Light Heart's prank.

FlashTruth, a crystal pony was sleeping soundly in his bedroom, not noticing the pony that was quietly sneaking into his room. A bright green glow of magic came over a few articles of clothing as they flew out of the room.

"Sorry Flash, but I figured I'd borrow these. I know you won't mind." Light Heart whispered gently as he walked out of the room with his prize. He had never had the chance to prank Flash before, and this was a perfect opportunity for him to show his skills. Light gently walked back through the vale that hung from the doorway as he picked up the articles of clothing that Flash often held close to him.

He chuckled as he placed the hat that was covered with pins on his head, seeing the horn that made the tip of his horn stick out like a sore thumb. "Oh yeah, that thing. It's a little small, but not bad." Light mused to himself as he looked at the jacket with no holes for his wings.

"Flash, didn't you know that one of your best friends was going to wear this?"Light giggled as he summoned his sewing kit, using a seam puller to open some holes for his wings before putting it on. "That's more like it. I like how breathable it is."

Light then turned his attention to the shades. "Now, I wonder why these are so tinted?" He asked himself as he tried to put them on, only to realize how snug they were on him. "Wow... this is wonky! Are these some kind of tinted glasses?" Light asked, wincing as he tried to pull them off, only for one of the pins to give out as the shades fell to the ground. Light looked shocked as he picked up the broken pieces. "Okay... that's on me. Keep calm. Big rule in pranking is that if you break it, you fix it." Light muttered softly to himself as he quickly teleported the shades to his little brother. "There, Fuze can fix it when he gets up. Now..."

Light froze in place as he saw the camera sitting on the table. "Oh... that's too perfect." Light said as he picked it up, looking impressed by the quality of it. "Flash, you have gone all out on this. Now, how to go about using this. I know that he uses those magic horseshoes, but shouldn't there be a thing for earth ponies to use these?" Light played with the buttons, accidentally putting the flash on before two rods shot out and connected behind Light’s neck. “Perfect!”

Light quickly ran over to a mirror, getting a good look of himself in Flash’s clothes. He gave a mischievous chuckle as he started trying to mimic Flash’s voice. “Hello, ladies. I’m FlashTruth. That’s one name. Not two. It’s a thing my people have. Are you all going anywhere? I like dating hot mares because I am a bad…”

“Light?” The lights turned on as Light turned around to see Flash standing at the doorway, looking like he was trying to wake up. “What are you doing here?”

Light stared at Flash nervously before giving a cheeky smile. “Your window was unlocked.”

“Window? Why the hey would you go through my… Why are you wearing my clothes?” Flash asked as he started to realize what Light was doing.

“Oh… I had nothing to wear.” Light said as he tried to keep from giggling.

“Light, you are the one who told me that ponies normally don’t wear clothes,” Flash said as he saw what Light did to his jacket. “What did you do with my clothes?!?”

“Hey, you know how you always dreamed of being an alicorn? Now you don’t have to worry about having this thing mended if it happens.” Light said as he started trying to fiddle with the camera.

“Light, why are you doing this?” Flash asked before he was nearly blinded by the flash of the camera.

“I just wanted a pic of you in a more natural position. Well, I think I will take a walk around the block. I’ll see you later.” Light said as he started to run away from Flash.

Flash’s eyes widened in horror as Light was running around in his favorite clothes, with a camera with his photo in it without them. The thing that Flash hated about his natural look was that he looked so bland and generic without them. Then there was the fact that those clothes had been with him for a long time, tied to many memories of his childhood..

A Light was running off with them.

Laughing!

Flash instantly took off after Light as they ran around the house. “Light! You know I don’t go anywhere without those! Give them back! This isn’t funny!!!” Flash pleaded as he ran after the giggling alicorn, now wishing that he had put on his magic horseshoes to be able to catch Light.

Light was having the time of his life, enjoying being able to prank Flash like this for the first time. “Awe, come on! We’re inside! I just wanted to try them on. I’ll give them back when I am done… in an hour or two…”

“LIGHT!!!” Flash yelled as they were running around the table like a couple of kids, switching directions in unison as Flash was trying to catch the giggling alicorn.

As the two grown-ups were acting like kids, Flash’s adopted daughters walked in, being awoken by the noise that the boys were making.

“Dad, what is going on?” ShyStone, the zebra asked as she was wiping her eyes, not having her glasses on.

