Item #: SCP-131 Object Class: Safe Special Containment Procedures: No special safety procedures are to be taken with SCP-131-A and SCP-131-B. They are free to travel about Site-19 so long as they do not attempt to enter any restricted areas or attempt to leave the facility. Casual contact with the subjects is permitted, but it is recommended that such contact be kept to a minimum to prevent the creatures from forming an attachment to personnel. Hourly tabs are to be kept on subjects at all times; failure to account for their presence at these times constitutes a level one lockdown situation. Any report of abuse or mistreatment of the subjects will result in a harsh reprimand. Description: SCP-131-A and SCP-131-B (affectionately nicknamed the "Eye Pods" by personnel) are a pair of teardrop-shaped creatures roughly 30 cm (1 ft) in height, with a single blue eye in the middle of their bodies. SCP-131-A is burnt orange in color while SCP-131-B is mustard yellow. At the base of each creature is a wheel-like protrusion which allows for locomotion, suggesting that the creatures may be biomechanical in origin. The subjects can move surprisingly fast, covering over 60 m (200 ft) in a matter of seconds. The subjects, however, lack a braking system, which has led to some rather spectacular, if not overly amusing, mishaps involving the creatures. The subjects have also shown the ability to climb sheer surfaces, and have gotten lost in the air vents on more than one occasion. The subjects seem to have the intelligence of common house cats and are insatiably curious. Most of the time they simply roll around the facility, observing personnel at work and catching peeks at other Safe class SCPs. The subjects seem to be able to communicate with each other via an untranslatable high-pitched babbling. The subjects have never been observed to blink, even in laboratories when the subjects have been videotaped for over 18 consecutive hours.

Item #: SCP-529 Object Class: Safe Special Containment Procedures: No special precautions have yet proven necessary. "Josie" is quite affectionate, and at this stage is free to move about the lower levels of the facility. Staff are not permitted to feed cheese to her - she will become distressed if not given sufficient cheese. Description: SCP-529 is a small house cat (Felis catus) with grey tabby markings. Parts of the animal to the rear of the end of the ribcage appear to be missing. The body terminates sharply as if sliced in two. In spite of this, the animal has no health problems, and moves about as if its hindquarters were still in place. For example, walking takes place as usual, and some time after feeding the animal makes motions as if to void itself of waste matter. The cross-section does not display the interior of the animal, but appears pure black to the eye, and absorbs all non-visible wavelengths of light. It is slightly yielding to the touch. Gentle stroking of this area sometimes yields a positive reaction (purring and so on) but more usually leads to the creature turning on the agent, claws at the ready. Those scratched have experienced no abnormalities. The hind regions do not appear to be invisible - a cursory examination will show that there are no hindquarters. DNA testing has shown the animal to be female.

Item #: SCP-999 Object Class: Safe Special Containment Procedures: SCP-999 is allowed to freely roam the facility should it desire to, but otherwise must stay in its pen either between 8PM-9PM for sleeping, or during emergency lockdowns for its own safety. Subject is not allowed out of its pen at night or off facility grounds at any time. Pen is to be kept clean and food replaced twice daily. All personnel are allowed inside SCP-999’s holding area, but only if they are not assigned to other tasks at the time, or if they are on break. Subject is to be played with when bored and spoken to in a calm, non-threatening tone. Description: SCP-999 appears to be a large, amorphous, gelatinous mass of translucent orange slime, weighing about 54 kg (120 lbs) with a consistency similar to that of peanut butter. Subject’s size and shape is easily malleable and can change shape at will, though when at rest, SCP-999 becomes a rounded, oblate dome roughly 2 meters wide and 1 meter in height. The surface of SCP-999 consists of a thin, transparent membrane similar to that of an animal cell roughly .5 cm thick, and is highly elastic, allowing SCP-999 to flatten portions of its body up to 2 cm thin. This surface is also hydrophobic, although SCP-999 can willfully absorb liquids. The rest of SCP-999's body is filled with a viscous orange substance of unknown chemical makeup, though it is capable of digesting organic materials with ease. Subject’s temperament is best described as playful and dog-like: when approached, SCP-999 will often react with overwhelming elation, slithering over to the nearest person and leaping upon them, “hugging” them with a pair of pseudopods while nuzzling the person’s face with a third pseudopod, all the while emitting high-pitched gurgling and cooing noises. The surface of SCP-999 emits a pleasing odor that differs with whomever it is interacting with. Recorded scents include chocolate, fresh laundry, bacon, roses, and Playdoh.

