"Well," remarked Princess Luna, surveying the damage before her, "we would have words with thee, Discord."
"C'mon, Moonbutt," chuckled Discord, spirit of Chaos. "You know Princess Celestia's birthday deserved no less than an absolute belter. The last three were so STUFFY."
He gave Luna a rather pointed look. "Also, it was Fluttershy who suggested I take care of entertainment for the day. Take it up with her."
"I shall," ground out Luna. "And now the entire southern tower is now completely flooded in custard."
Discord rolled his eyes. "Yes, I know. I was there. I promised no Chaos until the party was over. I'd like to go on record as saying it's not my fault the guests weren't fast enough to escape."
"Is that right?" Luna sighed. "Now then Discord, if you could rid all twenty-five stories of this tower of custard? Several ponies will need those rooms later."
Discord looked over at the stone monument he and the Princess were hovering at the top of. He could just about make out a green pony from what appeared to be the sixth floor jumping out of one of the windows, covered in yellow goop and screaming her lungs out.
Chuckling at the sight, he paused. "Seems a shame to waste all this, really..." Discord turned to Luna. "Say, how about we make a game of it?"
"A game?" Luna protested. "Discord, we need this tower back!"
"And you will," Discord raised his clawed hands up. "if you play."
Luna sighed. Truth be told, without the Elements of Harmony, there was very little they could do to actually stop Discord. True, his friendship with Fluttershy reined him in somewhat, but on the days when he was especially bored, it was hard to tell what he'd do next. He did at least promise to keep the Chaos to things that could be easily fixed.
"C'mon," pleaded Discord. "You slept through the party. Didn't even get to the party games part. And I had to be on my best behaviour until the end. Let me have this. Let YOU have this."
It took about a minute of silence, before Luna's face pulled a resigned look. "What are the rules?"
"Aw Moonbutt, you're the best!" cheered Discord. He clapped his hands together. "So! Here's how it goes. We've got twenty-five floors of custard to power through. You and I will take turns draining floors of custard, either one at a time, or three or four at a time."
"And how, pray, will I do that?" Luna asked. "Your Chaos is resistant to all my best banishment spells."
"With this." And with that, Discord conjured up a small plastic straw out of thin air with a snap of his fingers, and handed it to Luna. The straw was striped red and white.
Luna looked at the small plastic tool. "I will assume there's more to this. My stomach capacity has limits."
"Oh, it's special," Discord grinned. "Suck on it once, and it'll vacuum up all the custard in a room, and vanish inside the stomach. Hope you like the taste of cola, by the way."
"Cola?"
"Well, yes," Discord said, as though it were the most obvious thing in the world. "It's CHAOS custard. It won't taste like REGULAR custard. That would be dumb."
"Of course not," Luna said dryly. "And we are to take turns draining each storey of custard until it's entirely gone?"
"Basically," he confirmed. "But you win by draining the custard level to EXACTLY zero. No going over, princess. Oh, and you're not allowed to pass. You have to drain at least one storey every turn."
Luna paused. "So if I drain the custard exactly, I win? And what happens, pray, should I lose?"
"Then I'll flood the towers with custard again, and you'll have to start the game all over."
"WHAT!?"
"It's for the best!" Discord protested. "You just need to win once! That's all! Then I swear I and all my custard will be out of your mane!"
Deep down, the Princess of the Night knew she didn't have much of a choice. Refusing to indulge Discord and having to drain all the custard manually would take far too much time and resources. It stunk of a shell game, but she decided to bank on Discord's restraint regardless.
"Win just once?"
"Win just once."
Luna grimaced. "Restore everything inside to pre-custard condition afterwards, and I'll accept."
"Oh, I knew you'd say that," Discord smiled. "Tell you what. For being such a good sport, I'll let you go first. Take it away, Moonbutt."
