Canterlot High Monster Girl Mayhem!

Canterlot High Monster Girl Mayhem!

By: Nicole Sunstone

“Alright students!” Miss Cheerliee announced to the crowd in the auditorium. “As you all know, the Canterlot High science fair is coming up! The group which can impress our panel of judges will win first prize!”

Sunset smirked as she looked back at her group of friends. “Piece of cake.”

“Not so fast, Sunset!”

She turned back around to see Trixie standing in front of her in her usual majestic pose. “The Great and Powerful Trixie will be sure to win the competition with her scientific greatness!”

“Oh yeah? I never knew you were into science, Trixie.” Sunset responded with a friendly expression.

“Please! If it’s anything you must know about Trixie, it’s that anything you can do, Trixie can do better.” Trixie boasted, snapping her fingers as Lavender Lace and Fuchsia Blush took a hold of Fluttershy and Rainbow Dash from behind Sunset’s back.

“Hey! What’s the big idea?!” Rainbow Dash shouted, trying to pull the girls off of her. Fluttershy squeaked as a scrawny duo of Snips and Snails gently grabbed her arm.

“Trixie will need these two for her experimentation. Seeing as you six have a history of using magic, it’s only fair that every student, including Trixie, has the same advantage.” Trixie explained as Rainbow Dash continued to struggle while Fluttershy sunk behind the lanky Snails.

“Oh, well I guess that’s fair,” Sunset admitted, still trying to think of what their presentation would be. “But I think it’s best if magic just stays out of the competition full stop, wouldn’t you agree?”

“The Great and Powerful Trixie doesn’t trust you on that front,” she said smugly before snapping her fingers to make her exit.

“Well, Trixie’s as boastful as usual.” Applejack commented as Pinkie Pie hopped up behind her, smiling.

“She does have a point. I just hope she doesn’t do anything too extreme to them.” Sunset said worried as another student with purple hair and aquamarine highlights came up, brushing her hair curl out of her face. “Hello there! Are you new?”

“Uh, yeah. Something like that.” She answered as Trixie magically appeared behind her with a devious grin on her face.

“I would like you all to meet Starlight Glimmer, Trixie’s new assistant in magic!” Trixie announced as Starlight waved with a small smile. “Starlight is from out of town but she has agreed to help Trixie in any way she can.”

“Well, I wouldn’t say in any way but I do want to try to win the science fair.” Starlight explained.

“For Trixie,” Trixie added.

“For Trixie?” Sunset repeated, crossing her arms.

“It wouldn’t hurt to have someone else in the competition, right? And maybe we can all be friends afterward?” Starlight suggested, smiling at Sunset.

Sunset smiled as Trixie nudged Starlight aside. “The Great and Powerful Trixie doubts that very much.”

“Well Starlight, you make a good point. Even though you’re teamed up with Trixie, I suppose a couple of us can help you out. Girls?” Sunset asked, looking at Applejack and Pinkie.

“Why not? I mean if Trixie here has Dash and Fluttershy, we can help you out with your sciency stuff.” Applejack walked over to Starlight as Pinkie bounced over right behind her.

“Yay! Friendship science! We’re gonna have the best time like when we first met Sunset! You know, you two are kinda similar!” Pinkie pointed at the two girls, noticing their similarities. Starlight and Sunset looked at each other, brushing their curled hair out of their faces before smiling.

“Enough chatter! Trixie needs to take her assistants to where she can work in peace!” Trixie interrupted as her team took Rainbow Dash and Fluttershy with them, pushing Starlight out of the room with Applejack and Pinkie Pie following close behind her. Sunset rolled her eyes before looking back at who she had left on her team, which was Rarity, focused on her phone.

“So Rarity, ready to do some science?” Sunset asked enthusiastically.

“Of course, darling, but aren’t we a little short staffed considering that Trixie and Starlight have four of our friends and you only have, well, me,” Rarity asked, noticing the emptiness around her.

“Yeah, but seeing as I’m probably the best scientist in Canterlot High, I don’t think we really need anyone else.” Sunset boasted before chuckling to herself. She was starting to sound a bit like Trixie.

“I dunno, I would feel much more comfortable if we got at least one more person in our group to help out with the project.”

Sunset looked around the room. She noticed the candy-haired girl in a loving embrace with a minty-green girl with a cool green hairstyle. Her gaze traveled to a wall-eyed blonde girl waving happily at her. Lastly was one of the eco-kids giving her a smile behind her messy braids.

