Sweetie Derelle, the alternate reality Sweetie Belle, has arrived in Equestria to save everyone. That includes driving a bus full of orphans at high speed through Canterlot to make sure it doesn't explode. Also into Canterlot Castle. Specifically Celestia's Bedroom. Along the way, the hero everyone deserves known as Donut Joe will help the transdimensional trashcan-mouthed monstrosity complete her mission.
But can the city, and Rarity, learn to love this goggly-eyed savior from another dimension?
No. Probably not.
