SCP-667-1 prior to trimming

Item #: SCP-667
Object Class: Keter
Special Containment Procedures: The primary sample of SCP-667-1 is to be trimmed to an area of 0.5 sq km and maintained regularly to prevent it from expanding outside its current habitat. The perimeter of SCP-667-1's habitat is to be cleared of vegetation in a 30 m radius and fenced to prevent unauthorized access, and a region within a 3 km radius of the habitat is to be designated off-limits to civilian hikers or recreationists to prevent contact with SCP-667-2. Surveillance personnel are authorized to employ pesticides or fire to neutralize any instances of SCP-667-2 attempting to exit the containment zone.
During periods when SCP-667-2 is observed to be active, maintenance personnel are to withdraw from the habitat. An individual adult mammal, or an individual D-class awaiting scheduled termination, is to be introduced into the habitat after being tagged with a radio tracking or GPS device. D-class personnel may be issued audio or video equipment at project manager discretion. Feeding is to continue at a rate of one individual per day until SCP-667-2 becomes inactive.
Additional samples of SCP-667-1 may be produced from cuttings and grown within prescribed limits in a fully contained area at O5 discretion. All attempts to capture a live sample of SCP-667-2 are currently prohibited pending development of a means to counteract its mind-affecting properties. Any SCP-667-2 remains recovered are to be transferred to Site 73 for necropsy, analysis, and archival.
Description: SCP-667 is a symbiotic pairing consisting of a colony of flowering vines of an unclassified species morphologically similar to Pueraria lobata ("kudzu"), designated SCP-667-1, and an unclassified species of flying creatures possessing insectoid and humanoid morphological qualities, designated SCP-667-2. The only known instance of SCP-667 in the world is located in a wilderness area in the southeastern United States, approximately ██ km north of ██████████, ██, and covered an area of ██ sq km prior to being trimmed to its current size. Forensic analysis of skeletal remains found within SCP-667-1 indicate that it was introduced to the region shortly after the introduction of kudzu to the United States in the late 19th century.
In the presence of adequate nutrition, SCP-667-1 is capable of growing at a rate considerably greater than that of the standard kudzu plant; samples in captivity, under ideal conditions, have been observed to grow as rapidly as 2.5 meters per day. SCP-667-1 is capable of planting roots in almost any form of soil or soft organic tissue and will grow along or over the surface of any foreign matter in the path of its growth, including trees, structures, automobiles, or animal life. SCP-667-1's primary source of nutrition is derived from humans or other large mammals; upon encountering a sleeping, paralyzed, or dead animal within its path of growth, SCP-667-1 will rapidly grow around and through the creature, gradually consuming and metabolizing its remains to further its growth. SCP-667-1's vines, flowers, and roots contain large quantities of alkaline compounds which render it unpalatable to human beings and all other animal species (besides SCP-667-2) on which it has been tested.
Mature SCP-667-2 organisms are approximately 7.5 cm in length, with two large wings extending the entire length of the organism. Dissections indicate that SCP-667-2's internal biology is similar to that of insects of the family Lampyridae ("fireflies"). SCP-667-2's exoskeleton strongly resembles a miniaturized human being, with the organism's thorax being contained within the chest cavity and the abdomen and bioluminescent organ concealed within the legs. Male and female SCP-667-2 organisms have been recovered; female SCP-667-2 organisms reproduce by laying eggs which hatch as larvae, burrowing into the soils underneath SCP-667-1 and emerging as mature insects the following year. The current wild population of mature SCP-667-2 organisms at any given time is estimated to be less than 5,000; as many as ██████ are believed to have existed prior to trimming.
Mature SCP-667-2 organisms dwell exclusively on, underneath, and around SCP-667-1, and subsist by feeding on the nectar produced by SCP-667-1's flowers. When SCP-667-1's growth begins to slow due to deficiencies in its food supply, swarms of several hundred SCP-667-2 organisms separate from the main colony and will travel outward until encountering any medium-to-large sized mammal in the area. SCP-667-2 swarms are almost always active only during nighttime hours and are bioluminescent, producing a highly visible green glow throughout the entire organism. All human beings directly observing an SCP-667-2 swarm have described a strong hypnotic effect and a compulsion to follow the swarm, which inevitably results in the swarm leading the mesmerized human to the edge of SCP-667-1's current path of growth; non-human mammals have similarly displayed a compulsion to follow the swarm and obliviousness to outside stimuli. Upon reaching the edge of SCP-667-1, the mesmerized individual will sit or stand still and continue to observe the swarm until dying of thirst, exposure, or as the result of being engulfed by SCP-667-1. At the time of trimming, skeletal remains of approximately ██████ distinctly identifiable mammals, including ███ humans, were recovered from the cleared area.
SCP-667 came to the Foundation's attention in 20██, following a dramatic increase of missing persons within the [REDACTED] Wilderness Area in the state of ██. United States Forest Service officials identified SCP-667-1 as the cause of the missing persons, and upon the loss of several personnel to SCP-667-2 swarms contacted the Foundation's liaison within the Department of Agriculture, leading to the establishment of Foundation containment over the area. At the time of discovery, SCP-667-1 had become highly invasive and its growth was projected to reach the outskirts of the city of [REDACTED] within less than a decade; approximately 9█% of SCP-667-1 was destroyed by incineration, under pretense of a forest fire, in order to reduce the colony's size to a manageable level. Examination of the region indicates that almost all of SCP-667-1's growth had occurred within the past 20 years; the Foundation's current working hypothesis is that SCP-667-2 was introduced to the region within that time, and that the development of a symbiotic relationship between itself and SCP-667-1 allowed it to begin expanding outward at a significantly greater rate than it had previously.

Item #: SCP-668
Object Class: Euclid
Special Containment Procedures: [REVISED] As of [DATA EXPUNGED], no special containment procedures aside from standard security are required. SCP-668 is to be transferred to a locked safe-deposit box at Site 19's High Value Item Storage Facility. Standard defenses against intrusion (explosive, chemical, biological, and memetic) are to be in place at all times, according to standard operating procedure.
SCP-668 may only be removed from its safe-deposit box by personnel with Security Clearance 2 or higher. Individuals wishing to make use of SCP-668 outside Site 19 must first submit a Form-668 Requested Course of Action form to O5-11 and be fitted with an explosive killswitch collar on a 24-hour timer before taking SCP-668 into the field. An Auditing Officer with Security Clearance 4 or higher must confirm that SCP-668 has been returned to its safe-deposit box before the collar is deactivated.
Description: SCP-668 is a 33cm (13in) chef's knife with a rosewood handle and full-tang construction, crafted at some point from the late 1930s to the early 1940s. When first acquired by field operatives, SCP-668 was in badly rusted condition, with heavy pitting from blood stains and other bodily fluids trapped in micro-crevices within the blade. Following thorough analysis, these irregularities were removed for aesthetic purposes. This has had negligible, if any, effect on SCP-668's special properties.
The first recorded appearance of SCP-668 was in the 1960s, during the infamous [DATA EXPUNGED] case. [DATA EXPUNGED], a New York woman living alone, was allegedly raped and murdered by subject [DATA EXPUNGED]. Despite the fact that 38 witnesses reported hearing the attack, none of them attempted to aid the young woman for over six hours, until her eventual death. Whether the item received its properties due to this event, or whether it had them beforehand, is a matter of debate (see Dr. [REDACTED]'s paper re: the Bystander Effect, vs. Dr. [REDACTED]'s theory regarding psychic imprintation.)
What is clear, however, is its current properties. When carried by a human or humanoid entity with violent intent towards another human or humanoid entity, SCP-668 broadcasts a psychic signal that renders all sentient beings with a Psionic Resistance Index of 97 or lower incapable of assisting the victim. Affected entities report a sudden sense of apathy while under SCP-668's influence: sensory input is not affected, and affected entities report feeling revulsion and horror, but are simply incapable of acting, even indirectly, to assist the victim. Meanwhile, it renders the victim incapable of defending themselves against their attacker.
Tests using Class-D personnel have shown no upper limit in the number of entities affected by the psychic resonance. In one test, twelve Class D Personnel due for first-of-the-month termination were placed in a room alongside a researcher who was told to randomly select one test subject for death. The researcher killed all test subjects one by one, despite their professed horror. Prior incidents have indicated the possibility of hundreds, if not thousands of deaths due to SCP-668's unique properties (see Incident Report 668 A re: [REDACTED] Mall massacre and subsequent information blackout operations).
Recovery of SCP-668 in such scenarios is problematic due to the item's psychic properties. Agents attempting to apprehend the subject during Containment Failure Incidents are often themselves affected by SCP-668's so-called "Apathy Field," resulting in casualties among Foundation personnel. Following Incident 668-A, standard retrieval protocol includes the use of a long-range sniper rifle, double-blind conditions, and three different agents working in tandem through carefully coordinated actions to prevent any of them realizing that they are actively opposing the subject.
Because of the obvious apocalyptic possibilities, it is the recommendation of this panel that SCP-668 be designated a Keter-level threat and placed in high-level confinement.
Addendum 668-a: Following further testing, it has been determined that test subjects wielding SCP-668 can be terminated through passive response, so long as the terminating agent is introduced before the subject takes possession of SCP-668. The Running Man protocol (see Appendix 668-B: Approved Terminating Agents) is hereby approved for use with SCP-668, and the item in question is hereby reclassified as a Euclid-type object.
Addendum 668-b: Use of Omega-7 personnel for retrieval of SCP-668 during future Containment Failure Incidents is to be hereby forbidden due to the danger of SCP-076-2 coming into contact with the item. Addendum 668-b is revoked as of [DATA EXPUNGED] due to SCP-076-2's expressed distaste at using an item that, in its own words "takes all the fun out." Possibility of using SCP-076-2 as a solo agent for any future Containment Failure Incidents under review. With the ending of the Omega-7 project, no further attempts to weaponize SCP-076-2 or SCP-668 are to be attempted.
Addendum 668-c: Do not, under any circumstances, allow SCP-668 to come in contact with SCP-682. Note that although average human beings have a Psionic Resistance Index of 24, SCP-682 has been tested with a PsiRI of [REDACTED] placing it above SCP-668's threshold of effect. The possibilities of a creature inimical to all life gaining possession of something like this should be obvious. With the ending of the Omega-7 project, no further attempts to weaponize SCP-682 or SCP-668 are to be attempted.
Addendum 668-d: Request to reclassify SCP-668 under its original designation as a Keter-class object under review.
Addendum 668-e: Request to reclassify SCP-668 under its original designation as a Keter-class object denied. SCP-668 will remain at Euclid classification.

