Thats what happened to Twilight and her friends Rarity, Pinkie Pie, Rainbow Dash, Applejack,and Fluttershy as they has been kidnapped by Flash and his friends/housemates (Fancy Pants, Big Mac, Carmel, Cheese Sandwich, and Soarin) and is stuck there until spring.

Spike is starting to wonder what is the meaning of life because he never can bedazzle Rarity.
