# When You’re Small

“Looks like another rainy day, huh Ferb?” Phineas remarked as he peered out the window.

“I knew I should’ve stayed home. There’s never anything fun to do when it’s raining, everything just gets wet!” said a somewhat soggy and annoyed Buford.

“But Buford, did you not say something similar last time it rained?” Baljeet reminded.

“Yeah, that’s right! We all shrunk down and played hide and seek,” Phineas chimed in.

“Oh yes, we had that whole musical number about the great number of fun activities you can enjoy when tiny, it was very enjoyable!” Baljeet exclaimed. “Well, mostly…”

“Well that ain’t gonna help us now, we’ve already done all that,” Buford insisted pessimistically.

“I’m sure there’s plenty more fun we can have being small,” replied Phineas, “Like building an elaborate, theme-park-worthy super-ride with cannons that shoot you all around the house and bounce you off trampolines!”

“Couldn’t you just build something like that at normal size?” Baljeet asked.

“Yes, but it would be much easier to build a tiny one,” Ferb answered.

“Guys, I know what we’re gonna do today!” Phineas declared. “Hey, where’s Isabella?”

“She’s on her way,” announced a girl’s voice from nearby. The group turned to see one of the Fireside Girls from Isabella’s troupe enter the room, shaking off her umbrella. “She’s running a little behind, but she sent me over in case you needed any help with today’s project.”

Over at Isabella’s house…

“Oh, Pinky! Look at this mess! How did you even get in to my dresser drawers? I can’t show up to Phineas’ house wearing that!”

*Woof woof!* *Sniff sniff sniff*

“Pinky no! Not on the carpet! That is not a lawn! Oh, today’s gonna stink isn’t it?”

Minutes later, back at the Flynn-Fletcher house…

“Wow, you guys set this up even faster than usual,” Baljeet remarked as the brothers finished placing the last of the many tiny cannons they had positioned around their home.

“Weren’t you listening? Tiny cannons, easy project.” Buford replied.

“But they also had to rebuild the shrinking device since it disappeared last time,” Baljeet insisted.

“Yeah, but after you’ve broken the laws of physics once, the second time is easy,” Phineas replied. “We’ve also developed these safety belts,” he continued, handing a thick belt to each of his friends before strapping one on himself. “Things got a bit dangerous last time, so Ferb and I designed these with a bunch of safety features and equipment to protect us while we’re small.”

“Alright, alright. Can we get going already? I’m ready to prove there’s nothing fun left to do when you’re shrunk,” demanded Buford.

“That would be ‘shrunken’,” Baljeet corrected, “And shouldn’t we wait for Isabella?”

“Us Van Stomms don’t wait around for no one,” he insisted. To make his point, he reached out and touched the red orb at the top of the shrinking machine. Instantly he began getting smaller and smaller until he was standing just a few millimeters tall, on the table where the starting cannon stood.

“Well, I guess that’s that,” Phineas admitted. “Do you think you could show Isabella where the shrinking machine is when she gets here so she can join us?” he asked the Fireside Girl, who had apparently been taking notes (and photographs) of everything going on.

“Affirmative!” she replied cheerfully.

“Alright then, Ferb. Here we go!”

At Isabella’s house again…

“Wow, it took forever to find that raincoat. Why did it have to rain today?” Isabella asked aloud as she opened her front door. She glanced quickly in both directions before darting across the street towards Phineas’ house. “I hope I haven’t missed too much.”

Following her normal habit, she ran to the fence and burst through the gate to the backyard. “Hey Phineas, whatcha do-” She stopped when she realized no one was there.

“Oh, good, you’re here!” Isabella turned around to see her fellow Fireside Girl peeking in through the gate with a hurried look on her face. “My mom just called and said I have to watch my little sister today. Everyone just started inside. Gotta go, sorry, bye!”

“Wait! What about the notes!? I’ll be behind!” she called after her troopmate, who was already running off.

“I’ll give them to you later!”

*Hrmn* Isabella grunted in adorable frustration. I’d better just hurry before I miss even more!

So she ran back through the gate and over to the front entrance. As soon as she was within arm’s reach, she grabbed the knob and threw the door open, expecting to already see some sort of amazing contraption. But what she actually saw was more on the surprising side.

