Applejack leaves the farm and heads to the big city of Manehattan to join her Aunt and Uncle Orange, who promised to shape up the little filly into that of elegance. During an evening get-together with some of the other regal Equestrians, AJ tells them how much she loves the city with her new high-society accent, but she causes a raise of eyebrows when she mentions the life she left behind. Thankfully, her awkward moment is interuppted as dinner arrives. But it turns out to be nothing more then a bit of carrot and a bit of corn which resemble garnish more than substantial fare. She quickly grows disappointed of the city life and becomes homesick, missing her simpler farm life and wondering what her big brother and grandmother are up to. Just at this moment she hears a loud bang and sees a beautiful rainbow stretch across the sky towards Ponyville. Applejack makes up her mind and returns home. Accepting her old farm life, realising that it is where she truly belings, her cutie mark appears: a trio of red apples.

Twilight was eager to join the festivities of the Summer Sun Celebration that took place in Canterlot. Seeing the ruler of Equestria raise the sun inspired her to study everything there is about magic. Her parents noticed their daughter's interest and enrolled her into Celestia's School for Gifted Unicorns. The only thing in the way of her dream was an entrance exam she was required to pass. The test was to hatch a dragon's egg, which Twilight failed to perform under the pressure of the exam. Just as she gives up and apologizes for wasting the testers' time, she hears a boom from outside. Inexplicably, her magical energy is triggered. The egg hatches, revealing a purple and green baby dragon. However, she soon loses control and causes chaos inside the exam room, causing the judges to levitate, turning her parents into potted plants, and making the dragon grow to immense size. Princess Celestia, having seen the event from outside, stands next to Twilight and places her hoof on her, making Twilight's magic wear off and returning everything to normal. Celestia compliments Twilight on her raw power, but reminds her that it requires focused studying to control it. She offers to take Twilight under her wing as her new protégé. With her parents silently encouraging her to accept, Twilight says "yes" and bursts into cries of happiness, but Celestia adds one other thing -- she points out to Twilight that a cutie mark, a violet-colored star with five small white stars surrounding it, appeared on her flank. Twilight soon hops around the princess, even more excited than ever.

Rarity was in charge of costumes during a school play. She was praised by her teacher by calling them "very nice", but it wasn't enough for Rarity: they needed to be spectacular. Obsessively trying to craft the perfect clothes, she wonders if her dream of being a fashion designer is fading. Her horn glows soon afterward, literally pulling her away from her house, away from the outskirts of Ponyville. To where, she had no idea. However, she knew that unicorn magic happens for a reason, and it may lead her to her true destiny. After being dragged through the desert and up and down mountains much like a rollercoaster for an entire night, her mysterious journey ended with her stopping in front of... a giant rock in the midst of a plateau. As she furiously laments about why her horn led her all the way to this area, she soon hears a blast, followed by a sight of vibrant colors in the air. The shock waves split the boulder in half, revealing a vein of gems. She used this pile of crystals to decorate the costumes. At the night of the play, the audience watching were in awe of the fillies wearing the bejeweled set. Rarity's inspiration, not to mention her new ability to track down hidden gems, gave her a cutie mark of three blue diamonds.

According to Pinkie Pie, her life was not always as happy as it is now. She worked at a rock farm with her family outside of Ponyville. No one played, or talked, or even smiled. They just worked. After her family went inside for the day, she heard an explosion from the sky, followed by a blast of wind, messing up her straight hair. She then saw a wave of colors, turning the gray world around her blue. It was the first time in her life that she ever felt pure happiness. She was so overwhelmed by the colorful rainbow, that she wanted to "smile forever" and, even more so, wanted to spread this happiness. The next day as her family was going out, she called them into the silo. Her mother questioned what she's doing, revealing that Pinkie's full name is Pinkamena Diane Pie. Inside the silo were party decorations, balloons, streamers, music, and cake. However, as she saw them look at the scene strangely, it almost seemed as if they didn't like it. Taking a second look, she saw their smiles slowly, but surely, reveal themselves and they danced with her. With new-found joy, Pinkie's cutie mark appeared, showing a set of blue and yellow balloons.
