SCP-087 comes from the SCP Foundation collaborative horror project, where it is described as an endless, unlit stairwell descending deep underground, with a faint crying sound luring explorers downward. The story inspired the indie horror game SCP-087-B, where players descend step by step until the entity appears without warning. Clips of those encounters spread through YouTube playthroughs and horror compilations in the early 2010s, and the jumpscare sounds became shorthand for SCP horror online. This second variant is still shared for its sharper, more abrupt scare timing.
