It's the Friendship Is Absurd parody of Equestria Girls you never asked for, but you're getting it anyway! Unhappy with the result of her recent ascension, Sunset Shimmer heads to the Crystal Empire to see about fixing it. Much to her dismay, however, she instead ends up getting drawn into a completely unrelated subplot when her Element of Irony gets stolen and taken to an alternate world. It’s up to her to navigate this strange plane and get the Element back before time runs out… or before she just loses interest, whichever comes first.

Takes place after Chapter 21 ("Magical Mystery? Sure!") of My Little Pony: Friendship Is Absurd.
