Saddle up for a week in pony paradise! At Sunnyside Stables, each girl gets her own pony to look after and ride for a week. Charlie is devastated when she grows too big for her first pony, Apple, and has to sell him. Her parents think that sending her to Sunnyside Stables for a week will help her move on, but Charlie isn't interested. Can Charm live up to his name and win her round?
