These characters appear all too briefly in the episode "Princess Problems" on the cartoon my little pony tales. They are horses of royalty, and are twice the size of adult ponies.
Furthermore have errors in design in the animation . In the first scene no seen cute mark, his face has a white part, and is not seen his tail. Another scene, shows her cute mark is a crown, her face is totally brown and its tail is short.
Originally made in ms paint now remastered in sai.
