Selma Gallman (AKA Selma Galwaugh) is the granddaughter of the man who owns Galwaugh Farms. She is commonly known for falling off of her saddle, and Massie calls her "Fall-a Abdul". She appears only in Massie, a summer collection book.
Massie glues Selma to her saddle at a Galwaugh Farms annual horse race, so Selma doesn't fall off her horse and ruin the alpha's winning streak. Selma clears the jumps with no problem, but later Massie's cheating is exposed and she is kicked out of Galwaugh Farms.
