ShiruKingu

Item: SCP-XXX

Object Class: Euclid, but under certain circumstances can become Keter.

Special Containment Procedures: SCP-XXX is relatively easy to contain, the problem is putting it in containment since it hides extremely well. SCP-XXX does not need to eat, sleep, drink, or partake in physical exercise. In containment, SCP-XXX stays dormant, barely moving, and will react violently if anything enters that is made of flesh. The most effective way of containing it is putting it in a steel room around 20ftm20ftm20m with heaters in the walls. If SCP-XXX starts trying to escape, personal should respond by super-heating the walls, SCP-XXX's strength is weakened in extreme heat. After SCP-XXX is overheated, personal should use heat-resistant suits, and tie it up with metal cords. They then have to wait until it calms itself.

Description: SCP-XXX has a white, cylindrical body, and stands around 15m tall. Despite it's large size, it can blend in to almost any surrounding, like a chameleon. It has Two, tall thin, crab like legs, And on either side of its body powerful spear-like arms. Atop its head are two horns and a floating orb between them. We are currently unaware about what the orb does, but we have sneaking suspicions that it grants the SCP's camouflage abilities.
It can break out of it's containment, once free it roams city streets, completely invisible. It eats small creatures, such as rabbits, for fun and once almost ate SCP-527. It does not consume the body of its victim, instead the corpse rots into nothingness. If left alone too long, SCP-XXX will grow to extreme sizes, and become a threat to humans in the area.

Addendum: Another case of SCP-XXX has been found underwater, indicating that they don't need to breath. There also have been cases of SCP-XXX found in fossil beds, though they were dead.
