Item #: SCP-XXXX

Object Class: Keter (I think? It seems complicated enough…?)

Special Containment Procedures: Foundation webcrawlers are to monitor all popular social media and news outlets for mentions of ‘dancing plagues’, ‘weird dances’ or any other term that may imply SCP-XXXX infection. A visual recording of a D-Class personnel member performing the first five minutes of SCP-XXXX is to be kept on a secure Foundation server.

Update ██/██/20██: A copy of SCP-XXXX-2 is to be kept on a secure Foundation server.

Foundation agents are to periodically discourage civilians from performing the individual steps of SCP-XXXX by demeaning the quality of the moves at dance clubs and on social media.

In the case an SCP-XXXX infection is determined, MTF Eta-10 ("See No Evil") is to be deployed to humanely terminate any instances of SCP-XXXX-1.

Under no circumstances is an instance of SCP-XXXX-1 to be allowed to continue dancing for more than 168 hours (1 week), for fear of causing local reality failure.

Description: SCP-XXXX is a set of motions superficially resembling a dance that are separately generally non-anomalous begin non-anomalous, but rapidly become anomalous.

Any human being who views another human being perform any part of SCP-XXXX for at least 10 consecutive seconds (hereafter designated as SCP-XXXX-1) is infected by SCP-XXXX. Newly formed instances of SCP-XXXX-1 will observe the SCP-XXXX-1 instance that infected them for an additional ten seconds before also performing SCP-XXXX from the start, regardless of which part of SCP-XXXX the observed SCP-XXXX-1 instance was performing. Instances of SCP-XXXX-1 appear to know the entirety of SCP-XXXX and are generally able to perform it, despite lack of former interaction. SCP-XXXX is always identical, regardless of the SCP-XXXX-1 instance that performs it.

Instances of SCP-XXXX-1 have increased flexibility, and their joints appear to be able to bend at least twice as far as compared to their ‘base angle’ when compared to the SCP-XXXX-1 instance’s former state. Some SCP-XXXX-1 instances gain more flexibility than others, seemingly at random. It is currently unknown how SCP-XXXX grants this increased flexibility to SCP-XXXX-1.

Instances of SCP-XXXX-1 are unresponsive to external stimuli, and do not require nutrition or liquid intake; Adequate nutrients and water appear to spontaneously manifest inside instances of SCP-XXXX-1. The mechanism by which this occurs is unknown. In addition, SCP-XXXX-1 instances do not require rest, and no SCP-XXXX-1 instances so far have attempted to stop performing SCP-XXXX for any reason.

If an instance of SCP-XXXX-1 fails to perform any part of SCP-XXXX, whether by external physical manipulation or because their limbs are not adequately flexible, the SCP-XXXX-1 instance will suffer from abrupt heart failure approximately 1 second after the ‘failure’, universally leading to death. Application of amnestics replicates this effect; The SCP-XXXX-1 instance will stop performing SCP-XXXX for approximately 1 second before expiring. Autopsy has revealed SCP-XXXX-1 corpses to be non-anomalous, although the increased joint flexibility remains. Additionally, large amounts of endorphin1 are present in the brains of SCP-XXXX-1 corpses.

Observation of SCP-XXXX-1 instances without being infected by SCP-XXXX is possible by viewing photographs or videos less than 10 seconds in length taken of SCP-XXXX-1. Personnel universally describe SCP-XXXX-1 instances as appearing non-anomalous, and their expression to look ‘blissful’ or ‘relaxed’.

SCP-XXXX appears to have no end, as it has been recorded to continue for at least 2██ hours.

Addendum XXXX-01: On ██/██/20██, Foundation webcrawlers detected a user account on the popular video sharing website ‘YouTube’ of which the access history did not trace back to a valid IP address2, called ‘CHH’. The user account contained only a single video 14 minutes and 37 seconds in length, later classified as SCP-XXXX-2, called ‘The CHH presents: The Dance of Glee!’. Due to safety concerns, the video was initially viewed only in 5-second intervals by a D-Class personnel member. After it was determined the video contained SCP-XXXX, the video was transcribed by viewing it in separate, non-chronological 5-second intervals.

A full transcript of the video has been placed below.

PoI-XXXX’s voice, as well as the physical profiles of PoI-XXXX and SCP-XXXX-1-A through SCP-XXXX-1-F, do not match with any profiles in the Foundation’s database.

The video was copied to a secure Foundation server and deleted without issue. The user account associated was not able to be deleted, as it is not present in YouTube’s user database.

Notably, SCP-XXXX-2 displays the only known occurrence of an individual starting SCP-XXXX and stopping without expiring. Careful reproduction of the video’s circumstances using D-Class Personnel did not succeed in reproducing this occurrence.

Addendum XXXX-2

On ██/██/20██, approximately 24 hours after deletion of SCP-XXXX-2, a letter was received at Site-██. A transcript of the letter is available below.

Correspondence with and espionage of several GoIs has revealed that all known GoIs with a centralised command structure have received an identical letter.

Since the address given in the letter does not appear to exist, no attempt to respond has been made.