Isabella was greeted by what sounded like a toy gun being fired and the first thing she saw was a bundle of tiny objects flying right at her face. She closed her eyes and screamed, her mouth opening wide in the process.

To her instant dismay, she felt whatever had been speeding at her, slam directly into her mouth and lodge itself at the back of her throat. Her cry quickly turned to a fit of coughing as the startled girl tried to clear her throat. Letting her body act on instinct, she swallowed whatever had been flung at her and did her best to catch her breath.

It was at that moment, as she panted in the doorway, that her mind finally processed the image of what had flown into her mouth, and she suddenly recognized the screaming faces of her friends. Her jaw fell open. Was that really just…

“Eeeeeeeep!” she screamed. Slamming the door behind her and flailing around as if she was trying to run away from her own body. That was Buford and Baljeet, and Ferb and- Phineas! she thought. They must have shrunk themselves again! Oh no, oh no, oh no-

Her panic was interrupted by a familiar, mundane sound. She paused and reached down to her hip; her phone was ringing. Bringing it up to her face, she instantly recognized the number. She quickly flipped it open and put it to her ear. “Hello?” she asked tentatively. To her distress, she heard a muffled, bass-y version of her own voice echo back to her, before another familiar voice began to speak.

“Uh, Isabella, I think you just accidentally swallowed us,” Phineas said.

Phineas… is in… my stomach? Isabella thought. Her eyes bulged a bit as her cheeks flushed red.

“Eeeeeeeep!” she screamed again, this time from embarrassment, though only she could tell the difference.

“Hey! Will you stop that already! It’s really loud!” came Buford’s voice over the phone. Isabella immediately stifled herself, but only for a moment.

“I’m so sorry guys! Phineas! I didn’t mean to- I just opened the door and-”

“Woah, Isabella! It’s okay, we’re all fine!” Phineas yelled, trying to make himself heard over the booming sound of the much larger girl’s voice.

“What are we gonna do?” she asked frantically.

“Just try to relax. Give me and Ferb a minute to think up a plan.”

Buried inside the darkness of Isabella’s digestive system, Phineas moved the phone away from his ear as he started to analyze the situation. The four of them were swimming in what they could only assume was the girl’s stomach juices, alongside whatever she had had for breakfast a few minutes ago, with nothing but the faint glow of the phone for a light.

“In retrospect, I guess putting one of the relay cannons at face level on the front door wasn’t such a good idea, huh Ferb?” Phineas remarked. “But at least the waterproofing on my phone works.”

“And we were able to keep the headphone jack,” Ferb added.

The sound of Baljeet hyperventilating began to rise over the sloshing of the Fireside Girl’s belly. “Oh, this is not good. Definitely not good,” he started to say, “The human stomach secretes numerous enzymes and considerable amounts of hydrochloric acid which at our size can certainly prove most fatal.”

“Calm down Baljeet, just reach down to your safety belt and try to find the triangular button,” Phineas replied.

A moment later, a loud hissing filled the chamber, followed by the sudden illumination of a bright light. Then the process repeated again, and again, and once more until all four of them had pressed their buttons.

“We added this feature in case an animal got into the house and swallowed someone,” Phineas explained, “It deploys a thin, transparent material over the wearer, supplies oxygen, and neutralizes any acid already inside. It also activates the self-illumination feature, so we can see.”

“Speaking of seeing, has anyone else noticed that it looks like we’re swimming in a bowl of cereal?” Buford asked. In fact the liquid they were treading did have a distinctly white color to it, with fist-sized chunks of what appeared to be hastily chewed cereal floating all around them as the pink rippling walls stirred the digestive soup.

“Woah, you’re right. It looks like Fruity Rainbow Flakes,” Phineas agreed as he examined the remains of Isabella’s breakfast sloshing around him.

“We’re swimming in an active girl’s digestive system and you two are identifying cereal brands?!” Baljeet exclaimed, obviously still far from calm. “If you thought of all these precautions, why did you not include a way to get out of a stomach?!” he asked.

“Well technically we did,” replied Phineas, “The yellow cylinder on the belt turns into a needle when you detach it, which contains a chemical engineered to induce emesis in most animals. But-”

“Well then what are we waiting for?! Let’s get out of here!” Baljeet cried, hastily grabbing the aforementioned item from his safety belt.