Sunset pondered as she felt a vibration from her cell phone in her pocket. Suddenly, the answer hit her!

“Come on, I know where we can get some help,” she said confidently, leaving the room, Rarity following close behind.

Standing outside by the Canterlot statue, Sunset carefully wrote her message into a book with her Cutie Mark on the cover. The book’s magical powers allowed her messages to be sent to an identical book back in the magical world of Equestria, where Princess Twilight could read them. Most of the time, Twilight has been too busy having adventures of her own to answer Sunset’s calls to come back to Canterlot High, but she hoped that there was a slight chance that Twilight would answer this time around.

“There, that should do it,” Sunset said as she closed the book shut. Rarity looked on, skeptical on whether the plan would work or not.

“Your big idea was to recruit the Princess Twilight to help out at the high school science fair?” Rarity asked.

“It’s worth a shot, right?” Sunset answered, remembering when Twilight met up with her alternate self after a long period of not answering Sunset’s messages.

“Yes, but we don’t have much time to waste! Princess Twilight could take hours if not days to come back to Canterlot High!” Rarity whined as the portal on the statue shimmered, with a shining and peppy Twilight Sparkle appearing out of the mirrored surface.

“Did somepony say science?” Twilight asked cheerfully, looking over at Sunset. Sunset smiled back with a soft look at Rarity, who had already taken the liberty to hug the visiting Twilight.

“Umm, Trixie?” Fluttershy asked as she followed the Great and Powerful Trixie through the animal shelter where she volunteered. “What are we doing here?”

“The Great and Powerful Trixie has a great idea that requires animals!” Trixie shouted, causing a bluejay to squawk next to her. Trixie carefully plucked one of her feathers before tossing it aside for one of her assistants to catch.

“Oh dear! Please don’t hurt them!” Fluttershy cried, rushing over to make sure that the bluejay was unharmed from Trixie’s grabby little fingers.

“Has anyone ever told you that you’re a loudmouth?” Rainbow Dash asked, following Trixie into the reptile exhibit.

“Trixie has never been told such things other than from those who are jealous of Trixie,” Trixie commented, looking through the various terrariums for the right reptile.

“Right, so someone has told you.” Rainbow Dash added, her expression displaying her unamused expression of being a part of Trixie’s boastful team.

“There is no need for Trixie to hear more squawking from bird-brained minds.” Trixie waved as she picked up a snake from one of the glass cases, unaware that the sign on the front said that the animal was venomous.

“Uh, Trixie, you might-” Rainbow Dash stopped, thinking of what Trixie was getting herself into. “Actually, no, go ahead. Don’t mind me.”

Rainbow Dash walked off to meet up with Fluttershy as Trixie smiled at the toothy snake in her grasps, pulling out a small test tube from her jacket before teasing it in front of the reptile. The snake bit down on the top of the tube as Trixie pumped it with her hand on his scaly body. Squirting his venom into the tube, Trixie dropped the snake back in the terrarium as he slithered away.

“Trixie has gotten what she needed from the animals!” Trixie announced as more birds squawked at her. Marching out of the shelter, she tossed the fragile test tube into the hands of one of her assistants as Rainbow Dash and Fluttershy followed behind.

“Wait, Starlight Glimmer?” Twilight asked as Sunset got to work in the lab for her project. Rarity nodded, wearing a very chic lab coat as she sat back to talk to Twilight.

“That’s what she said her name was. I had never seen her around Canterlot High before.” Rarity commented, keeping her distance from a very hairy tarantula in a glass case next to her on the counter of the lab.

“I had just met up with a Starlight Glimmer in Equestria! Remember when I told you all about the time-travel loop that threatened the state of Equestria?” Twilight asked, looking at both Sunset and Rarity.

“It’s really hard to remember the times when you don’t explain Equestria as being in a state of crisis,” Sunset answered, using her pipette to take a sample of saliva from the lab frog’s mouth.

“Usually because of some spell went wrong or an evil entity bent on destroying civilization,” Rarity added, looking at her phone.

Twilight chuckled sheepishly. “Right, but Starlight is good now! And she’s friends with Trixie which explains the turn of events in this dimension as well!”

Sunset pulled off her goggles and span around in her chair happily, holding a test tube filled with the frog’s saliva. “Got it!”

“Excellent! What is our hypothesis?” Twilight asked eagerly.

“Umm, I was thinking of something with genetic engineering but I’m not entirely sure how well it’ll work.”

