Chapter 1: Chapter One: Beginnings
Pinkie, Inkie and Blinkie didn't always live with their mother. We know about the rock farm, the party and their connection with each other. But what happened after that when they were grown ups? Pinkie had no idea about her sisters. But now she will know about them...
"Pinkie, will you keep that down?!" shouted Rainbow Dash. Pinkie was once again playing her guitar in Ponyville's town center. "I'm trying to read Daring Do's second book!" But a lot of ponies seemed to enjoy it. Pinkie played for about an hour and stopped. "Rainbow Dash, I love playing on my guitar!" she said happily. Rainbow Dash had flown away after a few minutes of hearing the music. Pinkie continued playing.
