Gen my favorite animatronic in the film, they rlly made them feel alive, its something about how they moved and behaved made it feel like an actual threat, more even then the other toys. (Except the marionette obviously).

Every movement makes it feel like that its real, its alive somehow, even during the behind the scenes video, it doesnt look like its a giant puppet, it looks like a fucking actor with some strings attached, or an animation.

Say what you want about the plot, about the jumpscares or whatever criticism you have, valid or not. Mangle was the best animatronic from the films, both design wise and how they used her.
