Scp-2067 "The Whisperer"
An invisible to the naked eye being that can only be seen under ultraviolet light some have described Scp-2067 being a black spherical object that leaves a trail of a glue-like substance behind it. But since most of the people that see this people go insane upon first sight it is hard to know what is true. The black glue-like substance cannot be identified but is closely related to urine in chemical substance. This black goo had the ability to manipulate the emotions of humans because of the scentless fumes that it gives off.