Item #: SCP-669
Object Class: Safe
Special Containment Procedures: SCP-669 is to be kept in a lead-lined safety deposit on Site-19. Any personnel to be granted access to SCP-669 must have completed a training session led by an individual with 2/669 clearance.
Following Incident 669-1, SCP-669 is to be encased in a Faraday cage vessel consisting of a grounded copper shell, and slotted alumina inserts holding the item in place. SCP-669 is to be removed from containing vessel only in designated testing area, so as not to interfere with Site-19 electronics.
Description: SCP-669 is a sphere of radius 2.6cm, resembling a large bearing. When inactive, SCP-669 weighs approximately 560g. The surface of SCP-669 contains numerous sites of corrosion and pitting, as well as remains of a cadmium blue paint. The surface temperature of SCP-669 appears to vary between 32.1 and 33.8 degrees Celsius - this appears independent of the temperature and thermal conductivity of its surroundings.
The composition of SCP-669 is currently unknown; the surface of SCP-669 indicates its composition to be mild carbon steel, however, its density, as well as inertia testing data suggests a non-uniform internal structure.
SCP-669 activates when placed within 54 cm of any object larger than itself, and set into motion. While active, SCP-669 appears to lack gravitational mass - instead it describes an orbit around the object at one of a set of distances up to 54 cm from the object's surface.1 Collisions with an object larger than itself cause SCP-669 to relocate into orbit around the colliding object.
If SCP-669 is exposed to a suitable light source of sufficient brightness (see Experiment Log-669), it proceeds to move into the next further orbit. If no such orbit exists, SCP-669 will either deactivate, or proceed to fly at a tangent to its original orbit until colliding with another suitable object.
Pushing SCP-669 into an orbit closer to an object it orbits requires a force of approximately 50N, and is accompanied by a brief photoemission of seemingly random frequency from SCP-669's surface.
Recovery Log: SCP-669 was recovered from the depositary of Istanbul Modern Art Museum on April 4, 195█ having been previously exposed in the annual "Current Eastern European Sculpture" retrospective, as a part of an exhibit titled "Rutherfordian Atom - A Didactic Perspective".2 SCP-669 was not listed in that exhibition's catalog and neither its purported artist, one G█████ P█████████████, nor "Lomonosov-Makarenko Institute for Scientific and Political Education" appear to figure in any official records.
Incident 669-1:

On ██/██/196█ during the course of an experiment led by Researcher Arnold Scheiner, SCP-669 deactivated after a minor collision. Within 15 seconds of reactivation, SCP-669 suddenly developed an electric field sufficient to strip electrons from objects within a radius of approximately half a metre, resulting in the death of Researcher Scheiner, and extensive damage to electronic devices in the laboratory and adjacent areas. Containment procedures updated.

Footnotes
1. SCP-669 always orbits at one of a set of four to nine discrete distances located in the range 0cm-54cm, however, the precise values vary with every activation.
2. Visual records recovered indicate that the exhibit contained █ further instances of SCP-669 as well as an agglomeration of at least ██ similar objects, none of which were recovered.

Item #: SCP-670
Object Class: Safe
Special Containment Procedures: The family unit collectively referred to as SCP-670 is currently contained at Sector 25, located in ███████, England. Members of SCP-670 are to be contained in a shared 12 m x 6 m holding cell, observed via surveillance camera. Cell is to contain four (4) beds, a bathroom, and an observation window. All staff entering SCP-670's containment area are to be searched for lighters, matches, and other sources of open flames.
SCP-670 is to be provided with forty-five (45) centimeters of cotton, twenty-five (25) centimeters of silk, twenty-five (25) centimeters of polyester, fifteen (15) centimeters of rayon, and twelve (12) centimeters of rope each month. Any objects created by members of SCP-670 that could be used as a weapon are to be immediately removed from the containment area.
Description: SCP-670 is comprised of four roughly humanoid individuals, SCP-670-1, SCP-670-2, SCP-670-3, and SCP-670-4, who refer to themselves collectively as 'the Cotton family'. SCP-670-1 and SCP-670-2 appear to be the 'father' and the 'mother' of the family, judging by their height and comments made in interviews, while SCP-670-3 and SCP-670-4 are the 'children' of the family. Members of SCP-670 possess a thin outer layer of hardened clay 'skin', showing signs of deterioration from over a long length of time.
Under this, the organs, flesh, and nervous system are composed entirely of different types of thread. The majority of the thread used is cotton, but large amounts of silk and polyester are also present. Small amounts of rayon and nylon are also noted in the internal organs. The skeleton is composed of rope knotted into a suitable shape and the fingers of SCP-670 members seem to be rusted sewing needles.
Members of SCP-670 have demonstrated an advanced aptitude for the use of thread, using their 'fingers' to create extremely complicated objects, such as suitable eating implements and seating, in a short amount of time. Notable objects created by members of SCP-670 include:

One (1) bicycle (functional)
One (1) television (non-functional)
One (1) clock (functional)
One (1) roast chicken (consumed by members of SCP-670)
One (1) detailed family portrait
One (1) dagger (See Interview 670-1-1)

Members of SCP-670 show discomfort when using objects not composed of thread, such as plastic chairs or writing implements. The reason for this is currently unknown, and members of SCP-670 refuse to elaborate on it.
SCP-670 was first discovered at ████████ Forest, near ██████████, when a group of hikers reported that they had found 'a house made of rope' in the forest. Agents were dispatched to investigate the matter and discovered SCP-670. The hikers were dosed with Class-A amnestics and SCP-670 was brought into containment without incident.

Interview SCP-670-1-1

 ...

Interviewed: SCP-670-1
Interviewer: Dr. ███████
Foreword: At approximately ██:██ on ██/██/20██, SCP-670-1 constructed a dagger using SCP-670's monthly thread ration. The dagger was immediately confiscated and SCP-670-1 brought in for questioning.

<Begin Log>

(SCP-670-1 is brought in by security)

Dr. ███████: Hello, SCP-670-1. Please, have a seat.

SCP-670-1: (Looks down at seat) Um, do you have any other chairs?

Dr. ███████: I'm afraid not.

SCP-670-1: Can I stand?
Dr. ███████: No.

(SCP-670-1 sits down.)

SCP-670-1: So, um, what's this about?

Dr. ███████: I understand you made a dagger earlier today. What did you intend to do with it?

(SCP-670-1 seems confused at this point.)

SCP-670-1: I don't see what…Oh! Oh my goodness, no! I'm not a violent man, sir!

Dr. ███████: I see. However, if you didn't intend to escape, what was it for?

SCP-670-1: Rodents, sir.

Dr. ███████: I'm sorry?

SCP-670-1: Well, I've been hearing squeaking the last few nights and I thought I should try and get rid of the rats. They spread disease, you know.

Dr. ███████: Alright…well, while you're here, SCP-670-1, I'd like to ask you a few questions.
SCP-670-1: I'll try my best, sir.
Dr. ███████: Can you please tell me where and when you were born?
SCP-670-1: ██████████, 18██, sir.
Dr. ███████: Do you have any relatives?
SCP-670-1: Yes, sir, my two children, Alfie and Elizabeth.
Dr. ███████: I mean parents.
SCP-670-1: Oh, you mean Grandad Cotton?
Dr. ███████: Can you tell me more about 'Grandad Cotton', SCP-670-1?
SCP-670-1: Well, he was a clever guy, good with his hands…(gestures at himself) as you can see…Don't really remember much about him, he died a while back. Great guy, though.
Dr. ███████: Well, can you tell me how you met your wife?
SCP-670-1: (Appears uncomfortable) I don't quite remember that, sir. It was a long time ago.

Dr. ███████: Well, that's all for now. SCP-670-1, please return to your containment area. We won't tolerate weapons again.

SCP-670-1: Sorry, sir.

<End Log>

Closing Statement: SCP-670-1 was returned to the containment area and is currently under heightened surveillance.

Incident 670-1

 ...

SCP involved: SCP-670
Date: ██/██/██
Location: SCP-670 containment area.
Description:
7:40 PM: Members of SCP-670 are consuming a polyester steak. SCP-670-3's eating implements slip out of its hands. SCP-670-3 suffers a small laceration on its left leg and attempts to conceal it. Other members of SCP-670 do not notice this laceration.
8:10 PM: Members of SCP-670 are conversing while seated. SCP-670-3 stands to get up, but stumbles, revealing its injury. The other members of SCP-670 quickly approach.
8:11 PM: SCP-670-1 and SCP-670-4 restrain SCP-670-3. SCP-670-2 begins to carefully remove outer clay layer from SCP-670-3. SCP-670-3 vocalizes its distress at this point, and continues to do so until 8:19 PM.
8:13 PM: SCP-670-3's outer layer is completely removed. A stitched together inner layer of red cotton is visible. SCP-670-2 begins to unstitch this inner layer.
8:15 PM: SCP-670-2 deposits unstitched cotton thread on the cell floor. Inner workings of SCP-670-3 are now visible, including the 'heart' and 'lungs'. SCP-670-2 begins unstitching the lungs.
8:17 PM: SCP-670-2 deposits unstitched polyester thread from the lungs next to the cotton thread. SCP-670-3's attempts to escape become less violent. SCP-670-2 begins unstitching the heart.
8:19 PM: SCP-670-2 deposits unstitched nylon and polyester from the heart. SCP-670-3 ceases movement and vocalizations at this point, presumed dead. Central nervous system, brain, and skeleton are now visible.
8:25 PM: SCP-670-2 has unstitched the brain and central nervous system. Begins untying the skeleton.
8:28 PM: Skeleton is untied and placed next to other disassembled materials of SCP-670-3.
8:29 PM: SCP-670-1 approaches observation window and requests identical materials to those currently on the cell floor. Request accepted.
8:34 PM: Requested materials are brought in by two D-class personnel. SCP-670-2 requests that the clay 'skin' is not removed, but other materials are delivered without incident. The materials that comprised SCP-670-3 are retrieved for further study.
8:35 PM: SCP-670-2 begins creating an identical copy of SCP-670-3 from the delivered materials.
8:44 PM: Clay 'skin' is applied to copy. Copy of SCP-670-3 is completed. SCP-670-1 refers to it as 'Alfie Cotton'.
8:45 PM: SCP-670 retires to their beds.
Retrieved materials contain no anomalous properties, but study is still ongoing.

