Jack-O-Chica first appeared as a Halloween variant in Five Nights at Freddy's 4 in 2015, a fiery reskin of Nightmare Chica with a jack-o-lantern theme. The character returned in Five Nights at Freddy's AR: Special Delivery during its Halloween events, where animatronics attack the player in augmented reality and a failed shock triggers the jumpscare. Clips of that attack were ripped and shared on soundboards as a generic FNAF jumpscare scream, and editors keep using it for short horror memes because the blast is instantly recognisable to series fans.
