Golden Freddy is one of the most mysterious animatronics in Five Nights at Freddy's, and this clip comes from Golden Memories, a fan-made game built around that character and its haunted atmosphere. Fan games like this keep the original series alive by reimagining its scares, characters and lore for new players, and short sounds from them are widely shared on soundboards and in fan edits. The clip stays popular because Golden Freddy still represents the series at its most secretive and frightening.
