Alright so while this is late, I decided to get on with it and post it anyway because A. I have not posted anything in a while. B. This is my first one-shot which I can improve from, and it won't make people wait a hundred chapters later to see the ending. And C. This is my first holiday related story but not really because this is late, and you do not take time off for the start of April.

But oh well. It's done. I won't take it down even though I know I could do better. Vivisong out!


"Hey Sugarcube" Tikki had her eyes snap open to see Plagg in front of her grinning ear to ear.

"Plagg?!" Tikki flew up high above him, eyes bulged out in surprise. Plagg was about to reply but Tikki clamped her tiny paw over his mouth and looked over to Marinette.

She was still asleep mumbling things in her dreams. Tikki then looked over at the clock which read 5 minutes till midnight.

She turned back to Plagg and slowly removed her paw while hissing "What in the guardian's name are you doing here in the middle of the night?!"

"Well technically midnight is in 4 minutes" Plagg commented before getting cut off by Tikki again.

"What's wrong? Is there a situation!? An akuma? Hawkmoth? Chat Noir in trouble? Is that why you're here or-" Now Tikki was cut off by Plagg's paw.

"Relax Sugarcube, no Hawkmoth troubles right now, and my kitten is just as knocked out as yours" he said, bobbing his head towards Marinette. "Just thought I'd remind you first of the greatest day these humans ever invented that's about to happen in 2 minutes!"

That's when Tikki decided to rip his paw off and bonk him on the head. "You came here just for that?!"

" 'That' is the day I get to prank anyone and everyone and can't even be blamed for it! Not just because no one knows we exist, but because it's the point of the day!" Plagg almost sang in excitement.

Tikki started rubbing out the sleep in her eyes, trying to figure out what had gotten Plagg rushing over and make a big deal of. Then it clicked. When she got it with a look of horror that made Plagg snicker, she rushed over to Marinette's calendar.

The days of March were all marked out to signify that March was over. "Please tell me you're not here to tell me tomorrow is April 1st"

"Actually, TODAY is April 1st" Plagg moved Tikki towards a clock which had just struck midnight. "Meaning it's officially APRIL FOOL'S DAY!" Plagg cheered loudly.

Tikki instinctively slapped her paw over Plagg's mouth again as Marinette shifted in her bed. She yawned before turning away. '

Tikki let out a breath while loosening her paw off of Plagg's mouth. The second she did that, Plagg zoomed away. But not before whispering, "Good Luck Sugarcube"

All Tikki could do was groan before zooming over to Marinette and flopping onto her pillow.

MORNING AT SCHOOL

"April Fools pranks has begun" Plagg snickered in Adrien's bag before taking a peek around his classroom.

"My first target" he zoomed in behind Lila's seat.

Lila was trying to listen to Mrs. Bustier instead of thinking of her next lie to tell when Plagg planned out his move.

He quickly zoomed back, behind Mrs. Bustier's desk and phased through one of the drawers to get a pin. He flew back to Lila and pinned the bow in her long hair onto the back of the chair.

He stared at his work with a sense of accomplishment for his first prank. "Quite classic I could say" he said quietly before frowning since no action would happen until Lila got up for the bell or a bathroom break.

Until he rushed back to Mrs. Bustier's desk to find more pins. He smirked when he stared at more possible targets in the classroom.

Before the bell could ring, he had pinned on Kim's hood, Max's pants at the ankles, Mylene's jacket, Ivan's shirt and Sabrina's skirt to their chairs. He also pinned Juleka and Rose's wrists together, Nathanial's papers to his wrist and Alix's backpack to hers.

For Chloe, Alya and Nino he decided to take it the extra mile with more pins. The other holders of the miraculous should have an extra surprise in his opinion.

Nino had seen some movement around his ankles while Alya and Chloe heard some snickering but was distracted by the lesson to pay any more attention. Marinette was too busy staring at Adrien as he tried to make a sketch of Ladybug.

Plagg had decided anyway to lay off Tikki's holder since she would probably kill him for it, and from what he heard; the girl was clumsy enough. And of course, he couldn't hurt his kitten.

He flew back into Adrien's bag right before the bell rang and watched the chaos unfold.

Lila was the first to shriek when she tried to stand and felt a sharp tup. Everyone turned their attention to her as she tilted her head far back to avoid pulling on her hair while combing her hands through it to figure out why she was suddenly stuck.

