A chance encounter with the regal princesses gives Sweetie Belle the opportunity of a lifetime. To be a princess, even if only for a day. What does she want to do? Maybe rule Ponyville, or enjoy a fancy dinner with important ponies. Nope, all she wants to do is help her friends and herself get the one thing they most covet, a cutie mark! Of course, just because your a princess doesn't mean your unstoppable, or know how to fly right away.
I'd like to thank and credit rainbowdash1 for both the idea and helping me on the writing process.
