I really wanted to share this because while this piece of audio is on the Five Nights at Freddy’s wiki, I haven’t seen anyone else upload this audio on its own, and maybe not everybody’s noticed this yet.
Please be aware that it WILL scream when you click play! But I added a fade-in at the beginning to make it less surprising.
In-game, the scream is cut off when the screen goes to static, so all you really hear are the first few seconds that sound like a mechanical screech. But when the entire audio clip is played, you can clearly hear it’s the scream of a child.
The disturbing implications support many fan theories, including my own.
