Wind was hustling through all of the ponies in Ponyville as they were minding their own business. There was birds chirping in nests on tree branches as they had hatched their eggs with Fluttershy sitting beside them, watching in awe. Everypony in Ponyville were having joyful smiles on their faces as they were trotting around town. It was not like this everyday, it felt like today was something special but couldn't put a hoof on it on what made it feel special. Lyra was exchanging a gift to her newly fiancée Bon Bon since they had recently proposed to each other a couple of months ago. Vinyl and Octavia had also seemed like they had tied the knot.

At Sweet Apple Acres, an orange farm pony was bucking apples off a tree and letting them drop inside a basket. She wiped a sweat from her brow after a long day of hard work. She glanced at Big Macintosh, who was sleeping whilst having his back leaned against a tree. There was a piece of wheat in his mouth. Applejack rolled her eyes and turned around towards her tree that she had recently finished bucking.

Applejack's ears twitched to the sound of giggles coming from the background. She glanced around, trying to detect the source of the weird noises. She scattered through the isle of trees, flinching as the giggles had gotten closer. The cowgirl grumbled as she continued trotting through the path.

Apples were rolling forward in front of her as if it was magic. Applejack raised an eyebrow in bewilderment as she ran after them. They were leading to a pond and noticed the cowgirl's own reflection. She looked at herself as to why they had led her to a pond that is so shiny. She noticed a speck of dust was stained on her freckles and her mane was frazzled due to all of the hard work she had been doing recently. If Rarity was here, she would given her a makeover as soon as possible.

The cowgirl was getting impatient to find out what the presence of the giggles was since it was getting louder and louder as she moved. She stood back up from her crouching position and started trotting through the nearer trees. She looked up at the sky to spot a familiar rainbow mane hanging down from a fluffy white cloud. She smirked as she also had spot a poofy pink mane hanging down from the leaves of the tree.

She got out a ladder from her hat and leaned it against the tree to climb up towards the bush of leaves. She didn't hesitate to pull the pink tail down. Although, she didn't think about the consequences of her doing that. She immediately dropped to the ground along with the mysterious pink tail. She was now seen laying on the ground with a pink pony sitting on top of her.

She growled under her breath as she pushed the pink pony off of her back. Applejack glared at her but stopped to realise that there was another pony as well. She motioned her hoof to her eyes to the pink pony's ones, making her gulp sheepishly. Applejack grabbed a lasso from her hat and twirled it around in the air to grasp onto the rainbow tail, that was hanging down from a fluffy white cloud. A blue pegasus was then dragged down to the ground, having the cowgirl spit out her rope from her mouth.

''Will ya care to explain why ya were making me mad?'' Applejack asserted, scowling at them.

''Relax, AJ!'' Rainbow affirmed. ''We were just kidding around with you. It was Pinkie's idea.''

Pinkie was just waving her hoof at the cowgirl with a big smile on her face. The cowgirl rolled her eyes in annoyance, stepping in front of them boldly. A draconequus teleported in front of them.

''Well,'' said Applejack, ignoring the draconequus, ''you could have pranked when I'm not doing my chores. Ever thought 'bout that?''

Rainbow huffed. ''You're no fun. Come on, Pinkie. Let's go prank some other ponies, background pony.''

The rainbow maned blue pegasus started trotting off as she led the pink earth pony with her as she wrapped a hoof around her neck. Applejack nodded in approval until a twinge snapped her out of it.

''Hey!'' she called. ''What did you just call me?''

Discord rolled his eyes and teleported himself beside the two ponies' side.

* * *

Pounding herself on her bed, was flowing outside from her nostrils as she had breathed heavily. The cowgirl turned herself around as she was thinking about some things to herself.

''I mean,'' the cowgirl said, ''she wasn't entirely wrong, though. Was she?''

She thought back to all of those times where she was seen as just a background pony. In her group, Twilight was the most prominent pony in the whole wide world of Equestria since she is a princess. It would also be about Rainbow and Pinkie too since they are the most charismatic in the group and Rarity has three boutiques that are famous in all of Equestria. Although, it wouldn't really be about her or Fluttershy. For Fluttershy it would make sense but for Applejack?

