Item #: SCP-241
Object Class: Safe
Special Containment Procedures: SCP-241 is to be kept at Site-19 using standard operating procedures for containing Safe-class book- and manuscript-type SCPs (see Document 241-05-3H), with the following additional conditions: SCP-241 must be kept open on a flat surface, with restraints across opposing pages of the open book to keep it from closing accidentally. Containment devices must be checked at least once a week for structural integrity. Any anomalies must be reported immediately to Site Command.
Access to SCP-241 is restricted. Any and all usage of SCP-241 must be logged. SCP-241 must be transported in an authorized bookstand such that it cannot accidentally be closed in transit.
In the event that SCP-241 is opened outside of a testing environment, the last person to have touched it must report to the nearest infirmary, and a D-class personnel must close and re-open SCP-241.
Description: SCP-241 appears as a normal book, 33 cm x 23 cm x 3.5 cm, entitled Good Home Cooking. The cover of SCP-241 is a red and white checkerboard pattern, with the title in simple black letters on the front and spine. When open, SCP-241 contains 99 recipes, sorted into typical sections of a cookbook. Many of these recipes include a picture of the dish that is invariably appetizing, and a small percentage will call for rare or exotic ingredients.
Whenever SCP-241 is opened by a subject (known as the Target) different from the one who last opened it (i.e. the previous Target), the recipes contained in the book change. Preliminary investigations concluded that if the Target eats a dish prepared from one of the recipes in SCP-241, that person soon dies from apparent anaphylactic shock. Others who eat the same dish are not similarly affected. Testing has been authorized to determine the exact nature of SCP-241's effects.
SCP-241 appears to be impervious to getting dirty and to at least minor damage. For example, sauces splashed onto its pages disappear almost immediately, and torn pages and nicks on the cover are repaired within seconds. Testing on the limits of SCP-241's durability are not authorized without approval from [DATA EXPUNGED] and [DATA EXPUNGED].
Research on SCP-241 continues, including potential interaction with other SCP items. For more information on current experimentation, please see the Supplemental Testing Log.

Directive 241-S06, ██/██/20██
In light of recent test results with SCP-241, no further testing of SCP-241 on personnel without pre-existing food allergies is authorized without Level 4 Security Clearance. Testing may continue on personnel with pre-existing food allergies as long as documentation of said allergies has been filed with [DATA EXPUNGED]. –O5-██.
Directive 241-S09, ██/██/20██
Reclassification of SCP-241 to Euclid class is denied. Honestly, the cookbook? Leave it in its room and everything's fine. It's no one else's fault if you don't know what you're allergic to and don't bother to find out beforehand. Unless you're cooking for your significant other, then you'd better know. –O5-██.
Directive 241-S11, ██/██/20██
Cross-testing SCP-241 with other SCPs will be considered on a case-by-case basis. Exposure to SCP-682 has already been considered and denied. –O5-██.

Addendum 1: Acquisition Summary

The Foundation became aware of SCP-241 in April 20██, while investigating reports of a “black widow” in ██████, ██, named ████████ █████████. Mrs. █████████ had been married four times, and all four of her husbands had died shortly after eating a meal at home. However, since authorities never found evidence of foul play, Mrs. █████████ was never charged with any crime. Subsequent interviews with Mrs. █████████ by Foundation personnel revealed the existence of SCP-241, at which time SCP-241 was seized by Foundation agents. Mrs. █████████ revealed that she had first realized there was something unusual with SCP-241 when [DATA EXPUNGED]. See document [DATA EXPUNGED] for transcripts of interviews with Mrs. █████████.

Addendum 2: Initial Testing Log

Display Initial Testing Log

All tests on SCP-241 were carried out in Test Kitchens at Site-19, using D-class personnel for test subjects, unless otherwise indicated.
Test 241-01, ██/██/20██

Subject: Subject 241-A was chosen from general population. No unusual traits selected for.
Procedure: Subject 241-A was presented SCP-241 while closed and instructed to open it, choose a recipe, prepare it, and eat it, while giving feedback during the entire process.
Results: Before exposure to SCP-241, subject declared that he had “never cooked anything more complicated than Ramen noodles.” Subject opened SCP-241, reporting nothing unusual. Subject looked through recipes in SCP-241, choosing Sautéed Scallops in a White Wine Sauce. Subject prepared the Sautéed Scallops from the recipe in SCP-241, and when complete, remarked that he did not know he could do that. Subject declared that the prepared dish smelled “fantastic”, and while eating it, declared, “This is the best thing I've ever eaten!”
Three minutes after completing the meal, subject started showing symptoms of anaphylactic shock. Subject was treated with emergency doses of epinephrine, but treatment was not effective. Subject died from anaphylactic shock six minutes afterward (later confirmed by autopsy). A subsequent examination of SCP-241 revealed that 81 of its recipes called for shellfish. SCP-241 was left open.
Analysis: Results are consistent with previous descriptions of the effects of SCP-241.

Test 241-02, ██/██/20██

Subject: Subject 241-B was chosen from general population. Subject reports no known allergies to scallops or other shellfish.
Procedure: SCP-241 was still open from Test 241-01. Subject 241-B was instructed to not close SCP-241, find the Sautéed Scallops recipe, prepare it, and eat it, while giving feedback during the entire process.
Results: Before exposure to SCP-241, subject expressed doubt that he'd be able to prepare the Sautéed Scallops recipe. After preparing the dish, subject expressed surprise that he had done so, similarly to the reaction of Subject 241-A, and said that the dish smells “pretty good”. While eating, subject declared that the dish was “pretty good” and again expressed surprise that he had cooked it. Subject did not suffer anaphylactic shock or any other adverse effect after completing the meal. Post-testing observation of subject revealed no long-term effects from eating the dish. SCP-241 was left open.
Analysis: Results are consistent with previous descriptions of the effects of SCP-241. Suspect that SCP-241 may somehow improve the cooking skill of whoever is preparing the dish.

Test 241-03, ██/██/20██

Subject: Subjects 241-C and 241-D were chosen from general population. Both subjects report no skill in cooking and no allergies to shellfish.
Procedure: SCP-241 was still open from Test 241-02. Subject 241-C was instructed to not close SCP-241, find the Sautéed Scallops recipe, and transcribe it to a standard sheet of paper. In a separate test kitchen, Subject 241-D was given the transcribed recipe and instructed to prepare and eat the dish prepared.
Results: Subject 241-C found and transcribed the recipe without incident. The transcribed recipe was visually compared to the recipe in SCP-241 and confirmed to be identical. SCP-241 was left open. Subject displayed no adverse effects from interaction with SCP-241.
Subject 241-D was given the transcribed recipe and attempted to prepare the Sautéed Scallops, but experienced difficulty and frustration, several times declaring, “I told you guys I can't cook!” The completed dish did not look or smell nearly as good as in previous tests.
Subject balked at eating the dish, saying that “it smells like ████,” but was persuaded to eat it by [DATA EXPUNGED]. Subject ate approximately 40% of the meal before stating, “I'm gonna be sick,” at which time subject vomited. Subject was instructed to finish the meal, but subject responded [DATA EXPUNGED]. Termination of subject considered but rejected in favor of further testing.
Analysis: More evidence that SCP-241 can improve the cooking skill of its user. Subject 241-D retained for further testing.

Test 241-04, ██/██/20██

Subject: Subject 241-D.
Procedure: SCP-241 was still open from Test 241-03. Subject 241-D was instructed to not close SCP-241, find the Sautéed Scallops recipe, prepare it, and eat it, while giving feedback during the entire process.
Results: Subject vociferously protested to having to eat her own cooking, but was persuaded to cooperate with the promise that subject would not have to eat the resultant dish if it turned out like in the previous test. Subject expressed skepticism but proceeded to prepare the Sautéed Scallops recipe. While cooking the dish, subject experienced none of the difficulties she experienced from the previous test, instead expressing the now-familiar surprise that her cooking was turning out so well.
The completed dish looked and smelled similar to the results of Test 241-02. Subject was not nearly as reluctant to eat the prepared dish, declaring it “not bad… not bad at all.” Subject did not appear to suffer from any adverse effects after eating the dish. During post-testing interviews, subject was asked how she was able to prepare the Sautéed Scallops during this test when the results of the previous test were so unappetizing. Subject stated that she did not know, only that once she started cooking the dish, it became perfectly clear to her how to do it. Subject did not appear to have any additional knowledge of cooking, and even had trouble remembering the cooking techniques she used in this test.
Analysis: There is now little doubt that SCP-241 can turn people who know nothing about cooking into gourmet chefs, at least for the dish that's being prepared.

Test 241-11, ██/██/20██

Subject: Subjects 241-E and 241-F were chosen from general population. Subject 241-E is known to have an allergy to peanuts. Subject 241-F has demonstrated considerable skill as a chef.
Procedure: Subject 241-E was presented SCP-241 while closed and instructed to open it and choose a recipe. Subject 241-F was then instructed to prepare the selected meal from SCP-241. The prepared dish was given to Subject 241-E, who was then asked to eat it.
Results: Subject 241-E opened SCP-241 and, while looking through the recipes offered, stated that all the recipes called for peanuts, adding, “peanuts mess me up something fierce.” Subject found a few recipes that did not include peanuts, and selected an Australian Carrot Cake. Subject 241-F prepared the Carrot Cake from SCP-241 and remarked that the finished product was better than he expected.
The cake was presented to Subject 241-E, who started eating without prompting or hesitation. Subject stated that the cake was “the best thing I've ever eaten” and ate nearly half the cake before claiming satiation. Within two minutes, subject started showing symptoms of anaphylactic shock. Subject was administered epinephrine, which was ineffective, and died four minutes later (autopsy confirmed anaphylactic shock as the cause of death).
The recipes in SCP-241 were examined, and 85 of the 99 recipes called for peanuts or peanut products, but the Australian Carrot Cake was not one of them. The Carrot Cake and seven other recipes included lupin flour; a quick search found that lupin flour can induce an anaphylactic reaction in those who suffer from peanut allergies. The remaining six recipes called for more exotic ingredients: two called for [DATA EXPUNGED], and while the other four asked for [DATA EXPUNGED], respectively.
SCP-241 remained open. The remaining half of the cake was saved for further testing.
Analysis: Reactions of Subjects 241-E and 241-F were both consistent with prior observations. The selection of recipes supports the theory that SCP-241 somehow determines the substance that the Target is most allergic to, and offers recipes to specifically induce a fatal allergic reaction in the Target. Contacted [DATA EXPUNGED] for analysis of the six “exotic” recipes.

