Do you guys know what is the scp that appears in the room that the scp-173 kill the two researchers? (in the original game, the room that you find the clipboard and you take the gas mask, the battery and some other stuff in the higher level). He looks like a leech, with a big and scary mouth and it plays a strange song when you are looking at him. You are safe 'cause the door of the lower level is blocking him, but it gives me chills anyway. If it's a real scp, what's its identification number?
And, by the way, nice job of the developers, he's scary as [REDACTED].
