Item #: SCP-XXXX

Object Class: THAUMIEL THAUMIEL THAUMIEL Keter

Special Containment Procedures: SCP-XXXX is contained in a 4x4 airtight room with a 5-meter inner wall and a 1-meter outer wall on every side, with a 2-meter space between them. Doing so will make SCP-XXXX effectively self-containing. When a breach occurs, MTF Delta-12 (Demolishers) are to be dispatched and contain SCP-XXXX at all cost.

Description: SCP-XXXX is an anomaly resembling a screaming humanoid creature, its body absent with the exception of its head and its 2 'arms' present when idle, seemingly manifesting inside concrete walls and can only phase through them. Any other material/walls less than 5 centimeters will prevent it from phasing. SCP-XXXX also has the ability to change shape and form.

Discovery:

SCP-XXXX was initially discovered by MTF Delta-12 (Demolishers) when an art museum in ███████ reported missing person cases, where SCP-XXXX disguised as part of the artwork. A squad was sent to investigate the situation. the anomaly was contained 2 hours later IM TRAPPED HELP ME PLEASE
