SCP-5667
Special Containment Procedures: Any and all in SCP-5667 instances are to be contained and relocated to site-███, within an approximately forty by forty yard enclosure which is to be sealed within an airtight, waterproof re-enforced tempered glass dome. No more than 100 instances of SCP-5567-1 should be allowed in any containment chamber. More containment chambers are to be constructed as needed. The containment chamber should be inspected daily for any cracks or naturally forming damage that may allow any SCP-5667-1 instances to escape. Any and all personnel entering SCP-5667's containment chamber are to wear standard cleanroom equipment, and generously apply themselves with the most insecticide readily available that will not cause damage to the contents of the containment chamber.
Containment chambers housing SCP-5667-1 Instances are to be regularly stocked with any kind of mammal, although a preference has been shown to native species of Augusta, Maine on biweekly intervals. Note; Total game stocked within SCP-5667's containment chamber should not exceed 117.2 Kilograms at any given time. If at any point a corpse containing SCP-5667 egg instances are found, they are to be incinerated immediately via highly reactive propellants such as hydrazine. In emergency situations, M2 flamethrowers are approved for use to meet protocol deadline. Any and all deaths caused by SCP-5667's effects are to be reported to MTF Lambda-4 ("Birdwatchers") and Dr. Alcman, and cover stories published referencing the cause of death relating to the most active predator within the area. In the event of a containment breach, the most potent available insecticide is to be used in generous amounts against areas thought to contain SCP-5667. All terminated instances of SCP-5667 are safe to handle and can be disposed of via incineration via the same as earlier specified in the document.
Description: SCP-5667 is the designation of an arachnid group that appear physically indistinguishable from the American Deer Tick (Ixodes scapularis). Individual instances of this group are designated SCP-5667-1. The life cycle, behavior, and habitat range of SCP-5667-1 Instances are consistent with their physically identical counterpart, however their reproductive method and diet are drastically different. When any living organism comes into contact with any SCP-5667 instance, it will undergo differing changes which depend on the organism it designates as prey.
SCP-5667-1 instances seem to prioritize efficiency when dealing with eliminating their given target, demonstrating low-level reasoning in order to select a practical method of termination. SCP-5667-1 instances will often target specific weaknesses belonging to the chosen host (See incident log: SCP-5667-2)
Once firmly attaching itself to a host (designated as SCP-5667-2) in a similar fashion to its non-anomalous counterpart, it will begin to rapidly mutate its internal and external organ structure over the course of several seconds to several minutes as to most effectively kill the organism. Once SCP-5667-2 has been terminated by SCP-5667-1, the SCP 5667-1 instance will imbed itself into the carcass of SCP-5667-2 and begin to burrow within its flesh. The SCP-5667-1 instance will then seek out a suitable breeding ground, usually found within the lungs, liver, or large intestine.
Once a favorable environment has been acquired, the SCP-5667-1 instance will exit via the same point of entry and seek out an SCP-5667-1 instance of the opposite sex and lead it back to SCP-5667-2 to mate and lay approximately 4-6 dozen eggs within the selected breeding location. However, this number will rise into the hundreds if SCP-5667-2's biomass is over 118.2 Kilograms. The incubation period for eggs laid is consistent with that of the Ixodes scapularis. Following laying eggs, both parent SCP-5667-1 instances will enter a state of fatigue, and over the course of three hours will expire from natural causes.
| INCIDENT LOG #1 | |
| Subject | Humanoid Female (Homo Sapien) |
| Incident | On June 17th, 20██ one ████ Richardson left her home to go on a hike on a locally known and well traveled trail in Kennebec, Maine when at some point, an SCP-5667-1 instance attached itself to her body. |
| Results | Upon attaching itself to Richardson, SCP-5667-1 rapidly manifested bacterial colonies of Vibrio Cholerae in its mouth, after which it began to feed the colonies into the salivary glands and delivered the bacteria into the bloodstream continuously. Richardson collapsed onto the ground roughly fifteen minuets after the initial attachment of SCP-5667-1. Cause of death was determined to be a severe case of Cholera. Notably, Richardson (now referred to as SCP-5667-2) had both Type O, and extremely low stomach acid contents - Factors which are known to put one at increase risk of Cholera, which may have been the reason for SCP5-5667-1's termination approach. Upon discovery of SCP-5667-1 eggs within SCP-5667-2, the Foundation was notified and locally stationed agents recovered the SCP-5667-2 and transferred the instance to site-██ incineration as per standard containment procedure. |
| INCIDENT LOG #2 | |
| Subject | Humanoid Male (Homo Sapien), German Shepard (Canis lupus familiaris) |
| Incident | On November 20th, 20██ ██████████ Pavlov was out hunting with their dog. At approximately 20:47, two SCP-5667-1 instances attached themselves to both ██████████ and the dog - found with the name 'Sam' on the collar. |
| Result |
Within moments of attachment, the SCP-5667-1 instances on ██████████ (Designated SCP-5667-2A) mutated, and an manifested an ovulary that slowly developed seeds of the arachis hypogaea within it which were then processed into oil through unknown biomechanical means and fed into ██████████'s bloodstream via the salivary gland. Within minuets, ██████████ suffered an acute anaphylactic reaction, expiring within ten minuets due to asphyxiation. The SCP-5667-1 instance attached to the German Shepard (Designated SCP-5667-2B)'s mutation began with an series of changes to the chelicerae. After a period of two minutes, had manifested microscopic follicle structures similar to those found on the Chironex fleckeri at which point it imbedded its chelicerae into skin, causing intense pain and sending SCP-5667-2B into shock, after which it expired. Both SCP-5667-2A and SCP-5667-2B were found approximately three days later partially decomposed, with a total of over 120 instances of SCP-5667-1 eggs in internal organs. Both bodies were incinerated as per standard containment procedures. |
Addendum: Incidents with SCP-5667-1 are somewhat frequent due to the size of the currently known SCP-5667-1 habitat range. Full containment of all instances is undergoing. Its origin is currently unknown, as are the methods through which SCP-5667-1 is able to mutate. However an unusual aspect of SCP-5667-1 instances are that they appear to be drawn to areas emanating a cappella singing style. The reason behind this is unknown, though in all cases it appears to be a natural 'migration' instinct. Any and all information relating to SCP-5667 is to be forwarded to Dr. Alcman for study.