Flash was trying to think of something to tell his daughter, cursing his curse that stopped him from telling any sort of lie. “Well, we have a thief in the house, stealing my iconic clothes that had the appearance of Light Heart.” He told his daughter as he glared at the prankster. “Can you please get your sister, so that we may cash this imposter, and get my close back, please?” He asked his daughters nicely.

“He’s lying! He’s a changeling imposture that kidnapped your dad, so I grabbed your dad’s clothes and tried to stop him! Help me tie him up and force-feed him ice cream until he tells us the truth!” Light said dramatically, trying to hide the grin from the kids.

ShyStone was looking at both of the grown-up stallions that were running around, and how the one that looked like her dad was having trouble walking around without the glasses on. “Fast, we have a problem.”

“Should we tie them both up and call for grandma?” FastFox, the buffalo asked her sister curiously as she stood next to her sister.

“Based on the way that this one is walking,” ShyStone said while pointing to the white one. “I can tell that it is our dad,"

“That’s not true! I’m Light Heart! I just blinded the changeling with the camera!” Light said as he took another photo of Flash.

“Mhm.,” Fast said to herself while nodding & thinking about that.

Flash winced in pain, not liking the bright lights. “I was sure that the camera was set on no flash.” He said with a hint of frustration in his voice.

“Flash would have known what was set on!” Light exclaimed as he pointed a hoof at him. “I can prove that it’s me! I was the pony who snuck those triple chocolate cupcakes to you behind Flash’s back.” Light said as he was starting to wonder how far he can push this prank before it goes too far.

“That was YOU?!?” Flash yelled at his friend. “My cousin gave me a full lecture about how disrespectful it was from me to spoil their dinner, especially with junk food, while she was preparing a healthy meal.”

“It was an hour after lunch! She needs to lighten up a bit.” Light said as he and Flash kept running around the table.

Before Light could run off, he was tackled to the ground by his friend’s daughters.

“Why did you betray me?” Light asked as he playfully tried to resist.

“We know that you are the imposter.” Shy told Light as she tried to hold his wings back.

“Ya, the real Light isn’t a thief, and was told the silver rules by his mommy.” Fast added.

“It’s called the golden rules.” Light explained to the little Buffalo before using his magic to lift the kids off of him. “And I’m not stealing them. If I was, I would have been out the door before Flash came out of his room. I’m merely pranking him.”

“W… what?!?” Fast asked as she was set down on the ground next to him as Light took off the hat.

“I figured that I’d pull a prank on your dad, namely since I am good at creative ones.” Light said with a chuckle. “So, I snuck in, took his clothes, tried them on, and waited for him to wake up so I could mess with him.” Light said as he used the camera to take a photo of himself. “I was not going to keep these. I was just playing with your dad. No hard feelings?” Light said as he took off the jacket and handed it to Flash. “And may I have copies of those photos?”

“You may not,” Flash said while feeling his way back into his orange cote, and trying to figure out what side was the front of his hat. “Can I please have my glasses back.” He asked, trying to calm himself down and ask his friend nicely, trying to accept Light’s playful intentions for this rude awakening.

“Oh… about that…” Light cringed as he looked at the kids. “Um… remember kids, if things go wrong and you didn’t plan it too, be willing to fix your mistakes…”

One of Flash’s eyes twitched a bit. “W.. what did you do?” He asked with an eerily calm voice.

“Um… nothing that can’t be fixed. I’ll just wake Fuze and have it back to you in a few hours. You’re off work today, right?” Light asked as he gave a rather nervous smile.

“W.. what happENED?” Flash asked, cracking at the end a bit.

“Hey, we are going to look back on today and laugh about this.” Light tried to assure him as he backed away nervously. “That, and the lenses are perfectly fine…”

“W… please explain yourSELF!” Flash asked angrily as he started walking towards Light.

“You know, Book used to wear glasses, and my little brother is a wiz with mechanical stuff. You’ll never notice any difference.” Light said as he was now making his way for the door. “You may also want to put some clothes on. You never know when somepony is going to walk in on you unexpectedly.”

Flash pulled on his jacket, making it onto a long trench coat. “I.. can’t see without THEM.” He told him while walking toward the Yellow blur in front of him.

“Oh… well… I’ll go get them back.” Light said as he quickly opened the door. “I’ll even ask about a second pair for emergencies.”

“You better!” Flash told his friend. “If not you’ll have to be my Seeing-Eye-"Dog”. Then again, would that be a Seeing-Eye-Light or a Seeing-Eye-Pony?” He pondered to himself.

“Let’s think about that later. Have a good morning, and I’ll see you all at lunch. Thank you all for not killing me! I hope we can do this again soon!” Light said as he ran out of the room and started flying back to Ponyville.