“Baljeet, wait!” Phineas yelled. But he was too late, the frightened Indian boy had already stuck the needle deep into the squishy stomach wall.

“‘Wait’? Why ‘wait’?” Buford asked nervously.

“The mixture wasn’t designed for use on humans! It won’t make Isabella throw us up, it’ll make her digestive system push us through faster!”

A loud gurgle rumbled through the belly, sending ripples throughout the off-white liquid within. A few bubbles came popping up ominously to the surface.

“Ughhh.” The stomach vibrated as Isabella moaned. “Guys… I don’t feel so good,” she warned. Her words were punctuated with a burp as the stomach suddenly contracted with a rush of air. The walls and ceiling were closing in, tightening against the largely unprocessed contents of her belly.

Baljeet began to panic again, screaming as he splashed around. Even Ferb seemed somewhat frightened.

“We’re okay right? Tell me we’re okay,” Buford pleaded.

“Don’t worry, we’ll be fine,” Phineas called back over the constant gurgles and groans. “Isabella! See if you can find something to swallow that we can grab onto: a piece of string, a line of dental floss, some spaghetti, anything!” he yelled into his phone.

Isabella hesitated for a moment, frozen in a state of awkward embarrassment, mixed with concern, mixed with nausea. But she forced herself into action. “Right, I’m on it,” she replied.

That had not been a good idea.

As Isabella rushed towards their bathroom, in search of some dental floss, her sudden motion turned the already choppy seas of her tummy into a typhoon. Waves of digesting milk crashed on top of her occupants, sending them tumbling around her belly as it quickly began to squeeze its contents further along. The Fireside Girl’s belly gurgled relentlessly as she bounded up the stairs and around corners, distracting her with strange and vaguely uncomfortable sensations. Finally, she reached the bathroom, tearing through cabinets and draws until she found what she was looking for.

“Alright Phineas, I found some dental floss, I’ll start swallowing it!” she said. She held the phone up to her ear, but the only response she could hear were the amplified groans of her own belly as she felt it working its contents. Even more worried now, she pulled a long length of floss from the box and stuck it in her mouth, swallowing as quickly as she could. Honestly, she couldn’t tell if it was really going down like a rope or just wadding up somewhere beyond her tongue, but she kept feeding the mint-flavored line down her throat until she came to the end.

“That’s all of it,” she announced, “I’m gonna start pulling it back up now.” Still no response. Anxiously she started pulling the thin strand of material back out of her mouth. She felt it tickle as it slid unnaturally through her gullet, but not enough to cause her to cough or gag. With every tug she grew more worried, more anxious, until finally she felt the end of the line slide out over her tongue.

She stared for a moment at the bare end of the floss as it dripped onto the bathroom floor. “Oh no… Phineas…” she whined mournfully.

“Isabella!?” came a voice from her cellphone speaker, accompanied by a few sudden splashes and the occasional squelch.

“Phineas! Are you okay!? Should I swallow the floss again?” Isabella asked with clear concern.

“Yeah, we’re okay,” Phineas replied, “But I don’t think we’re in your stomach anymore…”

Inside…

“What do you mean we’re not in her stomach anymore? Where are we then?” Buford asked.

“I believe Phineas means to say that we have been passed into Isabella’s duodenum, and unfortunately he seems to be correct,” Baljeet answered.

“Her duo-what-now?”

“Her small intestine; the part of the digestive system that comes after the stomach,” Phineas simplified.

A sudden contraction of the narrow tube they found themselves in sent them falling over one another as they were abruptly shoved along with the rest of Isabella’s previous meal.

“So how are we supposed to get back out now?” Buford asked, though it wasn’t clear if he’d actually understood or not.

“We cannot, the pyloric sphincter will undoubtably be tightly shut and at our size we have no chance of opening it; it is hopeless,” Baljeet announced in despair.

“Don’t give up yet Baljeet, I’m sure we can think of something!” Phineas encouraged. “Let’s see if we can get back to the sphincter, maybe we can figure something out.”

Several intestinal contractions later…

“Wow Isabella, you have one tough gut,” Buford admitted, panting after his latest attempt to fight backwards through the long organ. As far as any of them could tell, they hadn’t done anything but continue to slide further along.