“Frogs make great test subjects, but what should we do with him? For the sake of science, of course.” Twilight explained as Rarity shrieked in the corner. The two looked at her moving as far back from the tarantula in the case as possible.

“If we are done using the hairy spider on eight legs, I would very much appreciate it if it was removed from the lab!” Rarity requested as an idea formed in Sunset and Twilight’s heads.

“Thanks for letting me check out the farm, Applejack!” Starlight said, walking through the open barn of the Apple Family Co-Op.

“Aww shucks, wasn’t nothing.” Applejack commented, walking beside Starlight as she scoped out the various animals on the farm. “What were you thinking about doing for the science fair, anyway?”

“I think something with horses would be a good place to start. Do you have one around the fields?”

“Sure do! Gosh, I love riding her on the weekends. I’ve offered to take Rarity here once or twice, but she’s a stickler for mud.” Applejack answered, making her way to the stables. “Here she is, Miss Palomino.”

The brown-coat horse neighed at Starlight, giving her a smile with her long face. Starlight carefully ran her hand through her long, blonde mane and looked back at Applejack. “She looks just like you!”

“Am I supposed to take that as a compliment?” Applejack chuckled, patting Palomino on the side. Starlight laughed as well, looking around the stables a bit.

“Do you have any stallions around as well?” Starlight asked as Applejack brushed the mare’s mane.

“Not yet. Been in talks with Big Macintosh about getting a retired racehorse from the track up north, but nothing yet. My girl here is enough of a horse for me though.”

“She certainly is a beautiful animal.” Starlight smiled, looking at her hand covered in horse fur. Taking out a plastic bag, she carefully brushed the strands of fur into it. “Maybe we can do something with her for the science fair!”

“Well, I suppose we could. As long as whatever sciency thing isn’t gonna hurt her.” Applejack patted the mare before leaving the stables with Starlight.

“Trust me, Applejack, I would never want to hurt your prized horse.” Starlight said confidently before running into a mud-covered Pinkie Pie. “Ahh!”

“Look what I found!” Pinkie said cheerfully, pulling a ruby slug from the mud in her hands. Applejack chuckled as Starlight pulled away. “Isn’t he cute!”

“Uh, yeah! Don’t you think you should get cleaned up?” Starlight suggested as Pinkie put the slug on her cheek, as it spreads the mud around her face.

“Oh yeah! Can we keep him? Please?” Pinkie asked with big puppy-dog eyes.

Starlight looked over to Applejack who just smiled and shrugged. “Yeah, as long you clean up first.”

“Yipee!” Pinkie cheered before running off to the nearest shower.

“Is she always this excited about something?” Starlight asked, looking at Applejack.

“Almost definitely. Come on, let’s think this project through over a few cups of freshly squeezed fizzy apple cider.” Applejack rested her hand on Starlight’s back, leading her into the house.

On the day of the science fair, each one of the teams had finished their projects and were ready for their presentations. Sunset, Starlight, and Trixie were the most enthusiastic entrants of the competition, with some of the other students having their own entries based around more basic projects like a potato-muffin battery and baking soda volcanos.

Starlight and her group went over to their table while Applejack looked at the notes for the spray bottle she was holding in her hand.

“Wait, shouldn’t Palomino be here for the experiment? I mean, how else are we going to know if it works?” Applejack asked, trying to understand the purpose of the concoction in her hand.

“Oh Applejack, do you want a horse in the gym? I think she would more freaked out with all the students that the test results would be heavily skewed.” Starlight replied, double checking her notes for the project. Pinkie Pie slithered up behind Applejack, catching her off guard.

“Wha! Pinkie Pie! What in tarnation are you doing sneaking up on me like that?” Applejack asked, looking at the girl with the slug leaving a slimy trail on her cheek.

“I wanted to see what it would be like to act like Timmy! Ooh, is this new perfume?” Pinkie asked quickly, snatching the spray bottle of Starlight’s solution out of Applejack’s hand.

“Pinkie! No! Don’t spray that!” Applejack warned as Pinkie sprayed her face with the funny-scented liquid generously. Licking her lips, Pinkie’s face scrunched up at the flavor.

“Eww! What was that?” Pinkie stuck her tongue out as Timmy continued to apply a line of slime to her cheek.

“The experiment, Pinkie!” Applejack exclaimed in exasperation

“Everything good to go here?” Starlight asked, looking at the confused Pinkie Pie sticking her tongue out.

