The Snake

Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: SCP-XXXX is to be kept in a simple storage container at Site-██ guarded by 2 guards at all times. No unauthorized viewing will ever be allowed, and any attempt at doing so will result in immediate termination.
Description: SCP-XXXX is a simple ████ branded USB flash drive found by a cell guard at Site-██.
Located on the USB Flash Drive is a single image, SCP-XXXX-1, 73 MB in size. When SCP-XXXX-1 is seen, the viewer will immediately start having intense shaking of the lower body up to the top, until they enter into a seizure like state of shaking and foaming from the mouth. 3 minutes after this event has happened, the original viewer will start shedding their skin into a shell, to reveal their inner body. They will then stiffen, and a worm like creature will erupt from their stomach, SCP-XXXX-2. SCP-XXXX-2 will then look for any other humanoids in the area it was created in, and then entangle them, causing immediate death, and taking over of the freshly killed body. SCP-XXXX-2 has been observed to be a snake-like parasite, made up of muscle tissue, and bone. It is directly connected to the heart of the viewer, using it to live. But 24 hours after the original event of SCP-XXXX-2 forming, it will die, and also kill the host, unless if it has taken over a new host. Then, the 24 hours would restart. If SCP-XXXX-2 is killed off before this 24 hour period, the host will still live, but in a state of coma. This state is irreversible. SCP-XXXX-2 has been able to be preserved past 24 hours with the use of artificial means. It seems to be sentient, having a similar intelligence of a simple house pet.