Item #: SCP-023 Object Class: Euclid Special Containment Procedures: SCP-023 is to be contained in a standard 5 x 5 m Containment Unit. SCP-023 is to be contained in a walled-off intersection of two (2) corridors at Site ██, with at least three (3) meters of space in each direction, and false doors at three (3) of the four (4) ends, in addition to the real door. Security cameras will be placed and maintained above all four (4) doors. At all times, SCP-023's eye sockets are to be filled with spherical inserts made of hard rubber. Eye inserts must be replaced as they degrade. Degradation can be monitored by measuring the brightness of the "burning" effect as observed by security footage. Brightness greater than twelve (12) candela requires that the inserts be replaced within twelve (12) hours. Eye inserts are only to be replaced individually, and only after the sun has completely set. Personnel are not to look directly into eye sockets of SCP-023 at any time. Following Incident 023-27 all reflective surfaces, including displays, monitors, and eye-wear of any sort are not permitted within 30 meters of SCP-023's cell. This includes monitors linked to security cameras within its enclosure. Security personnel posted at checkpoints outside both corridors will enforce and adhere to this measure. Experimentation involving SCP-023 has been suspended indefinitely. Description: SCP-023 is a large, sexless shaggy canine (1.5 meters at the shoulder) with black fur. It has bright orange-red eyes and prominent teeth (see Incident Report 023-26). Any time an individual makes eye contact with SCP-023, either that person or a member of their immediate family will die exactly one (1) year after eye contact is broken.

SCP-2521, also known as ●●|●●●●●|●●|●, is an infohazardous SCP that steals information about itself. When information about SCP-2521 is expressed verbally or in textual form, the entity will manifest and take the source of that information, including physical objects or even people. It cannot recognize information conveyed through symbols or pictograms, which is why its SCP file is presented in that way. Here's a breakdown: Infohazard: SCP-2521 is an infohazard, meaning that the mere act of knowing about it can trigger its manifestation and subsequent actions. Steals Information: When information about SCP-2521 is recorded or spoken, the entity appears and removes that information, including the source. This can be anything from a written document to a person speaking about it. Symbol-Aware: SCP-2521 cannot recognize or understand information presented in the form of symbols or pictures. This is why its SCP file is composed of pictograms instead of text. Not Necessarily Hostile: While its actions are disruptive and concerning, SCP-2521 is not inherently hostile. It seems to be driven by a desire to gather information about itself, and its interactions are often depicted as affectionate rather than malicious. Keter Class: Despite not being overtly hostile, SCP-2521's containment is extremely difficult due to its infohazardous nature and ability to bypass physical barriers. This leads to its classification as a Keter-level SCP.

Special Containment Procedures: All containment efforts respecting SCP-7000 are under the purview of the Emergent Threat Tactical Response Authority. Non-ETTRA personnel must refrain from containment activities directly related to this scenario. All Foundation personnel must consult ETTRA Manual LK-4 ("Don't Bet On It: Assessing Your Task's Probabilistic Variable Intensity") before undertaking their daily duties. Tasks with a Probability Index above 4.9 must not be attempted except under direct instruction from Overwatch Command, ETTRA, or supervisory personnel possessing Security Clearance Level 4+. A full manifest of known SCP-7000 effects will be propagated daily on SCiPnet, and must until further notice be consulted before experiments or operations of any kind are undertaken. SCP-7000-1 is inconsequential, and requires no containment. Description: SCP-7000 is a progressive randomization of probability factors and anomalous fortuity on the planet Earth, and potentially beyond. The effect is not total — a comprehensive karmic failure would in quick succession terminate consensus normalcy, the SCP Foundation and the human race — but instead piecemeal. Each factor is randomized to a different extent, for a different length of time, and often with a different geographical radius of effect, corresponding to no obvious logical pattern. Nevertheless, the cumulative impact of many nonsensical and high-profile outcomes to formerly predictable actions is degrading the Veil of Secrecy at an alarming rate and jeopardizing containment efforts worldwide. The cause of this disruption is, at present, unknown. SCP-7000-1 is Dr. William Wallace Wettle, a white male 54 years of age presently serving as Deputy Chair of Replication Studies at Site-43. His relationship to SCP-7000 is classified Level 4: Secret.

