Cameras should be placed in every corner of the room accompanied by heat and movement sensors, which will only be active if there is no one except for SCP-XXXX in the room. Any malfunction of the main soundproof walls should be reported immediately, Class C personnel will replace the main walls with alternative ones until the maintenance job is complete.

Description:
SCP-XXXX is a wierdly-shaped skull that shows numerous anomalies, including an eye 3 inches over the normal position and holes in it, it was found in ███████, ██████and dates back to the year ███ ██. It is possible that it was the cause of the extinction of [DATA EXPUNGED] However, this is only a theory and not enough research was done in this topic to prove or disprove it. If SCP-XXXX hears any type of sound, from a single breath to a whisper. It will instantly teleport inside the object or humanoid who produced the sound, this object should now be referred to as SCP-XXXX-A. SCP-XXXX-A will suffer from severe seizures and hallucinations for exactly 5:02 minutes, then proceed to fall in comma for 3:04:13 seconds, then die. However, this can be cured when using SCP-500. A subject who survived describes the experience here:
Interviewed: Dr. ██████
Interviewer: Dr. █████
<Begin Log, 6:00PM ██/██/████>
Subject: Where the fuck are we
Interviewer: Please be calm, you have just been cured
Subject: How am I supposed to be calm when a fucking… uh… wait a second… what was it?
Interviewer: You have just been attacked by an SCP during a containment mission
Subject: Uh, what SCP?
Interviewer: SCP-XXXX
Subject: Uh, no, I dont remember such encounter. Which one was SCP-XXXX?
Interviewer: Please tell me what you remember from yesterday at 8:00PM
Subject: I was instructed to go into SCP-173's container
Interviewer: Thanks, you may now leave this room.
Subject: Wait, what SCP where we talking about?
Interviewer: Fucking leave or we will proceed to use lethal force
<End Log, 8:00PM ██/██/████>
Closing Statement: The next day, the Subject stormed into the building shouting "I REMEMBER" and attempting to enter SCP-XXXX's Container, he used lethal force and killed his way into the container, only to be killed by SCP-XXXX
Once SCP-XXXX-A is dead, SCP-XXXX will return to the position it was in before attacking and continue with its normal behavior, regarding SCP-XXXX-A, no corpse recollection is needed. It will decompose few hours after the incident, becoming CO² (Carbon Dioxide)
