Sunriser
Sunriser is a pink, non-talking horse introduced in the episode “Horse of a Different Color”. She has a white heart on her forehead, and seems to have a crush on Starlite. She is very shy at the beginning and won’t let anyone ride her except Rainbow Brite. The Sprites gave her the name “Sunriser” since she came out in the early morning to watch Starlite. In the cartoon series, Sunriser didn’t belong to anyone and only let Rainbow Brite ride her once. However, the merchandise boxes show Tickled Pink riding Sunriser and say “Tickled Pink’s fun-loving horse.” In the 2009 release, her hair is pink with yellow-gold highlights and the white heart on her forehead has been changed to a golden sun.
Shimmer

Also appearing in the movie, Orin is an ancient white sprite from Spectra. His origin is obvious from the spheres on the ends