Test 241-12, ██/██/20██

Subject: Subject 241-F, [DATA EXPUNGED]
Procedure: Subject 241-F was instructed to prepare the six dishes that contain neither peanuts nor lupin flour. The dishes were turned over to [DATA EXPUNGED] for analysis. The six recipes were transcribed and turned over to [DATA EXPUNGED].
Results: [DATA EXPUNGED]
Analysis: [DATA EXPUNGED]
Subject 241-F showed no apparent ill effects from preparing seven different dishes from SCP-241 in quick succession. Recommend retaining subject to study long-term effects of secondary (i.e. not as the Target) exposure to SCP-241.

Test 241-13, ██/██/20██

Subject: Subject 241-G was chosen from general population and is known to have an allergy to peanuts.
Procedure: Subject was instructed to eat the remaining cake from Test 241-11.
Results: Subject asked if the cake contained peanuts, and was assured that it did not. Subject stated that he didn't much like carrot cake, and was told [DATA EXPUNGED]. Subject started eating the cake, remarking that the cake was “pretty good, actually”. Subject consumed approximately 75% of the remaining cake before declaring satiation. After seven minutes, subject started showing signs of anaphylactic shock. Epinephrine was administered, and subject was stabilized. Subject eventually recovered, although recovery time was somewhat longer than expected.
Analysis: It appears that, although the recipes from SCP-241 are potentially hazardous to anyone susceptible to the allergen in question, SCP-241's recipes are most potent against the Target. Results from Tests 241-12 and 241-13 are encouraging to [DATA EXPUNGED] for [DATA EXPUNGED].

Test 241-14, ██/██/20██

Subject: Subject 241-H was chosen from general population. According to complete health screenings, subject has no food allergies.
Procedure: Subject was instructed to open SCP-241 and leave it open for analysis.
Results: Analysis of SCP-241 showed that 79 of the recipes on its pages called for chicken eggs or egg-based products. 15 of the remaining recipes called for eggs from [DATA EXPUNGED]. The other five recipes [DATA EXPUNGED]. These five recipes were transcribed by [DATA EXPUNGED] and turned over to [DATA EXPUNGED].
Subject 241-H stated that she had never experienced any problems eating eggs before. Subject was presented with one dozen hard-boiled chicken eggs and was instructed to eat them. Subject asked for salt and pepper (granted), and proceeded to eat the eggs. While eating the third egg, subject started complaining of stomach pain. Subject was instructed to continue eating, and she begrudgingly continued.
Upon ingesting her seventh egg, subject collapsed on the floor, doubled over in pain. Within 60 seconds, subject started showing signs of anaphylactic shock. Epinephrine was administered, and subject was stabilized. Subject recovered, within the expected recovery time for such an episode.
Analysis: We now have evidence that SCP-241 somehow induces or amplifies an allergy in the Target when SCP-241 is opened. This ability would explain how SCP-241 is able to cause an allergic reaction in Targets without pre-existing food allergies.

For information about subsequent and current experimentation, see the Supplemental Testing Log.

Addendum 3: Notes from Crosstesting:
To determine the effects of SCP-241's recipes on subjects that either cannot eat or do not require sustenance, approval was given to crosstest SCP-241 on SCP-1770. Upon subject opening the book, the contents were identical to before it was closed previously. This confirms results of Test 241-23 in which SCP-241 does not respond to inorganic subjects.

Item #: SCP-242
Object Class: Safe
Special Containment Procedures: SCP-242 is kept at a home located in ████████, NM procured by the Foundation on ██/██/████. The original owner was an out of state landlord who had problems keeping it rented. After retiring, he moved there, but disappeared after three days.
The home is unremarkable and is inhabited by Dr. ██████ and Dr. ██████████ who pose as a married couple with no children. The backyard is defined along its perimeter with a cinder block wall approximately 2 m high in accordance with the homes in the general vicinity. The pool is monitored at all times by a single Level 1 guard who also covers as the couple's live-in cook (human monitoring was added after Incident 242-1). Swimming or wading in the pool is strongly discouraged and any access to the pool by anyone other than Class D personnel for experimental reasons is forbidden.
Description: SCP-242 is a swimming pool approximately 4.5 m wide by 9 m long with a depth ranging from 1 m deep on both ends to 1.5 m deep in the center and a total volume of approximately 53,000 liters. It has a dual waterfall feature, an in-pool vacuum unit, and stairs on one end.
Any substance when placed into the pool will eventually be transmuted into sterile water which will remain sterile even after being removed from SCP-242 and introduced to a non-sterile environment. A sample taken from SCP-242 and poured into a container of water that had been tinted with red food coloring did not mix, but rather stayed together as a non-miscible bubble. Subsequent examination of samples shows them to be nothing more than pure, sterile water.
The length of time required for the transmutation to complete is dependent on the nature of the substance placed into SCP-242. Ordinary river water sampled from █████████, NM was completely sterilized in 7 minutes. Stagnant pond water taken from ████, NM was sterilized in 18 minutes. 50,000 liters of coal tar was converted over the course of 12 days.
While the pool contains nothing but sterile water, there is no apparent action of any of the features of the pool. Once a non-water substance is placed into the pool, the water jets and waterfall will come on even if disconnected from any power source. The pool vacuum, if attached, will also activate and drive around the bottom of the pool even through extremely viscous liquids. There is no cycling of water into or out of the filtration system. Pipes leading to the filtration system have been completely removed and shown to be empty and dry while pool contents were being sterilized.

Stagnant pond water, Time=0 min.

Stagnant pond water, Time=9 min.

Stagnant pond water, Time=16 min.

Stagnant pond water, Time=18 min.

Addendum:

Incident 242-1: On ██/██/████, during a time when the home was vacant but being monitored by a hidden video camera, a man and woman, apparently in their early 20's scaled the rear wall and gained access to SCP-242. They proceeded to undress, and go swimming along with two vinyl inflatable rafts acquired from the shed in the backyard. After the water jets came on, the female was startled and indicated she wanted to leave. The male claimed that it was just the automatic timer coming on to clean the pool, and "there was nothing to worry about". The couple continued to swim and engaged in intimate activities.
24 minutes after the jets started, the female was heard to say that the water was "really warm" and made her feel "tingly". The male agreed, and they both climbed onto their respective rafts and fell asleep holding hands.
29 minutes after the jets started, both of the rafts popped within 4 seconds of each other and the couple was again immersed completely in the water. At this time, significant frothing of the water began with a deep red color being given off from the subjects' locations. Subjects were heard to scream loudly and both attempted to exit the pool. Before exit was possible, the couple went under the surface, the frothing stopped and the pool went from red to clear approximately 48 seconds later. The decision was made to institute a live guard at the pool.
After two weeks, a story was leaked to the press that the couple had eloped to an unknown location somewhere in Mexico.

- SCP-242 Experiment #17

Abstract: What are the general properties of the water contained in SCP-242? Does the water retain any SCP like properties when removed from the location?
Proposal: Determine if the water is safe for human consumption both while in the SCP and outside of it.
Required equipment/personnel:

Two (2) titanium Atmospheric Dive Suits altered to fit the testing criteria
Two (2) Class D Personnel of like gender and race, age range to within three (3) years
One (1) food grade titanium barrel, one hundred and ninety (190) liter capacity
One (1) remotely controlled overhead crane capable of lifting twenty (20) metric tons
One (1) automated titanium siphon system
One (1) wireless communication system for separate links to and from both dive suits
One (1) home fumigation tenting unit used to create a neighborhood subterfuge

Estimated Budget: [DATA EXPUNGED]
Status: Approved (██/██/20██; Drs. ███ and ████████)
Results: Transcript attached for review. Contact Dr. ██████ for a full Lab Report.

