Original Description:

“Starlight Glimmer bets Trixie she can’t make an entire magic show with tricks revolving around passing gas. Trixie happily takes up this challenge and agrees.”

“You really think you’re a great magician?” Starlight asked.

“Only the greatest magician in Equestria,” Trixie said. “Nobody possesses such incredible magical prowess as I the great and...”

PFRRRRRRRRRT

Trixie’s sentence was cut off by a fart escaping her flank.

“...well, flatulent, Trixie.” She chuckled.

But Starlight didn’t chuckle. Instead, a devilish grin slowly crept across her face. A brilliant, evil, wonderful idea just cracked in her head.

“Would the greatest magician in Equestria be willing to make a bet?”

Tricks smiled. “Lay it on me.”

“I bet you can’t make an entire magic show that centers entirely around...” She pointed a hoof at Trixie. “...your farts.”

Trixie scoffed. “Please, Starlight. That’s child’s play.”

Starlight smirked. “And I think I know just the gal to help us...”

“And I mean, gaseous emissions are kind of your species’ thing, isn’t it?”

Ember thought. “Yeah, it’s true, us dragons love our burps and farts. But we don’t try to make flashy spectacles out of them.”

Starlight looked confused. “But, don’t you guys have farting and belching contests all the time?”

“Yeah. Competing to have the loudest, grodiest ones possible. Turning it into fancy, frilly magic tricks magic tricks would ruin the point. Besides, I doubt you ponies could handle a dragon’s fart. If I helped you out with my own gas I’d probably kill you.”

Trixie pushed Starlight aside and walked to Ember confrontationally. “You wanna bet?” Starlight tries to signal to Trixie that this was a bad idea.

Ember looked at Trixie and rolled her eyes. “Fine. You wanna see what our farts are like? I’ll give you a tiny little taste.” Ember turned back facing the two unicorns, lifted a leg and pooted.

Even from a relatively small fart the stench was corrosive and awful. Starlight and Trixie coughed and gagged on the stench.

“Yep. That’s the power of a dragon’s fart and we’re proud of it. No offense, but I doubt a couple of ponies could handle long-term exposure to that, let alone what we’re really capable of.”

The Opening Trick: Who Farted?

Starlight uses a broadcasting spell right behind Trixie’s ass. During her opening speech, Trixie rips one and the sound happens somewhere in the audience.

Trick: Farts of Flame