“Yeah, except Pinkie sprayed herself with the horse solution! Who knows what’s going to happen to the poor girl.” Applejack shrugged before grabbing the bottle back from Pinkie.

“Well, keep an eye on her, but it’s almost time to start!” Starlight said, putting on a white lab coat as students started to crowd around their table.

“Do you really think this is going to work, darling?” Rarity asked as Sunset walked through the gym towards their table, holding onto the unmarked test tube of frog saliva.

“I’ve checked the facts and given the solution that I have produced with Twilight’s help, this should be a prize-winning breakthrough in genetic engineering!” Sunset answered, confident in her project.

“Great! But where is the solution for the project?” Rarity looked around, not seeing Twilight anywhere near them.

“Twilight’s already at the table. We just need to get there before-”

Not looking where she was going, Sunset crashed right into Trixie in the middle of the gym. The two girls felt their test tubes fall out of their hands as the vials rolled next to each other on the floor.

“Oh my gosh, I’m so sorry Trixie!” Sunset apologized, trying to help her up. Trixie chuckled before moving to a full-on cackle.

“You must be desperate to sabotage the Great and Powerful Trixie if you’re willing to make her drop the most important piece of her project!” Trixie bellowed, snatching one of the test tubes off of the floor. Sunset picked up the one left over, noticing that they looked almost identical.

“It was an accident, I swear.” Sunset tried to reason as Trixie flipped her hair back, walking over to her own table in the gym.

“Is everything ready for Trixie’s great performance?” Trixie asked, looking at the meek Fluttershy and disgruntled Rainbow Dash.

“I don’t understand this project at all.” Rainbow Dash commented, looking at the beaker filled with a strange-colored liquid. Trixie grabbed the beaker and poured the contents into a spray bottle, shaking it up.

“If you listen to what Trixie says when it’s showtime, all will be revealed!” Trixie boasted, spraying Rainbow Dash with a cloud of the solution. Rainbow Dash coughed as the solution seeped into her face and skin.

“What’s the big idea?” Rainbow Dash coughed as Fluttershy rushed to her side. “What was that stuff?”

“The bird part of the project, now hush!” Trixie shushed, cueing up the drumroll on the side of her table.

“Are we ready to go?” Sunset asked, seeing that Twilight pulled up her hair to examine the intricate setup on the table for the main beaker of the solution. Several diagrams of the tarantula and the frog were posted behind them to explain the intricate parts of the experiment.

“You’ll have to ask the test subject yourself.” Twilight smiled, looking at Rarity. Rarity looked around confused at the two girls staring at her.

“Test subject? What? No! I did not agree to this!” Rarity refused as Twilight poured the solution into an old perfume bottle, fit with a poofy atomizer at the top.

“Come on Rarity. We’ve checked the math twice over. This won’t hurt a bit.” Sunset pleaded, offering the perfume bottle to Rarity.

“If my calculations are correct, and they usually are, then after you spray this, your arachnophobia will be severely lessened!” Twilight cheered happily, letting her hair down.

“And how do you intend to test that?” Rarity asked before Twilight sprayed the atomizer at Rarity, leaving her in a cloud of the solution.

“All good science needs steps! Sunset, do you have the frog DNA?” Twilight asked, pouring the solution back into the scientific setup on the table.

“Yeah, it’s right here!” Sunset said, handing her a test tube.

“Alright, we’re ready to go then!”

“Girls and boys! Esteemed students! Gaze upon the science fair project of the Great and Powerful Trixie!” Trixie announced as the crowd of students walked up to see her project. Trixie waved her hands down the stage as Rainbow Dash stood on one side scratching at her arms while Fluttershy squeaked at the other side of the table as she spots students looking in her direction.

“For Trixie’s project, she will be presenting the connection between avian and reptilian species!” Trixie pulled away from the covers on the posters explaining the prehistoric connection of the DNA shared between birds and reptiles and their ancestors. “In this instance, Trixie has exposed the brutish Rainbow Dash to the effects of avian pheromones!”

Rainbow Dash continued to scratch at her arms, looking over at Fluttershy as Trixie continued to address the crowd.

“To show the connection her DNA with the reptilian subject, Trixie will add the snake venom to the solution and apply it to the timid Fluttershy!” Trixie poured the contents of the test tube to the beaker before pouring it back into a spray bottle. Spritzing the liquid on Fluttershy’s face, Trixie looked to the audience as a small applause was made.