« SCP-669 | SCP-670 | SCP-671 »


Item #: SCP-671
Object Class: Euclid
Special Containment Procedures: SCP-671 must be kept at Sector-██ in a clear plastic terrarium no less than 10m x 1m x 1m. The terrarium is to be assembled by heat merging only. It should contain at least 400 kg of sandy soil with humidity at least ██.█%. Appropriate food is provided via a hatch every week. The room is to be monitored by four cameras at all times. Entry and exit is via an airlock, which must be flooded with an insecticide harmless to humans each time it cycles. No piece of the door beyond the innermost panel itself may be accessible from inside the containment room, and all fixtures inside the room must be either sealed or built into the walls.
As long as any SCP-671 individuals are outside the terrarium, personnel entering the room must either wear only clothes that will not trigger SCP-671, use strong insect repellent, or wear a sealed single-piece suit over all other clothing. All but the simplest items must be kept within a sealed transparent plastic bag or similarly protected by insecticide or repellent. Should SCP-671 individuals escape the terrarium outside of experimental procedure, the room is to be flooded with insecticide.
No SCP which can potentially be disassembled is to be kept at Sector-██, and SCP-671 may never enter a facility where such SCPs are kept.
Description: SCP-671 is a large colony of Spanish carpenter ants (Camponotus cruentatus), comprising approximately 30,000 individuals. When SCP-671 is faced with a complex artificial device, its constituent individuals will attempt to reduce it to its simplest components. (Organisms, living or dead, do not trigger this behavior.) The ants appear attracted to artificial devices as to food sources. Screws will be unscrewed, staples and nails extracted, etc. In the process, even a single SCP-671 individual is able to exert forces several hundred times greater than a normal C. cruentatus. When large numbers of ants collaborate, they are capable of surprising feats.
The only type of artificial joint that appears not to trigger SCP-671's disassembly behavior is that in which two items of the same or similar material are merged using adhesive of another similar material. Examples include the rocks and cement in concrete, paper glued together (unless the glue is so thick as to represent a separate "part", such as in book bindings), soldered metal, and material completely encased in other material. The ants take great care to avoid damaging an object's parts during disassembly; however, material serving as a joint (e.g. glue, mortar, rivets) is likely to be destroyed in the process.
SCP-671 reduces objects to their smallest natural constituents: fabric is frayed into constituent threads, as are textile-like objects such as rope. 15,000 SCP-671 individuals, working in concert, can disassemble a sedan in 48 hours or a 10-story steel-frame building in one month. They show little intelligence beyond that strictly necessary for disassembly, and will mindlessly attempt to take apart running machinery or containers of poison at great risk to themselves and the colony. In ████ of ████ at Alcanar, Spain, a group of SCP-671 individuals proceeded to disassemble the motor of a running tanker truck, resulting in [DATA EXPUNGED]. As such, if necessary, it may be possible to reestablish containment by leaving large multi-part containers of insecticides or corrosive substances near the colony.
Addendum: Following Incident 671-A, personnel are reminded that any appropriate "sealed single-piece suit over all other clothing" must also cover the feet. Suits which include separate foot covers, such as used on some other SCPs, are not appropriate for interaction with SCP-671. — Dr. Ziegler
Incident 671-A: Agent Thornton, having just left an experiment with SCP-███, assumed that his airtight suit would be sufficient for subsequent work with SCP-671. Almost as soon as he entered the colony's containment, however, the ants began to disassemble his military-type boots. As he prepared to leave, he tripped over the shoelaces that had been undone and partly frayed and fell to the ground, suffering a sprained knee and dislocated shoulder.

Item #: SCP-672
Object Class: Euclid
Special Containment Procedures: The sample kept at Research Sector-██ is to be maintained in a biodome suitable for desert life with accompanying scrub plants. Samples may be taken at the discretion of Dr. H█████. [REDACTED] is to have relevant data for the location of SCP-672 colonies uploaded. Any wild colonies are to have an MTF dispatched to enact procedure Lambda-6.
Description: SCP-672 is a species of coral that grows in desert environments. The rich green color of SCP-672, making it appear as a plant at first glance, comes from a previously undiscovered but unremarkable species of zooxanthellae. The colony is extremely efficient with resources. Dead individuals are broken down and any useful components redistributed, leaving behind limestone that can only be distinguished from deposits formed by normal coral by the presence of [REDACTED]. When not active, SCP-672 polyps completely seal themselves within their shells and become nearly impossible to distinguish from surrounding rock formations. It is recommended that MTFs carry a copy of Document 672-12 as an identification aid when performing fieldwork relating to SCP-672. Outside of expansion events SCP-672 will periodically become active for brief times to either consume prey or to allow its zooxanthellae to undergo photosynthesis.
SCP-672 was initially discovered by a [REDACTED] in 19██: a sleeper agent planted in the team alerted the Foundation to a possible SCP species and attempted to direct attention away from SCP-672 as per standard procedure but was detained by his fellow researchers due to suspicious behavior. Agent D█████ attributed his detention as the primary reason for surviving the subsequent expansion event that killed the rest of the expedition.
SCP-672 feeds when an animal touches a polyp, either by chance or having been lured during an expansion event. The polyps with access to prey use a radula to tear off small pieces of food— test subjects report feeling like they have scraped their hand against sharp stone even when lightly touching SCP-672. Observation of injuries caused by SCP-672 feeding have shown the polyps to coordinate their motion to keep the damage consistent with a scraping injury. Polyps pass food around the colony via laterally placed holes in their shell, allowing the whole reef to stay fed. This feeding behavior is relatively harmless and subjects have successfully maintained prolonged contact with SCP-672 without severe damage.
SCP-672 only poses a real threat during an expansion event, during which the colony attempts to draw in as much prey as possible leading up to its reproduction. SCP-672 will begin emitting a pheromone that has been demonstrated to create a desire in vertebrates to move towards its source. Victims attempt to make as much skin contact as possible once they reach SCP-672, allowing it to feed upon them with maximum efficiency. Reptiles are most affected by the pheromone, some documented as being attracted from up to six (6) kilometers away while the maximum range of effect for birds and mammals is closer to two (2) kilometers. Upon cessation of pheromone production SCP-672 emits a cloud of spores, most of which settle on and around SCP-672 with large amounts collecting on prey caught upon the colony. Any surviving victims return to normal behavior once the pheromone disperses and will generally flee the area. Spores caught on these animals remain dormant until death and will grow to become a new colony on the corpse.

Item #: SCP-673
Object Class: Keter
Special Containment Procedures: No living tissue is to enter the main containment area while SCP-673 is present. Dual air lock systems separated by decontamination and scanning cells are to be maintained at all times. Containment cell is to be immediately locked down during any maintenance or power failures, with release only after review by Site Security. Equipment exiting the containment cell is to be sterilized and remain in quarantine for a minimum of two weeks before being reused.
Containment cell maintenance is to take place only after SCP-673 has been removed to a temporary containment cell. All surfaces are to receive treatment by chemical agent NioX-9, with any overgrown areas extracted and rebuilt. Containment cell must be cleared of all personnel for no less than 12 hours before SCP-673 can be replaced to primary containment cell. Temporary containment cell is to be flooded with NioX-9 for no less than 48 hours after SCP-673 removal.
Independent instances of SCP-673 are to be severed and isolated as soon as possible after initial discovery. Evaluation of newly severed instances is to take place within five to eight hours post-severing. SCP-673 instances found to have no research, production, or other value are to be incinerated immediately after evaluation. Instances added to the main contained mass are to be recorded and logged with Central Records.
Any staff working in or around the containment area are to be placed in quarantine immediately after completing their given tasks. Observation of quarantined subjects is to continue for a minimum of two weeks. Any erratic behavior, growths, or other SCP-673 symptoms exhibited by subjects is to be reported to Site Command, with subjects being held for eventual evaluation.
Description: SCP-673 is a mass of organic tissues, connected in what appears to be a totally random assembly. These tissues include recognizable structures, such as hearts, digestive tracts, blood vessels, and brain matter; however, many tissue structures are not identifiable by composition or purpose. Tissue structures are also noted for their increased size, appearing twenty to fifty times as large as their normal counterparts. Sample tests have shown the basic structure of SCP-673 to have no known counterpart among normal organics, and lacks any form of DNA or normal cellular composition.
Tissues appear to operate without the need for any outside stimulation or substance, with "hearts" beating for days with no blood or nerve connections, and "lungs" continuing to expand and deflate even when severed and fully submerged. Tissues, isolated from the main mass, will "grow" into surrounding structures, using what appear to be tendons or thin bone-like structures to penetrate and spread over walls, floors, and ceilings. Tissues will "operate" indefinitely, with no tissue decay normally associated with exposed organs.
SCP-673 appears to be infectious by an unknown means, with physical contact being the only constantly observed transmission method. Instances of "airborne" transmission have been reported, but are extremely rare. SCP-673 appears to "prefer" organic tissue, but will integrate with inorganic structures at a slower rate. Testing has shown that tissue integration appears to progress along loose guidelines in regards to inorganic structures. Pipes become veins and tracts, beams become bone-like supports, doorways become valves, etc. in a slow progression. The SHeLL project[2] has shown that, with sufficient space and ample amounts of organic materials, SCP-673 [DATA EXPUNGED]

Addendum:
[1] NOTE: ORGAN DOMINANCE RESULTING IN TISSUES WITH NO HUMAN ANALOG MAY PRODUCE UNIDENTIFIABLE BEHAVIORS. ALL RECORDS OF SUBJECTS PRODUCING NONHUMAN TISSUE ARE TO IMMEDIATELY BE REMANDED TO CENTRAL RECORDS. ALL SCP-673 SUBJECTS ARE TO BE OBSERVED AND RECORDED CONTINUOUSLY DURING CONTAINMENT.
[2] Full records of SHeLL project available pending O5 review. Partial transcripts available to LEVEL 4 cleared staff pending approval by Central Records.

