To prove this i will be comparing the puppet to the only robotic characters in the franchise who is known to not have an endoskeleton, Golden Freddy and BB, aswell as the rest of the animatronics that do have them, but only to compare functionality of not having an endoskeleton and having one. To start let's get som ething out of the way. I'm not saying the endoskeleton in the puppet is like the one's we've seen in the parts and service room of FNAF 1 or the easter eggs in the vents or by the prize corner in FNAF 2, but these endoskeletons are for the animatronics not the puppet. As we all know the puppet was like nothing else in the franchise until sister location, so as a unique animatronic what's stopping it from having it's own special mechanical system. Now before you start talking about strings making it move, i doubt the company would rig a wire system all the way to the office, or the dead child moving it that's where we talk about Golden Freddy. We know Golden Freddy is possessed just as the others are believed to be, but unlike the other animatronics Golden Freddy can't move his limbs. he can only teleport from room to room instead of walking, and the puppet can move run from room to room. Yes the puppet can move its limbs we an see it run for a split second in the cams of FNAF 2, and we see it noodle leg it's way to us in the VR game, and in its FNAF 2 jumpscare it physically jumps and spreads it's arms out like Withered Foxy's jumpscare in the same game who we can see the endoskeleton of showing through his withered suit. With all of this evidence i don't know how else the puppet would be able to move around if it didn't have an endoskeleton of its own. If you guys have any other idea's for how the puppet would move the way it does if it didn't have an eendoskeleton, please let me know in the comments?