Dr. ██████: Alright, once you've entered the dive suit, we'll lower you into the pool. All you need to do is take a drink from the metal straw by your mouth when instructed to do so.
Test Subject A: Uhhh, I can't see out of this thing. Shouldn't there be glass here? Why is it all metal?
Dr. ██████: That's classified. Just get into the dive suit please.
<sound of overhead crane followed by a loud splash>
Dr. ██████: Is the barrel full yet?
Test Subject B: Yep. All full.
Dr. ██████: Good. Remove the siphon and get into the other dive suit. You will not be placed into the pool. Just drink from the metal straw fed from the barrel when instructed to do so.
Test Subject B: So if I ain't going in the pool, why am I getting into that thing?
Dr. ██████: <sighs> Again, that is classified. We went over this in the debrief. Just do as instructed please.
<mechanical sounds>
Test Subject B: Damn it's dark in here. There's no light? How will I find the straw when I…oh…there it is.
Dr. ██████: SCP-242, Experiment 17, time zero set. Test Subject A, please take a sip from the straw and tell me what you experience.
Test Subject A: Ah…it's pretty warm. There's a weird chemical aftertaste, but it doesn't last long.
Dr. ██████: Good, thank you. Test Subject B, please take a sip from the straw and tell me what you experience.
Test Subject B: Hmm. Its cool. And…tastes like…well…nothing. It's good!
Dr. ██████: OK.
<A loud, long belch is heard, followed by laughter from Test Subject A>
Dr. ██████: Test Subject A, what is going on? Please take another sip.
Test Subject A: Wow. I've got lots of gas. Eeew! This stuff is really warm now. And it stings my mouth. How much longer is this test?
Dr. ██████: OK. Test Subject B, please take a sip.
Test Subject B: Yep. Same as before. No taste or smell at all. The water…is this water? It's cool and pleasant.
Dr. ██████: Test Subject A, please repeat the process.
Test Subject A: Ow! [REDACTED] this is really hot now! And…HEY! What the [REDACTED]?! Is that one of my fillings!? What the [REDACTED] is this [REDACTED]?!
Dr. ██████: Please just report your experience as succinctly as possible. Fillings can be replaced. Test Subject B, please repeat the process.
Test Subject B: This is boring, doc. Seems like a lot of hassle just to give us a drink of water.
Dr. ██████: Test Subject A, please repeat.
<choking and gurgling sounds>
Dr. ██████: Test Subject A, please respond.
<sound of a muffled scream followed by electrical shorting>
Dr. ██████: Test Subject B, please repeat.
Test Subject B: Ahh! Yep. Still nice.
Dr. ██████: OK. Test Subject B, we're moving to the next phase which is a full medical analysis. But you'll need to uhh…decompress…before you can exit the suit. It will take several hours, so get comfortable in there. Please take a drink every time the indicator light goes on and let me know if anything changes. Use the urination adapter as needed.
Test Subject B: Understood. Damn, that was easy!

Testing was ended due to internal electrical and subsequent structural failure of Atmospheric Dive Suit A. Retrieval was not attempted; complete loss of Atmospheric Dive Suit A occurred after approximately 15 hours.
Test Subject B was extracted after 17 hours. No physiological changes were detected. Subject B's urine was recovered and showed no extraordinary properties. Subject B has been released to the Class D Pool Group for future reuse.
The water remaining in the barrel was left to evaporate and did so within the expected time frame. No residue of any kind remained.

Note: The use of SCP-242 for possible disposal of any SCP related materials that are "difficult" to manage is being considered at this time. Contact Dr. ██████ for details and/or permission for testing.

caution

link to memo

Special Containment Procedures: SCP-243 is to be secured in the geometric center of a standard containment cell no less than 16 m x 16 m x 16 m. The cell is to be connected to an adjacent room of similar size and composition by one standard door; all exits to the cells are to be kept locked and guarded against unauthorized access.
No Eligible Group (more than 4 identical inanimate objects; see below) is permitted into the containment cell, nor any item capable of producing such a group, except as necessary for testing. Personnel entering the cell are subject to search & seizure of unauthorized multiples.
Objects animated by SCP-243 are to be removed to the adjacent room for study. Undesirable animated items are to be disposed of promptly, by incineration if appropriate. In the event that SCP-243 is applied to other SCP objects, or to other items of similar value, the "flock" is to be separated and held in standard Safe- or Euclid-class inanimate item lockers until the effects wear off.
Following Incident 243-02, bringing Eligible Groups of weapons, easily weaponized objects, or dry-cell batteries into SCP-243's containment is strictly forbidden.
Description: SCP-243 is a mass of small dry-cell batteries, all fused at their negative terminals into an ellipsoid approximately 30 cm long by 10 cm diameter. The arrangement is semi-fluid: the batteries may be rearranged by applying gentle pressure, though it is far more difficult to remove them from the central cylinder.
SCP-243's unusual properties manifest when an Eligible Group of objects is brought into its active zone, an area of indeterminate shape extending no more than 7.3 m or less than 2.5 m from the center of the item. The active zone's precise extent and shape change from minute to minute. An Eligible Group consists of 5 or more identical or nearly-identical inanimate objects: "nearly-identical" items are those that a casual observer cannot easily distinguish based on attributes other than overall color.
Eligible Group members animate when brought into the active zone, displaying unusual flexibility and powers of levitation and locomotion. They acquire a few basic instincts, including self-preservation and variously complex flocking behavior. Object flocks range from simple separation-alignment-cohesion groups, like flocks of birds or shoals of fish, to aggregates involving role specialization and formation of discrete subunits. Animated objects also, secondarily to flocking, tend to behave in ways thematically appropriate to an object of their type: umbrellas form large shades, chairs make themselves available as seating, knives seek out objects to cut, etc.
An item separated from the "flock" wanders aimlessly or searches for other flock members. Approximately 4 hours after separation, the item goes dormant and loses all apparent unusual properties; at this point, reuniting it with its group renders it animate again. 25 minutes after going dormant, it becomes permanently inanimate, losing all unusual properties and reverting to a normal object of its type. Whether intact or missing members, a flock de-animates permanently 24 ± 2 hours after initial exposure to SCP-243. Flocks displaying complex shoaling behavior frequently fuse upon de-animation into aggregates representative of that behavior.
Addendum: SCP-243 came to the Foundation's attention following a series of suspicious incidents involving █████ Animation Studios. The unusually fluid, "natural" motion depicted in the cartoons produced would not ordinarily have attracted attention, but [DATA EXPUNGED] every desk lamp in the facility [DATA EXPUNGED]. The effects wore off in the usual 24 hours. Class-A amnestics were administered to the animators involved and their families, all of whom remain under surveillance. Future █████ productions are to be monitored carefully for evidence of further interference.
Note: Compare the characters in █████ film "Knick Knack" to SCP-1507. "Further interference?"

Item #: SCP-244
Object Class: Euclid
Special Containment Procedures: When not in testing, SCP-244-1 is to be placed in a room with its own thermostat, kept at a temperature of no less than 38℃. This room must also have its own ventilation system to provide constant air circulation. SCP-244-1 will rest on top of a scale attached to an alarm, so that any abrupt changes in weight from SCP-244-1's cap's sudden removal or from SCP-244-1's displacement may be immediately detected. If the alarm goes off, SCP-244-1 is to be immediately retrieved, capped, and placed back on the scale. In the event that SCP-244-1 spends longer than four (4) hours uncapped and active before retrieval is possible, initiate Procedure 244-2123-B.
Description: SCP-244-1 is a Tunisian-style earthenware jar, made of common ceramics mixed with traces of [DATA EXPUNGED] and decorated with silver filigree. The inside of SCP-244-1 always has an internal temperature of -37℃ and a 125% humidity, regardless of external conditions; persons handling SCP-244-1 invariably describe it as cold to the touch. SCP-244-1 includes a cap of identical make and style to the jar itself.
When SCP-244-1 is uncapped, condensed water vapor will flow from its mouth. The rate at which the vapor emanates increases if SCP-244-1 is left lying on its side or suspended upside-down. This vapor is identical in composition to ice fog, with a temperature of -37℃ and 125% humidity as it exits SCP-244-1. Over time, this fog will disperse through whatever area SCP-244-1 is in, lowering ambient temperatures and raising humidity levels proportionally. The amount of time it takes for SCP-244-1 to fill an area with fog varies depending on the size of the space, the amount of moisture already in the air, and the temperature at the time SCP-244-1 is opened. If SCP-244-1 is left uncapped outside of any structure, it will still produce water vapor and lower the surrounding temperature. However, the effect may be considerably diminished, or enhanced, by the effects of the sun, wind, local topography, and/or local vegetation.
In any space where SCP-244-1 has changed the environmental temperature and humidity to -37℃ and a 125% humidity, there is a chance of encountering SCP-244-2, directly proportional to the amount of time that the area has been fogged over. SCP-244-2 is a mobile gaseous entity, visible only as a dense cloud of greyish fog. Whether it simply uses SCP-244-1's own fog as camouflage or is actually a part of said fog is still undetermined. Thermal imaging shows that SCP-244-2 is far colder than its surrounding environment. How SCP-244-2 achieves locomotion is not known, but testing and observation has made it clear that SCP-244-2 usually remains motionless unless there is a source of heat nearby. SCP-244-2 is attracted to any source of heat energy, and will move to envelop such sources. Because of SCP-244-2's own inordinately cold internal temperature, any object that comes into direct contact with it usually flash-freezes. Biological heat sources (including humans) are invariably killed by the flash-freezing effect, and mechanical or electronic devices ice over. SCP-244-2 appears to grow in size as it "consumes" thermal energy. In a sufficiently large beclouded area, there may be multiple instances of SCP-244-2.
SCP-244-2 will not attempt to consume heat sources with a temperature equal or greater than 600℃, and will actively move away from such sources if they are brought closer to it. For this reason, SCP-244-2 is easily repelled with burning wood or other combustive fuel fires. SCP-244-2 has been observed to disperse if exposed to great concentrations of heat in a short period of time.
History: SCP-244-1 was first discovered in the basement of a recently emptied Chaos Insurgency-occupied military base, where it had completely filled the basement level with ice fog and at least two manifestations of SCP-244-2. It was retrieved by Dr. Morris with the assistance of Mobile Task Force Beta-62. It is unknown whether the Chaos Insurgency had placed SCP-244-1 in the basement as some sort of diversionary tactic or if they themselves were looking for it.
Addendum: Whatever SCP-244-2 is composed of, it is certainly not normal water vapor. At those temperatures, mere water would surely become a solid, as indeed would most gases. However, taking samples of SCP-244-2's material has proven difficult, as it is both gaseous and freezes most devices applied to it. I suspect that this may be related to the [DATA EXPUNGED] in SCP-244-1, but studying that mineral has a host of problems all its own. -Dr. Morris

SCP-RPG

Hello. This is an SCP that is only describable using interactive media. I utilized RPG Maker to create this, and there are 4 endings.
Spoilers on the discussion page.
I got lots of help and testing on this. Pretty sure I dinged all the testers in the credits, but special thanks to Decibelles, TwistedGears, and Waterfire. Additionally thank you to SunnyClockwork for the beautiful artwork I used in the game.
Note: My original SCP-245 was moved to the SCP-2623 slot with specific explicit permission from the administration given the nature of the project I put into the SCP-245 slot. It should not be taken as a precedent of any kind as to permission to do any such action in the future.
Also! If you play this and spot a bug, mention it here. I'll fix it as soon as possible. I've run through this myself a hundred times or more, but I'm sure I or my testers missed something.
And I've requested that the page be locked so no one can edit it and mess with the links. If you're wondering why it's locked.
Edit: Until I was halfway through making it, I was unaware that this wouldn't run on Macs (or even that Macs can't run EXEs). Despite that, I have been told by other users that a windows emulator can run this program no problem. Suggested emulators such as "Wine" and "Bootcamp" have been mentioned.

