Moon is a grumpy yet smart moon themed animatronic who’s brother is Sun a sun themed animatronic, the two brothers mortal enemy is Eclipse who is an evil dark version of Sun, Eclipse is their mortal enemy because he’s always trying to make their lives a living hell, one day Eclipse someone threatened Moon into meeting him in a secret sketchy place or else bad things would happen and then used his body switch ray on him so he could look and sound just like Moon while Moon looks/sounds like him
