Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Objects containing an instance of SCP-XXXX are to be contained in a room at a distance of at least four meters from the room's walls, floor and ceiling. Multiple SCP-XXXX instances may be contained in the same room. Supports used to suspend SCP-XXXX instances above the floor are not to contain any hollow spaces.

Description: SCP-XXXX is an amorphous mass which grows at approximately 50 centimeters per day in all directions. SCP-XXXX instances are only capable of growing in a space which has two boundaries between three to twenty centimeters apart from each other, such as the inside of a wall. An SCP-XXXX instance will grow until it has filled all available space which meets this requirement. If the space an SCP-XXXX instance is occupying is modified in such a way that it no longer meets the space requirement, the SCP-XXXX instance will begin to shrink until none of its mass is outside an area meeting the requirements. If the entirety of an SCP-XXXX instance is removed from a suitable space, it will shrink until it vanishes completely. Reconstructing a suitable container in the location an SCP-XXXX instance vanished does not cause it to regrow.

Upon filling all available space, SCP-XXXX will occasionally knock against the walls of its container. This sometimes results in noises being audible outside of the object SCP-XXXX is inhabiting. Each knock indicates an attempt by SCP-XXXX to create a new instance of itself. For each attempt, an SCP-XXXX instance will spawn in a random location within 3.5 meters of the location SCP-XXXX knocked. The new instance starts as a sphere approximately 1.1 millimeters in diameter, and will either vanish, or grow into a new SCP-XXXX instance, depending on whether it spawned in a location suitable for growth. The size of an SCP-XXXX instance does not appear to affect the rate at which it attempts to spawn new instances.

Addendum 1: SCP-XXXX was discovered in the town of Modesto, California, when Foundation agents were alerted to a potentially anomalous mass removed from a patient's stomach at a local hospital, later determined to be an instance of SCP-XXXX which had spawned inside the patient’s body. Examination of the patient's household revealed a total of seventeen instances of SCP-XXXX within various segments of the walls and floor. These sections of the building were removed and brought to Site-23 for storage.

Addendum 2: Interview with patient

Interviewed: Manuel Soto

Interviewer: Dr. Garrett

Foreword: This interview was conducted after the discovery of SCP-XXXX within Soto's household.


Dr. Garrett: Thank you for your attendance, Mr. Soto. I trust that you're feeling better now?

Manuel Soto: Uh, yeah. Are you one of the doctors? I didn't know they interviewed patients.

Dr. Garrett: The parasite you were infected with isn't… normally found in the U.S. We are researching where it might have originated.

Manuel Soto: Uh, I've never been outside the country before.

Dr. Garrett: Can you tell me if you've noticed anything abnormal in your home recently?

Manuel Soto: Well there's… uh… I mean, I don't think it's related to my illness.

Dr. Garrett: Any information is useful to us. What is it you were about to say?

Manuel Soto: Alright… promise you won't think I'm crazy or anything, though. So, for the past month at least, I've been hearing these… thumping sounds, coming from the walls in my house. At first, it was just this one wall in my room. It might've been there longer than that, I don't know. I didn't think much of it, because, everyone hears those noises sometimes, right? When you're all alone, in a quiet room? Anyway, over the month it's gotten… more frequent.


Dr. Garrett: Go on.

Manuel Soto: At first it was just one, every few days, but they started getting more and more frequent, sometimes a few thumps in a row. Thump, thump, thump. So I called a guy, maybe three or four days ago, to see if I could get it checked out. Said he'd be able to come in a couple of days. I figure, I can wait a couple days, it's just an odd noise. That night, though… I could barely sleep. Thump, thump, thump, all night long. A whole lot louder, too. Knocked some things off my shelves even. Must've been two in the morning before I finally managed to fall asleep.


Manuel Soto: Anyway, next morning, I wake up with this killer stomachache. I tried taking some antacids, but they didn't seem to do anything. Not to mention the walls were still thumping away at me. So I decided to come to the hospital here.

Dr. Garrett: Anything else?

Manuel Soto: I know it sounds crazy, but… I swear, it seemed like whatever's been making that noise, it knew I was about to find it.


Closing Statement: Manuel Soto and involved hospital workers were amnesticised, and the damage to Soto's household was explained as the result of a termite infestation.