Item #: SCP-246
Object Class: Safe
Special Containment Procedures: SCP-246 is to be kept in a wooden crate within Site-██'s secure storage. Researchers who requisition its use for experimentation are responsible for their own room arrangements. SCP-246 is otherwise not to be removed from its container, especially for recreational use.
Description: SCP-246 is a 16-millimeter film projector. When activated, SCP-246's projection lamp lights up and the reels begin turning. When the projector is pointed at a screen or other white surface, a film appears, even though SCP-246's film (hereafter referred to as SCP-246-01) does not pass in front of the projection lamp.
The film feeder has been welded shut, making any attempt to load SCP-246-01 into the second reel impossible. Requests to cut through or replace the feeder have been denied, due to the possibility of inadvertently breaking SCP-246. Examination of SCP-246-01 suggests that it is blank while inert, though high-speed photography shows images on the film when SCP-246 is in its active state. Analysis of these images is underway. When replaced with any other roll of 16 mm film, SCP-246 continues functioning as described below. After using SCP-246 with a reel other than SCP-246-01, that reel exhibits similar properties to SCP-246-01. Microspectrometer analysis of reels made blank by SCP-246-01 has shown anomalous forms of [REDACTED]. Further analysis by Foundation researchers other than Dr. ██████ is not permitted.
Despite SCP-246-01's content or lack thereof, when activated, SCP-246 projects a short film in the style of 1950s educational films.
SCP-246 seems to have a limited degree of awareness, as a female D-class subject was shown a film entitled "So You're Not Going to Live Very Long!". Shortly afterwards, she was terminated at the end of the month as per procedure. An introverted D-class subject ██████-██ (despite previous convictions for [REDACTED]) was shown "Three Easy Ways to Remove ████████", a film explaining tools and techniques for home surgery, and was subsequently terminated after his attempt to use a toothbrush as a surgical instrument. That night, Dr. ████████, employed as a surgeon before the Foundation [DATA EXPUNGED] and who had supervised ██████-██, attempted to follow the film's advice.
He was found dead the next day, ████████ and viscera scattered on the floor around him. Further experimentation resulted in the films "Digestive Systems of Woodland Creatures", "Three Handy Tips for Handling Amputation", and "Sightless Eyes: Dealing with Total Paralysis", which involved graphic descriptions of stroke victims' slow death by starvation before being found by relatives. All subjects suffered the described afflictions shortly after exposure to SCP-246.
Researchers are therefore discouraged from following SCP-246's directions, and to report any urges to activate SCP-246 to their research supervisor.

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.
It is unknown exactly how SCP-247 generates this illusion. There are two components to the illusion: first, a memetic effect that changes the perceived image of SCP-247 to that of a kitten, and second, a psychic component which radiates outward from the subject (diminishing according to the inverse square law and reaching half strength at █ meters). Any sentient being within this field comes under the impression that SCP-247 is completely harmless, regardless of prior knowledge or experience. Individuals in this field also show extreme reluctance to harm or allow others to harm SCP-247, even while being actively harmed by the subject. This psychic field can be blocked with SCP-148, or avoided by striking from well outside its effective range. The memetic effect is not blocked by SCP-148; as of yet, no one has been able to see SCP-247 as anything but a small striped cat.
Typically SCP-247 will begin to purr or mew when approached by a human. The human will remark that this is adorable, and approach to pet the subject (this has been observed even in persons who strongly dislike cats). SCP-247 has been known to accept affection from its victims for upwards of seven minutes before disemboweling and devouring them.
Genetic analysis shows slight deviation from a typical Bengal Tiger's genotype, indicating possible contamination [DATA EXPUNGED] all further breeding experiments require O5 level approval. The resulting hybrids have been designated SCP-247-1; see Experiment Log 247a-14 for more details.
Addendum 247a: A series of tests in exposing SCP-247 and the Control subjects to various non-human animals. Control testing took place in an exact replica of SCP-247's enclosure. Control A is a yellow kitten matching SCP-247's apparent size and age. Control B is a fully grown Bengal Tiger matching SCP-247's actual weight.
Experiment Log 247a-01
Date: ██/██/2010
Test Subject: A mixed-breed dog, mostly terrier. A known cat-chaser.
Control Test A: Subject immediately began barking and ran at the control, which retreated up a nearby tree.
Control Test B: Subject cowered in the corner as far from the control as possible. Control took no notice of subject.
Results: Subject ran toward SCP-247, barking loudly. At approximately five (5) meters away subject slowed to a halt and became silent. At this point, SCP-247 rolled over and made a ‘mewing' sound believed to be a sign of annoyance. The subject retreated to a far corner of the enclosure with its tail between its legs.
Notes: That was extremely odd. Further testing recommended. - Researcher S████
Approved. - O5-█
Experiment Log 247a-02i-ii
Date: ██/██/2010
Test Subject: A male tabby kitten with the same apparent age as SCP-247.
Control Test A: Subject played with the control in the manner expected of kittens.
Control Test B: Subject climbed a tree and attempted to hide itself from the control, displaying visible signs of terror.
Results (test i): Subject approached SCP-247 and mewed. SCP-247 responded in kind and played with the tabby kitten. The resulting footage is extremely odd; at one point SCP-247 lifts the subject (which appears to be the same size as SCP-247) with a single forepaw, while at another point SCP-247 lifts the subject with its mouth, clearly showing that its mouth is much larger than it appears to be. The leading researcher characterized this as adorable but remarked that it gave him “a headache.” Due to a faulty recorder, this test had to be repeated.
Results (test ii): Subject approached SCP-247 as above. SCP-247 made a deep purring sound, analogous to a growl. Subject reacted as in control test B.
Notes: This seems to indicate 247 has some degree of conscious control over its apparent appearance. - Researcher S████
Experiment Log 247a-03
Date: ██/██/2010
Test Subject: An adult male deer, a normal prey animal for a Bengal Tiger. (Control B and SCP-247 were not fed for 3 days prior to this experiment.)
Control Test A: Subject grazed. Control fell asleep two minutes into the experiment.
Control Test B: Control attacked, killed and devoured subject, which behaved normally for a deer trapped in an enclosed space with a large predator.
Results: Subject began grazing as in control test A. SCP-247 approached it calmly and killed it with a single bite to the neck, then proceeded to devour the subject. (Test was repeated without SCP-247 being forced to fast. SCP-247 completely ignored the subject for over a day before apparently becoming hungry and killing it, again with a single bite to the neck.)
Notes: SCP-247 seems to prefer humans, both as food and for entertainment. Other prey animals presented to SCP-247 were all killed in a single strike, while humans are invariably allowed to pet the SCP for some time before being killed and are sometimes mauled and ‘played' with the way a cat will play with a mouse. Furthermore, the SCP has killed every human it has had the opportunity to kill, regardless of hunger. - Researcher S████
Experiment Log 247a-08
Date: ██/██/2010
Test Subject: An adult female chimpanzee.
Control Test A: Subject and control ignored one another.
Control Test B: Subject retreated to a tree, showing some signs of unease. Control displayed some curiosity towards the subject but did not attack.
Results: Subject approached SCP-247, made noises identified as signs of affection, and began to groom SCP-247. SCP-247 allowed the subject to groom it for over an hour, then messily killed and devoured it.
Notes: This seems to be its typical reaction to unfamiliar prey animals. It seems to prefer to prey on apes with advanced social behaviour. Experiments with gorillas and other social apes have shown similar results. Essentially, SCP-247 is a large predator that has somehow adapted to take advantage of the largest available food source — humans. We should investigate all future reports of man-eating tigers in case there are more of these things. - Researcher S████
Experiment Log 247a-12
Date: ██/██/2010
Test Subject: An adult female grizzly bear.
Control Test A: Control fled up a tree in terror. Subject ignored it.
Control Test B: Subject and control acted nervously and gave one another as large a berth as possible.
Results: Initially subject and SCP-247 ignored one another. At one point subject came very close to SCP-247, resulting in SCP-247 giving a warning growl. Subject responded with hostility. Test aborted due to possible harm to SCP-247; subject tranquilized by Foundation personnel and subsequently killed by SCP-247.
Notes: Future tests involving animals potentially capable of killing or injuring a Bengal Tiger are cancelled. - Researcher S████
Experiment Log 247a-13
Date: ██/██/2010
Test Subject: An adult female Bengal Tiger
Control Test A: Control fled up a tree in terror. Subject ignored it.
Control Test B: Subject and control greeted one another, established the order of social dominance, then both fell asleep.
Results: Identical to control test B.
Notes: Interestingly, SCP-247 was the beta animal in this interaction. - Researcher S████
Experiment Log 247a-14
Date: ██/██/2010
Test Subject: An adult male Bengal Tiger
Control Test A: Control fled up a tree in terror. Subject ignored it.
Control Test B: Omitted, record of normal Bengal tiger mating behaviour substituted.
Results: As expected based on control B. [DATA EXPUNGED].
Notes: Researcher S████ has been removed from this project for lax security in his experiments, although in light of his injuries, further disciplinary measures have been deemed unnecessary. [DATA EXPUNGED], which seems to have benefited from a form of ‘hybrid vigor', has been designated SCP-247-1. Considering that SCP-247 is likely to have bred naturally in the wild, Mobile Task Force Iota-5 ("Tiger Bait") has been formed and assigned to hunt down and contain or destroy all incidences of the hybrid SCP-247-1. - O5-█