Item #: SCP-1013-J Object Class: Keter Special Containment Procedures: Because of the sheer size and global distribution of SCP-1013-J, containment in the strictest sense is impossible. As such, containment of SCP-1013-J consists of constant monitoring of SCP-1013-J’s activities and suppressing information about the true nature of SCP-1013-J. Any official contact with SCP-1013-J must be performed by members of Mobile Task Force Zeta-00 (“Fuzzbutts”); all other Foundation personnel are strongly advised to avoid interaction with members of SCP-1013-J. Current and former rosters of Zeta-00 are restricted to personnel with O5 clearance or equivalent. Personnel who find that they have accidentally run over a member of SCP-1013-J with their vehicle should vacate the area as quickly as possible. Personnel are strongly advised to not attempt to run over members of SCP-1013-J on purpose, as the consequences may be catastrophic to the individual in question Description: SCP-1013-J is composed of most (if not all) members of several species of genus Sciuris, mainly the eastern gray squirrel (S. carolinensis), the fox squirrel (S. niger), the red squirrel (S. vulgaris), and the western gray squirrel (S. griseus). Members of SCP-1013-J are significantly more intelligent than are widely believed, and are suspected to be carrying out a plan to take over the world from a vast underground/arboreal complex. Most details of this plan have yet to be uncovered; however, reconnaissance agents have reported widespread combat training with a variety of weaponry and martial arts.

Keter-Class Containment Proposal Brief2: SCP-3812 is to be constantly monitored by Mobile Task Force Ganymede-66 “Starlight Knights”, who are to maintain a 5km quarantined area of exclusion around SCP-3812. The acting MTF GY-66 Team Lead, in conjunction with Site-86 research staff, is allowed fiat authority in regards to any aspect of SCP-3812’s containment. Special care must be taken in order to prevent unnecessary exposure to SCP-3812. Current containment efforts focus on mitigating SCP-3812’s influence on population centers, as well as research into the full breadth of SCP-3812’s anomalous capabilities in order to establish a more comprehensive containment procedure. Information Security teams are to monitor all forms of digital media in order to prevent widespread awareness of SCP-3812. SCP-3812 has an active, aggressive, anomalous influence on reality. SCP-3812 is capable of altering events throughout time3 to prevent its containment. Due to the nature of these alterations, it is highly unlikely that any individual affected by SCP-3812’s anomalous influence will be aware that they are affected. It is highly likely that most affected individuals no longer exist as a result of SCP-3812’s influence, though any attempt to deduce how often this has happened would be speculative. Description: SCP-3812 is a reality-altering entity. Due to SCP-3812's latent effect on reality, it is nearly impossible to describe SCP-3812 in any meaningful way. All that is known about SCP-3812 is that it was once Sam Howell, a non-anomalous African-American human being, who was believed to have died in 1996. Sometime shortly after its death, SCP-3812 was observed rising out of its grave and disappearing. SCP-3812 was brought to the Foundation's attention after its presence resulted in the demolition of an apartment building in Warsaw, Poland. Due to its anomalous capabilities, SCP-3812's appearance varies significantly, making it exceedingly difficult to track.

