Friendship is Magic (Part 1), Episode 1 of Season 1

     The episode opens with a book telling the tale of two royal sisters who ruled the land of Equestria together. The elder sister was responsible for raising the sun while the younger would bring out the moon at night.

     Seeing the ponies of Equestria enjoy the day but sleep through the night, the younger sister grew jealous and resentful, until one night, she refused to lower the moon. Full of  jealousy, she turned into a wicked mare called  Nightmare Moon. Because Nightmare Moon wouldn't let the sun rise, the elder sister trapped her with artifacts called the Elements of Harmony. Twilight Sparkle, the pony who is reading this book remembers something and rushes home to find out about Nightmare Moon, rejecting a request for a party.

            When she returns she reads that "The Mare in the Moon", or Nightmare Moon, is to be freed from her imprisonment on the thousandth year of the Summer Sun Celebration which occurs "the day after tomorrow". With the help of her friend Spike she sends a letter to Princess Celestia, warning her about the return of Nightmare Moon.

      When Twilight gets the letter back, it tells her to go to Ponyville and check on the preparations for the Summer Sun Celebration. Princess Celestia tells her to make some friends, and Spike also urged for Twilight to  make friends but she just pretended she didn't have time.

     At Ponyville, Spike sees a pink pony ( Pinkie Pie ) and tells Twilight to make friends. Just when they met, Pinkie Pie  jumped, gasped, and then ran away. Twilight, confused moved on.

     Twilight and Spike arrive at Sweet Apple Acres, an apple farm where the food apple farm where the prepared. There they meet Applejack, as well as her large family which includes her brother Big Macintosh, sister Apple Bloom and Granny Smith. Eager to get on with the job, Twilight initially turns down the offer to stay for brunch but the disappointed faces cause her to change her mind.

     Next, they meet Rainbow Dash, a pegasus pony in charge of keeping the sky cloud free. After accidentally crashing into Twilight and sending them both into a mud puddle. Dash's attempts to clean her up result in messing up Twilight's mane, which Dash and Spike both find hilarious. Rainbow informs them that she wants to join The Wonderbolts, an acrobatic team. She then proceeds to clear the sky in just 10 seconds, leaving Twilight astonished.

      Next on the list is decorations, which is under supervision by a unicorn called Rarity.Once Spike saw Rarity, he was lovestruck. Rarity did not care about Spike goggling but instead fussed over Twilight's messy mane and tail. While Rarity was dressing up Twilight, she asked her where she was from. Of course,  Twilight replied Canterlot. Hearing this, Rarity insists that they will be best friends because Canterlot always  has the latest fashions.

      The final item on the list is music, which is being taken care of by a pegasus pony conducting a choir of birds. Twilight's attempts at conversation are met with muffled words and adorable squeaks until she sees Spike. Having never seen a baby dragon before, Fluttershy is full of questions and Spike ends up regaling her with his life story, much to Twilight's dismay.

               Arriving at the library where she is to stay while in Ponyville, Twilight is greeted by a surprise party organized by Pinkie Pie, the pony she had met when she first arrived in town. Not in the mood for partying, Twilight retreats to her room until the start of the celebration. As the Mayor introduces Princess Celestia, the crowd is shocked to find she has vanished. Everyone is scared except for Pinkie who thinks she is hiding.  Instead, Nightmare Moon appears from a cloud of smoke, announcing that she will cover Equestria in eternal night...