Item #: SCP-248
Object Class: Safe
Special Containment Procedures: SCP-248 is to be kept in a fire-proof safe in Dr. Mize's office unless being used directly for testing purposes. The safe has a keypad-style opening mechanism. Any personnel of at least Level 2 Security Clearance have full permission to access SCP-248, as the numeric code is [REDACTED].
Description: SCP-248 is a twenty-five (25) page booklet of stickers, each reading "110%" with a small pressed imprint of the words "The Factory" in the bottom right corner. The booklet itself is 7.5 cm in height and 15 cm in length. Each page of SCP-248 contains two (2) of the stickers, making a total of what would be fifty (50), but circumstances before its discovery have left only forty-nine (49) stickers.
SCP-248 was discovered at a small house in ████████, Georgia. The object came to the Foundation's attention after one (1) of the stickers was placed on an old, half disassembled tractor in the family's barn by the youngest son, Ronnie ████. The tractor was suddenly able to operate as if it were fully functional, despite lacking much of the engine and frame. Agents removed SCP-248 and the tractor from the family in exchange for a bogus coupon for free pesticides for the farm. The family was administered standard Class A amnestics.
Dr. Mize received SCP-248 upon its arrival to Site-██ and took deep interest in its apparent abilities. The tractor is now labeled SCP-248-1. See Addendum 248-01 for testing of SCP-248-1.
Testing of SCP-248 has been approved by Dr. Mize. See Addendum-248-02 and below for preliminary tests.
Remaining stickers in SCP-248: forty-six (46).
Addendum-248-01:
SCP-248-1 is a 1979 John Deere tractor in an extremely rusted state. Most of the engine is missing, apparently from a restoration that was never completed. The frame is also partially missing near the rear of the tractor where the driver would be positioned. A sticker from SCP-248 is located near the back behind the left wheel. Upon turning the key to the ignition, SCP-248-1 starts up and operates as if it were in pristine condition. It is capable of achieving speeds up to 42 km/h, slightly faster than a typical tractor of that specific model. Though the tractor operates with no engine, gasoline is still required to maintain power. Further testing is required to understand whether or not the tractor would operate without a gas tank.
Removal of the gas tank resulted in SCP-248-1 becoming non-functional in all aspects. The whole of SCP-248-1 is to be held in hangar ██ of Site-██ for future tests regarding the need for fuel, but lack of engine to create forward motion.
Addendum-248-02:
Testing of SCP-248 on a ██████ brand computer. A sticker from SCP-248 was placed on the motherboard of the computer, which was then started up like usual. The speed of the computer was greatly enhanced, as noted by Dr. ███ █████████, the owner of the computer. Diagnostics of the PC reveal the disc space to have increased from its maximum of 250 GB to 275 GB, as expected. The RAM had also reached the expected 110% efficiency. However, the interior was also experiencing similar results; the heat sink was pulling off 10% more heat than usual, and the conductivity of the wiring was allowing electricity to flow 10% more smoothly than the best modern superconductors. Why the wiring is achieving such a high rate of non-resistant flow, compared to the heat sinks slightly above-optimal cooling, is not understood at this time. Removal of the battery rendered the computer useless, just as in Addendum-248-01. Further study of SCP-248 and power supplies has been noted for future tests.
Dr. ███ █████████'s computer is now labeled SCP-248-2 and is to be kept in Dr. Mize's top desk drawer. The drawer is opened via numeric keyboard, the password to which is [REDACTED].
Dr. Mize has requested that future tests regarding electronics attempt to focus, at least partially, on the implications of this high conductivity. Some form of electricity producing turbine or power plant could potentially increase energy production a thousandfold.
Addendum-248-03:
Testing of SCP-248 on organic matter. A sticker from SCP-248 was placed on the forearm of a Class D who volunteered to work with this unknown SCP rather than being transferred to Site-19 for Keter duty. Initial reaction to the sticker yielded no results. Subject received none of the additional enhancements as seen in previous tests. After 60 minutes of exposure the subject was still unchanged. Retrieval of the sticker was ordered to test the item's adhesive properties. Agent had difficulty removing the sticker, while the subject was claiming to experience extreme pain during the attempted retrieval. After a small talk with Dr. Mize, Agent █████ removed the sticker with much of the subject's skin still stuck to it. Microscopic examination revealed that the resin had bonded to the subject's flesh in the same way Navy grade tape bonds to the sides of submarines to withstand tremendous pressures. Chemical testing of the resin itself shows that it is consistent with average, mass-produced resin used in everyday Scotch tape.
The chunk of skin was labeled SCP-248-3 by Dr. Mize and is now held in a vacuum-sealed plastic container. It is stored in the same fire-proof safe as SCP-248, in Dr. Mize's office.
Addendum-248-04:
Testing of SCP-248 on SCP-248-1; attempted removal of sticker. Agent █████ asked to try and remove the sticker with his fingers. After a few moments of failed attempts at scratching it off, Agent █████ is given tools to use: tweezers, a pair of pliers, a pocketknife, a chisel, and a hunting knife had no effect on the sticker itself. This test, along with test 248-03, confirm that the adhesive has properties beyond our understanding.
After failing to remove the sticker, a second sticker was added near the first to test if SCP-248 has "stack-able" abilities. The first speed trial observed SCP-248-1 reaching 84 km/h, which is indeed 220%. However, after a 15-minute period, the tractor showed advanced signs of oxidation wear. After a total of 36 minutes of use with both stickers, SCP-248-1 had almost completely turned to rust and lost all form. At this point the stickers fell free from the pile of rust and were gathered by Dr. Mize for testing.
Results show that the resin had formed a chemical bond, as with the biological matter, and only broke that bond after the original composition of the matter it was attached to had changed. It should be noted that there is no longer resin on the stickers and they no longer stick to surfaces. SCP-248-1 neutralized.
-If this item was mass-produced, like it is assumed that other "Factory" SCPs were, we could have potentially struck gold! If a power grid can be made to function without the degenerative effects of SCP-248, free-flowing power could be possible at room temperature! I will personally begin researching "The Factory" and its whereabouts as soon as High Command approves.
-Dr. Mize

Item #: SCP-249
Object Class: Euclid
Special Containment Procedure: SCP-249 is affixed to a wall within Site-██. Access to SCP-249 is unrestricted, though an accurate log of destinations must be kept and submitted to a Level-4 supervisor every four (4) weeks. No SCPs of any class may be brought or kept within one thousand (1000) meters of SCP-249 without Level-4 approval.
Description: SCP-249 appears to be a windowless door, covered in a faded white paint. It was first found in a house located within the small town of ██████. When opened, SCP-249 does not lead to the other side of the doorway, but to a random door within eight hundred and fifty (850) meters. Items that go through SCP-249 are teleported to that other door, regardless of what may be between the door and SCP-249. When observed from the destination, the exit door appears to open on its own accord, and whatever goes through SCP-249 appears out of thin air. When opened, SCP-249 takes on the appearance of the door it is connected to. When shut, SCP-249 is no longer connected to that door, and reverts to its standard appearance.
However, roughly every five hundred (500) uses, SCP-249 does not connect to a door within its range, but instead to a random location anywhere in the world, even locations with no apparent doors within hundreds of kilometers. When the 500-use mark approaches, common use of SCP-249 is stopped and tests are done to record its exit location. Since its discovery, a log has been kept documenting these cases (See Addendum 249-001).
Document 249-A
In accordance to O5-██, all restrooms have been moved away from SCP-249's range.
Addendum 249-001 Teleportation log.
12-10-19██: SCP-249 is found and moved to Site ██.
24-6-19██: Agent █████ goes missing and is found weeks later in eastern Canada; describes random transportation.

SCP-250, taken before capture.

Item #: SCP-250
Object Class: Euclid
Special Containment Procedures: SCP-250 is to be kept in a 50-meter-by-50-meter enclosure simulating a prairie environment, with padded steel walls 15 m high and 1 m thick. The temperature must remain between 20 and 28 degrees Celsius by day, and between 10 and 14 degrees Celsius by night, with an average humidity of no more than 8%; this serves the dual purpose of ensuring that SCP-250's overall behavior remains predictable, and of maintaining the physical integrity of its component parts. Vegetation within the enclosure is to be maintained on a weekly basis; see document 250-MB48 for details.
Although SCP-250 does not physically require nutrition, it is to be fed one live adult pig every two (2) days in order to regulate its aggression and hunting instincts. The remnants of its meal are to be removed from its enclosure no less than one (1) hour after the onset of its nightly dormancy period; this includes cleaning any residual biological debris from SCP-250's physical components with compressed air and whisk brooms. At no point during cleaning are any of SCP-250's physical components to be moved by more than 1 meter in any direction, as this risks disrupting its dormancy. Dormancy ends within five minutes of sunrise; access to SCP-250's containment during its activity period is prohibited.
Description: SCP-250 is the animate fossil skeleton of an allosaur (originally identified as Allosaurus fragilis; however, an incomplete scientific article found in the personal effects of paleontologist Dr █████████ indicates that this classification may have been erroneous). It consists of 153 disarticulated bones, and 14 plaster-and-fiberglass replacements, held together and animated by an unknown force. Study of this force is hindered by SCP-250's aggressive behavior, which has been assessed by Foundation palaeozoologists as being well within theoretical norms for an allosaurus.
SCP-250 emulates what are presumed to have been the standard daily activities of a living allosaurus: it wanders its enclosure by day, enters a state of dormancy by night, and will attempt to kill and devour anything which it perceives as suitable prey, including humans. Its lack of organs does not seem to affect its behavior in any way, except in that the remains of any prey it consumes will inevitably fall out of the gaps in its skull, neck, and ribcage, at which point it ignores them.
SCP-250 was first excavated as an 80%-complete skeleton in [REDACTED], 19██ ; records from the excavation do not include any report of anomalies. In 19██ , it was transferred to the ████████ Museum of █████████████ in [REDACTED], where it was assembled, mounted, and put on display.
On the night of ██/██/20██, SCP-250 seized and killed an intruder to the museum. Although damage to the intruder's remains was so extensive as to render forensic identification impractical, they were conclusively shown to not be those of paleontologist Dr █████████, whose office in the museum was extensively vandalized that night and who has not been seen since. Foundation personnel embedded within museum staff reported the incident, and SCP-250 was taken into custody.

