Sparkle Pop grew up just like any other young unicorn. She was smart, brave, and liked to tackle all kinds of problems. But as she grew older and older, she began to notice that she wasn’t like many of the other fillies and colts in her class. She never found her cutie mark! Because of this, Sparkle Pop felt like a foal all the time, so much so that in her private time since she was a filly, she treated herself like she was a baby. This behavior went with her all the way until her marehood where she continues this practice to this day. She feels that as she never got a cutie mark, it is her destiny to be the little foal she truly is. That is her destiny, to forever be a foal.
