Equestria Girls is the name of a product line associated with Generation 4 of My Little Pony. The product line's backstory revolves around an alternate world where the characters of My Little Pony: Friendship is Magic appear as humans, with some pony-like features. The main characters have been released as humanoid dolls, and usually include fashion accessories.
To promote the line, two full-length movies have been created. The first, My Little Pony: Equestria Girls, was released in June 2013, and featured Twilight Sparkle traveling to the human world after her Element of Magic tiara is stolen. The sequel called Equestria Girls 2: Rainbow Rocks, is scheduled to be released in September of 2014, and revolves around a band competition that the main characters compete in. While the movies are related to My Little Pony: Friendship is Magic, the events of the movies have no bearing on the tv series.
My Little Pony: Equestria Girls
My Little Pony: Equestria Girls, takes place sometime after the Season 3 finale, "Magical Mystery Cure". Twilight, and her friends travel to the the Crystal Empire where Twilight is to attend her first princess summit. Twilight is shown to be struggling with her new-found alicorn status, and the potential responsibilities of a princess. While Twilight is sleeping that night, a unicorn, Sunset Shimmer, comes and steals Twilight's crown, with the intention of replacing it with a fake. While Twilight discovers the attempt, she is unable to stop the unicorn from traveling through a mirror, actually a portal to another world, after the crown falls through it.
Twilight is forced to enter the other world to retrieve her crown, as it is the element of Magic and key to the defense of Equestria. In the other world, Twilight becomes a teenage girl, and is must cope with her new body and lack of magic as she navigates the high school Sunset Shimmer attends. There, Twilight learns that to retrieve her crown, she must become Princess of the Fall Formal. Twilight then works with five girls who closely resemble her pony friends to win back her crown and return to Equestria. However, at the same time, she must deal with the machinations of Sunset Shimmer, who wants the Element of Magic in order to use its power to take over Equestria.
Equestria Girls 2: Rainbow Rocks
The second movie, Rainbow Rocks, is scheduled for release in Fall 2014. The main plot appears to revolve around the human versions of the Mane Six entering a band competition. In advance of the film, animated shorts featuring the main characters were released.
Merchandise for Equestria Girls takes the form of human dolls based on the Mane Six; supporting characters have also been released. The dolls are mostly humanoid, but retain several pony-like features: hair and skin colored to match their pony counterpart, pony ears, a longer lock of hair meant to resemble a a pony's tail, and in the case of dolls based on Pegasi or Alicorns, a pair of wings which attach to the back. Each doll usually comes with at least one outfit and a few accessories, though some releases feature more. Some dolls have also included either a molded figurine or a Playful Pony toy of their pony counterpart.
Dolls released in conjunction with the first movie have a marking on the cheek resembling their pony counterpart's cutie mark. These dolls do not have feet; instead, the dolls shoes attach directly to connectors on the feet. A brush that looks like a stylized pony is included. Basic dolls had limited articulation, while others had articulation at the elbows and knees.
Dolls released as part of the Rainbow Rocks series feature multicolored streaks in their hair, and a marking over one eye based on their pony counterpart's cutie mark. These dolls feature more traditional feet, and usually have music oriented clothing and accessories.