Fast turned to her father. “Should I chase after him?” She asked her father.

“No.. we’ll wait for his return,” Flash told his ambitious daughter while waving both of them to his side.

“Light was just playing around, right?” Shy asked nervously, afraid of Light and her dad fighting with each other.

“He’d better,” Flash told his patient daughter as he caressed the corner of her face. “But there are some things that should never be played with.” He said looking at her face, and even though he didn’t have his pair, he could see the lack of her thick glasses on her face. “Fast, may you please go and bring your sister to her bedside table where her glasses are?” He asked in a soft and gentle voice as he started thinking about Light’s prank.

He had to admit that Light got him good, and it sounded like he didn’t intend to break anything. It was most likely a little game that Light wanted to play for some laughs.

Well, every good game has at least two players.

Time to start playing.

FlashTruth's prank.

One week later.

Light was lucky that Fuze was able to fix the shades quickly for him, namely due to him being worried that Flash would not find the prank funny. He was rather surprised when he saw how calm Flash was when he came back to return them. Flash seemed to have accepted the joke rather well, in spite of him asking Light to never mess with his clothes ever again.

Well, there went Light’s plans of switching the lenses on his shades.

At least Flash accepted the joke in the spirit it was given. That was the one thing that Light was worried about when he started pushing Flash a little too far. The fact that they were able to laugh about it later was the most comforting thing for Light, even though he’d never get the photos he took.

So, life went on. Light still had his job in Ponyville and he needed to be able to work there at least some of the time. Even then, he needed his days to be alone and relax a little. So on this day Light decided to walk through one of the trails which he enjoyed for a little alone time. As he was taking in the scenery and the fresh air, Light noticed a loose piece of newspaper on the ground.

Light gave a soft groan as he picked it up. “For Celestia’s sake! Why do ponies have to litter on trails like these? It just ruins the…” Light’s voice trailed off as he started reading the paper and seeing what it was. His eyes widened as he saw a photo of FlashTruth and a mare Light knew as Dandelion.

Breaking News
FlashTruth has finally confessed his love to the love of his life, Dandelion !
They plan to get Married in a Month ...

Light’s heart dropped as he saw this paper, namely due to having met Dandelion before. She was a pegacorn, which can be called a fake alicorn due to them having been born with unicorn and pegasus traits. They are rare, but Dandelion considers this to be an actual alicorn. She sees others as insignificant servants to her and tends to be a selfish brat. Light met her once, and she tried to force him to marry her. She is one of the few ponies that Light hates.

And now Light’s best friend was MARRYING HER!!!

Light’s body started to tense up as he nearly hurled at the thought of marrying a mare like her. “FLASH!!! NOOOOO!!! WHY WOULD YOU DO THIS TO YOURSELF?!? YOU POOR FOOL!!!” Light started to scream out as he was losing his mind over this article. He spent the next several minutes just trying to react to this.

After Light was done yelling, screaming, and crying, all while curled up in a ball, he finally got up with determination in his voice. “I have to stop this!” He declared before flying off to where Flash was staying. He knew it was a long shot for Flash to be in town, but it was the only place Light could think of that he’d be outside of MoonRacer.

Light burst into Flash’s “holiday home” without even thinking of knocking, calling out as he hoped his friend was in there. “FLASH!!! SPEAK TO ME!!! WHERE ARE YOU?”

Fast jumped up, almost knocking the board game board. “W..What?” She asked, running around in zig-zags toward the panicking Light Heart.

“Where is your dad? I need to talk to him now before he makes the biggest mistake of his life!” Light exclaimed as he was frantically searching the house.

Fast pointed to the board game that was set up in the middle of the room.

Light gasped as he saw Flash curled up, and snuggling with that manipulative jerk Dandelion, her wing draped over his body, while they were playing a game with his two daughters.

“Flash, no!!!” Light squealed out as he looked shocked by the sight.

“Oh, hey Light, I take it that you have heard the good news,” Flash asked his best friend before kissing Dandelion’s cheek, making her blush a giggle.

“Are you kidding me?!? When did that happen?” Light asked, trying to be somewhat reasonable about this, even though he looked like he was losing his mind.

“Well.. the first time my eyes gazed upon her, I knew and could feel that... We had a kinship between both of us.” Flash explained before kissing her forehead, right under her horn.

“A kinship? Did she have a heart transplant or something?” Light asked, looking as bad as Twilight did when Trixie and Starlight became friends.

