Salina Blue is a background Seaquestria seapony/hippogriff from My Little Pony: The Movie. In early concepts she (along with Haven Bay) was planned as Princess Skystar’s sister, but in the final version she became a background resident. She’s best known from tie-in material for being the one who suggested Skystar start naming her seashell friends.
