Floatzel and Snivy decided that enough was enough - they were going to beat Mienshao at her own game or die trying!  Those were more Floatzel's words than Snivy's, but either way, they were partners!  They couldn't leave one another to fight the big bully by themselves, so they made a pact.  

"Eat the smelliest berries you can, and as many as you can!"
"Floats; I dunno about this..."

The two walked along a dark forest path with hundreds of different breeds of berry trees strewn about.  Floatzel had a taste for some of the rarest types of berries, but Snivy was a bit more reserved; preferring more all-around tasty ones.  Floatzel was dead set on trumping Mienshao, though; and as such had her heart set on a Starf berry bush she'd gotten a clue about in town.  It was deep within the forest; off the beaten path about four hundred yards away, and rumored to be protected by a male Ursaring who had a taste for the same!  Floatzel's tummy grumbled as she hadn't eaten all day, but Snivy was fine for the moment - she just had snacking urges right now!  Snivy grabbed a bunch of green Lum berries and chewed on them, cracking open the hard shells to get at the softer, bittersweet center on the way.  Snivy followed quietly behind, but Floatzel stepped on a branch and made her spill the remaining few berries she'd collected all over the ground!

"Shh!  I don't think we're alone here, Floatzel--"
"Oh, be quiet Snivs!  It's just a twig."

Floatzel pointed over to a green, blooming tree-bush that stood at just about her height.  In said trees lay the berries she'd had her heart set on for so long - Starf berries!  Ooey-gooey rainbow-star-tipped white curls of deliciousness awaited them both as Floatzel navigated the underbrush, knocking other types of berries off some bushes along the way.  Snivy took to hopping up on her shoulders as she got stuck trying to dig around the much larger brush, snapping a couple more twigs underfoot while Floatzel trekked along.  Floatzel finally got within striking distance of the bush, and she reached up to pick one such berry off of it!  The bush only had one berry left on it, though.  Floatzel wanted to eat it, but she gave it to Snivy instead.

"Here Snivs, give this a try!  It's oh-so-good~"
"But it's the last one!"
"There's more nearby; I'm sure of it!"

Snivy cautiously bit into the swirlingly sweet berry and blushed heavily as it caused her to forget herself for a second!  She let loose with a foul-stenched fart on Floatzel's back, making the orange girl gasp and chuckle a little bit to herself!  Snivy immediately covered her nose and pinched at it, as even her own farts triggered her mega-sensitive nostrils to recoil in disgust!  She fanned at her rump and finished off the rest of the berry, shuddering as the mixture of flavors in her mouth converted her over to Floatzel's side of the taste arena!

Floatzel walked around the bush, finding a smorgasbord of the same berries growing in a little set-aside grove from the rest of the forest, immediately walking towards the fresh produce and picking a couple off the branches of the tiny tree.  She devoured them in big bites, letting the cacophony of flavors wash her tongue in a fantastic swirl of flavor!  Snivy ate another one, but recoiled when the bush pushed back against her paw!  She yelped and dashed behind Floatzel as the orange one never took notice of the big, furry rump pushing through the bushes.  An Ursaring thrice Floatzel's height leaned against the much smaller bushes, spreading his cheeks while he reached up to grab at some tangy Sitrus berries in a tree that the two females wouldn't have a chance in hell of reaching.  Snivy held her nose pre-emptively as the Ursaring let out a beefy, wet fart that sent Floatzel's sinuses into a tizzy; breathing in the stench of the bear's ass made her cough and give away her position.  Snivy did well to anticipate a fart, but her eyes were still open, and Floatzel couldn't hold her bowels in proper with all that diaphragm action going on!  She farted right into Snivy's eyes, making them water and causing the poor girl to have to make a decision - wipe the gas out of her eyes, or keep her nose plugged!  The Ursaring took notice of Floatzel's coughing; turning around intimidatingly and growling ferociously at the two females on the ground.

"What are you two doing?  Those are MY berries, damnit!"
"*cough cough* Your berries?"
"Yeah.  MY BERRIES."

The Ursaring growled and leaned down towards Floatzel and Snivy, baring his teeth and looking rather intimidating being so tall, buff and strong!  Snivy immediately hid behind Floatzel, per the norm, but the orange one stood up to the big mean bear instead!

"The forest is full of berries; why are these yours specifically?"
"Because I planted them MYSELF.  What berries have you two little thieves planted recently?"

Floatzel erhmed to herself as she thought and scratched the back of her head.

