The pretty seapony/Hippogriff in our fanart MLP cursor is Princess Skystar, who appears as a supporting character in My Little Pony The Movie and a central character in the chapter book Beyond Equestria: Fluttershy Balances the Scales. She is the princess of the underwater kingdom of Seaquestria and the daughter of Queen Novo. Princess Skystar is depicted as very cheerful, bubbly, quirky, and talkative. She is also pretty imaginative and creative, making various trinkets and imaginary friends out of seashells.
