Cupcake Frosting-The story of one unicorn
About 4 years after Pinkie Pie met Cheese Sandwich, they found each other again and eventually got married. Pinkie later gave birth to a unicorn mare. She was a unicorn because Pinkie's great-great-great-great-great-grandmother was a unicorn. She was a pure white with a light and dark pink mane and tail. She had the brightest pink eyes that seemed to glimmer all the while. Pinkie and Cheese took good care of the mare and she grew up healthy. She became a beautiful young filly. Her eyesight got a bit blurry, so she ended up with small round eyeglasses. On her first day of school, Pinkie tied a bright pink ribbon into the back of the filly's mane;she said it was for good luck.
The young mare found herself constantly going into Twilight Sparkle's library to ask her if she could help her with magic. Twilight agreed happily and taught Cupcake Frosting about everything she knew about magic. She learned quickly and was levitating things here and there.
Frosting started to use her magic to help Pinkie run Sugarcube corner. She found out that she was especially strong in using her magic to help Pinkie frost, decorate, and bake cupcakes. One day, Frosting had made a whole batch of cupcakes using her magic. After she decorated the last cupcake, a bright flash of light appeared on her flank and Frosting was surprised to see her cutie mark. It was a chocolate cupcake with pink frosting, sprinkles and a cherry on top. She was delighted! She told Pinkie and Cheese what she had done, and they were both astonished. Frosting continued to make cupcakes with magic.
