SCP-3000 comes from the SCP Foundation, a collaborative online horror fiction project where writers document fictional anomalous entities as classified files. SCP-3000 is described as an immense serpentine creature living in the deep ocean, and its size and elusiveness have made it a popular subject for horror narration, lore videos and creepypasta-style content. Short audio clips inspired by the creature circulate on soundboards and social video platforms, where creators reuse them to suggest an unseen deep-sea threat without showing the monster itself.