Rose immediately stood up to run towards her but felt an arm pull her back. Juleka had noticed the pin and stopped her just in time before it could rip her bracelet and her glove. Rose paused to try and pull out the pin while others weren't so lucky to have caught on.

Kim's hood had made a quiet sound of ripping while Max felt a tug at his ankles. While he was bending over to try and pull them out, Kim kept spinning like a dog trying to chase its tail, to check the rip in his hood.

Ivan was trying to first free Mylene before freeing himself, Nathaniel was picking up loose papers that had fallen after he moved his wrist and Alix yelled out a "I'M GONNA FIND WHOEVER DID THIS" as she tried to free her wrist from her heavy backpack.

Chloe was screaming at Sabrina since she couldn't move at all without risking any of her designer clothes to rip while Sabrina was pulling out her own pins. Alya couldn't care less about the small rip in her sleeves when she raised her arms to pull herself free while Marinette helped at the sight of her being stuck. Adrien was pulling out the poorly secured pin on Nino's cap while Nino himself worked on his sneakers.

Mrs. Bustier had rushed to help Lila first and succeeded in pulling out the pin her hair. Plagg, feeling a little extra decided to rush through the chaos and pulled out the pin that kept Mrs. Bustier's hair up before zooming into Adrien's bag.

Unfortunately for him, Adrien caught him flying into the opening in his bag while Mrs. Bustier realized her hair had come undone and tried to fix it as before.

"Who is responsible for this prank?" she called out to her students once they were all free and her hair was in place. "These pins all came from my desk

After a moment of silence, much to everyone's surprise, Marinette's hand flew up.

"Marinette, how could you?" Lila asked in fake distress. "I thought you were our friend! Pinning us to our seats like that could've hurt someone!" Lila tapped her chin before saying, "Though it does make sense. I noticed you weren't stuck like the rest of us. Of course, Adrien was too but I couldn't see him at all so I wouldn't know"

Marinette resisted the urge to roll her eyes as she replied, "While I do agree that someone could've been hurt, and that Adrien had probably not been the one to do it" She paused at his smile towards her. "I only raised my hand to say that none of us could do this." she replied calmly much to Lila's displeasure. "We were all staying in our seats during the entire lesson, and no one could've gotten close enough to Mrs. Bustier's desk without getting caught with the pins so none of us could have done it"

A glance at Lila's glare made her give into the temptation at a stab, "But, I have to say I'm a little offended that you would believe I could do such a thing" Marinette tried to sound hurt while she continued, "I was just about to offer to fix everyone's rips in their clothes, but I guess you wouldn't trust me with them since you think I'd pull something like this."

The class suddenly looked guilty since for a minute since most of them had thought Marinette would confess in doing "The Pin Prank"

Some had a clear conscience though, "I never doubted you for a second, girl" Alya threw an arm around Marinette. "In fact, I was about to whip out my phone so I could film you being a detective in solving the case" she announced much to Marinette's amusement before pointing at her sleeves. "You think you could fix these for me? Nora will have way too many questions"

Marinette gave a smile as she nodded. "Come to the bakery after school"

"Can you help me with my hood too Marinette?" Kim jumped in.

"And my skirt!" Sabrina added, showing off the rip.

"And please check on my hat dudette!" Nino waved his cap around. He knew the hole was tiny, but he wasn't leaving anything to chance when it came to his cap (or headphones).

Marinette faltered a tiny bit before showing determination in her smile. "Alright, whoever needs their clothes fixed by today, drop them off at the bakery or give them to me and Alya after school."

Once she was met with nods, she held out a hand towards Nino who immediately understood and dropped his hat in her hand. She gave the hat a look over, focusing on the small hole the pin had left.

"Your hat's fine Nino" the DJ breathed a sigh of relief, "The hole isn't big enough to fray anything and if you want, I can even make a pin for it" she smiled at him to which he returned.

"Thanks, dudette" Nino grinned.

"Ahem" Mrs. Bustier had been watching their discussion and smiled at Marinette for her helpfulness. "Everyone may gather their stuff and grab their lunch. I'll check security footage for any clue of who could've done this."

Everyone was satisfied by that and went to grab their things.

Later when they were leaving, Lila ran up to Marinette who was chatting with Nino. "I'm so sorry for accusing you like that. I can get carried away" she said in a sweet tone. "Do you think you can repair my bow for me?"

Marinette matched it with "Oh it's alright Lila, though I don't think I'll have time everyone's clothes by today and Jagged had asked me to make him a new jacket for his next album, so would you mind waiting for about the end of next week?"

