lights are to be switched off for 2220 seconds at 0100 daily.
The infra-red lights are to remain on at all times.
When opening the cell, the D class assigned to SCP-XXXX must chain themselves to a hardpoint. A loop and pole instrument must be used to retrieve SCP-XXXX-1. The length of the chain must be short enough so that the chained D class can’t pass the infra-red light at the entrance of the cell, and the chain must have a tensile strength of at least 400kg. The D class may be unchained after SCP-XXXX-1 is out of the containment cell, and the containment cell is closed. SCP-XXXX-1 must be thrown into a sealed furnace, along with the loop and pole, and incinerated at seven hundred (700) celsius for no less than three (3) hours.
Human blood with high vitamin C levels must be supplied to the cell through a water bowl via a tube in the bottom. It should be kept at thirty-seven (37) degrees celsius and mixed with an anticoagulant.
SCP-XXXX is not known to interfere with the animal replacement process. If any incident occurs, close the containment cell and report to a level two (2) staff member.
Any D class interacting with the SCP-XXXX, SCP-XXXX-1 or SCP-XXXX-2 are to be given no information about [DATA EXPUNGED] or the animals involved;
If a D class appears agitated, the D class may be be told: “They’re just dogs that keep SCP-XXXX company, and hence, passive. They’re completely harmless.” If SCP-XXXX-2 witnesses SCP-XXXX-1 break their disguise, both SCP-XXXX-1 and SCP-XXXX-2 must both be shot at least 5 times, with any type of gun, and then incinerated. The D class is to be given class A amnetics [DATA EXPUNGED].
Description:
SCP-XXXX is 30 centimetres tall, weighs approximately 57 kilograms, and usually keeps itself as a bi-pedal humanoid form but can change its bone structure and organ locations within its skin. Its skin is covered with fur which is constantly moving around its body. The fur can change colours, but generally opts for the colour of its environment. The fur can increase in length, up to 13 centimetres, but generally keeps it at an average of 3 centimetres.
X-ray lights are effective at countering its camouflage, as the wavelengths interfere with its cognitive function. While under x-rays, its fur colour reverts back to black, and ceases movement around its body. SCP-XXXX enters a placid state while under x-rays.
SCP-XXXX requires another animal every two months to act as an intermediary in its feeding process. When a new canine enters the cell it is redesignated as SCP-XXXX-1. SCP-XXXX-1 never notices the presence of SCP-XXXX, even when it is looking directly in its direction.
When the X-ray lights are turned off at 0100, SCP-XXXX envelops SCP-XXXX-1 with its entire body. It becomes a sphere of shifting fur, the approximate size of the two subjects combined.
Its stays like this for approximately twenty (20) minutes. Afterwards, SCP-XXXX retracts from SCP-XXXX-1.
SCP-XXXX-1 outwardly resembles its previous form in every way, and even responds to recorded audio commands from its previous owners (sit, stay, fetch).
Autopsy has revealed that SCP-XXXX-1 (previously a normal dog), now has two stomachs, a fleshy proboscis enclosed in its throat, no intestines, and bones that are porous and a hexagonal structure resembling a honeycomb, resulting in SCP-XXXX-1 weighing less.
At 0300, SCP-XXXX-1 is drawn to the water bowl filled with human blood. It unhinges its jaws and a siphon extends from its throat. It proceeds to drain the blood from the bowl.
22 hours later, at 0100, SCP-XXXX approaches SCP-XXXX-1 and makes a noise inaudible to the human ear, somewhere within the 80 kHz to 200 kHz range; SCP-XXXX-1 then extends its siphon from its throat and produces ball of crimson coloured mucus which is quickly consumed by SCP-XXXX.
[DATA EXPUNGED]. Infra-red light is therefore an effective containment measure.
Acquisition of SCP-XXXX:
SCP-XXXX was captured near a village called [REDACTED], Bulgaria, using its intermediary host animal as bait.
Initially, locals thought they were just getting sick; The victims would wake up light-headed and usually with a small incision, often unnoticed, around the ankle area. A maximum of two (2) people were ‘sick’ at the same time. This ‘sickness’ has been happening to this village since ███ ██████. A ritual had been created around it, where the villagers would place flower-chains made from Kazanlashka Roza (Kazanluk Rose of Bulgaria) around their animals necks as an attempt to transfer the illness. The villagers noted the animals didn’t flinch when prodded by the rose thorns.
