Per 
Containment:
Instances of SCP-XXX are to be contained within (coffin size?) padded sound proof cells with 24/7 video surveillance. Testing with multiple instances of SCP-XXX is to be done only with authorization of a level 4 researcher or above. Testing with instances of SCP-XXX is to be done in a sound proof testing chamber with no audio recording devices. Only D-Class personnel are to be within the chamber during testing.
Any instances of SCP-XXX found outside of containment should be neutralized following the procedure outlined in Document XXX and the remains disposed of using standard biological waste protocols.
Description:
SCP-XXX is the classification given to anomalously animated human skeletons which all exhibit similar properties. SCP-XXX instances are anatomically correct when standing at approximately 5'10'', however, they can stretch or compress various bones in their bodies to
different lengths and seem to do so at random. The tallest recorded height for an instance was 9'2'' with the shortest being 1'7''.
When not observed by any human, SCP-XXX instances will rattle and bang their bones against various objects, creating sounds described by subjects as, "unnerving". If directly observed, or at the risk of being observed by one or more human subjects, SCP-XXX will collapse into a pile of seemingly-inanimate bones which can be seperated with no noticable effect. The skull of an SCP-XXX instance will retain all anomolous properties with other bones lacking in animation.
The foundation currently has || instances of SCP-XXX in containment.
Experiment XK: Human subject
Human subject does x
Human subject does y
Human subject restrained and blindfolded + noise cancelling headphones
Experiment XJ: Give the Skeleton another regular skeleton
Play recording to human subject
(cognitohazard: believes bones are trying to escape, no sign of this being the case. After termination becomes SCP instance now SCP-XXX-i, unknown how many might be affected)
Experiment XI: Introduce two Skeletons
Two Skeletons + Human
Doc XJ: Where instances were found
YouTube video of spooky music in a graveyard, determined to be multiple SCP instances, animated entire cemetary, video taken down but not befor XXXXXX views. Class 0 amnesiacs administered w monitoring for further manifestations of SCP