Lila found that her smile was a bit harder to keep on as she replied, "Oh that's fine!" before stalking away.

"Ugh, you all would really trust your clothes with Marinette!?" Chloe sashayed towards Marinette. "My clothes may have a few seams loose, but I would only give them back to the designers to fix. Marinette working on these designer clothes would be ridiculous, utterly ridiculous!"

Marinette rolled her eyes before turning back to Nino, "You have any design ideas for your pin?"

Nino nodded with a grin, "Do you think you could make it look like a turtle shell?"


As the day continued, Marinette noticed more strange things happening throughout the day.

Rose had slipped when walking into the cafeteria and crashed into Juleka.

Kim and Max suddenly got dunked with water while they were inside.

One of Alix' wheels had mysteriously popped off her skate as she got up from lunch.

Even Marc experienced a prank when he found his pencil and some paper stuck to his hand.

"What's going on today!?" Marinette murmured to Tikki when she got the chance to sneak into the bathroom.

"Marc swears he never touched any glue today; Kim and Max have no idea who splashed some water and Alix had tightened her wheels this morning!? I'm starting to worry" She placed her hands above her head as if she expected something to fall on her.

"There's no sign in the security cameras?" Tikki asked while silently hoping for a different guess than the one she thought.

"Nothing according to Mrs. Bustier." Marinette reported. "Though, Rose and Alix did swear they saw some sort of black creature race around near them."

Tikki frowned at that, and Marinette noticed. "Tikki, do you know something?"

Tikki sighed but nodded, "Marinette, have you checked your calendar?"

Marinette sent her a questioning gaze but moved her head side to side to say 'no'. She then opened her phone to check the date.

"It's April 1st" Marinette read slowly.

"The day of pranks" Tikki confirmed, "It happens to be Plagg's favorite human day aside from Halloween and Friday the 13thc she muttered loud enough for Marinette to hear.

"Plagg?! Chat noir's kwami?! Here?!" Marinette sputtered in surprise before making a realization, "Does that mean... Chat Noir could be here too?! In my class?!"

Luckily, Tikki had always had the ability to remain calm in any situation. That includes when her chosen could have the chance of learning of Plagg's chosen identity before they were ready. So, she had thought ahead and gave a calm answer.

"Marinette, Plagg thinks of himself as his own free kwami. He knows who you are so he probably thought the best place to start off his pranks would be near you. Once Plagg had a goal, it would be impossible for even Chat noir to stop him"

Okay so it may have been a bit of a stretch. If anything, Plagg would have chosen to be as far away from Ladybug and Tikki as possible. He probably sticked with the class since it was convenient, and he was eager. But that was his mistake, and she had to fix it.

Marinette seemed to have bought it though. "Well, he has to stop. People could make the same assumption I did or even worse"

Tikki sighed but got back to the situation "You should talk to Chat noir. There's no way Plagg is going anywhere near me" she said sheepishly.

Marinette nodded in agreement and called out her transformation words.

Once she was Ladybug, she pulled out her yoyo and furiously typed to Chat Noir that they needed to talk at their usual spot before de-transforming.

Tikki flew into her purse and for the rest of the day, Marinette looked out of doors before going through, watching the sky for anything that could fall and stepped carefully so she wouldn't fall on anything. Alya was surprised that Marinette of all people was the most graceful when everyone around them had some sort of mess to clean up from tripping or knocking something over or having something spilled onto them.

Once school ended, Marinette met with Alya and fixed up a good half of her classmate's clothes before transforming and zipping away to meet Chat Noir.


Adrien Agreste had noticed all the strange happenings around and while he had already scolded Plagg he didn't stop.

A lot of people had tripped or spilled something near him, and he always had run to help them up or grab them a towel. Right after school he decided to clear his mind as Chat Noir.

"Sheesh kid, they're just pranks" Plagg shrugged.

Adrien gave him a look but relented and called out his transformation words. He checked his stick and noticed Ladybug leave a message.

He raced towards their meeting spot while taking a few flips just for fun. He saw Ladybug pacing around their designated rooftop and once she saw him, she waved but had a serious expression.

"So, Milady, what brought this urgent call?" Chat noir gave a silly bow before cutting to the chase.

Ladybug paused before answering, "It's April 1st" she replied bluntly, "You know what that means right?"

Chat Noir scratched his head, "Do you mean April Fools? I didn't think you kept track of that Milady" he gave a grin even as she rolled her eyes.

