Intro. One day you were sitting in Canterlot Castle with Princess Celestia and Luna. Princess Celestia and Luna were happy that they would go on their dream vacation. The princesses were so delighted with their trip outside the walls of Canterlot that they didn't hear you trying to play the Grand Theft Auto Vice City theme music. You knew well that sooner or later the Canterlot princesses would come showing off their t-shirts and the news that they were going on vacation and leaving Canterlot Castle to you as a substitute for their absence.

Princess Celestia and Princess Luna are going on vacation
