The Barbie Adventure VI: Barbie and the Magic of Pegasus

Princess Annika loves skating and has recently adopted the polar bear cub Shiver. Unfortunately, her overprotective parents don't want her, Sunset, Applejack, Rarity, or Pinkie outside skating again. After all, not only is Rainbow Dash, Twilight, and Fluttershy are missing, and according to Pinkie's movie knowledge, Brietta, an older sister Annika is unaware of, is missing as well. However, today was Annika's birthday, and she sneaks out with her friends to celebrate at the rink with everyone. It's around that time that the sorcerer Wenlock strikes, coming in and asking for Annika's hand in marriage. When she refuses, he proceeds to turn everyone but Annika, Shiver, Sunset, and Applejack to stone, and says that if Annika doesn't marry him in three days, they're stone forever. Quickly, two pegasi and an alicorn fly in scooping up the three humans. In shock, they realize that Annika is riding a Pegasus (Brietta), but the more horrifying discovery is that Applejack is on Rainbow Dash and Sunset is on Twilight.
Together, the three ponies and humans (and Shiver) fly to Cloud Kingdom, where they meet the queen Rayla, and explains that Wenlock had transformed Brietta, Fluttershy, Twilight, and Rainbow Dash to ponies, with Twilight being an alicorn despite having transformed into a unicorn just three movies before. The only way to break all of Wenlock's spells is to create the Wand of Light, created by a measure of courage, a ring of love, and a gem of ice lit by hope's eternal flame. The humans travel with the ponified Equestria Girls and Brietta to meet Adian in the forbidden forest, who agrees to help them after a reluctant meeting between him and Annika. Can they build the wand and reverse the spells?