"None recently... why?"
"You don't reap what you don't sow.  And those were the last reapings I had of those berries... so here's what's going to happen.  You two are going to stay here for a while."
"B-but we were just looking for a snack before dinner--!"

Snivy poked her head out but immediately ducked back behind Floatzel as the Ursaring gave her a glare, too.

"You two are going to stay here.  Until those seeds come back out of you, you're not going anywhere."

Floatzel huffed and brushed up her arms, looking to pick a fight instead!  She had things to do beyond being kept beyond her will!

"How about instead of that, we leave and never come back?  I don't think you want to mess with the two of us."

The Ursaring laughed up into the air, smacking his large gut and almost tumbling over!  Snivy gave Floatzel a quizzical look while he did so.

"YOU TWO?  Beat ME?  That's hilarious enough that I'm gonna take on your challenge.  No attacks, either!  I think my gas will work good enough; I've just finished stuffing my face for the afternoon anyway!"

The Ursaring wasted no time and gave the other two no chance to react as he turned around and quickly pushed out his tush against the bushes again.  Floatzel scampered away out of the fart's reach in time, but little Snivy caught most of it doing the same.  She ran out into a clearing of soft earth and some grass, coughing with tears floating from her eyes.  The Ursaring gave chase and tore down his precious bushes, knocking the empty-seeded plants to the ground as he bounded along; full of rage, gas and a penchant for showing smaller creatures their place in his forest!  Snivy coughed loudly as the Ursaring zoomed over her like a truck straddling a cowering squirrel on the freeway, ruffling her skin and making her wince for a short bit.  Floatzel dodged the huge tank as he leapt upward, landing where she was.  The Ursaring sank a little bit into the soft dirt as he opened his bunghole, spraying the ground and knocking dirt powerfully out of the way with a fifteen-second blast of ass gas!

"Hey, dummy!  You missed me!"

The Ursaring made a face while he pooted, showing signs of relief as the assortment of gas producing berries made his gut lessen, but pop right back up to its previous bloated size once he was done.  Floatzel teased the big lummox while he gassed the ground, making his gaze once again look ferocious as he bounded along towards Floatzel again.  Snivy hadn't recovered full yet; still crouched down in her stance on the floor of the forest.  The Ursaring bounded towards Floatzel who didn't know Snivy was right behind her.  She knew that she'd either have to wear him down in order to win this fight, so she dodged once again, but didn't notice until it was too late that Snivy was going to get a faceful of ass!

"SNIVS; LOOK OUT!"

Snivy looked up with quickly dilating eyes at the large Ursaring putting on the brakes in reverse!  Soft earth flicked from either side of his heels as his butt reared up and slammed backwards on Snivy's face!  For a short moment, everything in Snivy's mind went in slow motion; the musky smell of bear buttcheeks spreading over her mouth and the hole belching gassy air over top of her skull made her immediately snap back into reality.  She flailed as best she could with her much tinier frame while the Ursaring pushed on his gut, sending more and more gas downwards into the buried green Pokémon below.  Floatzel gasped loudly, then rushed over to the Ursaring's side, leaping up onto his back and scampering over the coarse fur thereof.  The Ursaring tried to knock Floatzel off by moving his body from side to side, but that was exactly the kind of movement Floatzel was used to in the water!  She reached his head and vaulted backwards until all the bear could see was water weasel snatch and a part of her feet!

"Big bully!  Get off my friend!!"

Floatzel immediately grabbed onto the bear's head and made his nose turn fifty shades of disgusted as she let loose with a particularly wet fart in a lingering cloud!  The Ursaring immediately held his nose and flopped over to one side, writhing in disgust as the fetid cloud seemed to linger in his nostrils!  Floatzel hopped off of his head before he made a loud *THUD* against the soft earth below.  Snivy was almost flattened by the Ursaring's weight on her, coughing a couple times and making a rather over-dramatic show of the ordeal.

"Floaty... go on without me... *hack*"

The orange water weasel grabbed the green garter snake's paw and lifted her up out of the comically bear-shaped buttcheek prints on the ground around her.  Snivy coughed a few times while she looked over to the Ursaring gnashing his teeth in the dirt.

"Jeez... Floats, what'd you do?"
"I gave him the ol' one-two gassin'; is what I did!"

