Here's a commission bought by my best friend https://twitter.com/Crabb3dL3af /  CrabbedLeaf of his ADORABLE Smeargle OC Rustle having some growing fun with his uncle Kajex!

This was honestly a ton of fun to work on! It was something I'm very comfortable wrting and had characters I love in it! And I honestly recommend you all follow Crabbo on Twitter. He's honestly a HUGE dork!

---

It was a typical, sunny day in Crab’s laboratory. Crab (dorkiest scientist Lucario of all) was currently about to have a meeting with a client for a new invention of his. He’s currently asking Kajex for a quick favor before he becomes super occupied with work.

“Listen here dork,” Crab began as Kajex let out a yawn, “I need you to go downstairs and check up on the Berries real quick.” “Okaaaay doofus,” Kajex rolled his eyes at, “I’ll take care of it right now in fact.” “Thaaaank you best boy,” Crab smiled as he ruffled Kajex’s head fur, “Just write down anything unusual on some paper and set it in my lab.”

Crab gives Kajex a special key from his coat pocket with a dorky smile.

“Just DON’T take the light growth potion again!” Crab ascertained to him, “I do NOT want a repeat of last time!” “I promise I won’t ya doof,” Kajex replied, “If I do you can… boop me to oblivion.” “I was gonna do that anyways,” Crab snickered, “But I’ll trust you.”

Crab then left Kajex with another good ruffle of his head fur before he left the room, Kajex awkwardly standing there for a moment.

“I’ll just steal a Yellow Berry and mix it with your coffee in the morning,” he snickered to himself, “THAT’LL be a treat!”

Kajex then began to head over to the door leading downstairs, but he had a little… guest following him, a little Smeargle by the name of Rustle.

“Hehe, I-I can’t wait to give u-uncle a good scare,” the small Smeargle snickered to himself as he weaved around corners like a spy in a movie, “H-His face is gonna look so p-priceless!”

Kajex then inserts the key into a slot in the wall before a door opens in front of him, cautiously going down the steps as Rustle gets slightly caught off guard by the door.

“Wh-Whoa,” Rustle stuttered in awe as he watched the door open, “Th-That’s so coooool! Never s-seen that door!”

Rustle then slinked over to the inside of the door where it was suddenly closed and locked behind him.

“I-I guess there’s no turning back,” he mumbled to himself, “U-Uncle can let me out.”

Rustle then stumbled his way down the steps, the sounds of Kajex’s casual whistles echoing ahead of him seemingly alluring him to delve deeper.

“Th-This is so awesome!” Rustle remarked to himself again as he neared the bottom of the stairs, “Wh-What’s down here?”

Rustle soon then arrived in a dimly lit room at the bottom of the stairs, the entire room filled with bushes of Berries of all different colors, with Kajex currently examining the white Berries.

“S-So this is the Berry Farm they were t-talking about!” Rustle whispered as he examined Kajex, “Cooool!”

Rustle quickly hid behind the Red Berry bushes as Kajex nearly caught him for a brief moment, thinking he heard something squeak before getting back to work.

“Looks like the White Berries are fine, no issues here,” Kajex mumbled to himself, “Now what about the Purple Berries?”

Kajex moved over to the Purple Berry bushes as Rustle peeked out from behind the bush, his urges to spook unparalleled.

“Hehe, u-uncle won’t know what hit him!” Rustle softly snickered to himself as he slowly crawled out from behind the bush, “Th-This is gonna be-”

He however stopped himself instantly as his stomach let out a soft grumble, signifying he was hungry.

“O-Oh no,” Rustle groaned to himself, “I’m so huuuuungry! I-I didn’t have snack time today!”

Kajex let out a hefty sigh as he started scribbling stuff down on a slip of paper.

“The Purple Berries are starting to wilt a bit,” he remarked to himself, “Gonna have to examine the soil later. Definitely not a good sign for these ones.”

Kajex moved over to the Green Berries as Rustle’s stomach growled more as he looked at the Red Berries in front of him.

“N-Nothing bad is gonna happen, r-right?” Rustle thought to himself as he plucked a Berry, “I-It’s just fruit…”

Rustle ate the Berry in a single bite, the juices oozing all over the inside his mouth as he swallowed it, enjoying the taste heavily.

