My Little Pony: Equestria Girls

When her crown is stolen from the Crystal Empire, Twilight Sparkle pursues the thief, Sunset Shimmer, into an alternate world where she finds herself turned into... a teenage girl! To regain her crown and return to Equestria, Twilight must learn how to fit into this strange new world and defeat Sunset Shimmer in a competition to become crowned Princess of the Fall Formal at Canterlot High. Luckily, she’ll have the assistance of Spike and five teenage girls who remind her of a certain group of ponies back home.
