Raritwi wracked her brains for ideas. Who would be twisted enough to do this? Sombra? Too uncreative. Tirek? He'd want slaves, not twisted sex creatures. Suddenly, she realized who it was.

"Discord!" She shouted.

"Speak of the Discord and he will appear!"

Raritwi leapt several inches off the ground in shock, wings beating uselessly. Discord stood in the center of the library, an innocent shit-eating smile spread across his twisted features. Slowly, the grin melted away, leaving a grey puddle on the floor, and replaced with a look of utter confusion.

"Princes... Her... Rarity... What the-" He was cut off as Raritwi zapped him with her horn. "What is this?!"

"Just a shrinking spell, dear. I'm afraid I know all about your little game, and I'm giving you one chance to fix it before I use you to fix it myself," She gave him a dead serious glare, "And I will USE YOU, make no mistake."

Discord groaned and clutched his gut as he shrunk several inches. "What? Does the fatty want a fat friend?" He chuckled, feeling his claws sink into his slowly bloating belly.

"No, no, that's just your waste. I do hope you haven't eaten much today, because you're about to expel it all at once, and Spike just cleaned this floor yesterday!" Raritwi glanced at the drying pool of shit near the ruined treadmill, "Actually, go stand over there. I've no idea whether you'll burst, but I shan't allow you to further sully my #1 assistant's hard work!"

Even as she levitated Discord's shrinking, rounding body over to her own mess, his anus began to slide open. Discord grimaced, obviously not wanting to debase himself. Suddenly, after losing another foot of height and gaining another around the middle, he bent over and screamed. A slurry of neon pink and orange shit spewed out, along with two intact rolls of toilet paper.

Raritwi's horn lit up again, sealing his anus shut. "Now, now, I'll be needing samples if I'm to cure this," she said, summoning a number of buckets and sample trays, as well as a jar. With a simple spell, she separated his expulsions by color and texture, along with the blood beginning to leak from his ears. Perhaps she should've prepared more beforehand.

"P-pweesss!" Discord shouted, distorted by the rush of air flowing from his lungs, "I dii'n do i*uurrp!"

He was cut off by a burp, the first of many as his lungs struggled to expel excess air. He couldn't scream as his insides, at long last, began to rip open and flood his body with filth that simply couldn't fit his decreasing size. His arms and legs bloated, his cheeks became overfull as shitty vomit spewed forth from his mouth like a firehose.

Blood and bile leaked from every orifice. What few alien organs inside him that still worked, shut off one at a time. Finally, his body could take it no longer, and with a cartoon explosion, he burst. The top of the jar popped off from the sheer force, spraying the walls and ceiling with multicolored filth. Bits and pieces of his crushed skeleton shot out like bullets and embedded themselves in the walls around the room, but Raritwi paid it no attention, even as the window behind her shattered.

"Eugh," She gagged, "Spike! Where are you?!"

Author's Note

I wanted to write about a shit explosion, and Discord was never my favorite character, so...
