SCP-511 is a mass of biological matter taking the form of a large 
feline, often with extra limbs, eyes, mouths or other organs. It is 
typically coated with dirt, blood and fecal matter, making its fur 
appear black despite its actual coloring. (Tests have shown 
SCP-511’s fur to actually be a random patchwork of various feline 
coat patterns, colors, and lengths.) SCP-511’s mass varies from 
10kg to over 50kg, roughly in proportion to the number of 
SCP-511-1 in the associated colony. The tissue that makes up this 
mass consists primarily of the bodies of deceased SCP-511-1. The 
portion of SCP-511 that does not comprise SCP-511-1 consists of 
other biomass; small rodents, various plant materials, insects and 
insect larvae, black mold, a human [DATA EXPUNGED]. 
Incorporation of dead tissue into SCP-511 does not appear to slow 
the normal process of decay. Different areas of SCP-511 undergo 
different stages of biodegradation at any given time; some areas 
show little more than lividity, while other areas may show active 
carrion insect infestation, and some areas may even show 
liquefaction of tissues. (Note: Researchers have described SCP-511 
making a “purring” sound. Tests have shown this sound does not 
originate with SCP-511, but is actually the sound of insects, most 
often blowflies, trapped within its mass— Dr. A. _ ) 


SCP-511 prefers to inhabit dark spaces with a relatively high 
humidity, such as old basements and crawl spaces. It will continually 
scavenge its immediate area for new biomass to incorporate into 


subjects. An organized queue appears to form 
after the first round of questioning makes its 
way around all the test subjects. D-Class 
subjects at no point deviate from this order 
after it is established. Efforts to deviate this 
order is met with failure. 


After approximately 55 minutes the test was 
terminated and all D-Class systematically 
removed via tethers. During debriefing, it was 
noted that all test subjects displayed 
previously observed post-test symptoms but to 
a lesser degree. Subject described being 
aware of what they were doing, but stated they 
could not stop themselves, and just "wanted to 
remember". 


Researcher Notes: Due to differences in 
height, weight and build in available test 
subjects. We have concluded that the upper 
limit to the effect projected by SCP-3944 is 
only limited by the number of subjects that can 
fit within a 1m radius from the edge or surface 
of the object. It is also our recommendation 
that any researchers wishing to test 
SCP-3944, and not expose subjects to high 
mental stresses, should limit exposer to under 
60 minutes. - Dr. Daniels 


*Site Director: Further research into the limits of 
SCP-3944 and side effects of prolonged exposure 
approved. * 


+ Test Log-03: Stress Test 


Test #: 3944-03 

Test Subjects: 4 D-Class subjects. 

Test Parameters: Ascertain If SCP-3944 has 
a limited effect duration as well as any 
lethality. Subjects will be instructed to sit 
around SCP-3944 on 4 non-anomalous chairs. 


Once subjects are successfully under the 
influence of of SCP-3944, researchers will 
monitor D-Class fora total of 1 week. After 1 
week, test will be terminated and D-Class 
extracted if possible. 


Results: Researcher Daniels instructs 
subjects to take their seats at SCP-3944. After 
a short duration subjects, begin conversing 
followed by the onset of SCP-3944's main 
effect. The effect persists, unending for 1 
week. During this time, the D-Class 
experianced no sleep deprivation, signs of 
hunger or dehydration, as well as no signs of 
vocal damage that would be expected after 
such extraneous vocalizing. 


This ability to stave off bodily degradation only 
lasted while all subjects were under the 
influence of SCP-3944. Once the number of D- 
Class within the area of effect was reduced 
below 4, all subjects either lost consciousness 
or experienced seizures. Subjects struggled 
greatly to speak with researchers. After 
receiving medical treatment, those subjects 
that regained the ability too speak were no 
longer capable of forming coherent sentences. 
D-04 expired immediately during cessation of 
test. 


Researcher Notes: SCP-3944's ability to 
essentially keep its victims alive while 
subjecting them to extreme mental abuse is 
profound. Based on D-Class testimony, the 
effects of SCP-3944 on their psyche is 
extreme following prolonged exposure. 


