This only applies to the characters that reside in the basement.

The characters this mechanic applies to are, Proto Golden Kitty, and Despair Lockjaw.

If you hear a female giggle, then Proto Golden Kitty has moved, you must find her on the cameras. If she is 2 cameras away from the basement exit(located right behind the player) you must use the primary audio lure, as to her ears, it sounds like the voice of her dead father. It will lure her away from the exit. if you don't she will appear in front of the player and kill them.

If you hear a male giggle, then Despair Lockjaw has moved. You must then find him on the cameras, if he is 1 camera away from the exit, lure him away with the secondary audio lure, As it is hooked into the suits systems, so to his ears it takes on the voice of his friends Anna(Kitty Fazcat) and Micheal(Sugar). If you fail to do so, he will then charge out of the basement exit behind you and leap at you, shoving his hands through your chest and smashing your heart in the process, killing you instantly.