Item #: SCP-169 Object Class: Keter Special Containment Procedures: Because of its size, SCP-169 cannot and almost certainly will never be contained—no structure on Earth is large enough or strong enough to contain SCP-169. The location of SCP-169 is not precisely known, but imaging satellites and analyses of eccentricities in the Earth's orbit suggest SCP-169 is located in the southern Atlantic Ocean, possibly stretching around the tip of South America Any satellite footage of a shift in the landmasses produced by SCP-169 is to be excised and destroyed by embedded agents. Description: SCP-169 is surmised to be a marine arthropod of enormous size, known as the "Leviathan" by generations of sailors and oral history. Presumed at first to be a myth, SCP-169 was detected on ██/██/19██ by Mobile Task Force Gamma-6 during an investigation of paranormal activity around the █████ █████████ archipelago (coordinates ██°██'S ██°██'W). During Ɣ-6's investigation, Dr. ████ ████████ [Ɣ6-0912] discovered the archipelago to have moved at least three (3) kilometers from its original location. Though initially Dr. ████████ believed this motion to be due to unusually-quick continental drift, a reconnaissance mission performed by the USS ████████ revealed the archipelago to be the protrusions of rock-like plates covering an enormous organic mass. The Foundation was brought in immediately to begin threat management. Dr. ████████ and Dr. ██████████ [Ɣ6-0421] estimate SCP-169's body length to be between 2000 and 8000 km. The creature is thought to have existed since the pre-Cambrian era. No other specimens have been sighted. Almost nothing is known about SCP-169's habits, such as its reproductive capabilities (if any), food source, and nesting area (if any). Research regarding SCP-169 is pending approval.

Item #: SCP-354 Object Class: Keter Special Containment Procedures: Due to SCP-354's immobile nature, Area-354 has been built around it. Area-354 houses forces and D-class personnel prepared to deal with threats emerging from SCP-354, as well as researchers studying SCP-354 and its properties. For their own safety, no on-site personnel are to approach SCP-354 at any time. Direct interaction with SCP-354 is permitted only for the purpose of research to eliminate SCP-354 and must be approved by O5 personnel. Area-354 was constructed to contain and neutralize any and all further threats emerging from SCP-354. At the heart of Area-354, a twenty (20) foot wall of concrete reinforced with [DATA EXPUNGED] has been constructed around SCP-354 to prevent emerging entities from escaping into the area at large. High-speed motion detection cameras are placed atop the wall looking down into the pool, and armed guards can easily shoot down into the enclosure from catwalks placed above the pool. Description: SCP-354 is a pool of red liquid discovered in northern Canada. The liquid is of a consistency similar to that of human blood (hence the colloquial name Blood Pond) but is not of a biological nature. The pool does not have definite banks; soil mixes with the liquid until, at a certain point, there is more soil than liquid and the ground is mostly solid. The liquid becomes denser as one descends deeper into the pool; if the pool has a bottom, it has yet to be reached. Periodically, entities emerge from the pool and attempt to escape from the enclosure. Thus far, nearly all creatures emerging from SCP-354 have been extremely hostile and highly dangerous. SCP-354 is believed to have been first discovered in ████ by survivors of a plane crash, who encountered SCP-354 by chance. SCP-354 had developed into a local urban legend long before Foundation personnel arrived to deal with the threat.

Special Containment Procedures: Direct physical containment of SCP-3889 is not currently possible. As of the time of this document's creation, general knowledge and influence of SCP-3889 has not extended beyond the eastern coast of the central United States of America, namely the states of Maryland, Virginia, and North Carolina, and as such current secondary containment measures are considered adequate until investigation yields a feasible mechanism for its physical containment All major piers, wharves, shipyards, harbors, marinas, and commercial fisheries in this region, including their surrounding waters extending to 5 kilometers from the coastline, will be monitored by Naval Task Force Sigma-58 “Bottomfeeders” in conjunction with Foundation naval assets for secondhand accounts of SCP-3889's exploits, as well to contain and neutralize any aftereffects of event 3889-TEHOM. Disinformation initiative 3889-WHOPPER is to be continually disseminated across social media and local news networks for the purposes of dismissing accounts of SCP-3889's activities as a series of exaggerated “fisherman's stories” or tall tales. Foundation agents are under standing orders to employ any means necessary to prevent SCP-3889 from undergoing event 3889-TEHOM. Description: SCP-3889 is Henry “Hank” McAllister, a retired independent fisherman born and primarily active in the central-eastern coastal region of the United States of America. All available records place SCP-3889's date of birth as November 27, 1849, though this fact has, for unknown reasons, not been a cause for alarm or interest for any administration within which this information is retained. SCP-3889 claims to not know its actual age, though its physical appearance is consistent with that of an average male Caucasian octogenarian. An average of 6 times per year, SCP-3889 will undergo a 3889-TEHOM event. In simple terms, 3889 fishes up a very dangerous, demonic not real fish like animal, otherwise known as SCP-3889-1.