Applejack would blame herself for this though since she would always get upset or angry whenever somepony pulls off a prank on her just like what happened a few minutes ago. She would enjoy a good joke but if it's too chaotic like Discord then she would have to deny it.

She had nothing against him anymore, just sometimes he can be a bit unpredictable. She knew her friend Fluttershy trusts him and is now dating him so she didn't know what she was so worried about him. Snapping out of her trance, Applejack tapped her chin to ponder to herself until a lightbulb had materialized on top of her. A big sly grin started forming on her lips.

She stormed out of her bedroom door, having Apple Bloom blink in bewilderment as she just stepped out of her own bedroom. Applejack quickly descended her staircase as Granny Smith, Big Macintosh and Sugar Belle watched her exit out of the barn in a hurry.

''Now, what has gotten that pony so worked up lately?'' Granny Smith questioned, raising an eyebrow. She turned towards her grandson and his wife for an answer but they just shrugged in response.

Applejack was trotting through the streets of Ponyville to spot a familiar rainbow maned blue pegasus talking with another familiar pink earth pony. She approached them with a smirk.

''Oh.'' Rainbow grunted. ''Hey there, Applejack. What's up?''

''Nothin', just...do you want to play off some of yerr tricks you got on someponies?''

Pinkie gasped, looking at Rainbow with a similar look. They both squealed, mind blown.

''You mean...?'' Rainbow started to say.

''You want to go pranking with us?'' Pinkie completed with a joyful bounce.

Applejack nodded. ''Only if you allow me to--'' She was suddenly caught off as they both tackled her with a tight hug around her neck. She wheezed until they pulled away from her.

''Of course we will!'' they exclaimed in unison, having a grin spread across the cowgirl's lips.

* * *

Three ponies and a draconequus were bouncing away from Twilight's kingdom as they had wagons on their backs with lots of books inside of them. They were all laughing with other as they got further away.

Spike was watching the whole scene from the window as Twilight approached him with a smile. His eyes went wide until he dragged the curtains closed on top of the window, having the violet alicorn blink in confusion.

Pinkie giggled. ''That was so fun! We should prank some more! It's even more fun with Applejack and Discord in our pranking club now. Don't you think, Dashie?''

Rainbow snickered. ''Yeah, I guess. So what shall we do now?''

Pinkie stopped in her tracks to ponder to herself, having the others do the same. She yelped happily for a joyful bounce once she had figured out a prank idea.

''How about we make the whole ice-skating rink into a chocolate river?'' Pinkie suggested, looking at the draconequus who wore a sly grin on his face as he was playing around with pirate boat in a bottle.

''Or how about we make Rarity's mane into cloud?'' Rainbow recommended, snickering to herself.

''Me having to make myself into Rarity and admit her feelings to...Oh. Never mind,'' Discord blurted, chortling.

''Guys,'' Applejack spoke in a louder voice. ''I think I have the most genius prank idea ever!''

Rainbow and Pinkie looked at each other and then back at the cowgirl. Discord was just fiddling with his fingers.

* * *

Applejack was in the of Twilight's castle with Spike in front of her as he held up a quill and parchment. Rainbow, Pinkie and Discord were sitting above them on a bay window. There was a pile of multiple scrolls beside them as they all snickered to themselves, whereas Discord turned himself into a rattle snake.

''Okay. Spike, take a letter to Princess Celestia,'' Applejack ordered.

''Already got it covered,'' Spike declared.

Applejack gave a smile in approval and started to let out words flow from her mouth. What Spike wrote was:

Dear Princess Celestia,

I have learnt a really valuable lesson about friendship today. What I learnt was...I didn't learn anything! I was right all along. Sure, I could always count on my friends and have a little fun with them but the truth is, I learnt that already too.