« SCP-249 | SCP-250 | SCP-251 »


Item #: SCP-251
Object Class: Euclid
Special Containment Procedures: SCP-251 is to be kept in a locked container at all times. No one is to enter the container alone. If anyone is found to have been left alone in the container for any amount of time, they are to be treated as violently hostile and terminated with extreme prejudice.
The container is to be guarded by armed personnel at all times and guards should never allow anyone, regardless of clearance level, to move the artifact or be alone with it.
Sounds of screaming, gunfire, and fires will be heard from within the container. This is normal.
Description: Origin unknown. SCP-251 consistently appears to be a small snow globe. Attached is a series of photographs taken of the same artifact over time. This indicates that the snow globe is at least partially animate. However, when viewed directly by multiple people, there is no apparent movement except by a perpetual "blizzard". SCP-251 has not been moved since its arrival at Site-19, but the "snowflakes" have never ceased falling.
The scenes depicted in SCP-251 are all extremely violent or morbid, occasionally depicting something fantastical, while mostly depicting more realistic brutality.
All those who have been alone with SCP-251 for any amount of time have later displayed extreme violence, xenophobia, and emotional distress.

« SCP-250 | SCP-251 | SCP-252 »


Item #: SCP-252
Object Class: Euclid Safe
Special Containment Procedures: SCP-252 is to be contained in a 150 m3 aquarium, reinforced with high tensile steel plating. Guards are to be specially trained in water-borne combat techniques and armed with model-B74H harpoon rifles with high-capacity electrical discharge shafts. The tank is fitted with 15 remotely-activated depth charges, which are to be detonated simultaneously if a containment breach is imminent A breeding pair is maintained under the direction of marine biologist Dr. ███████. Personnel should not approach the containment tank unless they have been previously prepared for the anomalous effects of the animals.
Additional specimens of SCP-252 may exist in the wild. Due to their destructive capabilities, capture is deemed a high priority. Given the difficulties inherent in the size of specimens, termination is authorized if a breach of secrecy is imminent. Current specimens are considered sufficient and further acquisitions are not a priority. Containment of information regarding encounters will consist of Standard Cover Story 53 "Drunken Sailor" and administration of amnestics as necessary.
Description: SCP-252 is a sub-species of Dosidicus gigas. Mature specimens are noticeably smaller than average, reaching no more than 1 m in length and weighing a maximum of 40 kg. Dissection shows the absence of an ink sac and an increased density of chromatophores (approx. 20 times the normal adult average).
Behavior is identical in most ways to mundane specimens, except when hunting or threatened. When a member of SCP-252 detects prey, they exhibit aggressive behavior and move towards the target at maximum speed while rapidly cycling their chromatophores. This color shifting has a hypnotic effect on prey animals that make visual contact, causing them to cease all defensive behavior and attempts to flee until grappled.
When threatened by a predator or otherwise agitated, SCP-252 rapidly metamorphs into an unidentified aquatic life form of extreme size with an indeterminate physiology and extremely destructive demeanor. Physical attributes in this state are in a constant state of change. Size fluctuates between 50 and 75 meters in length with no fewer than 50 and occasionally as many as 200 appendages of various natures. Appendages shift constantly between suckered tentacles averaging 5 m in length, insectoid limbs terminating in barbed pincers, and humanoid arms and legs ending in sharpened talons. Details and positions of appendages on the body also vary randomly, with the only constant being a cluster of tentacles around the head obscuring the mouth area. It is not currently known how this rapid growth is achieved. Due to the potential for a containment breach no research on the matter is currently authorized. All animal life excluding other SCP-252 and mundane squid species will attempt to escape the vicinity by the most direct route possible. This fear response can cause the targets to harm themselves as they flee into hazardous conditions or ram repeatedly into container walls. Roughly 95% of subjects encountering an enraged SCP-252 develop a phobia of cephalopods. It is not known if this is an additional anomalous effect or a normal behavioral reaction to traumatic experiences.
Upon review of security footage during containment, Dr. ███████ has determined that SCP-252's "metamorphosis" is in fact an advanced hallucination induced by the shifting pattern of chromatophores. These hallucinations cause the victim to see SCP-252 as a titanic sea creature with an excessively large number of tentacles. Specific details vary greatly from subject to subject, but the hallucinatory creature consistently presents as a greatly exaggerated cephalopod with tentacles clustered around the mouth area, additional appendages with talons or pincers, and the general impression that all features are fluid and randomly shifting. Subjects removed from visual contact with SCP-252 will remain convinced that their hallucinations were a real "sea monster" and will attempt to rationalize any logical contradictions inherent in their delusion, such as a 100 m monster swimming in a 10 m enclosed tank. This rationalization and the lingering phobia is thought to be a form of post-hypnotic suggestion.
Subjects viewing video of agitated SCP-252 who have never been exposed directly experience a much less severe fear reaction and are able to perceive the squid despite the hallucinations. Subjects describe the illusory monster as "fake-looking" and "nonsensical" but still find it moderately frightening. After second-hand exposure, subjects develop a partial immunity to the full effects of direct exposure. Repeated direct contact after "inoculation" by video further lessens the effects. Acclimatized subjects can develop a complete immunity to the fear effect and experience only the vaguest awareness of the hallucinations.
Addendum: SCP-252 came to Foundation attention after numerous reports of "sea monster" sightings by commercial fishermen off the coast of █████. Agent ██████ secured a specimen at greater than usual personal danger. Commendation for performance above and beyond the call of duty recommended. Agent ██████ allowed himself to be exposed to SCP-252's effects during first contact. Initial containment procedures were based on his reports of the specimen's size and physical capabilities, resulting in an excessive expenditure of resources. Disciplinary action recommended, pending oversight review.

Item #: SCP-253
Object Class: Euclid
Special Containment Procedures: At this time, SCP-253 poses a substantial threat to humanity. SCP-253 is to be kept under Biosafety Level-4 protocols at all times. All research is to be conducted at a site where incineration and irradiation protocols can be swiftly enacted, that is geographically isolated, and does not possess a diverse biosphere. The sterilization protocols shall be enacted following the occurrence of any event on this list:

Communications blackout lasting longer than forty-eight (48) hours.
Power disruption lasting longer than one (1) minute during any active experiments involving SCP-253.
Abnormal rise in average temperatures beyond a change of 6 degrees Celsius (11 degrees Fahrenheit) or rise in humidity levels to 90% relative humidity.
Manifestations of unusual electromagnetic phenomena during testing of SCP-253.

At the conclusion of testing, any subjects exposed to SCP-253 are to be disposed of, and their remains are subject to the sterilization protocol.
Any researcher leaving the facility is to undergo two weeks of mandatory chemotherapy, followed by a 15-day quarantine.
Description: SCP-253 is a cluster of undifferentiated human cells, matching the physiological traits of cancer. As per cancerous cells, cultured samples of SCP-253 will grow indefinitely if given an adequate source of nutrition. SCP-253 is contagious, able to pass from human to human, as well as to some animal species. SCP-253 is not an airborne contagion, but physical contact with surface neoplasms on infected subjects will spread the plague.
The first sign of SCP-253 infection is the emergence of skin lesions, typically dime-sized (2 cm in diameter) in groups of three to five, at the site of infection. Within twelve (12) hours after the appearance of the lesions, MRI scans show the development of neoplasms within the brain. At this time, the neoplasms do not induce neurological symptoms.
Over the next twenty-four to forty-eight (24 to 48) hours, numerous skin lesions start to emerge and grow in size. These lesions often induce substantial swelling in surrounding tissue, which can be quite painful for the subject. Often, the pain, if left untreated, leaves many subjects unable to move. Towards the end of the forty-eight (48) hour period, neoplasms start to emerge in the lymphatic system and neurological symptoms start to manifest.
The neurological symptoms of SCP-253 are different for each patient, depending on which part of the brain the invasive cells have contaminated, with one exception. Each human patient heretofore exposed to SCP-253 has felt a complete cessation of pain forty-seven to forty-nine (47 to 49) hours after infection. Other neurological symptoms include:

Inability to focus attention
Disorganized speech
Memory loss
Hallucinations
Euphoria
Megalomania
Inappropriate emotional responses
Sociopathy
Catatonia

The neoplasms do not seem to respond to radiation, and chemotherapy with high-dose mitoxantrone, irinotecan, and dacarbazine has only minimal effects. Chemotherapy was observed to kill some cells and markedly slow the growth of others, and therefore might be useful for post-exposure prophylaxis, but is ineffective in established disease.
If the mass of cancerous cells within a population does not reach a biomass threshold of approximately one-thousand four-hundred kilograms (1400 kg/3100 lbs), the cells will overwhelm the host within five (5) days, resulting in death. If not transferred to a new host, the cancer cells will consume any remaining usable biomass of the host's corpse before finally running out of resources and dying.
However, if the mass of cancer cells within a population reaches the threshold, electromagnetic phenomena will start to manifest. The sources of these phenomena appear to be the infected hosts, but the mechanism of the EM manipulation is not understood at this time.
Furthermore, it appears the EM emanations facilitate some sort of communication between the hosts. Coordinated in some fashion by the neoplasms, the hosts start to act as one entity spread through many bodies. The intelligence of this entity is initially animalistic and reactive. As the intelligence of the gestalt entity is believed to be based on the remaining brain tissue within the hosts, it is hypothesized that the entity may be able to achieve human-like intelligence. The events from Incident I.J77.82 appear to support this hypothesis, and research suggests that some of the more unsettling things seen at ██████████████ Hospital are manifestations of this intellect.
Until suitable methods can be created to jam the EM transmissions of the end-stage infection entity, and until efficacious treatment alternatives for the diseases known as cancer enters common usage, the utmost care must be taken with samples of SCP-253.