Item #: SCP-017 Object Class: Keter Special Containment Procedures: SCP-017 is contained in an acrylic glass cage, 100 cm by 50 cm by 50 cm, centrally suspended in a concrete room measuring 6 m by 6 m by 4 m. Attached to the walls, ceiling, and floor of the room are high-intensity arc lamp spotlights pointed directly at the acrylic cage, to ensure that SCP-017 is constantly exposed to light from every angle. Personnel assigned to the SCP-017 control room are to monitor the functionality of the spotlights and the emergency generator system and call for maintenance immediately upon knowledge of a burnt-out lamp or an issue with the generator. The only circumstance under which personnel are allowed entrance is to replace lamps. Personnel entering the room are required to wear the designated full-body reflective suits, and must be cautioned not to step in front of functional spotlights. Description: SCP-017 is a humanoid figure approximately 80 centimeters in height, anatomically similar to a small child, but with no discernible identifying features. SCP-017 seems to be composed of a shadowy, smoke-like shroud. No attempt to find any object beneath the shroud has been successful, but the possibility has not been ruled out. SCP-017's reaction to shadows cast upon it is immediate and swift. SCP-017 leaps at the object casting the shadow and completely encloses it in its shroud, whereupon it returns to its normal size, Additional Notes: Personnel with BETA clearance or higher should see also document #017-1.

Item #: SCP-1128 Object Class: Euclid Special Containment Procedures: Written descriptions or imagery of SCP-1128's appearance, or videos of the entity "breaching" (see Addendum 1128-3) found outside the Foundation are to be destroyed, and class-C amnestics are to be administered to anyone exposed to such information or showing signs of SCP-1128 contamination. A written description of the entity's appearance is to be kept at Site-██ for experimental purposes only and is not to be read by anyone other than D-class used for testing. If exposed, staff are to report immediately for administration of class-C amnestics. Mobile Containment Force Kappa-12 has been assigned to intercept and redirect any and all water traffic that passes through their designated patrol area by any means necessary. Description: SCP-1128 is an entity that manifests as a massive aquatic predator to anyone given a full description of the being's appearance through either spoken/written descriptions or visual depictions of the being. Persons infected by SCP-1128 will initially exhibit no abnormal behavior, though some cases show a general aversion to activities involving bodily immersion in water such as bathing or swimming. Should subject ever be fully immersed in water, they will disappear completely under the surface of the water, regardless of the water's actual depth. In most cases, subjects will reappear moments later in a panicked state and frantically try to leave the water, while in some other cases the water will become polluted with blood and debris confirmed to be the remains of the subject. Subjects that have reappeared intact claim that they were transported to a vast ocean where they are pursued by SCP-1128. Interviews with these individuals carries some risk of further SCP-1128 contamination, as descriptions of the being's appearance trigger further infections. SCP-1128 infection can be treated with class-C amnestics.

