The Barbie Adventure X: Barbie as the Island Princess

Now knowing of not only the discovery of the geodes, but the potential theory that there's more to them than originally thought, the Equestria Girls have more of a motive to keep going through the Barbie movies. This time, only a few end up on the island where a girl by the name of Ro has spent the last ten years living on, with only memories of her life on the island, her first memory being a storm that she couldn't recall all the details of. Sunset, Fluttershy, and Applejack are the only three that end up on the island with her, and they're quick to help her begin to try to uncover the secrets of her past, along with meeting Ro's island friends Sagi, Azul, and Tika.
Fate takes a turn when the Prince Antonio arrives to the island on an expedition. Finding the girls, he brings them back to his kingdom with Ro's animal friends, and Ro is introduced to society for the first time in years. The seven girls are reunited, but not before things begin to take a turn: Ro and Antonio may have begun falling for each other, but he's now arranged to marry the princess Luciana, who's mother, Queen Ariana, had her own plans for the kingdom.
And she plans on using the islanders as the scapegoat.
