Equestria Girls Octavia Melody
From My Little Wiki
The human version of Octavia Melody is a student at Canterlot High. She appears as a background character in some of the movies and shorts.
Doll & Pony Set
Octavia was released in a doll and pony set. She has black legs, pink eyeshadow, and treble clef under her right eye. Since the set was part of the Rainbow Rocks line, she has a pink stripe in her hair and comes with her cello. One section of her hair is extra long to simulate a tail.
