Rarity has been chosen to design the costumes for the latest play to hit Manehattan, Apple of my Eye. Having little knowledge on the fruity matter, she takes the only mare she knows who can tell her Granny Smiths from her Honeycrisps on a fashion business trip to Manehattan to get started on the designing. While there, an unfortunate mishap leaves the train to Ponyville down, and the two friends find themselves stuck in the city.