Addenda:
253a: Proposal that SCP-253 be classified as Euclid is pending review of Incident I.J77.82 by the Overseers.
253b: SCP-253 has been given provisional Euclid classification. Final report on Incident I.J77.82 has been released. Research into the events of Incident I.J77.82 has been approved.
253c: Research involving approaching the threshold biomass in human subjects has been denied. Decision on request to test threshold biomass in cultured samples pending.
253d: Use of SCP-500 in experiments with SCP-253 has been denied.
253e: Use of SCP-427 in experiments with SCP-253 have been approved. Early results are not encouraging. Despite success using 427 to treat other forms of cancer, in this instance, 427 appears to induce accelerated growth in both tumorous growths as well as in the patient. Subjects were terminated as they neared the critical threshold for use with 427. Request to take patients beyond the critical threshold is pending.

« SCP-252 | SCP-253 | SCP-254 »


Item #: SCP-254
Object Class: Safe
Special Containment Procedures: SCP-254 is to be kept in a standard storage locker when not in use. When in storage, it must be placed face-down on the floor of the locker and secured with straps to prevent accidental activation. Use of SCP-254 may be requested by any department head, and must be approved by at least two (2) level-3 personnel. SCP-254 may not be used in a capacity that will result in SCP-254-1's contact with SCPs posing a memetic contagion hazard. Under no circumstances is SCP-254 to be active in a single department or area for longer than twenty-six (26) days. Reuse is permitted only if the area in question has undergone a complete personnel rotation (i.e. no employees remain who have had previous contact with SCP-254).
Description: SCP-254 is a rectangular wooden plaque measuring 22 cm x 30 cm and weighing approximately 1.5 kg. On the front of the plaque is an empty brass picture holder, as well as a printed metal plate with a black background and gold-colored letters reading “Employee of the Month.” Affixed to the back of the plaque is a standard hanging device.
SCP-254 was discovered in the rubble of a Texaco gas station in ██████, Kansas, on ██/██/195█. A Foundation agent secured SCP-254 after discovering that it had sustained no damage in the explosion that had leveled the gas station and resulted in the deaths of █ employees and ██ civilians .
When SCP-254 is hung on a wall in a work area of 4 or more people, SCP-254-1 will appear soon afterward. SCP-254-1 will arrive either at the end of the next designated break period, or at the beginning of the following work shift. SCP-254-1 is an incorporeal human of variable gender, age, race, name, and appearance, able to manipulate objects in the manner similar to that of a normal human of average strength and coordination. SCP-254-1 will adopt the appearance and persona of a model employee, based on an area's memetic consensus. Once SCP-254-1's appearance has been established, an image of SCP-254-1 that appears to be an 8 x 10 glossy photograph fills the empty picture holder, and it will not change until SCP-254 is moved to a new location. Across the bottom of the photograph, in print, is the newly assumed name of SCP-254-1. The photograph cannot be removed from the picture holder by any known means, but it can be torn or ripped. Doing so in an aggressive or purposeful manner results in a violent reaction from SCP-254-1 (see attached recording SCP-254-a: [DATA EXPUNGED] the ██/██/████ incident).
Regardless of appearance, SCP-254-1 maintains a cheerful demeanor at all times. SCP-254-1 is able to carry on conversations about the weather, traffic, the previous night's TV shows, sports, and other such topics, although SCP-254-1 will never discuss topics of which present individuals have no knowledge. Personnel assigned to work in an area where SCP-254 is in use do not appear alarmed by SCP-254-1's incorporeal nature or sudden appearance, stating that SCP-254-1 “works here.” Due to local personnel's reluctance to remove the plaque, or inability to remember to remove the plaque, removal is to be scheduled and performed by off-site personnel.
SCP-254-1 is capable of performing menial tasks quickly and efficiently. When given tasks that require specialized training, although SCP-254-1 does not possess the required expertise, (s)he will attempt them with the usual good attitude, but will perform as well as an average person could be expected to perform. SCP-254-1 will continue to perform as exemplary an employee as possible for a length of time between 28-46 work days, usually ending at the conclusion of a calendar month. If SCP-254 is placed in a workplace several days into a calendar month, SCP-254-1 will act as an effective employee until the end of the following month, although due to the dangers posed by shifting memetic consensus, no use of SCP-254 for longer than 26 days is permitted.
After the “month” has passed, if SCP-254 is not removed, SCP-254-1 will begin to degrade in performance, beginning with an unhelpful attitude and forgetfulness. If SCP-254 is not removed, SCP-254-1 will become a worse and worse employee until “fired.” Firing can be represented by removing SCP-254 from the wall, or by informing SCP-254-1 of its termination. If SCP-254-1 is fired within approximately 20 days from the start of its decline in performance, SCP-254-1 simply leaves the area and disappears. Following cessation of employment after this point, SCP-254-1 will actively sabotage the work area in the most destructive manner possible, posing severe hazard to any nearby personnel.
And the WORLD, people. We work with SCPs here, and if proper removal arrangements are not made with off-site security and documented with on-site security, the offending employee will find themselves jobless or worse. -O5-█
Addendum: Following Incident 254-0210g, all tests on employing SCP-254-1 beyond 26 days must be conducted at a separate site containing no other SCPs. NO EXCEPTIONS. -O5-█
Audio Log 254-a13:

Dr. █████: “This is Doctor [REDACTED]. This is experiment #13 on SCP-254. I am using a standard phillips-head screwdriver, to attempt to remove the brass fitting from SCP-254.”
[There are 15 seconds of tool-working sounds.]
“It appears that these screws are affixed by means beyond the normal. Perhaps glue, or something else.”
SCP-254-1 (going by “Gus” this iteration): “Would you like me to get you some solvent, sir?”
Dr. █████: “No thanks, Gus, no need. Would you hand me that box cutter? I'll try cutting this picture out.”
Gus: “Really? Why would ya wanna do that? I think that plaque looks jim-dandy right where it is.”
Dr. █████: “Now now. This isn't an insult to you, Gus, you're a great employee. This is an experiment.”
Gus: “Okay, Doc, I trust ya.”
[There is a slight paper ripping noise.]
Gus: “Whacha doin' Doc? Would ya please not do that?”
Dr. █████: “Just a little bit fur-”
[The audio of the two cuts out, and there are 5 hard banging sounds - presumably SCP-254-1 slamming Dr. █████'s head against the table. Then there is a wet sound as the box cutter is [DATA EXPUNGED].]

Experiment Log 254-b: Testing on extended employment of SCP-254-1 as a janitor at Sector-██.

Day 26: End of standard employment period reached. SCP-254-1's performance continues to meet high standards.
Day 32: First sign of performance degradation noted. SCP-254-1 leaves a dirty rag on Research Assistant █████'s desk. Apologetic when rag is noticed and returned.
Day 34: SCP-254-1 is mopping the floor in Sector-███ when a hurrying technician trips over the bucket of cleaning solution. SCP-254-1 recorded cursing at the technician.
Day 35: End of the calendar month. SCP-254-1 described as “sullen” by a late-working researcher. Break room kitchen in Sector-███ left uncleaned, coffee spilled around Dr. █████'s garbage can.
Day 36: SCP-254-1 reprimanded by supervisor for apparent drunkenness. (Note: Very odd; SCP-254-1 has never been seen to eat or drink.)
Day 39: SCP-254-1 fails to return cleaning solutions to the janitorial closet. Near-disaster when mentally disturbed test subject (see Experiment Log [REDACTED]) finds a bottle of ammonia-based cleaner in a bathroom. SCP-254-1 reprimanded for carelessness. Fellow janitor █████ ███████ observed in a verbal altercation with SCP-254-1; both parties are somewhat vague on the cause of the quarrel.
Day 43: SCP-254-1 again observed to be apparently drunk on duty. Cleaning is becoming noticeably more erratic.
Day 48: Fire alarm goes off in Sector-███. False alarm. Ink markers fail to pinpoint a culprit, but SCP-254-1 was observed near the tripped alarm a few minutes prior to the incident. Security footage unavailable due to an unidentifiable object blocking the camera's view of the hallway.
Day 56: Dr. ████ upbraids SCP-254-1 for removing perishable items from the lab refrigerator and shredding irreplaceable experiment logs. SCP-254-1 calls Dr. ████ [REDACTED] and threatens to [REDACTED]. Security called.
Day 58: Kitchen knife found stabbed deeply into Dr. ████'s whiteboard. Dr. ████'s locked secure document safe has been opened and rifled. Guard posted at the door to Dr. ████'s office. SCP-254-1 and █████ ███████ recorded arguing in raised voices in the staff break room.
Day 59: Janitor █████ ███████ signs in to work, but fails to report to supervisor. Located by accident several hours later trapped in the cold storage rooms attached to [REDACTED] autopsy theater, suffering from severe hypothermia. Guard on duty at Dr. ████'s office incapacitated by a blow to the head; crude human figure formed from a mop head impaled on a broken mop handle driven through Dr. ████'s desk chair. SCP-254-1 nowhere to be found.
Day 60: At Dr. ████'s request, and with approval from [DATA EXPUNGED], SCP-254 removed from the wall. SCP-254-1 leaves the building and vanishes.
Day 61: SCP-254-1 caught on camera in Sector-███ late at night. Power failure and multiple backup system failures cause ██ containment breaches, resulting in ██ direct casualties and ██ further losses from sterilization of an outbreak of SCP-███ (see Incident Report 254-0210g).