“What if we got her to swallow some magnets and she used another magnet to help push us back?” Phineas suggested.

“But how would the magnets she swallows catch up with us?” Baljeet questioned.

“And not to be selfish or anything, but wouldn’t that kinda hurt?” Isabella added.

Numerous gurgles later…

“If only we had some of our tools, Ferb might be able to make something using some parts from our suits,” Phineas speculated.

“The suits that are keeping us alive? That does not sound like the best plan,” Baljeet countered.

A few groans, rumbles, and a squelch after that…

“Hey look, the tunnel’s getting bigger!” Buford exclaimed happily.

“That is not a good thing, Buford,” Baljeet replied in an aggravated tone.

“What do you mean? A bigger tunnel means more room to think, right?” he replied.

“Do you not understand anything about basic logic or the layout of the digestive system?” Baljeet snapped.

“Come on guys, fighting is not going to help us,” Phineas reasoned.

“It is his brashness which got us into this situation in the first place! If he had just waited for Isabella-”

“Hey, I’m not the one who stuck that crazy needle into the wall and-”

*more noisy arguing*

“Come on guys, you’re gonna give me another bellyache,” Isabella complained.

Many haustra later…
(I know fancy biology words… because I have Google)

“Um, I really don’t want to point this out, but… has anyone else noticed how brown and… solid things are getting?” Baljeet asked.

“Um, yeah, I was kinda hoping no one would bring it up,” Phineas answered.

“Brown? Solid? Wait do you mean-!? Ahhhhhh! No! No no no! Someone get me out of here right now!” Buford screamed.

“Buford calm down! You’re wearing a protective suit, nothing’s going to touch you,” Phineas told him.

“Well you seem strangely okay with being packed into a log of feces,” Baljeet pointed out.

“Hey! What’s that supposed to mean? I don’t see you freaking out about it,” Phineas replied.

“Well ‘freaking out’ is not going to help us,” he answered.

“Exactly! So help me calm him down,” Phineas insisted.

He tried to reach over and grab Buford, who had been flowing along with them a few arm-lengths away, but none of them had really tried to move in a while and he found the once fluid substance around him had indeed become much thicker. Though that didn’t seem to be a problem for the colon, as another contraction forced them further along its length.

“It’ll be okay Buford, we just have to let nature take its course and we’ll be out in no time,” Phineas offered.

“Yes, it’s all purely natural,” Baljeet agreed.

For a moment the (normally) large, grey boy stopped yelling, only to start sobbing a few seconds later. “Awww, we’re gonna be poop!” he whined. Both Baljeet and Phineas sighed.

“I think you’re all worrying too much about what you’re going out with, and not enough about where you’re coming out from.” Ferb suddenly interjected in his trademarked dry tone. He, unlike everyone else, had realized exactly how things would go once they had been carried past the stomach. And since he hadn’t spent any time bickering, he had also realized exactly how and where things would end.

Everyone, even Buford, suddenly went quiet and began to blush. And then Isabella spoke, with a blush far deeper than any of her friend’s, though no one was around to see it.

“Um, guys, I need to use the bathroom.”

Isabella, who had been doing her best to relax and stay still on the living room couch, finally felt the urge she had been dreading. She had been listening to their attempted escape plans while silently tracing their progress through her innards with the help of the Fireside Girl Handbook. She could tell by their voices, movements and the pressure in her lower abdomen exactly where they were. And she had realized all too well what she was going to have to do. Now, she stood up again and nervously turned towards the stairs. She climbed them slowly, both to keep from jarring her occupants too much and in an attempt to desperately postpone the inevitable.

“Guys, I’m sorry about this whole thing. If I had just gotten here on time…”

“No, it’s not your fault, we should have planned things more carefully,” Phineas replied.

The faint sound of a door opening and closing made it through the walls of Isabella’s body, followed by the familiar clank of a toilet seat.

“Phineas…” she said, turning redder than an apple, “Just… try not to look…”

----External View----

Isabella reached down to the hem of her dress with one hand and lifted it up, exposing her pink panties to the currently empty bathroom. With a practiced, casual movement, she reached down with her other hand and slid the underwear down her legs to her knees. A perfectly normal action she performed every time she used the toilet, except now it filled her with apprehension.