“Umm, Trixie?” Fluttershy coughed, feeling a frog in her throat.

“What is it, Fluttershy?” Trixie sneered off to the side of her table.

“I don’t feel so good…”

“Hear hear, students!” Starlight announced, feeling comfortable in addressing the crowd of students. “For my science project, I will be taking the love and affection of Applejack and her prized horse, Palomino!”

The crowd murmured with intrigue as Applejack smiled and waved, pointing out the notes and facts listed on the posters that Starlight and Pinkie Pie had made, covered in glitter.

“Now, seeing as we couldn’t bring a live horse into the gym, it’ll be a bit hard to quantify these results. But I am confident that Applejack’s connection with Palomino will pull through to show a more deepened connection!”

Starlight picked up the spray bottle as she glanced over to Pinkie Pie sitting in the chair, looking as though she was melting in her seat. Her face was covered with a thin layer of jelly-like slime as the slug perched on top of her poofy hair. Shaking her head, Starlight went back to the table and presented the bottle, spraying a cloud of the solution on Applejack.

“With the solution applied, the connection between horse and girl should be amplified by thirty times!” Starlight said confidently as Applejack closed her eyes.

“I… I see her. Well, I see through her eyes!” Applejack spoke with her eyes closed. “There’s Big Macintosh working in the fields. I can see Apple Bloom climbing the trees in the orchard! I feel everything about her!”

The crowd applauded as Applejack instinctively whinnied, pulling her hair free from her hair tie as she knocked off her Stetson hat. Starlight looked on, proud of her project as Pinkie Pie slithered back up next to her.

“Starlight?” She asked, speaking very slowly and resting a hand on her shoulder. Starlight pulled Pinkie away, noticing the amount of slime coming from her hand.

“Pinkie! What in the world?” Starlight whispered, noticing Pinkie’s hair drooping down and dripping with slime.

“I think something is wrong with the sciency thingy…”

Fluttershy shook as a frog-like ribbit escaped her mouth. Her legs began to feel like jelly as she fell back into a chair behind the table. Trixie’s forehead began to sweat as she looked back at the crowd before seeing Rainbow Dash’s scowling face in front of her.

“What did you do to her?!” Rainbow Dash squawked, waving her arms around.

“The… the snake venom should have been diluted to a harmless amount in the solution! Trixie did not poison poor Fluttershy!” Trixie defended herself, showing the container to the enraged Rainbow Dash.

“You’re the scientist! You need to fix this!” Rainbow Dash poked her finger into Trixie’s chest, her nails starting to grow out.

“Yes, yes, there is a way to fix this!” Trixie looked around at her table for the right chemicals for the solution. “This was not a part of Trixie’s calculations!”

Rummaging around the table, Trixie picked up a lone blue feather and stared at it. “Where did this come from?”

“...And that’s how arachnophobia is usually handled in the field of medicine,” Twilight concluded with the prologue of Sunset’s project notes. A few of the students clapped, although most of them yawned. Rarity blinked, trying to keep her eyes open as she scratched at the sides of her stomach.

“However, with this solution, we will take the mindset of the amphibian and apply its less-threatening view of the arachnid. Frogs have no quarrels with spiders, so we should be able to cure Rarity’s crippling affliction.” Sunset explained as Twilight began to mix in the contents of her test tube into the solution and refill the perfume bottle. Spraying it twice at Rarity, her nose twitched as she lifted her chin.

“A-choo!” Rarity sneezed, spraying her share of the mixture onto Twilight’s face. Twilight quickly rubbed her face clear of the germs before the solution settled onto her. Rarity’s eyes shot wide open as the second set of arachnid pheromones began to settle inside of her.

“Are you okay?” Sunset asked as Twilight’s eyes began to change into snake-like slits. Twilight blinked, trying to adjust to the exposure of the solution.

“I knew I ssssshould have worn a pair of sssssafety gogglessss.” Twilight hissed out, rubbing her arm against her eyes.

Rainbow Dash squawked loudly as she pinned Trixie to the table, her arms starting to cover in blue feathers. Trixie looked on in horror as Rainbow Dash’s talons dug into her shoulders.

“What’s going on, Trixie? This wasn’t part of the project!” Rainbow Dash shouted, flapping her arms as they grew to form primary feathers.

“I… I don’t know! This is not supposed to happen!” Trixie looked around, most of the students watching and taking video on their phones as Rainbow Dash’s wings grew out of her arms.