Item #: SCP-255
Object Class: Keter
Special Containment Procedures: Tissue samples and specimens related to SCP-255 are contained at Bio Site-16, a purpose-built containment and research facility designed to Priority Beta contagious phenomenon specifications. Bio Site-16 is subject to a remote location personnel rotation waiver in addition to standard contagious phenomenon preventive quarantine periods. Bio Site-16 is located in the Vaitupu Atoll of Tuvalu on an island owned by Ragnarik Ecological Modeling Inc., a Foundation front organization.
Persons and animals determined to be infected with SCP-255 are to be secured and transported to a designated temporary holding facility prior to transfer to Bio Site-16. In cases where capture of an SCP-255 carrier is exceedingly difficult or impossible, lethal force is authorized.
The Office of Celestial Anomalies is to continually track the orbit of 3214 Hybris, maintain a schedule of upcoming near-Earth flybys, and alert the Research Director if any changes in observed orbit occur. The next scheduled flyby of 3214 Hybris is 11 November 2023, when it is predicted to pass within 950,000 km of Earth.
Description: SCP-255 is an anomalous infectious phenomenon of extraterrestrial origin, manifesting in most living subjects as a neurological disorder with varying symptoms. Eligible carriers of SCP-255 have thus far been observed to be organisms possessing a cerebral cortex with approximately ≥5.4 billion neurons. Experimentation has determined that species capable of contracting SCP-255 include humans, chimpanzees, African elephants, bottlenose dolphins, false killer whales, and others.
In non-human carriers SCP-255 causes, through unknown means, degeneration of motor neurons and nerve cells. The rate of degeneration and severity of related symptoms is inversely related to the number of neurons the subject possesses in its cerebral cortex, with less neurologically-developed organisms displaying the most debilitating effects.
The effects of SCP-255 on humans, however, is markedly more complex. While degradation of brain cells and the nervous system has been noted on a limited basis in humans, a range of more unusual symptoms occurs in these subjects. See SCP-255 Research Log for more details.
Individuals infected by SCP-255 can be reliably diagnosed through EEG observation and confirmation of verified markers in measurements of neurological activity. See Appendix B for further documentation.

Signature SCP-255 EEG pattern, observable thirteen seconds after commencement of observation protocol

Outbreaks of SCP-255 coincide with close flybys of 3214 Hybris, a relationship that was theorized using advanced statistical models following the second outbreak in 1965, and confirmed during the asteroid's 1987 close approach. Observations of 3214 Hybris have determined it to be an approximately 110 meter C-type asteroid with no anomalous properties observed at this time. The nature of the orbit of 3214 Hybris brings it into close approaches with Earth once every 11 years.

The first known outbreak of SCP-255 occurred in 1968, known now to have coincided with 3214 Hybris passing within 350,000 km of Earth. All known infected individuals resided within 7 km of the township of Mawlaik.
Foundation assets became aware of SCP-255 while investigating an unknown illness affecting certain primates, including humans, in rural regions of northwestern Myanmar. The number of animals affected is unknown, but was estimated at the time to be between 1,000-5,000 individuals, primarily among forest-dwelling monkey species.
All human instances and a representative sample of infected monkeys were brought under Foundation control, and special containment procedures enacted. In controlled laboratory conditions, animal subjects displayed advanced signs of motor neuron impairment, with a 100% mortality rate over a period of three weeks. Human subjects displayed mild neurological impairment, comparable to that experienced after a minor stroke. Experimentation confirmed that the disorder was not contagious. All human subjects recovered within ten days, and were released without incident after being informed that they were treated under a World Health Organization initiative.

A second SCP-255 outbreak occurred in 1979 in three separate regions, undetected until 19 months later when a routine review of forthcoming medical literature documented several individuals complaining of a "phantom limb" sensation affecting the dominant hand, simulating the spastic movement and persistent ache of an extraneous eleventh digit.
Foundation personnel covertly interviewed subjects claiming to be affected by this phenomenon. Subsequent research determined that all individuals resided within 25 km of the 11th parallel south, and were experiencing an anomalous condition. Lack of person-to-person transmission capabilities were confirmed, and disinformation measures in the scientific community were carried out, achieving effective containment.
The second outbreak was classified as a separate SCP designation until 1984, when research determined it to be the same phenomenon as SCP-255.

The third documented outbreak of SCP-255 occurred in Chihuahua, Mexico, in 1990, coinciding with the passage of 3214 Hybris within 550,000 km of Earth. Characteristic of SCP-255, the outbreak is noted to have started in what was at the time the eleventh-most populous city in the eleventh-most populous country on Earth. Beginning in this instance and continuing through subsequent outbreaks, only human subjects have been infected by SCP-255.
Affected subjects in this outbreak displayed altered circadian rhythms, sleeping for periods between 3-4 hours at a time and awaking fully refreshed, conducting activities, and then tiring and sleeping within an average period of 7 hours, thus operating biologically in accordance with an eleven-hour day.
During interactions with researchers, test subjects displayed a tendency to change subjects in the middle of speaking to say "hello" in either English, Portuguese, or Indonesian, the languages spoken by infected subjects in the second outbreak. Subjects would state "hello" in one of these languages regardless of any prior linguistic knowledge, and uniformly claimed no recollection of doing so. Additionally, these subjects would address Foundation personnel as members of the World Health Organization without prompting. In all other manners, test subjects observed in this iteration of SCP-255 functioned in their altered biorhythm in a normal manner, before recovering and returning to a normal, non-anomalous state within 2-3 weeks.

The fourth outbreak of SCP-255 took place in an office building in the 12 de Octubre Avenue Business District of Quito, Ecuador. At the time of the outbreak, Ecuador had a population of approximately eleven million people. Additionally, the building in which the initial outbreak was localized was eleven stories high. The fourth outbreak is the first observed instance of SCP-255 being transmitted from person to person, with an incidence rate in laboratory conditions of 13.9%. Infectious iterations of SCP-255 have since been observed to be transmitted from person to person by sustained close proximity (generally within a 2 m radius), despite the lack of observable pathogens. This change in pathogenicity, along with the higher initial number of cases, was responsible for the reclassification of SCP-255 to Keter effective 23 December 2001.
Foundation operatives seized control of the building under the established World Health Organization cover. The size of the outbreak, however, mandated heightened secrecy protocols. Test subjects were transported to Bio Site-16 for observation.
Similar to the second outbreak, infected individuals reported experiencing a phantom limb-like sensation. However, in this event the phenomenon was intensified greatly. Test subjects reported the sensation of seven additional limbs, originating at seemingly random points of the body with no apparent relation to existing anatomy. While the precise nature of the additional appendages was difficult to ascertain, infected persons reported that they felt as though they had three joints, were approximately a meter in length, and had no structure analogous to a hand or foot at the end. These "limbs" were apparently not subject to the painful contractions and sensations normally associated with amputees. However, subjects uniformally reported heightened distress at the sensation of seven additional limbs, moving independently of their control at most times.
Additionally, test subjects lost conscious control of their left arms. At most times, subjects were unable to move their left arms. However, at 1100 hours local time each day, the left arms and hands of infected individuals would independently make motions analogous to what appeared to be the act of writing. When supplied with pen and paper, these individuals all wrote, in crudely formed script, the numbers "11 11 65", theorized at the time to be the date of the next outbreak, and confirmed eleven years later.
All infected individuals ceased to be affected by SCP-255 within 3-4 weeks. Test subjects were administered broad spectrum amnestics and released to Ecuadorian authorities. Foundation assets within the World Health Organization disseminated disinformation related to an exotic strain of malaria and subsequent treatment efforts as part of containment efforts.

The fifth and most recent outbreak of SCP-255 took place in Brussels, Belgium, where 11 individuals working on the eleventh floor of the NATO headquarters building all complained to medical staff of constantly hearing a set of eleven electronic tones, repeating constantly. Containment protocols were activated by Western Europe Sector personnel, and all infected subjects were transported to Bio Site-16.
Test subjects continued to complain of hearing the repetitive set of tones. Most subjects experienced heightened stress and irritability, as well as sleep deprivation. Infected individuals were administered sedatives to ameliorate secondary SCP-255 symptoms. Testing of this group of infected individuals revealed the incidence rate of SCP-255 was now 100%, ensuring that any humans exposed to the subjects would contract it.
Eleven days after the test subjects were secured at Bio Site-16, infected individuals reported a cessation of the perceived repetitive tones. One test subject immediately reported hearing an "electronic" voice, similar to that generated by speech simulation software, repeating the Spanish word "estrella". Once the subject reported the phenomenon to researchers, it immediately ceased, whereupon another of the original eleven test subjects reported a similar phenomenon. The original cluster of infected individuals appear to comprise a phrase in this manner, the constituent words of which were repeated in order for every new case of infection beyond this group. The phrase is transcribed below, translated from Spanish to English for this version of the document:

BINARY STAR LOST NOT LOST TRANSPOSE DEAD INSTRUCTION URGENT AWAIT TRANSMISSION

Upon relating to researchers this particular symptom, all test subjects ceased to display any signs of SCP-255 infection. Subjects were amnesticized per SCP-255 guidelines and released.