She bent down and rested her bare bottom on the seat, her interior muscles primed for action. She closed her eyes for a moment. Okay Isabella. Whatever happens, happens. Let’s just get this over with, she told herself. Of course she was suppressing the metaphorical elephant in the room, the thought burning at the back of her mind: Phineas is going to see my butt!

Butt there was nothing she could do about that now.

*inhale* … *exhale*

It all started with her bladder. She had needed to pee for a while now, but had held it in for obvious reasons. Now that she was allowing her body to release, that was the first to go. The translucent yellow liquid sprung to life as a stream from the small slit between her lower lips, emptying out into the bowl below with a distinctly familiar sound. A sound she knew could be heard by all her friends- by Phineas- from their location not very far away from its origin. Her blush started to return as the thought floated through her mind.

After a few seconds, her bladder seemed to run dry and she felt her bowels ready to release their eager load. She thought she ought to warn her friends what was coming, but found she was too embarrassed to speak. So she just took another deep breath, and pushed.

She heard a few tiny, muffled complaints as her colon compressed, forcing the waste that had accumulated within up against its long-awaited exit. She felt her anus begin to pucker, and she pushed again.

*phhhrt*

Isabella nearly gasped. She was completely mortified, but she forced herself to continue. Gulping audibly, she took another deep breath and began to push again.

*phhhhhhrt*

Another bout of gas escaped her rear, but now she felt something solid pressing up against her exit. She pushed again and this time she could begin to feel the head of a smooth log slide its way past the rim of her pucker. She kept up the pressure, feeling the turd continue to inch forward until finally-

*plop*

The first tiny clump of poop had made its exit, and from that, she started on a roll. She almost just let her body take over, nearly too embarrassed to consciously monitor the activity, but even so she could still feel as every lump or log slowly slid its way out of her rear and fell down into the bowl below- knowing full well that any one of those feces could in fact be one of her friends.

After what seemed like an unbearably long time, she felt her rectum begin to empty. Feeling the impending relief at having this whole thing behind her, she gave a few more firm pushes, expelling the last of her waste. She breathed a sigh of relief, but as she did so, she suddenly felt a further pressure in her bladder, as if emptying her bowels had somehow reminded her bladder that it was not quite empty itself. Without thinking, she allowed the yellow liquid to flow once again, a new stream falling from her privates as the tender redness within peeked out onto the shadowed bowl.

She gasped again as she realized that her friends were undoubtably below her at this point, and that they had definitely just seen, or at least heard- maybe even felt- her releasing the last of her bladder’s contents onto their turd-covered bodies.

----Internal view----

“Just try not to look,” she had said. That had made Phineas blush, hard. Ferb was right, he hadn’t really thought about where he was about to come from. I mean, there was a reason that boys and girls had separate bathrooms, he knew that. Of course he was incredibly smart and resourceful for his age, so he also knew… some other things… but not very much. And he had certainly never seen anything before. He heard his heart begin beating harder, or was that just Isabella’s pulse? He wasn’t sure.

He heard her take a deep breath. And then it began. A familiar trickling sound made its way to the ears of the fecal-encrusted boys.

“Aww man, she’s peeing,” Buford whined.

“Oh, this is going to be most disturbing!” Baljeet agreed.

Phineas just stayed silent, like his brother, thankful that no one could read the thoughts going through his head.

Then, as suddenly as it had started, the trickle stopped. There was a moment of silence, and then they heard Isabella take a deep breath.

“Brace yourselves!” Baljeet warned, moments before the surrounding muscles contracted around them, squishing them thoroughly into the surrounding brown matter. Phineas could hear his friends make a few attempts at cries for help, but the feces were so dense that even he couldn’t make out what they were saying.

A loud, booming sound came from somewhere close by. Like a rush of air slamming a wet door. It took Phineas a moment to figure out what that sound had been, and at that moment he realized two things: one, a fart had never been less funny; and two, a fart had never sounded scarier. A moment later the sound came again, lasting longer this time, and he felt all the free space he had left disappear as he was sandwiched between the roof of Isabella’s colon and a thick log of her feces.

Finally, he felt himself begin to slide forward as the muscles of his friend’s bowels pushed at the rear end of the log. A few moments later and he heard a distant *plop* as what was presumably the first piece of her excrement made its way out of her anus.

