Cartoonish Growth Trade

“Gooooood morning, my cartoonish weaselbun friend!” a singing voice said as the door to the lab swung open. Alkali grinned down at Manny, totally awake for a long day of experimentation. The grey kangaroo wasn’t much of a morning person but for science he’d do anything.

Manny on the other hand looked more than a little annoyed. He rubbed the sleep from his eyes and grumbled, “Whym’ I up s’early?”

“What was that? Couldn’t quite catch that buddy. You’ll have to speak more clearly as my lab assistant,” Alkali said, totally unbothered by the grumpy weaselthing. Being a lab assistant wasn’t what Manny had planned to do today, but Al forced him into it. He couldn’t remember anymore what actually happened… something about wrecking his lab with growth? Probably. Regardless, at some point he’d done something that meant he owed Al a favor. Now the kangaroo was looking to collect: a whole day of experimentation.

He opened the door a bit wider so that Manny could walk inside. The weasel was about chest height to Alkali and still half-asleep, wobbling from side to side as he entered. He bumped a table, knocking a beaker to the ground. After that Alkali walked behind Manny and kept him properly directed, walking in a straight line back to the lab’s break room.

“I didn’t realize 7 AM was going to be too early for you bud. Could I get you some coffee?” he asked.

“Yeh, that’d be nice…” the weasel mumbled before he collapsed in a chair. Alkali didn’t wait to hear the answer though; he was hopping back out into the lab.

Today’s experiment plan was a bit half-baked, but it would do as a starting point. He grabbed two mugs off a counter and went toward the room labeled “Potion Chemistry Lab.” Five minutes later, he hopped back out with two cups full of coffee.

By the time the marsupial returned, Manny was snoring lightly. In just a few minutes he’d dozed off. Alkali frowned. This wouldn’t do at all. How were they supposed to get any science done if the weasel kept passing out? Sure it might lead to some fun shenanigans if he fell asleep and fired a shrink ray accidentally, or collapsed into a shelf of potions, but that wasn’t a part of the day’s plans. And science requires planning. Planning, and controls.

“Here you go buddy, drink up,” Alkali said, setting the cup of warm coffee in Manny’s hand.

With a grunt of acknowledgement, the snoozy weasel brought the cup to his lips and drank. Alkali watched him carefully before taking a drink from his own cup. They sat together briefly, enjoying the hot beverage, drinking in time with each other.

“Wow, this is really good. What sort of coffee is this? It’s sweet and the milk makes it really creamy,” Manny said through another slurp of the cup. The caffeine was finally taking effect. Already Manny felt more awake, more energetic, ready to face the day.

“Well I was having trouble thinking of what experiments we could try today. There wasn’t much on my to do list,” the roo said, flipping through the pages of a clipboard he’d carried in. “But I did have a bunch of leftover reagents from older potion tests. Just the extra bits that didn’t get consumed. So, I mixed them all together and put them in your coffee!”

The weasel stopped mid-sip and narrowed his eyes at Alkali. Setting the mug down he said, “You did what?”

It was a good thing that Manny wasn’t holding onto the mug because at that very moment, his arms expanded to the thickness of oak trees. Biceps exploded with muscle and his arms lengthened to the point where they were dragging on the floor. It looked as though someone had used a growth ray on just his arms, turning them into walls of muscle that any bodybuilder would look at with envy. His eyes went wide as dinner plates.

“Alkali, what- ACK,” the weasel cried as the rest of his body caught up suddenly. His legs shredded through his jeans as his head bumped into the ceiling. All parts of his body were filled out with muscle, more muscle than Manny knew what to do with. When he hunched over to rub the top of his head his hand accidentally punched a hole into the ceiling. Whoops. A little stronger than he was used to. His face turned red as he looked down with wide and worried eyes at Alkali.

The kangaroo was chugging the rest of his mug in short order. Manny hadn’t even considered what might be in Alkali’s mug. He saw the roo shudder and expand upward quickly. Well that answered any questions he might’ve had.

“Hmm, looks like there was some muscle growth, and some essence of giant in all those leftovers,” the scientist said absentmindedly flexing an arm. “Honestly I threw so many things in there I wasn’t even sure what might end up happening.”

“Alkali this isn’t what I had in mind when I- oof, stupid ceiling… this isn’t what I wanted when I agreed to help!”

The kangaroo giggled as Manny’s paws spread out wider on the carpet. “I know it’s not what you wanted, but it sure is fun to watch you squirm,” he said with a grin.

Manny couldn’t argue with that. Or maybe he could, but he was distracted with the growth of his paws. Already his feet had gone from somewhat proportional for a toon, out to the size of surfboards, and still they kept growing. It was throwing him off balance, sending several tons of beefy weasel to the ground with a flop that shook the lab. That shaking knocked Alkali off his feet too just in time for him to flop forward onto… what could only be described as an expanding, sloshing, furry package that was rapidly filling the rest of the room. Alkali was pressed into the ceiling in seconds, and shortly after that he burst straight through into the open air.

