Squidward’s Suicide is a creepypasta framed as a network intern recounting an unreleased preview tape of a popular cartoon. An episode that begins normally grows steadily distorted, with blood streaming from a character’s eyes and horrific, realistic scenes cutting in. A familiar cartoon turns into a nightmare.
This tale cemented the formula of the subgenre called the "lost episode." Built on the premise of having seen a piece of footage that never existed, it turns familiar, beloved content into a channel for fear. Its engine is the claim to have seen a record no one else can verify.