"Well, my kwami mentioned that yours apparently loves this holiday and she knows him for pranking anyone he can during it" Ladybug turned to him, "Did you happen to see him sneaking away or doing anything suspicious?"

Chat Noir's expression turned serious, "What makes you think it was him?"

"I overheard some students from Françoise Dupont Middle School say that a mysterious black creature was seen zooming around, that no one could see anything on the security cameras and that pranks have been pulled left and right." Ladybug explained before sighing at his expression, "I've met Plagg, Chaton. He means well but he can get carried away at having fun"

Chat sighed but nodded, "Alright I believe you Bugaboo. What should we do?" he crossed his arms and winked at his partner, "I'd lecture him, but he doesn't listen to me anyway"

Now Ladybug was grinning, "How about a prank of our own?" she chuckled at her partners astonished face.


Plagg zipped out his chosen's ring and started to stretch from being cramped up in the ring. "Well kid, I take it patrol went well since I barely feel drained. But I've still got some cheese to eat" He flew to grab his cheese from a cupboard and to his surprise he found none, "Hey kid, did you move my cheese? It shouldn't be put in your mini fridge, it's best at room temperature"

When he turned however, Adrien pulled off his ring with a smile and held his hand out to Plagg, "You know if you steal Tikki's cheese she won't be too happy with me" he chuckled much to Plagg's confusion.

"What's Tikki got to do with my cheese?" Plagg asked bewildered.

"Come on Plagg, Ladynoir is going to be wondering why you're taking so long" Tikki said right after flying in.

"Sugarcube!?" Plagg exclaimed before shaking his head, "Alright you're going to explain to me what's going on" he dragged Tikki back out the window.

"Plagg what's up with you? I know we had to switch owners for this mission, but I didn't you'd care so much about it" Tikki was going to continue but got cut off by Plagg who at this point, thought he was losing it.

"What are you talking about Sugarcube? That kid over there IS my owner!" Plagg pointed to Adrien who was watching them out his window confused.

"Plagg are you okay? That kid there is Misterbug remember? My owner?" Tikki repeated slowly much to Plagg's annoyance.

"Sugarcube I'm telling you! That kid is my owner! Yours is pigtails remember!?" he was almost shouting and flew higher and higher with each statement.

Tikki sighed while pulling Plagg down, "Plagg I know you love April Fools, but this prank is getting on my nerves. How about you go over to Ladynoir's? you'll see that nothing's been changed, and I can finally get my cheese" she said before zooming through the glass to Adrien's hand where he now held a slice of Camembert.

"MY Camembert" Plagg thought to himself, almost bewildered when Tikki looked happy to see it. He shook his head, "You know what Tikki? I WILL go over to Ladybug's place. She'll sort you out. I bet she's even confused to why you left in the first place" Plagg thought resolutely before zooming off.

Once Tikki noticed he was gone, she backed away from the piece of Camembert on Adrien's hand as fast as she could while Adrien let out a chuckle.


A little while later, he was in front of Marinette place and phased through her window.

"There you are Plagg!" Marinette smiled at him, "Your macarons are over there" she pointed before turning back to her sewing machine.

Plagg knew his jaw dropped. "Okay they must be pranking me. I know that before this patrol, I was Adrien's kwami. AND MY FAVORITE FOOD IS CHEESE!" he thought to himself before taking a bite of the macarons Marinette had pointed to and almost slapped himself when he thought they were amazing.

"NO, NO, NO. Her family's job are bakers. That why these tastes heavenly" He thought to himself before chucking the bitten macaron into her trash and pausing to think. "I've got it! Sugarcube must've knew I've been pulling pranks and decided to get back at me by using my kid and her chosen! Oh, I'll show her" he thought triumphantly before flying in front of Marinette.

"Marinette, don't you think we should start a patrol right now?" Plagg asked innocently.

"Plagg, we just got back from one. Aren't you tired?" Marinette didn't even look up.

He kept off his smirk. "Well, I just think that maybe we could do some extra sweeps around Paris. And maybe hit up that Ladyblogger to see if she's seen any akumas"

Marinette hummed, "Well what about Misterbug? He'll be confused to why we're out again on patrol"

Plagg froze for a second, "We shouldn't bother him if that's what you think!" he said, trying to keep his voice calm since he didn't want Tikki to come after them and ruin his plan of exposing their prank. "Besides, take this as one of your fun times as Ladynoir! If Misterbug see's us, then we'll tell him it's patrol. No harm in enjoying your powers"

Marinette smirked at that but relented. "Alright then if you're up for it" she got up and did some stretching. "Maybe we'll even give Alya an interview for her blog!"