“Oh Light..” The undeniable voice of Dandelion said. “You’re a nice pony, you are, but Flash has something that is a certain... Je ne sais quoi!?” She said before locking lips with Flash, causing Light to gag as he thought about the things she tried doing to him.

“You kidnapped me to try to make me your unwilling husband. Forgive me if I have no trust in you.” Light said bluntly.

“Yes… that is true, but now I can be the mother of those two little cute girls.” She told the baffled toymaker, before lifting her wings up and beckoning Flash’s daughters to her.

“You told me that it was what servants were for as you tried tightening my knots.” Light added, starting to get suspicious.

The little ones went to Dandelion, and sat next to her and started to hug her. “We know you’ll be a great wife to our dad.” They told her. “We love you, Mom!”

Light was in shock as he saw this. There was no warning that Dandelion would have done this with Flash… unless… she was out of character in several ways… so maybe…

“So… The whole thing about dragging me into a warehouse and trying to seduce me is just behind us now, even after I punched you?” Light asked Dandelion, noticing a small twitch in Flash’s eye before the mare spoke. Light knew that this was a cue that his truth sense went off.

“Well Light, you should learn to…” Dandelion was about to say more, but she was interrupted by Flash.

“Light, I would think that you would have been happy for me,” Flash told him. “I AM getting married after all!” He said while getting up, allowing Dandelion’s wing to flop off of his back.

“She tried to take my virginity. She is wanted. Maybe we should try to sort this out before Book gets to see her again.” Light added, knowing that this was something that Flash would know is true. “You remember when Book last saw you, right?”

“Yes, he really has a…” Once again his future wife was stopped by Flash, who was now worried that Light was starting to catch on.

“I can’t believe you, can’t you forgive her?” Flash asked Light.

“That’s for the law to decide. You know how Book is, don’t you, Flash? I am your friend, and I just want you to be safe, and not worry about any legal ramifications. We should take this to Book and sweep this under the rug before anything happens. After all, you aren’t scared of Dandelion going to Book, or the main six, right?” Light as he had a small grin on his face.

“Oh.. I don’t,” Flash said with confidence, before hugging Danelion’s head.

“Good, because Book has this wonderful process for dealing with changelings now, but she shouldn’t have to worry about it.” Light said as he started walking out of the room.

“What does that have to do with my Lovely wife?” Flash asked with a small hint of concern.

“Well, you know how paranoid Book gets when some pony has some unexpected character changes. But don’t worry. It’s harmless to ponies, although some of his prototypes have had some side effects.” Light said, keeping his back to him.

“What are you implying?” Flash asked, knowing that Light was telling the truth. Book was the guardian of Ponyville and was known for being tough on crime. “What are you accusing?”

“Nothing! She’s not a changeling. She’ll take a whiff of the gas and feel nothing. It’s not my rules. It’s just what Book would do. Can you tell me that he wouldn’t be suspicious of this change of heart?” Light asked as he kept walking.

“Well, maybe she saw the light, not you, and wants to redeem herself,” Fast said while hugging Dandelion’s leg.

“Yes, but Starlight had to go through the same test when she became Twilight’s pupil. Just relax. It’s not like you are dating an ex-changeling queen, right?” Light asked as he neared the door.

“What about halflings?” Shy asked, while gingerly making her way to Light.

“She’s a pegacorn. He only tests those whom he has reason to suspect.” Light explained as he turned around. “Look, if you really love her, I’ll forgive her, but Book’s tolerance for forgiveness is lower than mine. Just relax. I don’t see any reason for her to be afraid.” Light said as he looked at Flash. “Right?”

“Oh.. didn’t you know..” Flash tried to ask. “She’s.. at least..., ⅛ from.. both of her parents' side.” Flash stuttered out.

“Really? Book’s records don’t show that. Are you sure it’s Dandelion who has that?” Light asked as he walked straight up to Flash and whispered to him. “If you are hypnotized, nod, and I will punch Cryssy so hard that she won’t be running away this time.”

Flash's eyes widened in horror at the theory that Light seemed to be forming. He knew instantly that this prank needed to be stopped. “Ok, this had gone too far, Light,” Flash said before lowering his head down to look at Light.

“Agreed, so tell Honest to drop the act.” Light said with a small smile as he started chuckling at the prankster.

Dandelion huffed before bursting into soft green flames, leaving behind a changeling with a hair-bun and small spectacles on her nose. “How long?” She asked curiously as she looked disappointed in herself.