Floatzel gloated about her victory for a bit too long as the Ursaring started recovering, leaning up with a malicious angry fire in his eyes.  He'd worked up a sweat from bounding about for so long, and those berries in his gut weren't helping matters while they digested and kept giving him plenty of gas to work with!  He bounded at the two again, forcing both a flash of green and orange to avoid the brown freight train charging at them both!  He took a gassy tumble as he squeezed a long series of beany farts out of his tush, rolling to a halt in a heap a few yards away.  Floatzel and Snivy both gasped for air as they waddled out into the center of the clearing, trying to find their way back into town.  By now there had been so much gas exchanged that there was a tinted miasmatic cloud hovering about the clearing, making some weaker plants wilt and berries fall to the soft ground below them.  The Ursaring huffed and puffed as he stomped over to the quickly-winded Floatzel and Snivy, reaching down and pinning them both with gigantic claws caging them in.

"You two are more trouble than you're worth!  It's time I showed you why they call me the 'Boss Poké' of the forest..."

He released his grip on the two as they weakly started to stand up again.  Floatzel coughed and Snivy gagged while they huddled together, unable to see through the waning light as the miasma grew thicker.  The Ursaring hopped up into the air over top of Floatzel and Snivy, and all hell broke out from that evolved ass of his!  The Ursaring held himself in mid-air as he passed enough gas to make Snivy cry from the stench filtering through her nostrils!  Floatzel couldn't take it as the Ursaring billowed wetly overhead; his cheeks flapping everywhichway under the intense power of his gassy butt!  He held that fart for five minutes straight; leaving his gut much less bloated by the end of it all.  A thick, greenish-yellow cloud hovered over the clearing, leaving Floatzel and Snivy passed out from the lack of oxygen in the bear's farts.  He stood over top of them, squatting nice and close for one last body-rolling poot of victory before he reached down, grabbing orange and green and tossing the two girls over his shoulders.
Some time passed before Floatzel woke up; having faded out of consciousness for at least until the moon and stars had come out!  Snivy had passed out completely and was still out, but Floatzel managed to wake her up along with a retch or two from the green one's throat.  Snivy spit on the ground while Floatzel helped her up to her feet.  The place they were in was dark, wet, and foul smelling.  The Ursaring from earlier had his feet propped upside down on one side of his cave set deep into the side of a mountain's face nearby where he'd defeated the two girls at.  Floatzel stood up woozily and coughed a couple times while Snivy waddled about as if she were confused!

"Okay... you win... can we go now?"
"Not until you fill in those holes out there.  I'll be watching you, weasel."
"How am I gonna do that?  I'm no gardener..."
"You'll figure it out.  Otherwise we can keep going back and forth with you waking up dazed and confused until you do."

Floatzel bit her lip while the large Ursaring toyed with some strange two-screened device she'd never seen before.  She peeked outside into the clearing where they'd just come from from the cave's entrance, and the Ursaring let her out while Snivy followed closely behind.  Floatzel had to go to the bathroom again by now, as did Snivy.  The two of them waddled back and forth, peering at the empty, farmable ground for a few minutes, unsure as to how to fulfill their order from the Ursaring.  Floatzel caught on before Snivy did, however; but those holes would need to be a bit deeper if she was gonna pull it off.  The Ursaring watched the orange and green one work through the night as Floatzel positioned herself over each individual hole, bending forwards while Snivy took a little stick to dig down deep enough for Floatzel to do her business in.  Floatzel pushed out a glittering log into the first hole with a quiet *plap* of soil meeting soil, and Snivy caught it, breaking it up into chunks that would fit in the little holes in the ground.  Floatzel turned back to the curious Ursaring; his face lit up with a curious grin on his face while Snivy planted the seeds buried in her shit.

"You could've just told us you wanted us to do this, you know..."

The Ursaring chuckled and took on a mocking tone while Floatzel pushed out another turd into Snivy's paws; the little green one bucking up and tanking the smell like a true trooper (yet again)!

"You could'a just heard me out instead of trying to fight me, you know...~"

Floatzel took thirty minutes with Snivy to replant the seeds into the dirt - they'd have plenty of fertilizer to work with!  She filled almost forty holes with her fecal matter, and Snivy needed to brush her paws off well and good by the end of it. She farted backwards Snivy, who she thought was still behind her; but the little green one was filling a much larger hole with a good bit of shit herself!  She held her tummy, squeezing out a coily turd pile, then covering it up with crap.  Floatzel had finished up her dump as well, so the two of them decided that it was time to head back into town for a well-deserved shower (or in Snivy's case, a full-on bath)!
