One Night at Flumpty's began as a parody fan game inspired by Five Nights at Freddy's, created by developer Jonochrome and built around the egg character Flumpty Bumpty. The third game arrived in 2021 and was presented as the final entry, mixing cute cartoon designs with sudden horror beats. Clips from its voice lines later circulated in fan edits, streams and soundboards, where short, recognisable lines could be reused out of context for entrances, turn swaps and dramatic reveals in gaming videos.