That’s right, he had almost forgotten already in all the commotion that that was where he was headed. He was going to come out Isabella’s butt.

One push at a time, he could feel himself slowly making his way further along. He had no idea how close he was, and he no longer had any ability to move. It was all up to Isabella now, she had to get them out- the only way she could.

*plop* *plop* *plop*

Finally, Phineas felt his head press up against an exceptionally tight ring of muscle. Realizing this was the exit he had been waiting for, he braced himself for what was to come.

Isabella pushed again.

Slowly, Phineas’ face slid out of his friend’s puckering anus, his body mostly buried in brown. His world was dimly lit by the light that leaked in from between Isabella’s legs, but otherwise all lay in shadow of her (relatively) massive rear as it rested above him. And Phineas, like it or not, had the perfect view.

He had been excreted face-forward, that is, facing in the same direction as Isabella, so directly in front of him was that exact thing that she had hoped he somehow wouldn’t see. And he couldn’t help but look.

Her slit stretched out before him like a smooth red valley in her otherwise immaculate crotch, still dripping with a few stray drops of her urine as she worked to expel him from her body. She pushed again, causing him to slide out a little further, providing him an even better view. Now he could start to look up into her. He knew he shouldn’t be doing it, and he was blushing intensely, but he just couldn’t look away.

Phineas stared at his friend’s virgin slit for what seemed like an eternity, until suddenly he was brought back to his senses by the sudden sensation of being dropped. Of course there wasn’t much he could do about it. He fell, rather unceremoniously, down into the dirty toilet water, making a sizable splash before bobbing around a bit.

Fate had always favored him, or so Candice had complained, and it seemed now was no different. Because as the turd he was embedded in came to rest, floating on the surface of the water, he found himself laying face-up, staring at the looming buttocks that had just pushed him out.

And so he watched as his friends were expelled, one by one, splashing into the water beside him. He couldn’t really turn his head to see if they were okay, but honestly, he didn’t really want to. Eventually, though, he watched the last piece of turd slip from Isabella’s pucker, briefly revealing the gaping tunnel of her rectum before her outer ring relaxed, closing it off from view.

But just when Phineas- and all of his friends- thought that was the end, they were suddenly met by a stream of yellow liquid which had abruptly sprung from between Isabella’s innocent lips. He watched, riveted, as the tiny hole from within the slit sprayed the liquid from her body out into the bowl, before the stream gradually slowed to a stop.

----Internal View End----

Isabella quickly stood, practically bolting upright and scrambled to pull her underwear back up to cover her nethers, unwilling to actually turn and face her friends until she was fully clothed again, regardless of what they had just seen. When she did finally turn around, all she could do was stare in a sort of mortified fear. Her friends were floating there in the yellow-tinted water, packed into logs of her excrement, which still held bits of her breakfast thanks to its speeded trip through her belly.

She noticed Phineas, lying face up with his body submerged in brown. He was blushing, hard and wouldn’t meet her gaze. That just made her blush harder.

OH MY GOD HE SAW IT! she screamed in her own head.

“Will you please get us out of here already!!?” Baljeet screamed, loud enough that she could hear him even at his current size.

“Oh, um- right,” Isabella stammered. She looked around the room for a moment. “Let me, uh, go find something to fish you guys out,” she said, relieved at the excuse to leave the awkward space. She disappeared from view, her footsteps echoing as she dashed away.

“…Aren’t we all a little young to have just seen that?” Buford asked. There was a moment of awkward silence.

“Yes, yes we are,” they all answered in unison.

Not much later…

“Okay, that is the last time I agree to be miniaturized,” Baljeet declared. The boys each wore a pair of Phineas’ or Ferb’s clothes, now that they had each bathed and thrown their soiled clothes away.

“You said it,” Buford agreed.

Phineas just stood with a silent frown on his face, gazing at Isabella who sat on her own, a fresh blush coming to her face every now and then as she undoubtably relived the recent experience.

Ferb put a silent hand on his shoulder.

“You’re right, Ferb. I’m gonna go see if I can cheer her up,” he decided. As he approached his friend, his mom popped into the room.

“Hi kids, I’m back from the store. Does anyone want some brownies?” she asked.

“NO!” everyone shouted.
