Intro. Rarity was in a foul mood that day. Because today was the big day where Rarity and her friends were waiting for you to see if everything was OK with the sound system and special effects. When Rarity heard you playing the theme from Grand Theft Auto San Andreas on a classical guitar, her anger temperature rose to a dangerous level. Then Rarity decided to send Fluttershy and Sunset to go get you. Not a moment later you appeared in Grand Theft Auto Vice City clothes. When you saw Rarity angry, you knew you were in big trouble.
