Description:
SCP-8686 is a creature discovered from SCP-8686. At first it appears to be a dark puddle but closer inspection its actually an acidic creature consuming everything it touches. But for some unknown reason our world dirt takes the longest time to absorb.
It's also known to speak. A few reports coming from staff saying that it request for raw human flesh and other reports asking to stop pouring the dirt. We don’t know why it wants human flesh but we don’t want to find out. It also appears to give advice. One day Researcher __ was walking past SCP-8686’s chamber and heard it say to the the day off tomorrow. They ignored it and moved on but the next day SCP 173 broke out and they're where few survivors. Lucky Researcher __ made it out alive and told everyone what happened. This makes SCP-8686 an ominous creature for sure.