“Mmmmm,” he muttered as he licked his lips and rubbed his belly, “Still h-hungry though.”

He ate more and more Berries, not noticing how each berry he ate made eating the next one even easier, how his head poked out from above the bush now. He was growing and he didn’t even realize it.

“At least the Green Berries are fine,” Kajex remarked to himself, “Now let’s check out the coffee destroying Yellow Berries for tomorrow and then the-”

Kajex awkwardly turned around to see Rustle already more doubled in size, awkwardly falling into the green bush like a plank of wood as Rustle let out a cute burp when the entire Red Berry bush was picked dry.

“Ah, that hit the spot,” Rustle smiled as he patted his belly again and stood up, noticing Kajex in the bush, “O-Oh hiya uncle!”

Rustle walked over and loomed over the comparably short Lucario with a cheery smile on his face that made the Lucario blush.

“Y-You okay?” he asked as he tried to get the shocked look off his face, “You look like you saw a ghost.” “D-Did you eat ALL the Red Berries?” Kajex stuttered, “B-Because that’d be VERY bad!”

Kajex sits up awkwardly and looks at Rustle, the pup now noticing the height difference between the two now.

“Wh-What did those berries do?!” Rustle stuttered as he started to panic slightly, “Wh-Why am I so tall uncle?!” “Red Berries cause growth spurts!” Kajex replied as he got onto his feet, “But… you should be WAY taller if you ate the whole bush!”

Kajex quickly decides to write down that little detail real quick on his paper, noting it as a quick test.

“S-Sorry uncle,” Rustle blushed as he looked down at him, “I-I wanted to give you a scare a-and then I got hungry, a-and-” “Oh you're fine Rustle!” Kajex assured him as he gave Rustle head pats and hugs, “But you should know that you shouldn’t eat ANYTHING Crab makes!”

Rustle couldn’t help but to hug the Lucario like a teddy bear in response.

“I-I swear I won’t do it a-again!” Rustle exclaimed, “P-Promise!” “Glad to hear it,” Kajex wheezed, “Can I finish my work before I give you the cure? J-Just got two or three bushes left.” “O-Oh sure!” Rustle smiled as he let go, I’ll wait right here”

After Kajex took a second to catch his breath, he got back to checking on the Yellow Berries next, Rustle’s tail swaying side to side happily as he sat on the floor.

“Yellow Berries…” Kajex began, “The Berries look fine, but the bush looks a bit old. He might need to plant a new one soon.”

He writes down another note on the paper as he moves onto the Black Berries, but Rustle’s stomach began to ache heavily as he clenched his gut.

“U-Uncle,” Rustle groaned as it ached more, “My tummy hurts really badly!”

Kajex jumped a little as he heard Rustle’s stomach groan and ache, Rustle wincing a little at discomfort.

“I-I’ll get you some White Berries stat!” Kajex stated as he dropped everything he was doing and darted to the White Berry bush to pluck a few, but Rustle's tummy only grew more painful.

“A-Almost ready!” Kajex stammered, “Just a bit long-”

Just as Kajex turned around to give Rustle his berries, Rustle had a HUGE growth spurt that squished the berries against Kajex’s coat with a paw, Rustle taking up the whole room as his spurt squished all the berries into nothing.

“Wh-Whoops,” Rustle chuckled awkwardly, “G-Guess at least my tummy doesn’t hurt anymore?”

Kajex squirmed as his head popped out from atop Rustle’s plush paw, Rustle’s face now extra red as he looked back.

“Wh-Whoa!” Kajex stuttered, “The Berries are behaving oddly!” “I-Is this bad uncle?” Rustle blushed as he tried to pull Kajex out. “I-It probably is Rustle,” Kajex awkwardly replied, “B-But it looks like it was one burst!”

Rustle couldn’t get kajex out from under his paw, but his stomach began aching again, already making Rustle wince in discomfort.

“I-I don’t think it was a one and done deal uncle,” Rustle winced. “A-And all the White Berries are gone,” Kajex replied, “U-Uh oh…”

Rustle clenched his belly for a brief moment before another groan made him SURGE with growth again, his head smashing into the lab and beyond as he outgrew the lab itself Kajex now DEFINITELY trapped under pup paw.

