SCP-160

Item #: SCP-160

Object Class: Euclid

Special Containment Procedures: SCP-160 is to be contained in a 20 m x 10 m glass enclosure at Site-77, with a sliding door and climate control system. A video feed of the interior of SCP-160's enclosure must be maintained at all times. SCP-160 may not be moved outside of its enclosure for any reason, and must be fed on a regular basis and provided with fresh water. Any attempts to remove SCP-160 from its enclosure must be approved by two Level 4 personnel, and all personnel entering the level containing SCP-160's enclosure are required to wear full protective clothing.

Description: SCP-160 is an undescribed breed of domesticated dog. DNA testing shows no human, canine, or feline genetic material within its cells. SCP-160's body structure is that of a normal domestic dog, but its skin and brain are composed entirely of regenerative plastic, obscuring all internal organs. When still in its enclosure, SCP-160 has shown no physical signs of aging or injury. The only exception to this was when it sustained a circular wound on its forehead approximately four months ago. Within three days, the wound had completely healed, leaving no trace of the wound or scar.

SCP-160 has one anomalous property: it can move through solid objects at will. Testing has shown this ability to extend beyond its enclosure; however, SCP-160 is not capable of passing through walls in any direction other than its enclosure wall (or the surface it occupies). While in motion, SCP-160 exhibits no physical impact whatsoever on the object it is moving through, so long as it remains in headfirst motion. SCP-160 will move through any nonoptic material at its speed until it reaches the limits of any medium it may be moving through; however, cameras cannot detect movement past the speed of light. No mechanism short of teleportation has been found to allow SCP-160 to traverse gaps larger than 20 cm wide; however, once inside an enclosure with solid walls and doors, it will use means outside of Foundation knowledge to pass between these obstacles.

If left unsupervised for more than three minutes, the anomalous properties may manifest themselves in ways related to escape or assault on personnel and/or juveniles within Site 77; this effect will intensify if exposed for longer periods on any given day. In addition, should a canine be introduced into Site 77 without having previously met SCP-160 (through either crossbreeding or breeding from normal dogs), then only that particular dog will exhibit behavior associated with escape/attack scenarios in response to its presence; however, the other dogs present will continue to exhibit normal behavior in their presence. It currently appears that the most recent incident involved two Deltas (dogs trained for explosive detection) and a young child being presented with SCP-160 during a training class; all three were found alive after approximately one hour's time, but severely injured and unconscious with severe burns over most of their bodies. Following these incidents involving juveniles, all staff members are required to carry stun weapons while working with SCP-160.

Addendum 160-1: On 03/12/2011, SCP-160 escaped its enclosure for the first time. The only known means of opening its enclosure door were through the use of a key card and electronic keypad. After thirty minutes of testing four separate random keys and opening SCP-160's enclosure with each one, the SCP-160 containment door opened from within. There was no sign of SCP-160 inside the enclosure at this point, nor had any other member of staff been in the enclosure since SCP-160's initial containment breach. A search of the interior of SCP-160's enclosure revealed no signs of entry or exit.

At approximately 13:00 hours, a large plastic dog toy with a single eye on it (designated SCP-160-1) was discovered on the floor of SCP-160's enclosure. This is believed to be the first instance of SCP-160 using its anomalous properties to escape when unsupervised. SCP-160 has not been observed using SCP-160-1 again.