It was observed that the disappearance of this "sickness" coincided with one or more of their animals disappearing within three months of contracting it"
After contracting the “sickness”, a villager decided to chain up his only animal, a medium sized canine, to make sure it wouldn’t escape without their sickness going with it. In the morning the animal was gone. A nearby safety camera footage revealed a translucent entity, SCP-XXXX, approaching the animal. SCP-XXXX is determined to have been making the signature inaudible feeding noise, only to receive no response from the animal - presumably because the animal hadn’t fed on its human host.
SCP-XXXX promptly freed the animal from its restraints by fracturing its skull and pushing it through its chained-collar. The animal seemed to have no discomfort during this ordeal.
Both the animal and SCP-XXXX escaped together.
The civilian believed their animal was stolen. After some investigation, local authorities found the safety camera footage, and promptly contacted the The SCP Foundation.
Upon the arrival of SCP agents, the civilian, along with anyone who viewed the footage, were promptly given class B amnetics - and all footage of the incident was destroyed.
Blood samples were taken from the civilian. No virus, bacteria, fungi, parasites or other types of pathogen were detected, only extremely low blood pressure and a vitamin C deficiency.
The next case of this reported “sickness” was made two weeks later, approximately 800 meteres away from the first report.
The animal in question was another canine; the host of the creature looking sickly and pale. The host was given class A amnetics, as two class E agents investigated the area behind the house, where the creature was subsiding.
Two D class approached the animal with extreme caution while attempting to capture it.
On approach, the creature realized it had been detected. Immediately, the canine stood up on two legs, lunged forward, attempting to pierce an agent with a bone protruding from its front-right leg. It was unable to pierce the agents kevlar vest, and was quickly dismissed with 5 rounds from a standard issue HK P46; however this didn’t dispatch the canine-creature entirely, and was promptly captured.
The canine-creature was chained up within an iron cylinder - sealed at one end, with a pressurized quick-release mechanism to trap SCP-XXXX on the other end.
At night time, SCP-XXXX was drawn to the canine-creature, and without a second thought, walked straight into the cylinder. The trap triggered, and proved effective at initial detainment. SCP-XXXX moved around in the cylinder quickly; [DATA EXPUNGED]. Agents attempted to view it with night-vision cameras with attached IR lights, however it began to get aggressive in its containment cylinder and attempted to break out. The IR lights were turned off, and it was quickly surmised that thermal-imaging, along with other forms of infra-red, are harmful to SCP-XXXX. Holes, dents, and deep scratches were made in the 5cm thick cast iron cylinder by SCP-XXXX while the infra-red lights were on, and SCP-XXXX quickly went placid after they were turned off.
The cylinder was then transported to site-██ where it was placed in a standard containment cell. At 0100, SCP-XXXX became more active and quickly broke out of its cell, however it was forced to retreat back into the cell after guards used infra-red lights to stop it.
The SCP-XXXX was transferred to another cell at 0900, which was then surrounded by infra-red lights. More tests were conducted with different wavelengths. The conclusion of these tests are that long wavelengths (infra red, microwave) make SCP-XXXX aggressive, while shorter ones have the opposite effect.
While X-rays were emitted at SCP-XXXX, the fur on its body stopped shifting around it and changed into a black colour SCP-XXXX then curled into a ball and became passive.
Addendum XXXX-01:
A follow up investigation revealed the discovery of a cave containing animal bones, mostly canine in nature, some petrified and many unidentifiable, dating as far back as 600AD. All bones were porous and had a similar hexagonal structure. The cave is located fourteen (14) kilometres from the nearest village, and had no continuing passages or chambers, and was summarily collapsed with explosives, sealed with cement, and covered up as an earthquake.
Within the last 50 years, similar discoveries of porous-hexagonal bones in other caves and cave systems around the world, including Mexico, Brazil, Australia, Argentina, Mongolia and Pakistan have been made.
A contingent of MTF Zeta-9 ("Mole Rats") has been deployed to investigate each of these cave sites.
Addendum XXXX-02:
It is recommended that any D class interacting with SCP-XXXX, SCP-XXXX-1 or SCP-XXXX-2 are given no information. If a D class believes SCP-XXXX-1 or SCP-XXXX-2 are still just animals, SCP-XXXX-1 and SCP-XXXX-2 maintain their disguise, even to the point of being shoved into a furnace; possibly this is to protect the true master of SCP-XXXX-1 and SCP-XXXX-2, which is now SCP-XXXX.
SCP-XXXX remains in a passive state as long as it has a food supply, otherwise, it just attempts to camouflage itself within the cell.
SCP-XXXX-1/2 don’t seem to realize what cameras are, and hence, maintain their disguise as whatever their previous forms were. When SCP-XXXX-1/2 thinks no one is watching, SCP-XXXX-1/2 goes into catalepsy, only leaving this state again when a human is nearby in order to continue its
