Hammy is an indigo Sprite, and as such is a close acquaintance of Indigo Doll. Hammy is the Sprite in charge of all the indigo Color Crystals. Hammy apparently got his name from his love of acting. While some find him overly dramatic, Indigo appreciates his personality. Hammy is in charge of color crystals that Rainbow Brite uses for things such as blueberries and lakes.