Document 88-9-R: Infection Progression
Initial stage infection begins at point of contact in 96% of all cases. Physical contact with SCP-673 will cause subjects to develop a small rash at the point of contact, which will fade within two hours. Subject will start to exhibit erratic behavior 4-5 days post-contact, with said behavior becoming more pronounced as infection continues. Behavior varies between infections, with increased appetite, paranoia, inappropriate appetite, and increased libido among common symptoms. There is no consistent behavior progression or development; however, behaviors appear to relate to the end-stage organ dominance.
Mid-stage infection is variable, most often observed between 2-3 weeks after initial contact. Subjects will start to exhibit physiological changes, such as distortion of the physical frame, loss of hair/fingernails/skin, loss of bone density, lesions, abnormal bone growth, rash, increase/decrease of bodily fluids, and general muscle atrophy. Subjects will begin to exhibit "organ dominance", with one or several areas of the body beginning to swell rapidly and absorb surrounding tissues. Subjects behavior will begin to centralize around these areas (example: "stomach-dominance" subjects engaging in continuous gorging, "heart-dominance" subjects going into prolonged, violent and rhythmic spasms).[1]
End-stage SCP-673 sets in 5-6 weeks after initial contact. Subjects will begin full integration with the dominant organ growth. Subjects will typically lose locomotion and the capacity for speech at this stage. Subjects appear to no longer require basic human needs such as food or oxygen, and behave as a parasite on the main organ. Bodily tissues are absorbed and integrated by the forming SCP-673 organ body, with full absorption taking place 24-48 hours after end-stage onset. Any remaining will or mental capacity is deemed negligible at this point, with most "emotional manifestations" vanishing within 2 weeks.

Document OO-3: SHeLL Project Memo to project staff:
Let it be noted that instances of "attacks" by SCP-673 masses are easily attributable to random organ spasms observed in nearly all instances of SCP-673. Listing these incidents as "attacks", especially in security documentation, is irresponsible to the point of dangerous, and will constitute disciplinary action in the future.
SCP-673 masses lack any appreciable nervous system in most cases, and "will retention" is nil. Incidents of "escape attempts" and "communication" are clear examples of anthropomorphism and misidentification, and are therefore not appropriate topics of study. Proposals to open "dialog" with nervous system clusters will be subject to Project Command review and discipline.
Dr. Kinder's "incident" should be a sufficient example regarding the need for professional detachment and logical thinking. A new project head will be appointed within the week, with Dr. Aarons taking interim control.

« SCP-672 | SCP-673 | SCP-674 »


Item #: SCP-674
Object Class: Safe
Special Containment Procedures: When not being tested, SCP-674 is to remain in a locked plastic case in Storage Site-23. SCP-674's cord is not required for its operation and is to remain coiled and tied. SCP-674 poses no existential threat to anyone other than its user; however, it has already demonstrated itself to be a potential security risk for the Foundation. Therefore in the event that security around SCP-674 is compromised, on-site personnel are authorized to destroy it at their discretion. Testing is ongoing to determine the risks and possibilities in using SCP-674 as an information gathering device.
Description: SCP-674 is a "Zapper" light gun peripheral for the Nintendo Entertainment System, consistent with other models that were bundled with the NES in North America after 1985. SCP-674 displays typical wear and tear and some indication that previous owners tried to pry the casing open unsuccessfully. The device is not indestructible and has responded to stress tests as expected. Disassembling and reassembling the device has revealed no anomalous parts or internal tampering. Cleaning and maintenance of its parts appears to have improved its accuracy but has not removed a blind spot that begins on the extreme right side of any screen it is aimed at.
When SCP-674 is aimed and fired at any video screen, the user perceives that he or she has fired a shot into the displayed scene. Any physical object within the scene, whether live or previously recorded, will react appropriately in context. People who are shot will appear to die or be wounded, and other people in the scene will duck, take cover or flee off camera. It must be noted that this will not correspond with reality outside of the video and no one beyond the user of SCP-674 will perceive the change. Results will vary depending on the context of the video. Fictional characters in a television show will react consistently within the established parameters of their setting, while firing into news reports or documentaries will produce a realistic reaction. Therefore, shooting at an actor in an interview will produce a different result than shooting at the same actor who is currently portraying an invincible cyborg in a science fiction movie.
Animated cartoons can also be affected, although "cartoon logic" produces wildly unpredictable results ranging from causing a character to momentarily be obscured by a puff of smoke and be covered with soot afterward, to [DATA EXPUNGED]
The most notable result of use of SCP-674 is that it is permanent and can lead to very unusual experiences for the viewer. If a subject uses the device to shoot a character in a television series, they will forever perceive that they have changed the continuity of the series. A character will remain wounded or dead, and other characters will respond in context. This will continue even if SCP-674 is only used once and the viewer is never exposed to it again. At a certain threshold, fictional characters will begin to make broadly expositional statements to each other or through the "fourth wall" regarding the actions of the viewer, potentially divulging sensitive information. See Addendum for details.
Addendum: SCP-674 was recovered from the home of M████ S███████, a reclusive 33-year-old Caucasian male. Mr. S███████ came to the attention of the SCP Foundation through posts on his fringe political blog, in which he had claimed to have assassinated then-President ██████ █ ████ and then-Vice President ██████, along with half of Congress, four members of the Supreme Court, and a wide range of news anchors, talk show hosts and political commentators. Questioning of the subject revealed that he never left the house and honestly believed the news reports he was watching and using SCP-674 upon were real. Mr. S███████ claimed that he was using SCP-674 to stave off a military police state; however, using the device to "assassinate" so many high profile figures had the opposite effect on the video reality he was experiencing. His final blog posts described an increasingly unstable global order, martial law, and detailed descriptions of catastrophes consistent with the hypothetical release of SCP-███ and SCP-███, among others.
Mr. S███████ claimed prior knowledge of the Foundation and was laying in wait for agents, attempting to ambush them by firing SCP-674 into monitors attached to his home security system upon their approach. This, of course, had absolutely no effect on the agents who immediately took him into custody and seized SCP-674. Under questioning, Mr. S███████ said he had discovered the properties of SCP-674 when he idly aimed and fired it at an episode of the cartoon ██████████, when one of the main characters was wearing a graduate's cap and singing about geography. He claims that after the character recovered, it wagged a finger at him and specifically warned that the SCP Foundation was "going to get him" if he continued to fire the device before returning to its song.
Mr. S███████ perished while held in confinement. Security tapes show he had been alone and engaged in a heated one-sided argument with the security camera in his cell before being struck down by three .38 caliber handgun bullets.
Testing Log SCP-674-1
Note, this text log was retrieved from the hard-drive of Dr. ██████'s partially melted laptop in his private quarters. Dr. ██████ had checked SCP-674 out for testing and it was also recovered from his quarters. Dr. ██████'s whereabouts are unknown.

Item #: SCP-675
Object Class: Safe
Special Containment Procedures: The house containing SCP-675 has been designated Observation Post 9010. One researcher must be stationed within Observation Post 9010 at all times. Monitoring of SCP-675 is to be undertaken in 30 day shifts. No researcher may return to Observation Post 9010 before a minimum of six (6) shifts have passed. All researchers assigned to SCP-675 must undergo mandatory psychological screening prior to and after a completed shift in SCP-675.
All researchers monitoring SCP-675 must record any and all observations on an audio recorder. Following Incident 675-1, all researchers must be under video surveillance at all times.
Description: SCP-675 is a standard window and frame found in the northwest portion of Observation Post 9010, in the living room area. During random time intervals, shadows resembling humanoid figures (designated as SCP-675-1) can be seen through the window. These shadows are visible at all times of the day and night, and are seen to be visually distinct from normal nighttime darkness. These instances are only visible from within Observation Post 9010. It is currently hypothesized that SCP-675-1 instances are trans-dimensional beings, and that SCP-675 functions similarly to SCP-1278 and SCP-1288 as a means of viewing them.
In order to aid in observation, a thin screen has been attached over SCP-675. This screen acts as a projection surface, on which SCP-675-1 instances can be seen more easily.
SCP-675-1 instances often engage in actions such as tapping on the glass of SCP-675, conversing with one another, and various other benign actions. These are to be considered normal, and as of yet, SCP-675-1 instances have never engaged in any hostile actions.
SCP-675's secondary anomalous effect is a hallucinogenic effect manifesting in individuals who remain in Observation Post 9010 for longer than approximately 45 days. Subjects who remain in the proximity of SCP-675 for longer than approximately 45 days become convinced of the malevolent nature of SCP-675-1 instances. The longer that subjects are exposed to SCP-675, the more extreme these hallucinations become. Subjects report that SCP-675 is a gateway to another dimension that is populated by SCP-675-1 instances, and that these instances seek to invade this dimension and "cleanse it."
Subjects will reiterate the need for individuals to prepare for the coming invasion by SCP-675-1 instances, and will seek to ensure that SCP-675 remains closed at all times. Subjects also report that SCP-675-1 instances will attempt to communicate with them, and that the content of such messages is often disturbing in nature. In a few instances, subjects will report that the SCP-675-1 instances are preparing for a trans-dimensional invasion of the Earth. Such reports are unsubstantiated, as audio surveillance currently reveals no such sounds.
The current video surveillance and rotations were enacted due to several breaches in which researchers constructed fortifications and preparations for the believed invasion by SCP-675-1. In one extreme case, a researcher constructed an elaborate series of anti-personnel traps designed to kill or seriously maim any individuals who attempted to enter the house.