Yours,
Applejack AND PINKIE! AND RAINBOW DASH! AND DISCORD, CHAOS RESIDENT!

Spike winced, quickly writing down all of their names before rolling the paper up in a tube and sending it out of the window, letting it evaporate into green flames.

''Now Spike,'' the cowgirl said, ''double that letter multiple times and send it to the princess.''

''Uhm...okay?''

* * *

As Celestia finished reading the words off the page, she lowered the paper and looked bluntly. Luna was beside her, snickering to herself. Celestia turned towards her with a death glare.

She got out a quill and parchment but got interrupted with so many scrolls falling on top of her, making Luna laugh even harder on her. Celestia got her head out of the pile, sending her a glare at her for the last time.

She had enough of this. She levitated the quill and parchment out of the pile and started words.

Dear Applejack, Pinkie Pie, Rainbow Dash, Discord and Spike,

As much as I love your silly little pranks, you should never EVER do it on a Princess of Equestria otherwise there would be very VERY serious consequences.

Now, I would have let you go but since this had happened so many times, I'm sending you all to Tartarus. Apart from Spike since he is a baby dragon and did nothing wrong. You incompetent fools tried to drag dear innocent Spikey-Wikey into whatever this bullshit was all about.

Yours,
Infuriated Princess Celestia (Ruler of Equestria)

Celestia nodded with a sly grin written on her lips and sent the scroll out of the window, having it dissolve into green flames. Luna turned to her sister in concern.

* * *

Pinkie, Rainbow, Applejack and Discord gasped in unison as they had read the letter.

''I can't go to Tartarus!'' Discord exclaimed. ''What will Fluttershy think of me now? And I have already spent all of my life in that uncomfortable stone prison. This was all you incompetent fools' fault!''

''What?'' Rainbow shouted, getting taken aback by this. ''Don't blame me! This was all Applejack's idea!''

Applejack sheepishly tittered as she shrunk down to the ground.

''This was soooooo fun, though!'' Pinkie whined.

Spike was about to protest further until his cheeks puffed up and spat out a scroll with green flames. Discord snatched the scroll from his hands and skimmed over the words on the page. Pinkie, Rainbow and Applejack were all peering over so they could take a look as well.

Dear Applejack, Pinkie Pie, Rainbow Dash, Discord and Spike,

I know it's not April Fools but Happy Jokes Day! Oh, I got you all so good! Now how can you top THAT?

Oh, I really am hilarious. Aren't I, Luna?

Pffft. Yeah, right.

Oh, come now. You are just jealous that you don't have a sense of humour like I, Princess Celestia, Ruler of all of Equestria.

And me?

What about you?

Aren't I a Ruler of Equestria too?

Heck no. I'm the only prominent alicorn here, not you. Not Cadence, not her daughter, not even Twilight Sparkle!

Okay then. You've chosen Nightmare Moon I'm guessing.

Uh...no, I didn't. Now go back to your nap, Princess Luna.

Call me queen.

But-

NOW!

Okay. Fine, Queen Luna.

That's better.

Yours,
Princess Celestia (the only prominent alicorn known in Equestria)

P.S. Don't tell Luna though or she will kill me and I mean really kill me.

Written, sealed, sent out of the window.

* * *

Discord had read out the letter for all of them and they all breathed a sigh of relief.

''Thank goodness,'' Rainbow affirmed.

''Yeah,'' said Pinkie. ''I would not like to go to Tartarus.''

''And we now have learnt that Princess Celestia has a sense of humour.''

Pinkie gasped. ''Rainbow, do you know what this calls for?''

''Letter time!'' they exclaimed in unison.

Spike facepalmed, getting out another piece of parchment as an from them and started jotting down words to whatever they were saying.

Dear Princess Celestia,

We have learnt a very valuable lesson today. It was about you having a sense of humour, duh!!!

Yours,
Pinkie and Rainbow

P.S. This is Applejack here again and let me tell you...I KNEW THAT ALL ALONG!!!

Celestia had lowered the letter in her hooves and facehoofed herself.
