Special Containment Procedures: SCP-XXXX and related anomalies are to be kept in a standard Safe-class containment locker at a high security site (currently Site-███). Site-███ is to report intruders with ballet apparel or missing/artificial limbs with unusual characteristics to continental security command.
Description: SCP-XXXX is a small granite-shale composite rock. SCP-XXXX has no known physical anomalies, though Foundation physical anomaly tests have been waived.
SCP-XXXX's anomalous properties manifest under highly specific human interaction. The known conditions are:
- Contact with the head.
- Amputation above the knee in exactly one leg.
- Proficiency in playing a saxaphone.
- Wearing a pink tutu made of at least 90% cotton..
"Partial" activation events from subjects meeting some but not all activation conditions induce variable but minor changes in SCP-XXXX, such as glowing, heating, and shaking.
A "complete" activation event causes a spontaneous shift in the Higgs particles composing SCP-XXXX's into a true vacuum state, resulting in an immediate and currently irreversible VK-beta True Vacuum End of Universe scenario.. [the specifics of the reality ending scenario aren't important]
Discovery: On 24/05/1971, an adjacent local-sequence universe Alpha-1234 underwent an apparent spontaneous VK-End of Universe event. Using the final reported fail times of Alpha-1234 DEEPWELL sites, a Department of Extra-Universal Affairs postmortem triangulated the collapse to Panswick, England. Panswick was evacuated, and SCP-XXXX was eventually found after a thorough Brown-Scoffia sweep.

Subsequent investigation put the likely full activation scenario as a juvenile throwing SCP-XXXX at Linda Smith, targeted for mischief for her unusual attire and stature.
Update (18/11/1979): A cross database check with the Anomalous Geology Department found an anomalous item (formerly ITEM-3581) that "anomalously heated when breathed on by Doctor Arif while holding a pickaxe in his right hand". Further testing found additional conditions: self-identification as a Prussian citizen and a four-fingered right hand (Doctor Arif is missing his right fourth-digit). ITEM-3581 has been redesignated SCP-XXXX-1 and transferred to Site-███, though at a lower containment priority owing to current geopolitical trends.
Update (13/06/1985): Foundation assets have recovered two more potential SCP-XXXX instances. Research into identifying potential SCP-XXXX instances is underway (led by researchers Foo and Bar).
Update (13/02/1988): Researchers Foo and Bar have constructed a functioning detection machine prototype. SCP-XXXX-1 through SCP-XXXX-5 have a confirmed "Full activation" characteristics. Broad pebble sampling to determine the natural frequency of SCP-XXXX instances is underway.
Update (19/02/1988): Containment procedures fully revised, click to view. [Would be two separate pages]
Special Containment Procedures: MTF-Zeta-8 ("Sons of Barney Rubble" "Pebble Pluckers") has been established to Operation Groundbreaking and other SCP-XXXX tasks. MTF-Zeta-8 is responsible for Foundation compliance with Operation Groundbreaking and other SCP-XXXX related containment. MTF-Zeta-8 has broad discretion to enact cultural and social interventions, along with technological and Foundation policy interventions with O5 approval.
Research into space travel and colonization are underway and considered a top-level Protect priority. Evacuation procedures are to be implemented as soon as human civilization is no longer dependent on Earth's biosphere for survival. [I can drop the "Earth" thing if I don't want this part].
Description: SCP-XXXX is a phenomenon affecting all known pebbles on Earth.
Individual pebbles have a unique corresponding activation event requiring a form of highly specific human-interaction. While the chance of any individual pebble interaction is extremely unlikely, in some cases impossible in our current universe, the sheer quantity of human-pebble interactions poses an existential threat.
Pebbles may be broken, ground or otherwise destroyed without SCP-XXXX activation. As the True Vacuum effects are localized to the immediate dimension, high-risk pebbles may be safely stored in extra-dimensional sites. Destroying or transferring all affected SCP-XXXX masses to multidimensional sites is infeasible at this time.
All known main-sequence universes with an inhabited Earth-like planet have an SCP-XXXX phenomenon, and pebbles with similar or identical activation events and locations exist between them. [Communication is there but limited in specifics, as the pebbles are a potential weapon to use against one another]
Operation Groundbreaking:
Operation Groundbreaking is an ongoing joint Foundation-Global Occult Coalition-Department of Extra-Universal Affairs effort created to minimize the risk of a SCP-XXXX activation.
- Foundations are to commit personnel to scanning Foo-Bar machine (or equivalents) in high risk zones searching for critical risk pebbles.
- MTF research has identified recurring patterns in conditions.
- Identification, extraction and destruction or safe storage of Extreme-risk pebbles. Risk factors include number of conditions, location, easier physical trigger conditions such as "applied weight" or "sight".
The Foundation directly picks up the more dangerous pebbles (unless the condition is a Foundation employee or something in which case they defer to GOC) and destroys them. Classes of pebbles have been noticed and so we implement various societal changes to make broad classes of pebble destruction more unlikely. E.G shutting down particular religions, particular instruments or genre of music, adjust ocean currents so less pebbles are formed. Also pebbles with conditions like "stepped on" or "applied weight" are more dangerous.
All known main-sequence universes with an inhabited Earth-like planet have a SCP-XXXX phenomenon, and pebbles with very-similar or identical conditions exist between multi-dimensional Foundations. Multi-universal cooperation and postmortem analysis have yielded. MTF produces check-list adjusting for technological and influence levels of Foundations in various universes. Here's a partial collapse list of Universe-173 compliance.

Risk Analysis:
SCP-XXXX is responsible for a large portion of observed VK-End of Universe scenarios. 8% of known main-sequence universes have undergone a confirmed or suspected SCP-XXXX activation event, accounting for at least 40% of known universal collapses. The frequency of SCP-XXXX events are expected to increase as populations grow.
Universes with fully compliant Foundations (or equivalent organizations) are over six times less likely to experience an SCP-XXXX event. Accounting for the baseline Foundation's partial compliance and projected population growths, Universe-173-Alpha currently has a X yearly hazard rate. We estimate over a 40% chance of an event in the next 50 years and over 90% in the next 100 years without further intervention.