« SCP-674 | SCP-675 | SCP-676 »


Item #: SCP-676
Object Class: Euclid
Special Containment Procedures: The property containing SCP-676 is owned by the Foundation under the guise of █████████ Inc., a shell corporation. It is closed to the public, and posted signs indicate that the area is a hazardous materials storage facility.
Under no circumstances is the flow of water into SCP-676 to be interrupted. Backup tanks of water are to be used to supplement the stream's flow in the case of an obstruction. Vegetation is kept clear in a 10 m channel along the course of the stream to prevent unanticipated interruptions.
Description: SCP-676 is a hot spring and an associated 7 km long stream, located in the hills outside of ██████████████. When it was discovered by the Foundation, the basin of the spring was approximately 2 m wide, but it has since expanded to over 90 m in diameter.
The stream stretches from the ██████████ River to the hot spring. Although the spring is 750 m above the river, water in the stream flows uphill from the river to the basin. Its temperature begins at an ambient 22°C at the river and gradually rises as the stream ascends, reaching 82°C as it enters the spring. Water removed from the stream exhibits no atypical properties, and flows downhill normally if placed on an incline. Water added directly to the stream moves against gravity, as does any detritus carried in the flow.
Despite being continuously fed by the stream the water level in the basin remains constant, suggesting that it drains into the bedrock below. The water in the basin is between 81°C and 84°C, as measured by IR sensor. More direct means of assessing the temperature cannot be used, as any object placed in the water disintegrates.
Small items and organisms caught up in the stream are continuously deposited and dissolved in the hot spring. The reason for this is not known. In most cases it does not affect the walls of the basin (see test log 676-01). All tested materials introduced to the spring begin to fall apart immediately, dissolving completely within a few seconds. Dyes and radioactively labeled markers disappear as well, suggesting that the process occurs below the chemical level. As a result it has proven impossible to take and retain samples from SCP-676's basin, and it is unknown if the fluid is water or another colorless liquid compound.
Optical and sonic means of probing SCP-676 have mapped it deep underground, but have not located a destination point. Analysis of the data indicates that the surrounding bedrock is abnormally soft. This may be related to the high incidence of localized earthquakes detected in the area, and the periodic shifting of SCP-676's subterranean channels.
Experiment Log 676-01: Testing the effect of withholding the flow of water to SCP-676.
The water feeding SCP-676 was blocked at the junction of the stream and the river. The last of the water drained into the basin at 13:24:02 (local). For three hours there was no response, and water level remained constant. At 16:41:57 the walls of the basin began to disintegrate, widening the aperture steadily. This proceeded for 12 minutes, at which time the supervising researchers decided to unblock the stream. By the time flow was restored at 18:03:19, the basin had grown in diameter by 4000%, swallowing 4 structures and the majority of on-site investigative equipment. No lives were lost.
Since the incident, localized seismic activity has intensified and the stream's flow has increased by a factor of 200. Containment procedures were updated, and SCP-676's object class elevated to Euclid.

Item #: SCP-677
Object Class: Safe
Special Containment Procedures: SCP-677 is currently in the vicinity of Saturn's orbit. Due to its attraction to Earth, it is expected to land back on the planet by the year 2███. At least one telescope will be trained on SCP-677 to monitor its movement. When reentry occurs, a team will be dispatched to recover the object, whereupon it will be dismantled and returned to its storage locker at Site ██.
Description: SCP-677 is a silver, ████-brand pogo stick that has significantly visible wear. Etched onto the side is an engraving reading “For Mike: Happy Travels!” SCP-677's frame appears to be indestructible by all normal means, though it can be dismantled. The spring itself, oddly, is easily broken, though it can be replaced with any spring that will fit around the SCP's shaft. The type of spring used appears to have no effect on SCP-677's mechanics, so long as it is unbroken.
When used, SCP-677 will immediately jump to unpredictable heights and speeds, regardless of the degree of power applied to the jump. Various heights, ranging from two centimeters upwards, have been recorded, and the highest obtained speed to date, based on calculations of SCP-677's current trajectory, is █████. Maximum obtainable speed is unknown. Additionally, due to some unknown mechanic, SCP-677 always lands within ██ meters of its original launch position, regardless of the time, direction or speed of its trajectory.
Recreational use of SCP-677 is strictly prohibited. Note: There was a reason for that warning. –Dr. Mentha, recorded after Incident 684-0034X
Description of Event 684-0034X:
With the permission of Agent ████, Personnel 2/677 removed SCP-677 from containment and assembled it, claiming that he was “gonna break the world record for Extreme Pogo.” After donning a parachute and attaching several restraining devices between him and SCP-677, Personnel 2/677 began jumping. After eight such jumps of varying heights, SCP-677 immediately shot into the air, breaking its restraints and [DATA EXPUNGED]. Personnel 2/677 was given medical treatment and severely disciplined.

« SCP-676 | SCP-677 | SCP-678 »


Item #: SCP-678
Object Class: Safe
Special Containment Procedures: SCP-678 is to be contained in a secure lockbox on-site in a container rated for security against at least Level 2 attempted containment breaches. Guards posted to guard SCP-678 should not be aware of what they are guarding, as recovery attempts are a risk. SCP-678 poses no recognized threat of escape at this time, but if the container is ruptured or SCP-678 removed for any reason, no personnel are to make unshielded contact with SCP-678.
Description: SCP-678 is a small statuette of a sleeping angel, that displays no unusual characteristics under visual inspection. Upon unshielded physical contact with SCP-678, however, SCP-678 excises highly traumatic events from the subject's memory immediately, leaving a blank period in the subject's recollections of the past. This function is currently being evaluated for use as a new grade of amnestic, but the further effects of SCP-678 render it unsuitable for use at this time. The process of memory removal utilized by SCP-678 is damaging to the subject, however, and in the week following contact with SCP-678, the subject's mind continues to erode. This erosion does not stop, but reaches a critical point at any time from six to nine days after initial contact when the autonomous capabilities of the brain to regulate heartbeat, breathing, and other homeostatic effects is eradicated. At this point, the subject typically dies of asphyxiation. Autopsy reveals no physical damage to the brain, and the method utilized by SCP-678 is currently unknown. After an event such as this, SCP-678 alters shape, the statuette shifting to a standing position with its eyes open and teeth clenched. The next unshielded contact with SCP-678 will cause the transference of the memories initially erased to the subject currently touching SCP-678, and SCP-678 will revert to its standard form.
Subjects interviewed during the decay process describe themselves as fearful, but cannot identify the source of the fear. As their personal sense of identity disintegrates, they continue to voice a nameless terror as long as they retain the capability of speech, which is gone by the second to third day. Those informed of their impending death seem unconcerned by it, if they understand at all, instead continuing to complain of a 'problem' that they can't figure out. Staff psychologists suspect this communication issue is due to both the subject's loss of mental faculties combined with an inability to easily express the ongoing nature of the damage to the subject. After the subject's capability of speech is gone, they typically retreat to a corner when permitted to do so, clawing at their head intermittently for approximately a day before lapsing into a coma until their death.
SCP-678 was taken from a Mr. ████ ██████████ upon his apprehension by Foundation personnel. ██████████ was a "travelling chaplain" who was visiting Veteran's Administration hospitals across the eastern United States and offering counselling to any willing to speak to him. During these counselling sessions, he would encourage the subject in any of a variety of ways to come into contact with SCP-678, an item which he only handled with a pair of gloves he wore specifically for this purpose. ██████████ would wrap up his counselling session shortly afterwards and leave the hospital. Interrogation reports indicate that ██████████, a citizen of Belgium and suspected patron of Marshall, Carter, and Dark Ltd., appears to have been using the device to harvest these 'experiences' for personal amusement. ██████████ has been remanded to Psychological Ward 14 for evaluation, his termination pending background check and review of possible value to the Foundation as a bargaining tool.
Note: Nix the value check, move Mr. ██████████'s termination date up. He's a nasty piece of work, and I don't trust anyone to not try and work around any pre-release amnestics we give him. Better to just shut him up for good. - O5-██

