Item #: SCP-5181
Object Class: Euclid
Special Containment Procedures: Site ██ is to maintain in working condition a designated Chamber-5181 of dimensions of at least 8m x 8m x 3m. Chamber-5181 is to have at least three double doors placed on different wall sections, and is to be stocked with only one table, one chair and one overhead light fixture, which shall be replaced daily as needed. No doors or other openings of Chamber-5181 are permitted to lead directly to an outdoor area.
Senior Researcher Peters is to take his single daily meal in Chamber-5181 at between 10:00 and 12:00. He may choose from the predefined menu of high protein and high calorie compact food items on file 319-5181, the ingredients for which must be kept in stock by the site kitchen. A course must satisfy the working parameters of providing appropriate daily dietary intake while being reasonably consumable within less than 10 minutes without gastrointestinal distress. During his meal, Senior Researcher Peters must be accompanied by six assigned security personnel of exceptional physical fitness, who will assist him in leaving Chamber-5181 safely following the initiation of SCP-5181.
Senior Researcher Peters is to stay indoors at Site ██. Short intervals of less than two hours may be spent outside in the vicinity of Site ██, for work or health purposes, at the discretion of Site administration, and if accompanied by two security personnel. Any longer duration or longer distance travel off-site requires Level 4 review and approval.
As per executive decision EC-5181-[REDACTED], Senior Researcher Peters is to continue his current work assignments at the Foundation, and may not be classified as an SCP object, in this file or elsewhere.
Description: SCP-5181 is a phenomenon affecting Senior Researcher Peters. Approximately ten (10) minutes after consuming any food item (which also includes any liquids with nutritional content), the chamber1 currently inhabited by Senior Researcher Peters will experience a low interference extradimensional event. The first phase of the event consists of the spontaneous manifestation of a varying amount of enlarged carrots (classified as SCP-5181-A) inside the chamber. SCP-5181-A instances have been recorded with lengths of between 1.5 and 3.2 m and masses of 40 - 110 kg. The presence of SCP-5181-A invariably results in significant obstruction making traversal of the affected chamber difficult.
Immediately following SCP-5181-A manifestation, a dimensional gateway will form on a wall section extending to approximately a quarter of the affected chamber walls. The process is described as an apparent folding of the wall sections away toward the other side of the gateway, accompanied by the sound of tearing paper or cardboard. Any doors, windows, or other apertures on the affected wall section become untraversable from the outside, but similar apertures on unaffected wall sections remain traversable. Through the affected wall section gateway, an entity (classified as SCP-5181-B) becomes visible in front of an indistinct background space. SCP-5181-B is a large leporine entity with humanoid features, most notably a bipedal stance, and humanlike eyes set forward on the face. The entity will proceed to extend a pawed forelimb through the gateway, grabbing SCP-5181-A and pulling it back through the gateway. The limb has been observed to elongate and bend at multiple points along its length while reaching for SCP-5181-A, as if possessing no skeletal structure. SCP-5181-B will continue this process until all SCP-5181-A has been removed from the affected chamber. Instances of SCP-5181-A that are removed from the chamber through other entry points, and outside SCP-5181-B’s line of sight, will be ignored by it. The event is concluded by the reappearance of the missing wall section over the gateway, accompanied by the sound of a zipper closing.
Although SCP-5181-B makes no attempt to grab other objects or personnel in the chamber, the movement of its forelimb, and the size of SCP-5181-A, pose a hazard to Senior Researcher Peters and other personnel present. No objects or personnel accidentally falling through the dimensional gateway have been recovered to present and are presumed lost. The effect of SCP-5181 while outdoors is not known, and experimentation is currently forbidden as per executive decision EC-5181-[REDACTED].
SCP-5181-A instances removed from events do not demanifest, and have additional anomalous properties. If a number of at least three instances are arranged into a convex polygon shape, they will also form a traversable dimensional gateway. On the other side of this gateway is a massive cavern with appearance reminiscent of a gastrointestinal tract, and a river of thick orange liquid (presumed to be mashed carrot pulp) filling the bottom. Further exploration of this space is prevented by the appearance of a pawed forelimb, similar to that of SCP-5181-B, from one of the holes at the top of the cavern system. It can be observed through the gateway as this limb extends from a hole, drops several SCP-5181-A instances into the orange liquid, and then appears to “notice” the existence of the gateway. It will then reach for the gateway, knocking its structure over. The SCP-5181-A making up the gateway are pulled inside, collapsing the gateway. During this process, any objects or personnel on the other side of the gateway are also presumed lost.
Otherwise, SCP-5181-A has been tested to be safe for human consumption with no anomalous side effects; however, by now all personnel of Site ██ have expressed extreme distaste of carrot-based foods.
