Tired of always having Twilight come to Canterlot every time she needs to retrieve the Elements of Harmony, Celestia decides to expedite the process by sending Twilight a magical amulet that will allow her to absorb all the Element's powers at once, turning her into a magical girl who fights monsters and wears skirts that are much too short. There's just one problem... Spike's the one who ends up making the contract, not Twilight. So, with Twilight taking the back seat, Spike is forced to take up the hero's mantle—and skirt—and fly to Canterlot to save the city from a massive tentacled beast and seal it back inside the magical card from which it escaped.
