Jack 'O Moon's appearance is similar to Moon's shape, but has some key differences except he sounds like moon sometimes. The crescent of his face is orange, similar to a Jack-O-Lantern, and the other half is a dark purple/blue-like color. His eyes are brown/dark orange, with white pupils, and a white grin. His model most likely has the ability to have a glowing yellow grin, similar to the canon model, but currently that is unknown. His body is shades of gray, darker browns, and oranges.