It is the opinion of both Dr. Shanon and myself 
that further testing not be carried out. We feel 
we have sufficient data to secure and contain 


SCP-3944. - Dr. Daniels 


*Site Director: Testing will continue until we understand 
the full capability of SCP objects in our care. Another test 
is scheduled and approved to ascertain the full scope of 
SCP-3944's effects. Researcher Daniels and Junior 
Researcher Shanon have been denied transfer and will 
perform the test as scheduled. *

Test Subjects: 4 D-Class subjects henceforth 
designated D-01 though D-04. Subjects have 
been sourced as such, that they both maintain 
baseline mental faculties and are no longer 
able to participate in other activities due to 
severe injury. 

Test Parameters: This test will ascertain 
effects of extreme exposure. All subjects will 
be instructed to enter the area of effect of 
SCP-3944. D-Class subjects will be fitted with 
tether harnesses for extraction. 


Subjects will be monitored via an automated 
surveillance system. This system will be 
programmed to alert researchers to any 
change in previously observed behavior. This 
will allow for extended monitoring of the test 


without physical observation. 


Test will conclude once behavioral deviation 
occurs or a total of years pass.

to changes in SCP-3944-1 behavior. D-01 can 
be seen leaning over SCP-3944 and 
whispering something to the other subjects. * 


Dr. Daniels: Hello? Please respond. This is 
Dr. Daniels. 


*SCP-3944-1 subjects do not respond and are 
seen calmly sitting silently around SCP-3944.* 


Dr. Daniels: Security, please enter the test 
chamber and prepare for extraction of D- 
Class. | will be joining you. 


*Researcher Daniels and a security detail 
enter the test chamber and cautiously 
approach SCP-3944. It is at the point all 4 
instances turn to look at Researcher Daniels. * 


Dr. Daniels: D-Class, | am ordering you to 
report. Are you okay? 


All instances of SCP-3944-1 vocalize in unison 


D-01: We remember. 


D-02: We remember. 
D-03: We remember. 
D-04: We remember. 


Dr. Daniels: What do you mean "you

security to stand down.* 


Dr. Daniels: That's a bold claim. Would you 
mind telling me something | might have 
forgotten? If what you say is true then it should 
be easy. 


D-01: You mean you don't remember? 
D-02: You mean you don't remember?

D-03: No. Do you? 


D-04: | almost had it, but unfortunately, | can't. 
What about you doctor? 


Dr. Daniels: Nope, no idea. What about you? 


“After seeing Researcher Daniels under the 
influence of SCP-3944, a security officer 
activated the containment breach alarm. They 
immediately activated the tethers to extract the 
D-class from SCP-3944. Upon cessation of 
SCP-3944's anomalous effect. All instances of 
SCP-3944-1 expired, rapidly deteriorating to 
resemble bodies that have decomposed for 
approximately years.* 


*Researcher Daniels was debriefed, 
administered Class-A amnestics and 
transferred off project as per Site Director's 
request. * 


Addendum-01: 

Investigations into as well as the manufacturer that supposedly 
produced SCP-3944 were deemed inconclusive. Both parties have 
denied creating and selling SCP-3944. Both companies have been 
designated GOI-03453-1 & GOI-03453-2 and are to be continually 
monitored for further instances of anomalous goods. Testing of 
SCP-3944 is currently under the direct supervision of Site-56's Site 
Director. No further testing is currently scheduled or approved. 


Footnotes 

1. Four being the minimum number needed for activation. The upper 
limit for this effect depends on the number of subjects that can fit 
within SCP-3944's radius of effect 

2. Specific designations will be assigned based on current number 
of affected individuals. 

3. It is uncertain how SCP-3944 chooses which subjects it affects 
first. This mechanism appears random. 


SCP-3945: Big Huge Nightmare Panther 


Item #: SCP-3945 
Object Class: Safe 


Special Containment Procedures: SCP-3945 is to be kept in a 
Standard Containment Locker. The object should be covered 
entirely by a thick cloth at all times. 


SCP-3945 should never be viewed with the naked eye; all 
interactions must take place remotely. 