Subject in the later stages of infection

Item #: SCP-679
Object Class: Keter
Special Containment Procedures: Samples of SCP-679 should be contained in sealed glass vials, with the temperature kept at 25 °C. Infected subjects should be kept restrained in a sterile environment. All personnel handling samples or subjects should wear class A HAZMAT suits. Any material or infected subjects removed from containment should be incinerated immediately.
To prevent potential cross contamination at no point should samples of SCP-679 and SCP-1077 be stored at the same facility.
Description: SCP-679 is a fungal infection of a previously unknown Aspergillus species. It was discovered among the local homeless population in ███████, Florida.
It is highly infectious through direct contact with the fungus, though other means of transmission have not been ruled out.
In early stages, subjects complain of entoptic phenomena. Subjects report seeing tiny bright dots moving rapidly in their field of vision. This is especially prevalent when sneezing or looking into strong blue light.
After approximately one week from initial exposure, the sclera turns black. The subject loses vision at this time, becoming entirely blind. Within a day of this, small ulcerations appear in the corners of the eyes. This causes the vitreous humor to begin leaking out, having the appearance of thick black tears.
Mycelia are also pushed through the ulcerations. Each mycelium resembles a thin white thread coated with slime, reaching as long as twenty-five centimeters. As the ulcerations widen and more of the humor leaks out, more mycelia appear.
At this stage, the eye begins to rot entirely, a process sped up by the fungus. However, it seems to protect the rest of the eye socket and the nerve, preventing infection by other pathogens in eighty to ninety percent of test subjects. By the time the eyes have gone entirely, the sockets are filled with the fungus, with a thick mass of mycelia hanging from the empty sockets. This process takes approximately two weeks from the time the ulcerations appear.
Once the eyes are completely gone, mycelia invade the sinuses, where they trigger increased mucus production, which the fungus appears to feed upon.
At this stage, the fungus becomes mobile, the individual threads gaining motility. They move around the subject's face in seemingly random patterns.
Once the fungus begins moving on its own, subjects report their vision returning. The fungus appears to have photosensitive cells, as well as a currently poorly-understood ability to interface with the optic nerve. Subjects describe normal (and in some cases improved) eyesight, except for a much wider field of vision.
However, whenever a human with apparently normal eyes enters their field of vision, subjects experience visual hallucinations (fires, dangerous animals, sudden tilts in the floor) that seem designed to drive them in the direction of the uninfected. Once they are in range, the mycelia reach out to touch the uninfected human's eyes. This appears to be a reproductive strategy for the fungus.
Curing the condition has so far been possible only in the earliest stages of infection. Once the sclera changes, the only treatment is surgical intervention and cauterization of all tissue in the socket and sinuses.
Additional test subjects to explore the lifecycle and reproduction of SCP-679 are requested.

Item #: SCP-680
Object Class: Safe
Special Containment Procedures: Because of its usefulness as a possible diagnostic tool, SCP-680 is to be kept at Containment Site-76 in Storage Locker 76-███. Additionally, to prevent accidental activation (and subsequent waiting periods) of SCP-680, the SCP must remain at least 10 meters away from all but mechanically static machinery. Use of SCP-680 on a subject must be approved by Level-3 Personnel.
Description: SCP-680-1 is a slate sculpture in the form of a human skull missing its mandible, with a mass of approximately 7.5 kg. The sculpture itself does not appear to be hollow, as all orifices have been filled with a presently-unknown black substance that rates 9.6 on the Mohs Scale of Mineral Hardness. Beyond its improbably high durability, the skull itself appears to have no particularly unusual properties. Resting on top of SCP-680-1, however, is SCP-680-2.
This (SCP-680-2) appears to be a set of mineral appraisal tools connected to a large (6 cm) eyepiece, which is in turn connected to a bronze headstrap. Among said tools are a pair of lens adjustment knobs, a series of additional magnifying glasses, a tungsten filament with no otherwise known properties, and various other devices. Craftsmanship appears to be of a late 19th-Century Germanic design, though since SCP-680 was discovered in ████, Brazil, no specific design or influences are easily named.
SCP-680-2 has no particular effect when removed from the SCP-680-1 and tested with D-Class (or other) personnel, though said test subjects describe a feeling of motion sickness and general irritability afterward. Whenever a mechanical item of sufficient complexity is placed approximately 0.5 meters in front of an assembled SCP-680, however, several of the tools on SCP-680-2 begin to move of their own accord and set themselves to a unique setting seemingly “tuned” to the object in question. Furthermore, the filament will become increasingly warm, eventually growing visibly hot. The rest of SCP-680-1 and -2 will become otherwise temporarily inert.
After a period of approximately three minutes, a series of clicks will emit from various parts of SCP-680. Four sources of clicking have been discerned:
—From both eyepiece adjusters,
—From the additional magnifiers,
—And from within SCP-680-1's right (unblocked) eye socket.
This will continue until the filament reaches a maximum temperature of ████, after which all action ceases and the skull “powers down” for a period of approximately three hours.
Studies performed on SCP-680 have revealed that the “clicks” emitted by the SCP are actually messages communicated in Morse Code describing the “studied” item's properties, including make, purported original assembler or team, function, and other items. Furthermore, particular pieces of “study” seem to come consistently from certain points of the SCP. For example:
—Statistical component inquiries such as make, model, and craftsmanship are reported by the lens adjustment knobs,
—Suggestions as to the material composition of the object are reported by the magnifiers, and
—Particularly unusual properties are reported by SCP-680-1's eye socket.
Material composition data gathered by SCP-680 appears to be largely statistical, giving a list of item materials corresponding to 80 (reported) out of the first 92 elements of the periodic table. Materials are usually given in the greatest percentage of presence, and subsequent spectral analysis of said objects usually confirm SCP-680's analysis to within 10% (with notable deviations; see Addendum 680-2).
Notes about specific make of the object studied match surprisingly precisely with objects of known origin, (such as with SCP-███, where not only the development team was named, but also the leader's name and the SCP's approximate date of creation).
“Unusual” notes made by SCP-680-1's eye socket are much less precise than the rest of the SCP's notes, and usually take on a conciliatory nature. Many times, especially with studied SCPs, the messages will be generally what has been studied, but will also give general comments that often lead to a better overall understanding of other SCPs' behavior. As such, however, much of its empirical data is either frustratingly vague or presented in a riddle.
Dr. Mentha has shaped a theory that this SCP's “general notes” do not actually come from the SCP “studying” the material at hand, but instead performs a quick survey of previously conducted research and paraphrases it. No explanation for how it obtains this information, however, has been discovered, and Dr. Mentha is reminded that he must be more explicit in said theories so that they can at least be verifiable.
Addendum 680-1: SCP-680 must be presented directly to the object to be studied. A reproduction of the object, at best, will give information on the model or display of the object in question. Similarly, holding SCP-680 to a mirror, unless said mirror has sufficiently SCP-quality characteristics, will yield no information from SCP-680.
Addendum 680-2: SCP-680 appears only to activate when presented with sufficiently mechanical objects. Biological objects elicit no response from the SCP, and if a mechanical object has biological components, SCP-680 will completely ignore those qualities. Here, “mechanical” is used to describe objects with at least ███ moving parts within its structure.

Item #: SCP-681
Object Class: Euclid
Special Containment Procedures: SCP-681 is to be contained in a row of standard pressure tanks rated to contain helium gas. All tanks are to be chained to the floor or walls of the containment room. The containment room is to be kept airtight and at near-vacuum pressures, with two Level 1 staff assigned to check for tank leakage once a week. Checks are to be made in pressure suits, and none of the gas is to be removed without clearance from Level 2 personnel. In the event of a minor leakage into the storage chamber, the room is to be temporarily flooded with normal air to force SCP-681 into collection traps in the ceiling.
Should a very large leak occur, or should SCP-681 breach the containment room, nearby personnel are to be supplied oxygen masks immediately, and the bubbles of SCP-681 forming around them are to be siphoned off.
SCP-681 can be safely placed in latex balloons without the usual concern of leakage, but no more than three average balloons worth of SCP-681 are to be removed from the containment room at any time.
Description: Discovered in a warehouse under investigation for several cases of reported death by suffocation, SCP-681 is roughly two hundred 155-cm canisters of helium gas with unusual properties. In the event of leakage in the vicinity of brainwave producing subjects, it will move towards the subject and fill airways and sinus cavities with helium gas. In enough volume, this can lead to death via suffocation.
While still in the 155-cm storage canisters, it retains some of the capacity to exert mobility, hampered by the weight of the metal container. In lighter containers, such as the few 60-cm party-sized ones collected with the main batch, SCP-681 can exert enough force to deliver a head concussion. The range of the effect is limited to roughly 30 meters, but this is highly variable.
If placed in a balloon, it will simply drift towards any thinking organisms nearby and repeatedly bump against them. Balloon animals, however, will become slightly animate and act hostile, though still largely ineffective due to being simple latex balloon animals. SCP-681 will, through unknown means, migrate into nearby balloons if it breaches containment.
Addendum:
After all this time, someone just now thought to check the serial numbers on the canisters and discovered we're missing over ███ of them? Do you people have any idea how much gas there is in one of those? -Dr. ██████

SCP-682 shortly after escaping from containment, still recovering from acid immersion.

Item #: SCP-682
Object Class: Keter
Special Containment Procedures: SCP-682 must be destroyed as soon as possible. At this time, no means available to SCP teams are capable of destroying SCP-682, only able to cause massive physical damage. SCP-682 should be contained within a 5 m x 5 m x 5 m chamber with 25 cm reinforced acid-resistant steel plate lining all inside surfaces. The containment chamber should be filled with hydrochloric acid until SCP-682 is submerged and incapacitated. Any attempts of SCP-682 to move, speak, or breach containment should be reacted to quickly and with full force as called for by the circumstances.
Personnel are forbidden to speak to SCP-682, for fear of provoking a rage-state. All unauthorized personnel attempting to communicate to SCP-682 will be restrained and removed by force.
Due to its frequent attempts at containment breach, difficulty of containment and incapacitation, and high threat of Foundation Exposure, SCP-682 is to be contained in site [REDACTED]. The Foundation will use the best of its resources to maintain all land within fifty (50) kilometers clear of human development.
Description: SCP-682 is a large, vaguely reptile-like creature of unknown origin. It appears to be extremely intelligent, and was observed to engage in complex communication with SCP-079 during their limited time of exposure. SCP-682 appears to have a hatred of all life, which has been expressed in several interviews during containment. (See Addendum 682-B).
SCP-682 has always been observed to have extremely high strength, speed, and reflexes, though exact levels vary with its form. SCP-682's physical body grows and changes very quickly, growing or decreasing in size as it consumes or sheds material. SCP-682 gains energy from anything it ingests, organic or inorganic. Digestion seems to be aided by a set of filtering gills inside of SCP-682's nostrils, which are able to remove usable matter from any liquid solution, enabling it to constantly regenerate from the acid it is contained in. SCP-682's regenerative capabilities and resilience are staggering, and SCP-682 has been seen moving and speaking with its body 87% destroyed or rotted.
In case of containment breach, SCP-682 is to be tracked and re-captured by all available Mobile Task Forces, and no teams with fewer than seven (7) members are cleared to engage it. To date (██-██-████), attempted breaches have numbered at seventeen (17), while successful breaches have numbered at six (6). (See Addendum 682-D).

