The sound Withered Bonnie makes when attacking the player. This same sound is played when any animatronic attacks the night guard, with Golden Freddy and BB being the only exceptions.
The sound heard when Withered Bonnie is inside the Office. It begins at any random point throughout the audio, and only plays for a few seconds before abruptly ending. This sound is also used by Withered Freddy, Withered Chica, Toy Freddy, and Toy Bonnie whenever they enter the Office.