“O-Owww…” Rustle groaned as he rubbed the back of his head, covered in debris, “Th-That didn’t feel good uncle… uncle?!”

Rustle panicked a little as he managed to lift his foot to find Kajx half brain dead in a chunk of debris.

“I’m going to the moooon,” Kajex said in a dazed tone. “I-I’m so sorry uncle!” Rustle replied in a panic.

Rustle then SQUEEZED the tiny Lucario in a hug, snapping him back to reality as Rustle stood up.

“R-Rustle?!” Kajex wheezed, “Y-You’re fine Rustle” “I-I didn’t mean to hurt you uncle!” Rustle stuttered as he squeezed him even tighter, “I-I’ll put you somewhere safe!”

Rustle then plopped Kajex on the tip of his nose, where Kajex began to cough and wheeze quite a bit from the giant pup’s hugs.

“D-Definitely safer than under your paw,” Kajex wheezed. “And you look a-adorable on my nose uncle!” Rustle smiled.

Rustle glanced all around his surrounding, treetops now barely able to graze his ankles as he began to walk around a little.

“U-Uncle?” Rustle blushed, “D-Do these Berries wear off naturally or…?” “Th-They don’t Rustle,” Kajex awkwardly replied, “Y-You’re stuck like this.” “O-Oh boy,” Rustle blushed as his tummy growled, “B-Bad time to be hungry.”

Rustle couldn’t help but to rip a few trees out of the ground and eat them because he was so hungry! Kajex’s worry began to skyrocket as the land was torn apart.

“Mmmm, tasty,” Rustle said as he munched on the treetops like cotton candy, “Not very filling though.” “H-Hehe, I guess so,” Kajex chuckled as he clung to Rustle’s nose, “But PLEASE don’t think about eating me!” “I-I promise I won’t!” Rustle stuttered after he finished his first tree, “But you do look like a tasty snack!”

Kajex let out a soft squeak and clung to Rustle’s fur tighter, Rustle devouring a tree trunk before nomming on his next tree.

“O-Only kidding!” Rustle stammered as he kept munching on a tree, “P-Promise.” “I-I believe you” Kajex stuttered as he loosened his grip, “... mostly.”

Rustle kept up an awkward blush as he continued to devour tree after tree, his belly slowly filling up, but still growling.

“Th-These trees will have to do,” Rustle grumbled as wood chunks poked his tongue, “But it hurts a lot to chew.”

Rustle swallowed another tree, his belly beginning to groan again as a city came into view.

“You gonna be okay?” Kajex asked, quite concerned, “You might’ve eaten TOO much!” “I-I’ll be fine uncle,” Rustle awkwardly chuckled as he came to the city.

But all that happened was that the groans grew more ravenous, craving for something to fill the void inside his stomach.

“My tummy still feels so empty uncle!” Rustle groaned. “W-Well, there aren’t a whole lot of things you can eat currently” Kajex awkwardly replied, “I wonder why you can’t seem to feel fu-”

Rustle soon arrived in the city, his paws leaving imprints in the asphalt as his swaying tail crashed into window after window, but he started to feel uncomfortable again.

“S-Sorry little city,” Rustle winced as his belly groaned, “I-I don’t feel so-”

In that instance, his stomach let out an explosive groan as he had another MASSIVE growth spurt! Several buildings now just below his waist.

“Wh-Whoa…” Rustle stuttered as his paws now took up the whole road, “Th-This is kinda cool!”

Kajex was now almost completely surrounded by bushes of fluff as Rustle awkwardly tiptoed his way out of the city, slightly bouncing with each step Rustle made.

“Th-The berries are STILL active?!” Kajex stammered, “O-Oh boy...”

Rustle caused wave after wave of destruction as he stepped to the exit, footprints completely massacring the road, or his sides knocking down a building. He was EXTREMELY embarrassed at each and every turn.

“Th-This is kinda scary…” Rustle stuttered, not knowing how loud he was now, “B-But it’s also pretty cool!”

Rustle began to let out soft chuckles as he looked down at Kajex, now almost out of the city.

