On one of her rare (very much so) days off from royal duties, Princess Twilight just wants a little time to herself without having to resolve any crazy shenanigans of her subjects (magic, science, magical science, and the always informative sex-ed). Of course, such a blessing is mere wishful thinking in Ponyville.
Discord drops by looking to show the lavender alicorn his newest invention; Chaos Ball, a game for the whole family which combines all the greatness of bowling, chess, and dodgeball (hail the almighty bag of randomness). She doesn't want to play, of course, but the spirit of chaos has ways (many involving five-eyed, mini-skirt wearing, winged lizard/squirrel hybrids) of getting ponies to do what he wants.
Can Princess Twilight beat the draconequus at his own game, or will she suffer permanent psychological damage from playing?