“Trix-ie!” Fluttershy belched, trying to take control of her instincts. Her legs wobbled as they merged together, ripping away her shoes and socks. “You re-al-ize that we are not reg-ul-ar students?”

“What? What does that mean?” Trixie asked Rainbow Dash as the harpy squawked into her face, hovering above her with the strong flaps of her wings.

“We’re magical, Trixie! Haven’t you been there the countless times we have to save this school?”

“Trixie… I didn’t know!” Trixie cried, closing her eyes. “I don’t know how we can fix this either!”

“Pinkie, I need you to calm down.” Starlight said slowly, holding her hands out as Pinkie giggled just as slow.

“I am calm, Starlight. Timmy has shared his slimy secrets with me.” Pinkie smiled and ran her hand down Starlight’s lab coat, leaving a trail of pink slime as the side of her pink face dripped with a similar ooze.

“Uh, Starlight, we might have a problem here.” Applejack said, lifting her skirt up slightly to show the toned legs of a brown racehorse. She neighed as she bent over the table, feeling a pressure in her backside.

“Uh oh, Pinkie! Something’s wrong with Applejack!” Starlight turned to see Pinkie stripping off her slime-stained clothes. “What are you doing?”

“My clothes are all dirty and slimy.” Pinkie said, starting to pick up the speed in her voice. A pink aura started to surround her as a puddle of pink slime appeared underneath her feet.

“What is going on here?!” Starlight shouted as Applejack whinnied, letting her equine backside form into a strong pair of hind hooves.

Fluttershy’s ears started to grow out as her skirt and panties ripped away, her shifting legs turning into a slimy coat under a layer of scales. She crossed her arms over her chest as a pair of auxiliary limbs started to form at her hips, letting her mind start to fade into her amphibious thoughts and urges.

“That’s… not a snake! Sunset sabotaged Trixie!” Trixie shouted, getting up from off the table as Rainbow Dash perched on the side of it, her bare feet having shredded her shoes and socks away. She softly preened at her wings before glaring at Trixie.

“Like snake Fluttershy would be any better?!” Rainbow Dash squawked, slowly making her way down the table, knocking over the science equipment.

“Si-ren?” Fluttershy held a hand to her forehead as she closed her eyes, hearing a siren’s song in her head. She started to softly vocalize as a thin pair of fins grew out of her back, her ears stretching out to fins as well. Opening her eyes, she slithered over to Trixie and smiled. “I don’t blame you. You clearly didn’t know how special we are.”

Trixie’s mouth fell open as she looked on the half-naked frog-like mermaid-siren. “I…”

“She’s finally at a loss for words, eh?” Rainbow Dash ran her wing under Trixie’s chin with a small smile, winking at Fluttershy.

The commotion at the other tables started to draw the attention of the crowd in front of Sunset’s table as Twilight began to hypothesize what was happening.

“With the girlsssss connectionsssss to my magical Element of Harmony, it’ssss highly likely that thessssse ssssscientific experimentssss we are conducting are transssssforming ussss into animal-like hybridssss.” Twilight hissed, sitting down at a chair as Rarity started sobbing in the corner.

“Well, that’s just fantastic,” Sunset said sarcastically. “You’re a smart girl Twilight, how do we stop these changes?”

“I don’t know!” Twilight shouted, groaning as the shoes and socks on her feet ripped away. “But I fear that I’m turning into a frog!”

“You sound more like a snake to me,” Sunset stated, noticing that Twilight’s legs started to merge together, covering in a pair of thick scales.

“Sssssnake?” Twilight asked, hissing with her thin tongue. “There wassss no ssssnake in the experiment!”

“Unless the test tube Trixie had…” Sunset thought back to when she bumped into the girl earlier, mixing up their unmarked test tubes.

“Unknown variablessss? Dear Celessssstia, thissss issss bad!” Twilight groaned as her skirt and panties ripped away, her lower half becoming a long snake-like tail. Sunset looked over at Rarity, who was gripping onto her hair.

“Rarity? Rarity, talk to me!” Sunset crouched down, hearing a soft chuckle from the bent-over girl.

“Spiders… the… spiders....” Rarity laughed under her breath. “They’re… in me…”

Sunset froze in horror as Rarity looked up with a crazed smile, holding a tapestry of spider silk in her hands that read “HELP ME.”

Applejack used her hooves to kick over the table, neighing loudly. “Whoa girl, you’re in my body and I’m not about to get expelled for hurting somebody!”

