Marionette is an animatronic who saves people like saving the kids when they are about to get killed by Purple Guy. Was killed by Henry and was an important character in Old Sport's life.
Also, if you fail to wind the music box, she will either:
A: If you are not in the suit, rip off your testicles.
B: If you are in the suit, uses THE TICKLE FINGERS to trigger the springlocks and kill you.
The only thing that is known about Marionette is that he only saves someone when someone tells him what is happening.
Marionette is the smartest animatronic. He sometimes chooses the wrong evil then other people will think that they are evil.
