Five Nights at Sonic's
Clone Sonic starts on the Show Stage and attacks via the right door. Use the light to check if he's there, and close the door to block him out. If you don't block him out in time, he will jam the door controls. If you flip of the camera while the controls are jammed, he will kill you.
Alternatively, if you run out of power, he will rush to the left door, playing a music box song and then killing you. He will attack in this way regardless of his AI level.
