Probably because she constantly eats garbage that was stated to mess up her insides.

Maybe because she's eating garbage and it's start ruining her system

I know this is pretty late reply, but I think the reason she does is because of all that trash eating. It’s damaging her mechanisms

@@76o90 maybe, but in the starting video we see her performing just fine, as well as in the start of the game when we see her playing her guitar through the vents. I personally think that Vanny's control is affecting Chica the most, and also are making the animatronics too active, causing the cracks in their casing we see later in the night.

@@76o90 no it’s because she’s trying to take control of herself cause vanny hacked her

I was considering making all of the animations into one video. But the video would be like 1 hour and 30 minutes long. This was probably a better and easier for people to find.

Called what?
