The engagement of Shining Armor and Princess Cadence was supposed to be the happiest day of their lives. But when Corona comes to call to get a slice of the celebratory Vorpalberry Pie, she puts the entire town under her vegetable loving geas to ensure she gets a slice. It's up to the Elements of Harmony to break the spell, and bring the love of sweets back to Equestria before it's too late, and the Vorpalberry falls into the wrong set of jaws.
