Ok this is my first page ever so bear with me.

So I have a theory to compose to all of you.

In the Sister Location trailer you hear Baby saying don't hold it against us and you don't know what we've been through. So what if the

animatronics are in a lab! They are being tested on! And who is behind this? The Purple Guy! He knows that there is children's souls trapped and are torturing them and enjoying it. And why are they trying to kill you? They want to escape and you are stopping them not knowing what to do! Thanks to Game Theory (mat pat) for giving me the idea. Check them out on YouTube and check out their Sister Location video and it will all fit in! Also you should see the treecicle fnaf theorys.