As per Chief Researcher Hintz, testing on SCP-3945 is suspended 
indefinitely. 


Description: SCP-3945 is the remaining biological tissue of an 
anomalous animal of unknown origin and species, currently 
contained on a Ford 150 truck tire. The tire itself displays no 
anomalous properties or unique material composition. All animal 
blood on the tire appears fresh and still maintains a vibrant red color. 
A golden bell attached to shreds of a collar is crushed between the 
tire's treads. The bell's side is engraved, determined to read 
"SHADE". Remote attempts to remove biological matter from the tire 
have failed. 


SCP-3945 was discovered after the Mayor of Lockford, CA was 
found dead in his family home of an apparent suicide. One call was 
made before his death to his wife, wherein he described seeing and 
hearing his childhood dog, Bass, in hysterics. A log of the call is 
included below. 


Call Log 
Time: 9:41 PM 


Janelle, it's Bass. My fucking dog when | was 8. Bass is 
here and then she's not, she's dying or dead, and | don't 


know...I've seen her rib cage, her heart and stomach 
opened over and over. She's got too many legs anda 
tumor on her face that | don't...remember, what's 
happening to me, | can't even think anymore, | can't go 
outside or inside or sideways without seeing THAT 
FUCKing DOG... 

(Unintelligible. Loud banging noise. Yelled profanity in 
the background. Call ends after 1 minute, 32 seconds of 
static and background shuffling noises.) 


Shortly before the Mayor's death, Lockford experienced a massive 
rise in its suicide rate. Foundation agents were dispatched after an 
article describing mass hallucination of family pets was run in the 
local newspaper. The anomaly was subsequently discovered when 
Agent Brinks began hallucinating his former pet iguana while 
inspecting the Mayor's truck. Agents removed the tire after the rest 
of the truck was determined to be non-anomalous. Despite 
administering amnestics, Agent Brinks still hallucinates. He is under 
careful supervision and Foundation psychological evaluation. 


SCP-3945 induces hallucinations via direct sight in viewers who do 
not have a living pet. If the viewer has never owned a pet, this will 
manifest SCP-3945-2. Otherwise, SCP-3945-1 will manifest. 


SCP-3945-1 are hallucinations of the viewer's pets, usually of the 
animal purported to be the "best" or "most beloved". 


Viewers describe their hallucinated pets as "different" than they 
remember, reporting elongated or shortened limbs, matted hair, dark 
pits instead of eyes, etc. In some cases, viewers reported that the 
SCP-3945-1 manifestation doesn't appear to be their pet at all, 
instead appearing as a dark shadow only similar in size and breed. 
Hallucinations occur in 5 - 60 minutes in 97% of cases. 


In each hallucination, SCP-3945-1 appears for a few minutes before 
it is killed. SCP-3945-1's death is inconsistent with the original pet's 
cause of death. Notably, 95% of tests have resulted in SCP-3945-1 
being disemboweled or devoured by an unknown predator. After the 
anomaly is killed, the hallucinated remains will disappear upon 
breaking sight line. This hallucination pattern will repeat endlessly. 


Upon repeated hallucinations, subjects begin to exhibit extreme 
emotional distress leading to depression, mental instability, and 
suicidal ideation. suicides have been recorded as a result of the 
phenomenon. 


SCP-3945-2 manifests when the subject has never owned a pet. 
This instance always takes the same shape and form as described 
by subjects: a large panther shrouded in black smoke.

D-6512: Alright. 


(D-6512 walks into the test chamber. She 
touches the tire, looking at all sides. She 
makes direct eye contact with the remains of 
SCP-3945 and wrinkles her nose.) 


D-6512: This shit's pretty gross, doctor. 
Roadkill looks kinda fresh... 


(Five minutes pass. D-6512 begins to 
hallucinate.) 


D-6512: What the fuck. Skippy? 


Dr. Booker: Can you describe what you're 
seeing? 


D-6512: This probably sounds wild, but | can 
see my old dog Skippy in here. But he's been 
dead for like, 8 years or something. C'mere,
