Welcome to my comparison review between the My Little Pony Friendship is Magic s Equestria Girls and Equestria Girls 2 Rainbow Rocks. In Equestria Girls Princess Twilight Sparkle must team up with human versions of her friends to defeat super mean girl Sunset Shimmer. In Rainbow Rocks Twilight returns to the human world to do musical battle with 3 wicked sirens known as the Dazzlings.