Plagg now was silently cheering. "Yeah, you should do that. We can watch it after"

As she smiled, he smirked, "Now what Sugarcube? There's no way Ladybug's going to forget an interview with her best friend. In fact, if she does, it'll just be proof that this is a prank. The entirety of Paris can't actually think that this is normal" he thought while being pulled into the ring, not noticing the giggle Marinette was trying to keep in.


Plagg could not believe it. He replayed the video Ladynoir had taken with Alya on the Ladyblog outside the Lourve.

Except it had now been renamed to the, Ladynoir blog. Alya had seemed overall normally excited to see Ladynoir except she was videoing in with a crowd of people who were excited to see Ladynoir but weren't overall surprised.

Plagg had even checked past videos and record on the blog. All about Ladynoir. He searched online for the Ladyblog. Closest thing that came up was the Ladynoir blog. He searched up for Ladybug and Chat noir and was told that all news articles had either been fake, a time where they had to switch because of an incident or a publicity stunt by the heroes to throw off Hawkmoth.

"There's no way this could've been staged. It's all REAL" Plagg thought in disbelief while he stared up at the smiling Marinette.

"That was fun Plagg. We should do it again some time." She smiled which only caused Plagg to break.

He let out something like a screech before zooming out her window to try and take deep breaths. He floated in front of Adrien's window in disbelief and almost sadness.

Until Tikki tapped him from behind with a smile on her face. Maybe because of the fact he wasn't thinking rationally about the situation because of his disbelief that Adrien was not his kid, did he only have the ability to shriek.

"SUGAERCUBE! WHAT I'M ABOUT TO TELL YOU IS GOING TO BE CONFUSING BUT YOU HAVE GOT TO BELIVE ME WHEN I SAY THAT LADYNOIR AND MISTERBUG ARE NOT PARIS' HEROES. IT'S LADYBUG AND CHAT NOIR" he yelled hysterically.

"I know" was Tikki's answer but Plagg barely heard her.

"THAT ALYA GIRL RUNS A BLOG CALLED THE LADYOIR BLOG BUT IT'S ACTUALLY SUPPOSED TO BE THE LADYBOLG" he continued yelling.

"Yeah, knew that too" came Tikki's reply to which Plagg started to process more clearly.

"AND ADRIEN IS Actually my…kid?" Plagg faltered on his words at the end.

"Well of course he is. Did your cheese fumes made you lose your ability to think?" Tikki rolled her eyes.

"This was all a prank?" Plagg asked almost in bewilderment.

"Yes, yes it was" Tikki finally grinned.

After making their plan to make Plagg think that they had switched holders. Ladybug and Chat Noir raced off to put it into action.

Ladybug had found and talked to Alya about making him believe that she had always been Ladynoir and Alya had agreed, and they worked together to make her new blog look realistic.

Chat Noir had met up with a few fans to spread the word that Ladynoir would be doing a one-time appearance and encouraged them to meet her in front of the Lourve.

Before Tikki went over to Adrien's, Marinette had explained what she needed to do and how she needed to act.

And their prank had begun.

"What about the Ladyblog and the news articles?!" Plagg asked.

"Oh, the Ladyblog was tricky, but Alya had apparently been told that her blog had to be taken down due to unsafe reporting and that it had fake news on it. She had taken it down to figure out what was wrong, so it was honestly just good timing when we came to her" Tikki shrugged, "As for the news, I think we actually missed that part. Ladybug must've done a good job of convincing you" she snickered before leaving.

Adrien knocked on the glass with a smile causing Plagg to turn his head. While the next day he'd be bothering Tikki on how she actually got her revenge by pranking him. All he could do was think of his mistakes.

He believed for a second that his owner wasn't Adrien.

He believed every word told to him.

He didn't double check the facts.

"Happy April Fools Plagg!" Adrien smirked at him which was quite out of character for Adrien Agreste.

Plagg was a fool.

An April Fool.


Yeah, so while I really feel like I could do better since I was kind of rushing, my goal for this was to just have the idea set in place and do it. Finish it and post.

I'm terrible with these story deadlines which is why this is the first you'll see a holiday related story from me, but I had to start somewhere. Even though it's late. But now I have a story up for you guys to criticize and I hope to get advice and feedback.

This is more of a "why not" kind of story which I'll probably be making more of in the future. Stories like these are ideas I make to practice writing and just get some them out of my head. For now, though, vivisong out!
