Item #: SCP-3604
Object Class: Euclid
Special Containment Procedures: SCP-3604 is to be kept in a large, locked container at all times. Container is to be cleaned on a weekly basis. No more than 2 janitors may enter at a time. Large chunk of meat must be provided to SCP-3604 via chute provided in Observatory-32 before cleaning container. Both janitors must meet their job quota before SCP-3604 has finished its meal.
Description: SCP-3604 was found inside of living quarters consuming a humanoid before capture and containment in site-██, origins unknown. It consists of a spacious size, achromatic fur, luminescent, empty eyes, red marks on its face, and forearms with hands similar to a humanoid’s hand.
SCP-3604 is an extrememly bulky and hostile creature, attacking anything in its site. It mainly targets anything made of meat. Its main attack pattern is to bight down hard on the neck of its prey, killing it quickly, it then proceeds to feast on the victim.
SCP-3604 has shown to run at speeds up to 83 mph, while showing no sign of weariness after a 5 mile run. Its nose has shown to sniff out the scent of anything within approximately 3.5 miles away, meaning it can smell the scents of subjects 2x farther than a wolf’s nose.
Personnel have reported howling from SCP-3604 that triggers a fear reflex in themselves, thus resulting in the personnel requesting thicker walls be built around SCP-3604.
