SCP-5113

A guard must always be present and watching SCP-5113 in the event that it manages to traverse through its containment, as motion and heat tracking mechanisms have all failed to detect it.

Background:  SCP-5113 appears to have been formed from the tar pits of Pitch Lake in Trinidad, having formed and congealed from the pressure of an ancient SCP's remains some hundreds of thousands of years ago. Its copying and morphing properties lead researchers to suspect it is related to SCP-1411, which is documented in the attached file, Abstract-5113-A. It is suspected it emerged from the tar pits perhaps tens of thousands of years ago (or more), as it claims it witnessed the original settlement of Trinidad by Amerindians some 7000 years ago after a long period of the island going uninhabited. [SCP-5113 describes a 'short' period as some thousands of years].

It is believed it since roamed the island and adapted to various tropical plants, animals, substances, and original Trinidadian people until it gained the ability to shift, chameleon, and utilize speech for rudimentary communication. Sometime during the colonization period, it is thought to have boarded a ship that was en route to the United States, where it has since traversed the eastern coastline of the United States in search of moist climate once again.

As of the 20th century, it had settled in the city of Burlington, Vermont, seemingly content with the humid and swampy nature Lake Champlain and heating from the nearby train yard for the time being. It seemed to have wanted to master human transformation so as to ask for directions and transportation back to Trinidad.

Capture: SCP-5113's existence was discovered on 8/12/1998, when conductors from the Vermont Railway Company in Burlington, Vermont noticed inexplicable rust, rotting wood, and and slimy substances coating their rail cars and surroundings. Such sludge had been reported for years with no apparent cause, and went without investigation until a railroad worker stumbled upon a large moving lump of sludge caught between the tracks and wheel.

Agent [REDACTED] investigated the occurrence, happening upon SCP-5113 by chance after a few hours. SCP-5113 was then lured into Foundation containment with sweet-talking and promises of return to its humid island of origin.

Testing: Testing on or with SCP-5113 is strongly ill-advised due to its ability to easily escape during experiments. Testing on SCP-5113 must be approved by a Level Three clearance and appropriate precautions to prevent its escape must be ensured and tried before experimentation.

ADDENDUM: After experiment 06-KW, Level 6 testing regarding SCP-5113 is strictly prohibited, especially Class K experimentation. Utilizing SCP-5113 in experimentation with inanimate SCPs must be approved of by a Level Four clearance, and experimentation with organic SCPs must be cleared by three Level Four members.

03-OB-1: SCP-5113 has been discovered to have the remarkable ability to secrete itself through solid material. Testing with materials of various lengths, thickness, density, and opaqueness has been attempted. It appears able to pass through any solid substance at will, no matter the quality. SCP-5113 has been complying through the testing process, believing it to be a game of sorts. Experimentation failed, leaving no containment suitable for SCP-5113 for the time being. Thankfully, it is rather dull and doesn't appear to suspect that this is a ruse yet.

03-OB-2: Continued 03-OB experimentation, this time with various liquids. SCP-5113's density appears to fluctuate depending on what sort of liquid it is present in, absorbing part of the liquid to remain sufficiently 'goopy' in the containment. It seemed particularly pleased with water and oil, considering this as a reward for sufficiently passing the previous round. It is immune to damage and harm from toxic liquids and poisons, however, it seems to retain some of the liquid's properties, as contact with the SCP after exposure to dangerous substances resulted in exposure as though there was direct contact with a diluted version of the toxic substance.
