The Canterlot 'Warrior of the Sweet Tooth' pastry eating contest, has been a quinquennial (def: every 5 years) event in Equestria for the last 400 years; with Princess Celestia, its 78-time defending champion. Now for the first time in centuries, her highness has a worthy opponent in her path. Miss Pinkamena Diane Pie.
