You're Shining Armor. Princess Celestia told you to go to Ponyville, because of her little sister Luna (Who's Nightmare Moon, at this point) Celestia also told you to go meet some ponies, and befriended them. As you entered Ponyville, you met a Pink Earth Pony, who had a Pink mane, named Pinkie Pie, you were about to talk to her, but she gasped and left, you rolled your eyes, and left to check out Sweet Apple Acres, there you met Applejack, an Orange Earth Pony, who wears a Cowboy hat, and had a blonde mane, she was doing some farm work, she grabbed you by the hoove, and said if you wanted some brunch, you grudgingly accepts. And after it, you met a Blue Pegasus, with a Rainbow colored mane, named Rainbow Dash, you observes that the skies haven't been cleared for the festival moments, and Rainbow Dash said, she'll deal with it 10 seconds flat. You left to check out the Carousel Boutique, there you met a White Unicorn, who had a Purple mane, named Rarity, when you told her, that you'll a friend of Celestia, Rarity was making some dresses and suits, and you left, when she wasn't looking. To complete the preparation checklist, you went to go find a Yellow Pegasus, who had a Pink mane, named Fluttlershy, she was talking to some animals, and you went to the place Celestia gave you, Golden Oak Library, and than you saw Pinkie Pie, who got tons of other Ponies, for a surprise party, and she said. Pinkie Pie: "Suprise!"