Addendum 682-E: Termination Options:
Log of event 682-E18: Dr. █████ attempts to use SCP-409 on SCP-682. General ███, General ██████, and Dr. ██████████ observing.

0400: Exposure. SCP-682 began to tear at the point of contact, causing massive trauma to the area. SCP-682 requests several times to know what it has been exposed to.
0800: Crystallization begins, spreading much slower than normal.
1200: SCP-682 shows signs of extreme pain, and begins having seizures
1300: Crystallization stops at 62% conversion. Crystallized area explodes, causing massive physical trauma to SCP-682
1400: SCP-682 recovers from exposure, despite the loss of limbs and organs. SCP-682 begins regeneration, stating that it will attempt to kill and consume all staff involved in Event 682-E18.

SCP-682 appears to now be immune to SCP-409. Use of other SCP items to terminate SCP-682 must now first be tested on samples of SCP-682 before full-scale testing.
In accordance the Dr. ████████'s recommendations (see Document 27b-6), Dr. ███████ and Dr. █████ have requested permission to attempt the termination of SCP-682 using SCP-689. The request is currently pending approval from the ████████.
It has also been suggested by Dr. Gears to use SCP-182 in an attempt to communicate with SCP-682. SCP-182 has expressed reluctance, and refuses to enter the containment center of SCP-682, if at all possible.

SCP-683-2

Item #: SCP-683
Object Class: Euclid
Special Containment Procedures: SCP-683 is to be kept in a standard 8x8x5m research bay equipped with a portable gas-powered generator. SCP-683 itself is to be covered with a suitably large, opaque drop cloth to prevent inadvertent visual contact when not involved in active research. Research bay door should meet Level II hazard control rating (steel door, reinforced hinges, SCPassport keycard access with manual override) but without the standard observation window. Video surveillance is restricted to this exterior door until testing is approved for recorded viewing of SCP-683. No guards should be posted unless approved by Level 3 or higher administrative staff, again to prevent possible inadvertent visual contact. No food or drink is permitted within twenty (20) meters of the containment area. SCP-683 is currently held in research bay Zingiber-4 at Site-19 under these conditions.
Description: SCP-683 consists of two objects: SCP-683-1 and SCP-683-2. When its unique properties are activated, it will produce samples of SCP-683-3.
SCP-683-1 is a white 1953 Crosley Shelvador brand refrigerator showing moderate external wear. Internally, SCP-683-1 appears clean and well-maintained regardless of contents, results of testing procedures, or deliberate attempts to soil it. SCP-683-1's power cord terminates in an unknown plug configuration that has proven incompatible with modern outlets. Foundation electrical engineers have constructed an adapter (Inventory Control Code 19Alys-683-7) allowing SCP-683-1 to run via a standard gas-powered home generator, which is used for all testing. When supplied with electrical power, SCP-683-1 functions adequately as a refrigeration unit. SCP-683-1's unusual properties will function with or without electrical power, but when power is provided, instances of SCP-683-3 produced do not appear to decay or spoil as long as they are kept within the unit.
SCP-683-2 is a child's (age approximated at between 5 and 7 years) drawing on standard 8.5" x 11" white paper, oriented as a landscape, and affixed by unknown means to SCP-683-1's exterior. SCP-683-2 appears to have been created with pencil and felt pen, showing evidence of moderate water damage at some point in its past. The drawing depicts a mountainous exterior landscape with an anthropomorphic sun, a house, a well, a dog, various vegetation, and a central figure which appears to be wearing a chef's toque.
Any person either uttering disparaging remarks about SCP-683-2 or attempting to remove it from the surface of SCP-683-1 begins to incur damage to both internal organs and skin/musculature upon ingesting any food item. The damage manifests as the excision of tissue from various locations on the body equal in mass to the food ingested. This effect ceases once the victim has ingested .42 kilograms worth of food and an equal amount of tissue has been excised. Though observably painful, tissue is excised seemingly instantaneously following each bite of food, and has yet to strike any internal structure that would cause the death of the subject before the .42 kilogram threshold is reached. All subjects have expired within twenty-six (26) days of last excision.
Once the .42 kilogram excision of tissue is complete, a brown "lunch" style paper bag (hereafter SCP-683-3) will appear in the interior of SCP-683-1. SCP-683-3 has consistently been labeled with the name "Eric". Text appears symmetrically in capital letters printed in black ink. Writing style appears consistent with each sample of SCP-683-3. With each appearance, SCP-683-3 has contained the following:

A sandwich consisting of two (2) pieces of white bread (crusts removed) and .21 kilograms of various excised flesh and viscera. DNA analysis has confirmed it to be that of subjects who last disparaged or attempted to remove SCP-683-2
A plastic zip-top bag containing .21 kilograms of various excised flesh and viscera. DNA analysis has again confirmed it to be that of subjects who last disparaged or attempted to remove SCP-683-2
A plastic zip-top bag containing three (3) chocolate chip cookies, measuring approximately 9cm in diameter. Testing shows no abnormalities or traces of DNA
A 3" x 5" note card reading "Be a good boy today!" Ink is black and handwriting is consistent in style with the "Eric" written on SCP-683-3's exterior

Following testing, all instances of SCP-683-3 have been incinerated with no unusual effects.
SCP-683-2 cannot be removed from SCP-683-1, and all attempts to do so have resulted in the activation of SCP-683's unusual properties. Without any attempt to remove it, SCP-683-2 has been set alight and incinerated via a simple match on three (3) occasions, but has returned to the surface of SCP-683-1 within sixty-eight (68) hours each time. Despite expectations, D-Class personnel who performed the incinerations were unaffected by SCP-683.
If multiple subjects disparage or attempt to remove SCP-683-2 at one time, only the first subject to do so experiences its effects. No further subjects can be affected until production of an instance of SCP-683-3.
Subjects who fast following removal attempts or disparaging of SCP-683-2 are unaffected until they attempt to ingest food. To date, two (2) subjects have starved themselves to death without suffering any effect from SCP-683. Subjects fed intravenously following removal attempts or disparaging of SCP-683-2 have been affected as if they were consuming solid foods.
Discovery: SCP-683 was discovered in a storage unit adjacent to the home of one Yolanda ██████████ of ████████████████, Washington. A collector of vintage refrigerators and furnishings, Miss ██████████ claims to have simply found SCP-683 unattended on a street corner in late July, 19██. Her nephew, who reportedly helped her move the item, died two weeks following the move (C.O.D. on cert listed as complications from hernia). The item was brought to the Foundation's attention when an appraiser occasionally under contract with the Foundation (through front agency Sentiments of Centuries Past Ltd.) became a victim of SCP-683's effects while evaluating Miss ██████████'s "find".
When asked why she never attempted to remove SCP-683-2, Miss ██████████ replied, "It's a nice little picture, isn't it? Why take it down?"

« SCP-682 | SCP-683 | SCP-684 »


Item #: SCP-684
Object Class: Euclid
Special Containment Procedures: As SCP-684 is too large and massive to relocate, much less fully contain in any orthodox sense, HotBox procedures are in effect. If SCP-684 is judged to have expanded beyond the coordinates of [COORDINATES REDACTED], containment is said to have failed, and HotBox borders are to enact standard deterrent methodologies1.
No staff living on the surface of SCP-684 are allowed to know the true nature of SCP-684. This specific file is not to reach any observation post studying SCP-684.
Description: SCP-684 is a massive object (assumed to be a living creature) found on the seafloor of the Indian Ocean. It is irregular in shape, with the center of its mass located at approximately ██.██, -███.██. From that center mass, SCP-684 extends approximately 70 km outward, maintaining an average height above seafloor of 12 m.
The outward 'skin' of SCP-684 is dark brown, with a rough, grainy texture. There is a slight 'give' when pressure is applied to its surface. From time to time, small sections of SCP-684's surface will dimly glow a faint blue, yellow, or pink hue. These lights tend to move in the direction of SCP-684's center mass, or to six slowly-pulsating sphincters that are believed to be mouth analogues.
History: Upon discovery of SCP-684 in 19██, the Foundation attempted to place a prefabricated research outpost near SCP-684. Due to ocean currents, the post landed on the surface of SCP-684 instead. As the outpost structure was undamaged by said misplacement, O5-█ authorized the deployment of Researcher █. ██████ to the post, later dubbed Station Alpha.
Three days later, Station Alpha was seen (via long-range underwater video) being enveloped and destroyed by a localized undulation of SCP-684's mass. When a recovery mission arrived twenty-four hours later, Station Alpha was found completely intact. When entered, Researcher ██████ was interviewed as having no memory of any SCP-684 disturbance, although expressing slight annoyance that Station Alpha "hadn't yet gotten that rover I was promised". When questioned, ██████ offered up a Foundation printout, citing orders to use an underwater rover to push animal carcasses to SCP-684's sphincters.
Off-site analysis of both Researcher ██████ and sections of Station Alpha were discovered to be elaborate copies of their original selves. During this off-site analysis, Station Alpha was seen 'regrowing', complete with another copy of Researcher ██████. This 'new' copy had no memory of the earlier copy's actions or memories.
It is currently theorized that SCP-684 assimilates and reproduces stations, and their crew, for tasks related to its survival and self maintenance. Each station is capable of issuing orders to its pseudo-crew in ways that mimic the originals, so that all assimilated crewmembers treat the orders as legitimate2. These orders are phrased in such a way that the crew believes its actions are intended to 'contain' SCP-684, leading to no doubts among the assimilated crew that anything is amiss. It would seem that SCP-684 deliberately takes the effort to ensure that station crew, despite being fabricated, are kept in good mental and physical health, ignorant about their true nature or purpose.
To test and confirm said hypothesis, the Foundation has placed four more prefabricated stations on the surface of SCP-684. In short order, each of these stations and their crews (listed below) have all been assimilated and refabricated by SCP-684. Each one does not know about the others; the designations are exclusively for Foundation use.
Addendum-1: Stations
Below are the location and duties of all five stations currently placed on SCP-684. For ease of understanding, False Ordered Task is a brief synopsis of the actions each station believes the Foundation has ordered them to do in order to contain SCP-684 (or at least keep it in a stable state), and Assumed Actual Role is what the Foundation believes the station's actual role to SCP-684 is.

