Item #: SCP-XXXX
Object Class: -Euclid- Keter
Special Containment Procedures:
SCP-XXXX is to be kept in an approximatly 5m X 5m X 5m square containment cell with only a bed to occupy it. The cell is to be cleaned once a week and the subject is to be monitered by ifrared cameras at all times. During the cleaning procedures, the subject must be transfered to a designated holding cell of the same size as it's original cell. Each of the holding areas is to be guarded by two facility guards, each equipped with a special sedative obtained from Dr. ████. Once every other week, the subject is to be sedated and have it's mouth re-sewn shut after acquiring saliva to prevent the actual threat. -Small- Large doses of sedatives are to be disspenced into the cell to keep the subject blank minded.
In the case that the subject begins to drool, it is to be reported immediatley and to have the facility guards sedate and re-sew the mouth. In the event of a containment breach, the entire site is to be locked down and all scientist of 02 level of clearence is to be transfered to a room of one sided glass. Facility guards are advised to stay out of sight and to sedate SCP-XXXX as soon as possible.
Description:
SCP XXXX is a humanoid figure resembling a young caucasian male roughly 25 years in age. The subject is in perfect condition and background is unknown. Dna tests are inconclusive. The subject is approximatly 2 meters in hight. The mouth has been sewn shut to prevent SCP XXXX-1 from rampaging. The subject is extremlly violent, but won't move while it's mouth is shut. The subject themselves is about as dangerous as an unarmed human can be. It can survive without food or drink, and is indistructable by conventional means, but isn't much of a threat itself. It's mouth can stretch to the same size as the subject, and can eat anything. We believe pocket dimensions are in play. -Further research required- This has been confirmed.
SCP XXXX-1 is comprised of the entities tounge which is unusually long by human standards. It is seemingly infinite. The Dna samples collected from the saliva has proved difficult to obtain, as it's acidic properties are far more corrosive than any acid currently known. The acid-like substance has been know to melt everything it comes into contact, however it' harmless after 15 minutes away from the host. SCP XXXX-1 seemingly has a mind of it's own, tending to lash out at anyone that is within eye sight of the subject.
After swallowing a victim, it under goes an adaptation of sorts and get's more and more difficult to recontain it. Regular sedatives will have no effect and the special narcotic will be the only one that would work. Assumably after consuming approximatly ██ amount of people, It will become impossible to contain as the special narcotic will cease to affect the subject, becoming invincible. It is not to be allowed to escape, as it can cause an end of the world scenario.
