This bug occurs because the sound clip is the same sound that Bonnie or Chica make when in the corners during Night 4, 5, Night 6, and the Custom Night.In the first Five Nights at Freddy's game, if a visual hallucination occurs while Bonnie or Chica are in their respective hall corners on Night 1, Night 2, or Night 3, the sound clip will continue to play until they leave the corners.When entering an area or booting the game, a blueprint of one of the four main animatronics will randomly appear on the screen for a minute or two. The condition that mutes the sound requires Bonnie or Chica not to be in the corners, so the sound still plays when it's supposed to on Nights 4-7.