Starlight watched Applejack from the side of the table as Pinkie had already found Snips and Snails, making sure that Starlight’s project didn’t upstage Trixie. The two boys were motionless as the naked, slimy Pinkie PIe wrapped herself around them.

“Hey, boys~ You wanna have some slimy fun?” Pinkie asked, winking at them.

“Uhh… is she a slug?” Snails asked, holding onto Pinkie’s slimy arm.

“No doofus! She’s clearly a girl made of slime! Who would want to be a slug?” Snips shot back.

“I dunno. I like snails a lot.” Snails said happily as Pinkie kissed him on the cheek.

“Actually, I dunno if she’s so much a girl as…” Snips trailed off, seeing a long, slimy and dripping rod growing out between Pinkie’s legs. She blushed as she touched the tip, letting it bounce back and forth like a licorice stick.

“Whoa, nelly!” Snails said, his eyes opening wide.

“Yeah, we don’t swing that way, slimy!” Snips said, pulling Snails away and running far from the slimy girl.

“Aww… no fun.” Pinkie said dejected, her member drooping and dripping in front of her.

Twilight slithered back and forth, editing and checking her various pages of notes as Rarity continued to descend into madness, leaving Sunset more and more worried.

“Okay, even with the unknown variablessss and the added instance of the magic of the Elementssss of Harmony, thesssse transssssformationssss are relatively harmlessssss.” Twilight concluded.

“Relatively?” Sunset asked, watching as Rarity’s feet ripped away from her shoes and socks. “What’s the relative part about it?”

“Well, assss long assss we are ssssseparated, the effectssss of the Elementssss are only asssss strong assss the Elementssss in proximity with it. If we ssssstay apart, the effectssss may or may not lessssssen.”

“Okay, so you stay as far away from Rarity right now.” Sunset ordered as Rarity laughed, her legs deforming into eight, furred limbs, growing longer and taller.

“Yesssss… but…” Twilight moaned, feeling a pressure in front of her stomach. Sunset turned around to see Twilight sporting a thick, scaly member from her midsection as her tail slithered behind her. “There wassss a complication with intersssssex animal sssssamples.”

Rarity groaned and cackled as a large, furred abdomen grew from her backside, standing tall over Sunset and Twilight.

“Are you afraid of spiders, girls?” She asked, an eye twitching as her legs grabbed them by the lower half from behind the table.

“Starlight~” Pinkie sang, rubbing up against the girl in the lab coat with her dripping rod. Starlight looked behind her at Pinkie, noticing her new equipment.

“Oh no, this is not happening!” Starlight closed her eyes, feeling Pinkie pressing up against her clothes. Applejack whinnied as she trotted over, noticing Pinkie’s slimy member as well.

“Well, that’s unusual.” Applejack commented, flicking a blonde equine tail from her backside.

“Says the centauress,” Starlight added, keeping her eyes closed. Applejack moaned as she gasped and panted.

“I… wouldn’t be so sure about that.” Applejack blushed, feeling the long, thick equine member grow and hang from between her hind legs. Pinkie Pie squealed, her slimy member bouncing right up at the sight of Applejack’s rod. Starlight turned around and blushed at the girth of the equine shaft.

“Well, I think we all learned a valuable lesson here.”

Starlight, Trixie and Sunset backed into a corner at their respective tables, looking at the hybrid monsters that their efforts had created.

“Never mix magic with science.”

“Attention students! We have had our judges walking around the floor of the fair and we have decided on the finalists for the exhibition. Could we please have Starlight, Trixie, and Sunset bring their teams and projects to the stage?” The speaker announced from the side of the gym.

The girls worked on wrangling their half-human, half-animal teammates along with themselves to the stage. Twilight’s expression soured when she realized that having all of her magical friends this close together could accelerate their changes in appearance and even in personality.

“Oh my, it looks like we have some really good scientists this year.” Principal Celestia commented, writing down her notes on the clipboard for the girls' projects.

“I’m surprised to see that Trixie has such a magical project for once.” Vice-Principal Luna added, writing down notes as well.

“Well, naturally Trixie would succeed more than these two!” Trixie announced as Rainbow Dash squawked and flew behind her.

“Hey! I was on your side, Trixie!” Starlight shot back, not noticing the slimy Pinkie Pie creeping up behind her.

“SSSSSSunset? With all of the transssssformationsssss ssssso close together, I’m afraid of what might happen.” Twilight warned as Rarity grinned in her new spider form.

