The Mints are the smallest fairies in Sugar Valley with perhaps the biggest job, especially in the winter months. The Marshmallow Run sledding competition is the highlight of the winter, but this year it's Dash the Mint Fairy's responsibility to make a new candy cane throne for Princess Lolli. But she is more interested in going marshmallow sledding. When Mogu the Sour Troll challenges her to a sledding race, the fate of the peppermint sticks hangs in the balance. Can Dash defeat the troll and complete the throne?