“I bet it is Rustle!” Kajex replied as he peeked over his nose, watching vehicles and flower stands get accidentally flattened into pancakes, “A-Although you might wanna stay out of cities next time.” “I-I’ll try to!” Rustle stuttered.

Rustle’s tail however, accidentally wrecked another two or three buildings with a happy tail wag as he left the city, awkwardly turning around to see the accidental wave of destruction he left behind.

“U-Um… whoops?” Rustle awkwardly blushed as he rubbed his head. “A-A very big whoops,” Kajex continued.

Rustle then continued their little stroll, trees now more like freshly cut blades of grass now, but was still very hungry and his belly was still hurting.

“A-And I think it’ll be a bigger whoops in a minute uncle!” Rustle groaned as he clenched his stomach. “How many berries were on that bush?!” Kajex stuttered as Rustle left a paw print crater in a large hill, “There’s NO way you could’ve eaten THAT many!” “U-Um… a couple dozen,” Rustle awkwardly replied, “I-I believe…”

Kajex’s heart sank once he heard those words, Rustle wincing in discomfort more.

“H-How’d you even eat that many?!” Kajex stammered, “You're smo… well normally!” “N-No breakfast?” Rustle stuttered, “A-And skipping snacktime?”

With that sentence uttered, Rustle had another surge that was a MASSIVE one compared to the others! The average mountain was now just above his knees, the land below now having meteor sized, paw shaped craters instead of hills.

“Wh-Whoa!” Rustle stammered as he tried to get his balance back from the surge. “B-Be careful!” Kajex stammered, “You’re gonna-”

Rustle fell onto his stomach after he lost all sense of balance, the entire earth around him cracking and quaking as miles of life were blown away and the city they attempted to save completely flattened under puppy tummy.

“... fall.” Kajex finished as flopped onto his stomach. “V-Very sorry about that,” Rustle blushed, “But this is AMAZING!!!”

Rustle happily got back on his feet, the remains of the city falling from his fur like bread crumbs before he started a casual, yet destructive walk to another city.

“Th-These tummy aches are worth it!” Rustle smiled as his attention was taken by a mountain range in the distance, “I-I wanna keep this up!” “W-Wait actually?” Kajex squeaked as he heard each footstep make an explosive sound.

The whole trip consisted of Rustle’s playful giggles as his head tore the clouds apart and the ground tore to shreds, stopping at the mountains.

“Mountains are nothing to me now!” Rustle exclaimed confidently as he stepped over the mountain like it was just like a short fence. “Th-They definitely aren’t,” Kajex blushed.

Rustle happily skipped over the mountains, but his tail swayed and knocked off HUGE chunks of the mountaintops, seemingly doing nothing while his belly began to ache again.

“Well, if you were a bit taller yeah,” Kajex awkwardly joked, “Then they’d be-”

They awkwardly look down at the base of the mountain, where a landslide caused an entire city to get completely destroyed in its wake.

“U-Uh…” they both awkwardly began in perfect unison, “Whoops?”

Rustle awkwardly slinked away from the city as he held his belly, but his tail wagging so fast you could almost think a tornado was coming after you on the ground below.

“I’ve never been so happy to feel a tummy ache in my life!” Rustle winced in discomfort once again. “A sentence I never thought I’d hear in my life,” Kajex awkwardly replied. “O-Or anything I’d say,” Rustle groaned as he clenched his stomach tightly.

And with another groan that was almost as loud as a nuke going off, Rustle had another TITANIC surge in growth, his toes now almost as tall as the mountains he just had to step over and the stars not too far out of his reach.

“I-I was ready that time!” Rustle stammered as he got his balance. “Th-Thankfully you did!” Kajex replied as he was now barely able to wrap his arms around a strand of fur.

From Kajex’s perspective, he was in a foreign land. He was surrounded by strands of fur the size of large trees and was starting to lose access to light amidst all the fluff overhead.

“I-I didn’t wanna go flying a hundred miles away!” Kajex stammered. “I-I don’t wanna lose you either uncle!” Rustle replied, “But uh… wh-where’d you go?’

Rustle was now so gargantuan he couldn’t see his precious uncle hiding in the sea of fluff, but the sounds of his voice signifies that he’s still thankfully on his nose.

