Equestria Girls Watch Friendship Is Magic

Set after the events of Rainbow Rocks.

Following two encounters with Equestrian magic, the girls (except Sunset) and the rest of Canterlot High's students and teachers find themselves increasingly curious about the princess from another dimension, Twilight Sparkle.

They now have the opportunity to learn not only about Twilight, but also about her world, all thanks to the mischievous actions of a certain Spirit of Chaos.