Special Containment Procedures: All live instances of SCP-3199 are to be contained on Site-114 within a modified Keter humanoid containment chamber (hereby referred to as primary containment), the walls of which should be coated in approximately two centimeters thick acid-resistant steel. CCTV equipment is installed in the north-eastern and south-western corners. Two meters of empty space are to be allocated between primary and secondary containment. A temporary recall procedure is detailed in Addendum 3199-03. Experiments involving the use of live SCP-3199 instances are strictly prohibited without approval from at least two personnel of Level-4 security clearance or above. This block is to be at a height of at least three meters. One armed security guard is to be stationed outside primary containment at all times. An eight-digit passcode can be obtained from the current Site-114 director in order to bypass primary containment. Secondary containment is to be regularly examined for damages. Movement and activity of any kind are to be noted, and the current Site-114 Director is to be informed at the earliest possible convenience. As of 2/18/2019, there are six live instances of SCP-3199 successfully contained. Description: SCP-3199 denotes a species of sapient Category-5 biological entities of currently indeterminable origin, though tissue samples indicate the presence of Silkie chicken1, chimpanzee2, stoat3, mussel4, adder5, and human DNA. They are typically hairless, stained with a thin layer of an albumen-like excretion, and stand at an average of 2.9 meters. Its weight averages 780 kg for a matured instance, and 360 kg for a hatchling. Autopsy has determined that the cervical vertebrae of a mature SCP-3199 instance are composed of cartilage, rather than bone. This enables the neck and throat to twist and dislocate to around 340° in either direction, aiding their unusual reproductive cycle.

Item #: SCP-507 Object Class: Safe Special Containment Procedures: SCP-507 is allowed free roam of the facility, obviously barring anything that would breach security or safety protocols. Any time SCP-507 leaves its private quarters it must be accompanied by an agent, mostly at this point to make sure that it does not “shift” without the facility’s knowledge. SCP-507 should not be physically touched if there have been more than two weeks since its last “shift”; the risks inherent in disobeying this protocol make the action its own punishment, should the issue of disciplinary measures ever come up. When SCP-507 undergoes a shift, faculty will be informed to keep an eye out for its eventual reappearance. Also has a tracking device implanted into him, and a daily signal check should verify whether or not 507 has returned from its trip. If it reappears in or nearby the facility, SCP-507 will return to its quarters on its own; otherwise, a retrieval team of three plainclothes agents may be sent to provide transportation back. Upon successful return, SCP-507 can be the subject of various physical tests up until two weeks after each shift. It is worth noting that SCP-507 is allowed a computer with an Internet connection in its room, and may petition to use as a test subject for Safe or Euclid SCPs that do not affect mental functions negatively or carry an infectious trait. This is a result of SCP-507's persistently clean record, and the implication that if SCP-507 was ever going to be a security leak it would have used its faux-teleportation powers to do so already. It is also worth considering that SCP-507 is actually below-average in most physical traits. Description: SCP-507 is a Caucasian male with blond hair and green eyes, sporting no other outstanding characteristics besides being somewhat overweight and speaking with a vague accent of disputable origin. Although SCP-507 has an already-established name due to its unremarkable upbringing.

Item #: SCP-054 Object Class: Safe Special Containment Procedures: Subject is held in a watertight isolation room outfitted with specialized climate control equipment. An ornate fountain filled with water stands in the center of the enclosure. Maintenance personnel are required to wear NBC suits while inside the containment area and must spend ten minutes in a special drying room after exiting. In the event of a breach, the surrounding area should be evacuated and the enclosure flushed with liquid nitrogen. The fountain's chemical levels and volume are to be monitored and maintained. Spring water from ████████ should be used as SCP-054 is highly sensitive to hydrological conditions. SCP-054 has developed a mistrust for human males during its confinement; thus, assignment of female personnel is recommended. Description: Out of the water, the subject most often appears as a female humanoid with a mean volume of 90 L comprised entirely of water (other forms are possible, commonly geometric shapes). When it enters a body of water, it becomes indistinguishable from its surroundings. The subject must periodically return to a body of water in order to maintain its volume due to evaporation. Initially found in ████████, it was moved to Site-08 for further study. Subject was initially curious about Foundation personnel and seemed to enjoy interacting with maintenance staff and researchers, and mimicking their forms. After a number of weeks, the creature apparently felt comfortable enough to remain out of the water during routine monitoring, though it retreated when attempts were made to study its composition. SCP-054 is apparently composed of normal water, with no detectable differences compared to ordinary spring water from the same source. No thermal, electromagnetic, biological, or other phenomenon has ever been detected in its "body" that would suggest how it animates. Water lost by SCP-054 to evaporation exhibits no special properties when condensed.