“I started to suspect that you weren’t Dandelion when Flash went on the defensive. When you stayed silent for several questions, I figured it was most likely that it was you and not the ex-queen.” Light explained as he sat down. “Although you two nearly gave me a heart attack after seeing that paper. I’m guessing one of you planted it?” Light asked Flash as he was catching his breath.

“Yes, it was I!” Flash admitted with a hint of pride. “I was hiding in one of the trees, waiting for you, using my pointing spell to make you notice the piece of paper.” He said before laughing. “You didn’t even stop to notice that the newspaper was dated for tomorrow.”

Light chuckled at his mistakes as he realized how clever Flash really was. “Well, I guess that no pony would look for an earth pony in a tree.” Light admitted as he petted Flash’s back. “And I need to understand what that spell was, but even then, that was a solid prank. One day you may even be able to give Dash a run for her money.”

“Oh, it’s an easy spell.” Flash started to explain. “I just find something that I want somepony to notice, choose who I want to notice, and then poof! It’s like somepony is in front of you, pointing at the paper, telling you to look at it, but since you’re alone your mind just presumes that you just happen to notice this.”

“Okay, so how did you get back before me? Did you leave before I started having a mental breakdown?” Light asked with a small grin.

“Oh, I managed to get back here before you, by just setting up a set of teleporters before,” Flash explained to his laughing friend.

“Wow, you almost pulled the perfect prank.” Light said as he looked at Flash with a sigh. “I mean, you have a lot to work on, but not bad.”

“I even was planning to set up a fake wedding. I was going to have my daughters be the flower girls and you as my best-stallion. It was going to be perfect.” Flash said with a bit of regret.

“Yeah, but your controlling nature was your downfall once I started going off of your plans. I also think you weren’t prepared for how bad of an impression Dandelion left on me.” Light pointed out as he petted Flash’s back. “That’s the problem when you get too complicated with a prank. Something is bound to fall out of place.”

“Ya…” Flash said before flopping down on the ground.

Flash’s daughter went to their father’s side and hugged him. “Does that mean we’re only going to have 2 mommies?” They asked him kiddingly.

Flash was about to smile before Light spoke up.

“Wait, you didn’t tell them?” Light asked with a disappointed tone in his voice. “That Honest was impersonating a kidnapper?”

“Well, I did explain the prank to them, and that Dandelion was a fan-girl with a “crush” on you, but not those two things,” Flash told Light before petting his daughters.

“So, that was a decent retaliation to my prank.” Light admitted as he looked at Honest. “Although I think I had the better one.”

“No ha!” Fast said. “Our dad’s was the better one.”

“And he didn’t have to break the law to do that.” Honest said.

“I didn’t steal, and it’s not breaking and entering if the king gives you the spare keys to the house.” Light pointed out as he looked at Flash. “And I kept the prank pointed at you and didn’t risk Honest’s health over somepony who didn’t know about the prank finding out. I was right about Book checking her, and you should have known that. You need to cover your bases if something goes wrong.” Light pointed out firmly. “Mine was the better prank! It had less risk and was easily fixable. Yours was overcomplicated while mine was easy and simplistic.”

“No, his prank was,” Fast said.

“Well, Light does have a point, and he did catch more ponies in it.” Shy pointed out. “And there was a good reaction from our dad.”

“But Dad’s prank lasted longer!” Fast started arguing with her sister.

“And didn’t work according to plan.” Shy reminded her.

“Girls, please don’t fight,” Flash begged his daughters.

“Yeah, we can take this to Dash. She knows that I am a pro at pranking, unlike you.” Light said smugly to Flash.

As they all started arguing with each other, Pinkie Pie bounced out of a plot hole. “Both of those pranks were very good. But how about we asked the fans which one they liked the most?” She said before turning to you. “What do you think? Which prank was the better one? Comment down below and check out the poll that they will leave in the link!”

“Um, where did she come from?” Flash asked in shock. “I thought that I put the teleporter away.” He said while making sure that it was in his pocket.

“Flash, what did I teach you all?” Light asked bluntly to the whole group.

“Never question Pinkie Pie.” They all answered at once.

“And don’t you forget it!” Pinkie said as she pulled a tray of cupcakes out of her mane. “Now, who wants a triple chocolate cupcake?”

“Meee!” Flash’s daughters squealed, before running to Pinkie.

“Always.” Light nodded as he walked towards the element of laughter.

“My cousin is going to yell at me,” Flash said to himself. “But... OK!” He said eagerly before getting his own.

“And thus the little battle ends on a good note.” Pinkie said as she handed one to Honest before turning to you one more time. “Goodnight everybody!”