“Manny, are you okay down there? Something is wrong!” he yelled over the sound of rumbling. The weasel’s crotch expanded again with a burst upward, twice as large as before. Somewhere beneath it all Manny was smothered by his own body. Alkali wasn’t sure what could be causing such a strong reaction. Unless… he hadn’t tested most of these potions on people with cartoon heritage. Maybe something about Manny’s inherent stretch and squash abilities was causing problems. That didn’t solve anything right now though; all they could do was wait out the results and fix it once Manny was finished.

Two arms expanded from underneath the weaselcrotch, thicker than semi-trucks, and pulled Manny out from beneath his hyper bulge. Once free the cartoon was able to breathe a little easier before his paws quickly bloated to rival skyscrapers. He flexed his toes in awe, watching as the uneven growth of his own body seemed to just get worse and worse the longer he lay there.

“Mmmpf. If I could just… stand up, this would be way simpler!” Manny grunted. He shuddered, toes curling briefly before with an audible ‘pop’ Manny returned to his original proportions, granting his wish for mobility again. He was still easily 500 feet tall in total, but it was a better deal than getting trapped under his own balls.

He blushed at the thought of that again; there was plenty of hot stuff happening to turn him on, but just as much to be worried about. Better to focus on the worrying stuff first before dealing with the hot stuff. Manny stood up, taking an awkward step backward to get a better look at the ruins of Alkali’s lab. Somewhere down there was his friend. He had to find Alkali; both to turn him back to normal at the end of all this, and to make sure the kangaroo wasn’t hurt. Debris flew to the left and right with each swipe of Manny’s hand through the lab. His hands felt a little sticky and wet from the remnants of whatever solutions were down there, but no sign of Alkali.

Well, with no further leads on where Alkali went Manny’s mind switched to other pressing matters. Mostly the pressing matter of how good it felt when he stomped backward, even just to get a better view of the lab. With no supervision, Manny let himself roam freely through the cramped city streets. He only tried to walk between the buildings for a few minutes, until he got fed up with trying to squeeze between them and started to kick the skyscrapers over instead. It was much more satisfying that way he realized. With an evil grin the weasel stomped hard into a city block, flattening all of it as if a bomb was set off. More efficient than a demolition crew the weasel spent half an hour scrunching his toes into cars, buildings, people, anything smaller than his paws (which was most things at this point).

He was only somewhat aware in the back of his mind that he’d started to jerk off. Stomping around worked him up, but the majority of his attention was there rather than his erection. Alkali however was very concerned by the hand that had trapped him against Manny’s crotch. Not just because of the precarious position of being dozens of stories off the ground on his friend’s balls. That would be concerning enough. No, more concerning than that was the multicolored potions that covered Manny’s hand. They hadn’t quite absorbed yet which meant that both Manny and Alkali were soon covered in the stuff.

“This is going to go poorly,” Alkali grumbled as he felt the warming sensation of Growth Science beginning its work.

With another earth shattering stomp Manny giggled, before he squished a car between two toes. The changes to his body started slowly this time as the potions were absorbed. The ground squished beneath his paws as they expanded over the streets. His toes bloated one at a time before the rest of his foot popped into place. Soon his paws were twice as large. The pop was sudden enough to send Manny toppling to the ground, leaving a butt imprint in the ground wide enough to fit a small stadium.

Following suit, through a combination of being turned on and metabolizing enough growth potions to fill a lab, Manny’s balls sloshed and doubled in size over his thighs. His tongue lolled to the side of his mouth, panting lightly as the warming sensation became more pronounced and made his fur stand slightly on end. The fapping had to take a short break as Manny realized he was suddenly unable to reach down toward his manhood anymore. Apparently his toon body had dealt with the potions in the silliest way possible, stretching his torso out like spaghetti until he looked more like a noodle with a head, arms, and legs. He swayed in the wind briefly with the struggle of staying upright with a body this long, until another pop audibly filled the air and his torso returned to the right proportions for a professional bodybuilder.

His height had easily risen into the quadruple digits, and with another shudder he expanded up toward the clouds above. His head poofed straight through the middle of one before his chest followed suit, and soon so did his crotch. The weasel wasn’t sure exactly when he’d gotten large enough to see the curvature of the planet. Probably around the same time he realized he’d grown over the whole of the continent, with his tail in one ocean and his feet resting in the other. Manny thought that was blush-worthy enough even before he felt a particularly powerful growth spurt push his paws to new heights, far up above his head.

Bonk! Something hit the top of his toes. The weasel had to look way, way up to the top of his feet, skyscraper sized even compared to his enormity, in order to tell just what he’d knocked into. At first he thought maybe it was a satellite. That would make sense at around this size after all. But when he didn’t see anything spiraling away from his paws that looked like a satellite Manny was forced to confront the other obvious possibility: the moon was stuck between his toes now.

“Uhh. Well,” Manny mumbled, loud enough at his size that even a light whisper rumbled deep in his chest. “At least now we know what those potions to do toons, right Alkali? …hey Al, where are you?”

The kangaroo could feel the rumbling, quaking of Manny’s body but couldn’t make out the words anymore. His friend’s face was outside the atmosphere now, and with no air to transmit the toon’s sounds he had no clue what Manny said. Al shrugged and took a seat on his new seat of the weasel’s crotch. At this height and with no access to tools it might be a while before he could shrink Manny back down. That meant there was plenty of brainstorming time to figure out what went wrong… and to make it stronger for the next test.