Item #: SCP-165 Object Class: Keter Special Containment Procedures: Housed in a facility at Armed Bio-Containment Area-14, SCP-165 is to be treated as a contagious, pathological organism. The highest sterilization and quarantine procedures are to be followed. Microwave field generators around SCP-165's area are in place to restrict movement of its dune within its containment area. Once every nine (9) days, SCP-165 is fed live cattle weighing at least seven hundred fifty (750) kilograms. Description: The organic component of SCP-165 resembles that of typical parasitic mites, seven hundred fifty (750) micrometers in length, with eight (8) legs and a genetic structure similar to the house dust mite. The main difference is the hermit-crab-like behavior of attaching grains of sand to its back. It is unknown what purpose the sand serves, but the massive colony of SCP-165 numbers in the hundreds of billions to possibly trillions, creating a rather large dune. [DATA EXPUNGED] and SCP-165 are only superficial. [DATA EXPUNGED]'s colony is protozoan in nature and apparently shows a collective intelligence and awareness that is not understood. SCP-165's colony is made up of individual Acari who don't show cooperation but rather competition in the hunt for food. Like mosquitoes, they rely on chemical detection of carbon dioxide and sugars in the air to detect prey. The Acari mites roll and bound over one another toward prey, only using their legs to climb over one another. When in contact with the flesh of animals, they release a numbing chemical toxin in their bite, similar in make-up to that of mosquito and flea bite toxins. Subjects are typically unaware that millions of mites are 'taking turns' at grabbing mouthfuls of its flesh as they swarm around their victim. A typical swarm resembles a swirling vortex around a victim or victim's appendage.

Item #: SCP-4521 Object Class: Safe Special Containment Procedures: SCP-4521 is to be kept in Site-551's Bioterrarium and only accessible by personnel with Level 2 clearance or higher. Additionally, attempts are to be made daily in an attempt to provoke vocalizations from SCP-4521. Description: SCP-4521 is a Douglas fir tree with abnormal shape and leaves. SCP-4521 was discovered within God's Silence, Oregon after reports of an "ear piercing silence" from within the tree's vicinity. Amnestics were administered, and SCP-4521 was transported by implanted Foundation agents to Site-551. Currently, SCP-4521's anomalous property is that it is incapable of screaming. No apparatuses are found on SCP-4521 that allow it to scream, and attempting to create one has been met with failure (see testing log). Attempts are being made to provoke screaming within SCP-4521.

Item #: SCP-247 Object Class: Euclid Special Containment Procedures: SCP-247 is kept in an enclosure of at least 20 (twenty) by 40 (forty) meters, furnished based on the plans provided by the [REDACTED] Zoo and lined with SCP-148 offset from the rest of Site-██ by at least 50 (fifty) meters in order to mitigate its psychic effect. (As per current containment procedures for SCP-148, its use in the containment of other SCPs is to be avoided if at all possible. - O5-█). SCP-247 is to be fed 18 kilograms of fresh meat on a tri-weekly basis. Feeding occurs in a separate enclosure. Cleaning staff should enter the enclosure only during designated feeding times. No other access to the enclosure is allowed. The footage resulting from any violation of this order is to be archived for use in training the cleaning and monitoring staff of SCP-247. In case of a containment breach, the entire wing must be evacuated and all live footage of the incident heavily censored. The area SCP-247 occupies will be sealed off and gassed, followed by the return of SCP-247 to containment. If for any reason this should become impossible, a retrieval team will be sent in armed with heavy tranquilizer rifles. Retrieval team Agents must be specially selected for high reflexes, excellent marksmanship, unquestioning obedience, and low empathy scores. Description: SCP-247 is a Bengal tiger (Panthera tigris tigris; adult female) which, to all observers, appears to be a harmless cat (Felis catus; juvenile female) with an orange-and-black striped coat resembling that of a tiger. Remote feeds and still photos also show this illusion, although it is unknown whether the photo itself is affected or merely the observer. SCP-247's true nature has been confirmed by analysis of weight, water displacement, and dental moulds made from bite marks. 247 Is known to accept affection from its victims for upwards of 7 minutes before disemboweling and devouring them.
