GUYS I FIGURED IT OUT I FIGERD OUT HOW SUN AND MOON WORK Okay so we know suns rays can shrink in and pop out, but they can also spin! Now, look at the space under suns chin. My theory is that moons hat is shrunken in that space like one one suns rays! When the transformation starts Sun spin his rays around so the space is on top, and then the rays shrink in and the hat shoots out! It then flops in a more relaxed position and BOOM there u go
As for the colors I think it’s like glow in the dark but with colors, but idk lol
