Moon is the the nighttime and security counterpart of the daytime animatronic Sun. He is a jester or clown-themed animatronic with a face like of a grinning crescent moon, the right-sided half of his face being colored black, making the crescent moon half of his face a white color. On his head, he wears a sleeping cap that is blue in color and patterned with bright yellow stars, and the end of the cap is a bell. There is also a small latch on his back which connects to a hook and flying wire.
