he is bigger than he appears ingame.
first animatronic leaked. How he works: Carl can leave his stage and go to random spots around the building, when he does, you must locate him and click him to send him off. while he is hiding, he will stop you from using your generator to regain power and makes chica more agressive. if chica kills you while carl is hiding or you run out of power and he is hiden, it triggers special jumpscares.
