Springtrap first appeared in Five Nights at Freddy's 3 as the decayed form of Spring Bonnie, the golden rabbit suit inhabited by William Afton, and quickly became one of the series' most recognisable villains. Audio connected to the character spread through gameplay clips, fan edits and horror compilations, where his slow, distorted presence stood out from the series' louder jumpscares. It remains popular because Springtrap represents the long-running story behind the games, so even a short sound instantly signals danger, decay and a familiar FNAF threat to fans.
