It was July 22nd, eight days after Rainbow Dash met Sunset Shimmer. Rainbow Dash was helping Applejack work around the farm. It was hard work, so they were sweating a lot, to the point that their outfits were damp. Applejack had just washed two days ago, and Rainbow hadn't washed since her dip in the lake. Because she hadn't used soap on that occasion, she smelled worse than Applejack had three days ago.

They were just feeding a pig when a wisp of smoke suddenly flew by them and engulfed the pig. The pig grew to four times its size, with a bigger nose, and drooling a lot more.

"Uh-oh," said Applejack. "Looks like another one of them anomalies from Equestria happened here."

The pig sniffed, and turned toward Rainbow Dash and Applejack. It sniffed in their direction a bit, then jumped out of its pen and ran directly at them.

Rainbow and Applejack ran, but the pig was faster. It pinned Rainbow to the ground facedown. It lifted her skirt in its flat teeth, exposing the butt of her stinky shorts. After sniffing deeply for a few seconds, it began to lick her butt, coating it in its gooey saliva.

"Hey!" said Rainbow Dash. "Stop slobbering on my butt!"

The pig continued to lick vigorously. Rainbow Dash let out an explosive wet fart. The pig sniffed, and then engulfed her rear in its mouth and started to suck on it as if it were a lollipop.

Applejack laughed. "I think it likes the way you smell, Rainbow."

"Don't just stand there!" said Rainbow, who was red in the face. "Call Sunset Shimmer!"

"She'll already be on her way," said Applejack. "She said her magic stone picks up stuff like this."

The pig stopped to catch its breath, drooling profusely. The drool plopped onto the smelly girl's rear. She tried to crawl forward, but the pig started licking her dirty rump again, as if trying to lick all the sweat and grime off it.

Then, it stopped. Rainbow turned around and saw the pig had been restored to its original size, looking confused.

"Thanks Sunset," said Rainbow. However, when she stood up and turned to the side, she saw a purple girl with dark purple hair that was in a ponytail and had pink streaks. She wore glasses, a blue T-shirt, and short purple shorts, and held some sort of scientific device in her hand.

"Oh, you must have me confused with someone else."

Then Sunset arrived, looking puzzled. "That's funny... my magic stone said the anomaly was right here." She saw the new girl. "Twilight Sparkle?"

"How did you know my name?" said the girl.

"Oh... never mind. Where I'm from there's someone who looks just like you."

"One of my pigs turned into a monster and... attacked Rainbow Dash," said Applejack.

"Is she all right?"

"All it seemed to be doing was licking her butt before I turned it back to normal," said Twilight.

"Twilight!" Rainbow blushed, instinctively putting her hand on her butt, which was still drenched in pig slobber.

"How did you do that?" Sunset asked Twilight.

"This may be hard to believe, but there is another world out there," said Twilight. "A world of magic and talking ponies."

"We already know about Equestria. I'm from that world."

"Oh. Anyway, I've been monitoring all the anomalies, and I discovered there's a breach between worlds. Not like the portal you probably came here through, but there's one that magic is coming through-"

"Yeah, I've been following that, too, and I've been using a magic stone to fix them."

"So that's why they dropped off the radar after a while. But, in case they started to stay longer, I made this handheld machine that will fix any anomalies!" She held up the device. "Ta-da!"

"Wow, you're quite the scientist," said Applejack.

"Thanks. I spend all my time studying, so I don't really have any friends. But, it's been really fun talking to you. Will you be my friends?"

"So, if you know about the portal, and the ponies, have you been to Equestria?" said Sunset.

"Of course. I wanted to study that new world. I turned into a unicorn there."

"Well... you probably also know..."

"How flatulent the ponies can be? Yeah."

"Well... you should probably know that doesn't change for me when I'm human. Nor does the smell get any better. I hope you don't think I'm disgusting or gross. My friend Rarity has air freshener, so-"

"If anything you should think the same thing about me."

"Why?"

"This is a little embarrassing to admit, but... I love reading and studying so much, that I don't stop for bathroom breaks. Unless it's number two, of course. That'd be way to messy to clean up."

"So..."

"So, I pee in my shorts whenever I get too desperate to concentrate." She blushed.

"If you're not disgusted by my farting or Rainbow Dash's smell, then I won't be disgusted at you for that. Besides, you wouldn't be my first friend who uses her shorts as a toilet a lot."

Twilight hugged Sunset. "What do you mean, Rainbow Dash's smell?"

"I don't wash very often," said Rainbow.

Twilight sniffed her, then held her nose and backed away a bit, fanning the air. "Ugh, you do smell awful. But, I suppose it's not as bad if I'm not too close to you. If I licked your butt, I'd throw up. I mean... not that I'd ever lick your butt, of course..." She blushed again. "But don't worry. I'll still be your friend, if you want."

"Sure."
