**Item #:** SCP-3145 **Object Class:** Euclid **Special Containment Procedures:** SCP-3145 is to be kept in a locked container at all times. The enclosure must be cleaned biweekly. Personnel are to enter SCP-3145's container in groups of no less than 3, with the door locked behind them. Two personnel must maintain continual direct eye contact with SCP-3145 until all personnel have vacated and relocked the container. Personnel are to alert one another before blinking. Any change in sounds originating from SCP-3145's containment chamber should be reported to the HCML supervisor on duty. **Description:** SCP-3145 is a sculpture constructed from concrete and rebar, with traces of Krylon brand spray paint. Its origin is unknown. SCP-3145 is animate, but cannot move while in direct line of sight of a human being. When a human breaks eye contact with SCP-3145, it will move at high speed and attack the individual, typically by snapping the neck at the base of the skull. Strangulation has also been employed. When SCP-3145 is not under observation, personnel have reported sounds of scraping stone within its chamber. A reddish substance, a combination of human feces and blood, has also been observed on the floor of SCP-3145's chamber. Though SCP-3145 is believed to be the origin of this material, the actual source of SCP-3145's means of producing it are currently unknown. **Addendum: Interview 3145-01** > **Interviewed:** SCP-3145 > > **Interviewer:** Dr. Falzon > > **Foreword:** A change in the sounds coming from SCP-3145's chamber was reported on 04/09/94 to Dr. Falzon, HCML supervisor on duty. Investigation led to SCP-3145 requesting an interview. A screened porthole was installed in the chamber door to facilitate communication. > > **<Begin Log, 09:50>** > > **Falzon:** How are you finding your accommodations, SCP-3145? > > **SCP-3145:** Not bad, not bad. You know, I really appreciate you guys cleaning up after me. Honestly, I don't even know where that stuff comes from. > > **Falzon:** It's the least we can do. Is there anything I can get you? > > **SCP-3145:** Well, uh. //[laughs]// Maybe train your D-Class a little better? I mean, not //too// good, I don't want to kill them //all//. But they've been screwing up pretty bad lately, and I like a little challenge. > > **Falzon:** I see. I suppose I shouldn't have expected anything else. > > **SCP-3145:** Hey, don't judge. Being an unstoppable, well, //mostly// unstoppable, killing machine is fun! > > **Falzon:** Fair enough. Is there anything else I can do for you? > > **SCP-3145:** No, I think I'm good. Thanks for the screen, though. Nice to get some fresh air in here for once. //[laughs]// > > **<End Log, 10:01>** > > **Closing Statement:** Request to leave porthole open when SCP-3145 not under observation denied. Investigation of the origins of both the materials found in SCP-3145's chamber and its ability to vocalize are ongoing.
