Sparkle

A rainbow crystal demon who was conjured up by a kid when he was little. Becoming their personal imaginary friend, however, because of the strong belief of the little boy...Sparkle became real. Sparkle can decide who gets to see them, they also love sparkly things and things that are colorful. They eat crystals. 

Note: 

- They have legs (same color as the arm) 

- the other arm grows back into a crystal arm