“Something like what?” Sunset asked right as Starlight shrieked. Looking over to the source of the scream, Sunset saw that the nude, slimy Pinkie had somehow managed to suck the lab coat and clothes right off of Starlight. Applejack neighed loudly as her equine shaft grew stiff at the sight of Starlight’s perky breasts.

“Like that.” Twilight said flatly as Trixie started to wave her arms to shoo Rainbow Dash as Fluttershy, in siren-mermaid form, slithered over to her.

“What’s the matter~? Don’t you want to win?~” Fluttershy said seductively, starting to pull down on her top to show off her chest.

“What has gotten into everyone?” Trixie asked as Rainbow Dash landed right next to her, pulling off Trixie’s lab coat with the talons on her wings. Fluttershy inched closer, grinning at Trixie with a sultry look.

“There has to be a way to reverse it!” Sunset shouted to Twilight before being lifted up in the air by Rarity’s two long, hairy spider legs. Twilight watched on, her own snake-like member starting to get excited from all the festivities.

“Go back? Why would I ever want to go back?” Rarity cackled, using her spider-abdomen to start wrapping Sunset’s arms together as she spread the scientist’s legs open. “Twilight, darling, don’t you want to feast?”

“Certainly~” Twilight replied, her tongue hissing as she made her way to Sunset. Twilight spat her hot venom, causing for Sunset’s lab coat and clothes to start to disintegrate off of her body, leaving the girl open and helpless.

“Twilight, Rarity, you have to fight this!” Sunset struggled as she felt Twilight’s scaly, snake-like body against hers.

“Mmm, such nice prey~” Rarity said, ripping away her shirt as she held Sunset captive against her bosom.

“Trixie does not appreciate being treated this way!” Trixie shouted as Rainbow Dash continued to rip and tear away at Trixie’s clothes while Fluttershy stared deep into her eyes.

“You need to relax and listen to me~” Fluttershy suggested, resting her hands on Trixie’s shoulders. Trixie’s eyes glazed over at the sound of Fluttershy’s allure as her soft opening grew wet with arousal.

“Trixie will do what she can for her…”

“Mistress.” Fluttershy finished, running her hands down Trixie’s stomach.

“Mistress.” Trixie repeated, falling on her back. Rainbow Dash shed off her own clothes as she crouched over Trixie’s face, her own slit in full view for the dazed girl. Trixie leaned up and started to suck on Rainbow Dash’s opening, slipping her tongue into her pink center. Rainbow Dash squawked loudly as she squeezed her breasts with her talons. Fluttershy smiled as she leaned down to Trixie’s moist slit, licking at it softly.

“I don’t think that can fit!” Starlight warned before having Pinkie’s dripping member shoved into her mouth. Pinkie giggled as Applejack slowly pushed her thick shaft into Starlight’s tight opening, Starlight spreading her legs as much as she could. Pushing deeper, she could only get about half of her length inside as Starlight moaned into Pinkie’s slimy rod, Pinkie thrusting into her mouth. Applejack started to rock back and forth into Starlight, currently on her hands and knees, being fully penetrated on both ends.

Rainbow Dash picked up Fluttershy’s flexible frog-mermaid tail and pulled off her stretched skirt. Fluttershy moaned in between Trixie’s legs, making the girl arch her back as the magician sucked on Rainbow Dash’s slit.

Twilight caught the tied-up Sunset in a kiss as she pushed her snake-member into her tight womanhood as Rarity held Sunset close to her bare breasts like a doll. She laughed as she made a thick, spider silk rope to gag Sunset’s mouth, muffling her shouts and moans.

Celestia and Luna watched on at the spectacle on the stage, which had devolved into an animalistic orgy of sounds and shrieks inching closer to their completion. With a heavy blush on her face, Celestia addressed the audience of the fair that had been watching this entire time.

“Due to the *ahem* animal nature of our three finalists, they have been disqualified from the science fair. The judges award the prize to the runner-up scientist with the potato-muffin battery!”

A small woo was heard from the crowd as the blonde-haired girl was awarded the blue ribbon.

“That’s it. Show’s over. You all can go home now.” Luna announced as the girls on the stage were still going at it. The audience had no intention to go as they continued watching and recording the events on the stage. “They’re not moving, sister.”

Celestia watched on as Starlight was double-teamed by the centauress Applejack and the slimy, slug-like Pinkie Pie. “Well, they have to stop some time…”

Luna looked over as well, sighing. “Why is this always happening?”
