So Twilight has already told Celestia that she's a dum dum, tried to put a guard in time out, slid down the hallway in that guard's armour, threw a flower pot at Celestia, threw a paint balloon at one of Celestia's guests, sprained that guests hoof, told Cadance that she was a dum dum, burnt down the Canterlot Castle...you get the idea. So what next?