“I-I can assure you that I’m still right where you left me,” Kajex blushed. “Oh wow uncle!” Rustle smiled, “You’re so TINY!! I can’t even see you anymore!”

Rustle then happily began walking again, causing earthquakes with each step he took as Kajex kept bouncing a few dozen feet in the air between each step.

“Y-Yeah I’m probably not even a bug compared to you Rustle!” Kajex stammered. “Y-You must be so a-adorable and blushy down there uncle!” Rustle smiled again, “Wish I-I could see it!”

All that did was make Kajex flare up even BRIGHTER, a plane now flying by Rustle’s stomach like it was a mere fly buzzing by.

“Goodbye tiny plane!” Rustle chuckled, “See you later!” “Even when he’s dwarfing mountains he’s still my precious painter pup,” Kajex thought as the earth below was ripped to shreds.

Rustle whistled away as he strolled along, mountains becoming craters, lakes looking more like giant puddles, forests becoming deserts already, but he kept the same, happy expression on his face.

“I-I wonder how big the next one’s gonna be!” Rustle thought aloud, “I-I wonder if I'll make continents l-look like rugs!”

Kajex tried to climb a fur strand like a tree, but he would only slide back down it like a fireman’s pole and get sent flying into the air again.

“Y-You’re already almost big enough to make the whole planet your bedroom!” Kajex stuttered as he bounced again. “Y-Yeah!” Rustle smiled, “J-Just a really big bedroom!”

Rustler's stomach let out a growl the whole planet could hear like an atomic bomb went off.

“D-Doesn’t do anything f-for my tummy though uncle,” Rustle groaned, “I-I’m still STARVING!!!” “Y-Yeah that’s true,” Kajex stuttered.

Rustle playfully licked his lips.

“D-Don’t do it Rustle!” Kajex stammered, “I-I’ll bap your snoot!” “I-I was only kidding u-uncle,” Rustle whimpered, “S-Sorry.”

Rustle was giving Kajex the sad puppy eyes that made him feel instantly bad about his reaction to the obvious joke.

“I-I’m sorry Rustle,” Kajex replied, “I-I just get a little… off when people joke like that.” “O-Okay uncle,” Rustle replied with a tail swish, “I-I’ll keep that in mi-”

Rustle was so fixated on Kajex that he wasn’t watching where he was going, feeling a multitude of seemingly metal pieces bend against his paw.

“U-Um.. what was that?” they awkwardly asked in unison.

Rustle lifted his paw as slowly and awkwardly as possible to see he left a paw print in the DEAD center of an unfortunate city below him, the ring of buildings around it completely leveled from the aftershock.

“O-Oh…” rustle awkwardly as as his stomach groaned again, stepping to the side of the city, “S-Sorry I-I was having a ch-chat with my uncle!”

Result however blew away the rest of the city with a single step with the shockwave, letting out a soft, “eep.” as he tried to walk away before the next spurt.

“The next one is on the way… isn’t it?” Kajex awkwardly asked him. “M-Mhm,” Rustle nodded as he held his stomach, “A-Any second in fa-”

Rustle’s stomach groaned and made the skies themselves tear apart, the pain so immense he had to use his tail to help squeeze his belly.

“O-Ow!” Rustle winced as his grip tightened, “Th-This one hurts a-a lot!” “U-Uh oh…” Kajex squeaked, “I-It’s gonna be the biggest one yet.”

And then within seconds, Rustle grew even BIGGER than before, the upper reaches of the atmosphere at his stomach now, his tail swishing sending entire mountains flying now.

“COOOOOL!!!” Rustle exclaimed in pure awe, “L-Look at me now u-uncle! I-I make continents look l-like stepping stones!” “Th-That’s great to hear Rustle!” Kajex stuttered, now absolutely unable to even see Rustle’s face.

Kajex however felt IMMENSELY nervous at the display. Just the mere motion of Rustle lifting his paw was the equivalent to an earthquake to him, not even able to stand anymore.

“Th-Those berries REALLY kicked into overdrive!” Kajex stuttered as he went FLYING into the air after a single step. “I-I’m gonna go on a w-world tour uncle!” Rustle smiled as he glanced at the earth below, “H-Hang on!”

