Original Description:
 
Discord was growing bored, since Twilight became Princess of Equestria. He decided to have some fun with the residents of Ponyville. He snapped his fingers, and a pile of one million gold bits poofed right behind him.  
“Gold bits here! Who wants some bits!”, he called.  
Now, every resident of Ponyville knows that you cannot trust Discord and his antics, as when he does something nice to a stranger, there’s usually a catch. Despite this, some ponies like to humor him. Brainstorm was walking by , when he was stopped by Discord.  
“You sir! Yes, you! How would you like a one million bits?”, he asked.  
Brainstorm wasn’t sure, he could use the money, but it’s most likely a trick.  
“What do I have to do?”, he asked.  
“Oh, just play a little game, I promise you won’t get harmed.”, Discord said, in assurance.  
“What are the rules?”, asked Brainstorm.  
“Hold on, before we can begin, I need to ask you a question, would you rather wear a humiliating outfit of my choice, or become your favorite animal?”, he asked.  
Brainstorm was puzzled, he knew the question had to be part of the game, but he didn’t know how. He just had to play along. He thought about his favorite animal, but Discord could leave him as that animal forever.  
“I’ll go with the outfit.”, he said.  
“Good.”, said Discord.  
“Now we need another player.”, Discord looked around, and spotted a random pony.  
“You sir!”, he called to the pony.  
“You look like you could use a million bits.”  
“Uh, sure.”, he said.  
“What do I have to do?”  
“All you have to do is become your favorite animal.”, said Discord.  
“I guarantee, you will be back to normal, when we’re done.”  
Brainstorm became suspicious, Discord didn’t ask that pony about the outfit.  
“Oh, I would like to be a crocodile.”, said the pony.  
Brainstorm tried to intervene, but before he could stop him, Discord raised his hand. With a snap of his fingers, the two ponies lit up, and in less than a second, they assumed their new roles. Brainstorm looked at the outfit he was wearing. It was a filly’s outfit.  
“Well, girl’s clothing is very humiliating for a stallion to wearrr… OH!”, gasped Brainstorm, as he just heard the feminine voice that just escaped his lips. He checked himself, to find a pair of panties, strapped to him. He rubbed his crotch a bit to find that he really IS a girl! His opponent wasn’t much better. he was a crocodile, true, but he was about 2 inches tall.  
“We better get out of here!”, he thought, but before they could leave, Discord levitated them in the air.  
“Hold on!”, he said.  
“You can’t leave just yet, we haven’t even started.”  
“CHANGE US BACK!!”, Brainstorm yelled.  
“RAAAAAAWWWWWWW!!!”, the crocodile said, before quickly closing his mouth. He realized, he couldn’t talk!  
“In do time, my dear, but only if you play my game.”, said Discord.  
“Besides, you still want the bits don’t you?”  
Brainstorm thought about it. The crocodile wanted to call it quits, but he couldn’t say a thing.  
“You promise you’ll turn us back?”, aske Brainstorm.  
“You have my word.”, said Discord.  
“Okay, we’ll play your game.”, said Brainstorm.  
“Horray!”, exclaimed Discord, in joy.  
“Now the rules are.”  
“The young mare, that’s you, must go the rest of the day, wearing only girl’s clothing.”, pointing to Brainstorm.  
“But, you must do it while your opponent goes for a ride in your clothing.”  
“WHAT!?!”, yelled Brainstorm, but Discord clothes her lips.  
“Two, you’re not allowed to take off the clothes, unless you’re changing them.”  
“Three, you cannot remove your opponent from your clothing, on your own.”  
“And four, you may wear a hat, but you cannot hide your opponent in it, because that’s cheating.”  
Discord then turned to the crocodile.  
“As for you.”  
“You have to make her remove you from her clothes.”  
“You’re not allowed to leave her clothes on your own.”  
“Two, you cannot, intentionally, harm her.”  
“That means, no hard biting, or scratching.”  
“Three, if she changes her clothes, you must stay on her.”  
“Four you’re not allowed to hide in her hat, if she wears one.”  
“Five, if you are removed from her clothes, by somepony else, then you must try to get back in her clothes, before the game is over.”  
Discord then directed himself to the both of them.  
“You both are not allowed to tell anypony about the game.”  
“You’ll both have until midnight.”  
“The winner will receive one million gold bits, but the loser will receive THIS!”  
Discord opened a portal to another dimension, that looked absolutely horrifying.  
“The loser, will spend the rest of their life in this dimension.”  
“So, NO cheating! Understand?”, said Discord, strongly.  
The two just nodded, yes.  
“Excellent.”, and he opened the back of Brainstorm’s dress, and dropped the mini croc down the back of her dress.  
“Good luck, every pony!”, he said, and teleported away.  
Brainstorm, landed with a thud.
