The Elements of Harmony get a well deserved and much needed vacation to one of Equestria's newest summer resorts. When Applejack challenges Rainbow Dash to a swimming race, Dash declines. The problem? Dash doesn't know how to swim. Rarity then takes it upon herself to teach Dash the art of swimming, but can Dash learn to swim fast enough to beat Applejack? (Hinted Rarity X Dash)
