The series stars a unicorn pony named Twilight Sparkle, who is a pupil of Equestria's ruler Princess Celestia. Seeing the young pony buried in books, the princess sends her to Ponyville and gives her the task of making friends. Along with her assistant, a baby dragon named Spike, she becomes friends with the tomboyish Rainbow Dash, glamorous Rarity, hard-working Applejack, timid Fluttershy, and hyperactive Pinkie Pie. Together they explore the ins and outs of the town and solve various problems. Each episode usually ends with Twilight Sparkle reporting back to Celestia on some aspect of friendship that she has discovered in the process, either through her own experience or by watching the other ponies.