Rustle then began to playfully skip all around the world, each one making the earth beneath him split apart and left country sized paw prints in his wake, easily wiping away hundreds of miles of earth below.

“And another one goes smush!” Rustle giggled as he skipped over an ocean, “This is so much fun uncle! Most fun EVER!!!” “G-Glad you think so Rustle!” Kajex exclaimed as he became eye level with Rustle for a moment, “Y-You look extra adorable too!”

Rustle’s smile only began to glow brighter with those words, his tail wagging faster as he skipped across the planet like a child hopping across rocks to cross a river. Rustle was still as innocent as always.

“If there was only something to eat I’d be th-the happiest pup alive!” Rustle said as his tummy growled again. “I-I guess that is the one thing that could be fixed,” Kajex said as he crashed into Rustle’s fluff.

Rustle kept happily skipping away, more than likely flattening hundreds of cities, but was having too much fan to care. However, he glanced at the ocean as his paw slammed into the middle of it.

“I-I wish the ocean wasn’t so salty,” Rustle remarked to himself, “I-It’d make a great drink, but it tastes so nasty!” “A-And awful for your health,” Kajex replied.

However, it seems that Rustle’s stomach was listening to him, groaning and rumbling once again, his hunger almost insatiable.

“O-Oh boy uncle,” Rustle groaned, “I-I think this is gonna be the last one!” “Wh-What makes you say that?!” Kajex panicked as he felt the tremors all the way up on Rustle’s nose. “I-I just have a, ‘gut,’ feeling, hehe,” Rustle winced.

Kajex couldn’t help but to snicker at the pun.

“Hehe, I taught you well in the art of puns,” he snickered, “If you can make one like that while you’re in pai-”

Then it happened. With a cataclysmic stomach groan Rustle grew even bigger and bigger! Hopping off the planet mid spurt he was growing that huge and beyond! Kajex only being held against Rustle by his sheer force of gravity. This went on for quite some time until the planet was small enough to slip into his mouth with ease.

“THE PLANET LOOKS SO TINY UNCLE!!!” Rustle exclaimed with glee, “IT’S SO CUTE!!!” “N-Not as cute as you though Rustle!” Kajex stuttered.

Rustle giggled so loudly, he could’ve been heard for lightyears, but that giggle was soon over powered by hunger as he looked at the planet and it’s extra tiny moon.

“I-I can’t handle the hunger anymore uncle!” Rustle whined as he ripped the moon out of orbit, “I need food!” “H-Huh?!” Kajex squeaked in a panic.

Without any second thoughts Rustle put the moon in his mouth before swallowing it, feeling it plop into his belly and taking care of a fraction of his hunger.

“Y-You just at the moon?!” Kajex squeaked. “Th-That hit a spot,” Rustle said as he rubbed his belly, ”B-But I’m still hungry…”

Rustle then reached out for the planet while looking down at his nose with the brightest blush on his face.

“C-Can I eat it uncle?” Rustle blushed as he awkwardly asked Kajex.

Kajex looked all around with a bright blush, weighing both options in his head before giving Rustle the answer he hoped for.

“G-Go ahead Rustle,” Kajex blushed as he looked up at him, “Y-You can eat it!” “THANK YOU UNCLE!!!” Rustle exclaimed with the brightest, doofiest smile, “You’re the bestest!”

Rustle took a hold of the planet and opened his mouth before he shoved it inside before swallowing it whole, feeling it slide down his throat.

“Crab’ll fix this with that Cradle of his,” Kajex blushed as he could feel the planet slide into his gargantuan pup’s belly, “Hopefully it’ll kick in soon.”

After a bit more effort, the planet plopped inside in Rustle’s belly right alongside the moon, a sigh of relief following afterwards.

“That feels WAY b-better!” Rustle smiled as he kicked back. “V-Very glad you feel better Rustle!” Kajex smiled.

Rustle then began to gently rub his belly with one hand and give Kajex continental head rubs with the other.

“Love you uncle,” Rustle smiled/ “Love you more Rustle,” Kajex smiled back with a tail wag.

Rustle let out one final burp with a bright blush, now drifting through space while they waited for everything to reset, which was more than likely not too far away...