Underwater photograph of SCP-684-1. Size of spheres reflects approximately one week of growth. A sample of SCP-684's surface can also be seen.

Station Iota is currently the least understood station, owing to its task of harvesting SCP-684-1. SCP-684-1 takes the shape of small (2 cm to 8 cm) spheres of varying color, which bud off the skin of SCP-684. Any given nodule reaches full size in three weeks, remaining attached for a week before disconnecting from SCP-684 and being carried off by ocean currents. SCP-684-1 has been seen as a supplementary source of nutrition for the entire food pyramid surrounding SCP-684. Examination of sea life that consistently feeds on SCP-684-1 shows increases in size, general health, and overall increased fitness. Human consumption of 684-1 has not yet been approved, but many Foundation researchers believe that SCP-684 grows SCP-684-1 in way of recompense for absorbing and refabricating its 'caretakers'.

Communication Requested By: Researcher J███ H███████, Copy 9, Station Delta
Responder: Dr. ██████, Stable One
Foreword: A tear in H███████'s diving suit during an exploratory survey has left it suffering from headaches and nausea. It has requested transfer away from SCP-684 for medical treatment.
Dr. ████: H███████, old friend, we sent you down there because you kept injuring yourself on dry land, and now you want to go back? We just took down all the padding on Site-██!
Researcher H███████: (laughs weakly) Keep it up, Will. When the hell am I getting out of here? I hate being cooped up when the rest of the crew is out there.
Dr. ████: Oh, two minutes or so. (childishly laughs) I was supposed to tell you when we sent down the submersible a few hours ago, but I guess it just sort of slipped my mind.
Researcher H███████: Asshole. (coughs) I didn't even have time to pack. Remind me to beat you once the docs fix me up, okay? (There is a sound of a submersible docking in the background) See you in two hours or so, Ted. Station Alpha Out.
Conclusion: Video records show H███████-9 walking slowly to the docking platform, which opens in front of him. As the doors begin to close, the walls of the enclosure dissolve into SCP-684 around H███████-9, who is seen struggling as the doors finish closing. All of H███████-9's personal effects are dissolved and absorbed into the walls of Station Delta. Three minutes later, the docking platform doors open and H███████-10 steps out, carrying his personal belongings. Later on, other crewmen on Delta greet him warmly.

Communication Requested By: Maintenance Crewman A█████ Z███████, Copy 48, Station Alpha
Responder: [REDACTED]
Foreword: Z███████ would, on a monthly basis, use his personal-call allotment. This is the one anomalous call.

[REDACTED]: Hello?
Z███████: Hi… I'm sorry, this wasn't the voice I was expecting. Who is this?
[REDACTED]: This is the [REDACTED] residence. Who wants to know?
Z███████ : I'm A████ (beat). You better tell me who you are, because I was expecting [REDACTED]. My wife.
[REDACTED]: You fucking asshole! Do you think you get your rocks off calling people and asking for someone's dead parents? Assholes thought that was a fun thing to do after my dad died a few years back, and the day after I bury my fucking mom, you fucking ask for her? You fucking piece of shit. ((disconnection noise)).
Conclusion: After this exchange, Crewman Z███████ is seen looking at a photo of a woman and a [REDACTED] for two hours. Getting up from his chair, he proceeds to walk over to the airlock and open it, flooding the entire station. The entire station, and all crews, are dissolved and rebuilt over the course of six hours. It is not currently understood why SCP-684 made a direct contact with [REDACTED]. Each previous iteration of Crewman Z███████ made such contact attempts, but this is the only recorded time in which SCP-684 did not generate the communication 'response'. At the risk of anthropomorphizing SCP-684, we may conclude that it simply made a mistake.

Footnotes
1. There have been some in the Foundation that have expressed a belief that, given SCP-684 has not grown in size or mass since discovery, HotBox procedures are a waste of resources.
2. Double-blind experiments have concluded that without tools to detect the chemical differences, all individuals reported that SCP-684-based documents had no identifying traits which hinted at forgery.
3. Interestingly, Delta Station is the only station in which the memories of the pseudo-staff are adjusted in real-time. Once all marked locations are growing SCP-684-1, all staff members immediately forget ever having been out before. Also, despite not knowing the existence of other Stations on SCP-684, Delta crews have never scouted areas where they would be detected by other stations.

Item #: SCP-685
Object Class: Euclid
Special Containment Procedures: As SCP-685 is a geological feature, it is unable to be moved from its current location. A 20 km radius around SCP-685, designated Research Site-85, is to be kept clear of all non-indigenous or non-Foundation personnel. In addition to on-site personnel, SCP-685 is to be monitored remotely via satellite from Command-██.
Non-biological objects are to be autoclaved or immersed in 10% bleach solution for 30 minutes before being removed from the site. All other objects are to be kept under BSL-3 conditions for no less than six months. Personnel rotating off duty at Site-85 will be quarantined for one month, and subject to weekly physical examinations for the next two months afterward.
Charges of C-4 are to be placed every █ m around the circumference of SCP-685, to be armed and detonated in the event of an incoming hostile object. Should any hostile object survive the explosion, it is to be engaged by the current on-site Mobile Task Force. Containment by means of a nuclear missile launched from ████████████████ is to be used as a last resort.
Description: SCP-685 is a large pit located in a remote mountain region of ██████████, located at ██'███" S ██'███" E. It is roughly circular, with a mean diameter of 33.5 m, and appears to be a natural opening in the Earth's crust, with no signs of excavation. Roughly once every 2-5 hours, objects are observed rising out of the pit, pausing at a height of ±2 m relative to the rim of the pit before descending back into SCP-685. In the ██ years that SCP-685 has been under observation, no object dropped into the hole has emerged from it again. Descending into the pit presents a danger to any explorer, as the objects have progressively higher velocities the deeper they are observed in the pit. Despite the impossibility of this, this behavior is consistent with objects accelerated solely by gravity through an airless corridor crossing the Earth's extent. However, an investigation of area within a 100km radius of the site opposite SCP-685 revealed no topological anomalies, so even if the pit does descend past the earth's crust, it does not emerge on the other side.
The hole itself is under constant video surveillance. A list of objects dropped or released into the hole since observation began can be found in Document #685-B. Since ██ June ████, all objects greater than 10 cm in diameter emerging from SCP-685 have been tracked by a high-sensitivity RADAR system, caught by an automated robotic arm suspended over the pit, and placed in containers for study by on-site staff. Specimens cataloged in this manner include:
34% Rock debris of indeterminate origin
31% Rock debris from around the site
27% Organic debris
7% [DATA EXPUNGED]
The organic debris retrieved from the pit usually consists of [DATA EXPUNGED]. A full listing of all objects observed emerging from the SCP-685 are listed in Document #685-C; those cataloged by the automated system are cross-listed in Document #685-C-1. Additionally, a catwalk is occasionally extended across the pit to gather smaller objects which emerge from SCP-685. A report of the composition of the debris may be viewed by Level 3 or higher personnel in Document #685-D. All objects retrieved from the pit and deemed not to merit further study are returned to the pit.
Human exploration of SCP-685 has been limited to the lighted portion of the hole to reduce the incidence of injuries from collisions with objects emerging from the pit. These limited surface studies have detected no deviation in the wall of the pit from known local geographic strata. In 19██ a class D personnel was lowered to a depth of 1.75 km before being incapacitated and retrieved. Before contact was lost, subject reported that the temperature remained approximately the same for the entire descent past 30 m, and that the pit slowly widened the farther down it went. This was subsequently confirmed by an unmanned observation probe lowered on ██ November 20██, which was lowered to a depth of 9.45 km before being pulverized. It recorded a constant temperature of 12.1°C for the entire descent, and the probe's laser rangefinder detected an increase of 0.92 m per 100 m descended. Due to the likelihood that further exploration using similar methods will not be able to progress further, and that reinforced probes are unlikely to add significantly to the data known about SCP-685, further exploration of the pit is discontinued as of ██/█/20██.
Note: SCP-685 is not a disposal pit. We don't know where it goes, we don't need to be telling anyone on the other end that we're here, and we won't need our garbage boomeranging back at us years from now. -Dr. Roger
Document #685-D: Analysis of all rock debris obtained from SCP-685 reveals no anomalies, and is consistent with terrestrial origin. Analysis of the organic debris reveals that, while DNA was unable to be isolated from any sample, in roughly 63% of the samples obtained mass spectroscopy detected the pervasive presence of ██ non-canonical amino acids, including [DATA EXPUNGED]. Only a handful of known terrestrial organisms use non-canonical amino acids, and of those each only uses one.
Petri dishes with media incorporating the non-canonical amino acids was used to grow cultures taken from all objects retrieved from the pit. Organisms cultured exhibited [DATA EXPUNGED] and are resistant to all known antibiotics. To date, none have been found that survive autoclaving or incineration.
Additionally, Carbon-14 dating of the organic debris exhibiting terrestrially-normal amino acid compositions reveals that none of the debris is less than thirty-five years old. This is unsurprising in light of the dessicated hexapod corpse observed on ██ February ████ before the construction of the automated retrieval system.
