Happy halloween and a great Nightmare night to everyone.

Sick chaos

(Some time after)

Rarity was awoken by water being thrown on her face

"agg coff coff" she looked down..and saw herself as her normal pony self "oh thanks Celestia!!!" she cried before rushing to a mirror to check herself. "I'm my beautiful self again!" Rarity exclaimed out with the widest grin possible along with tears of relief, "It was all just a horrible nightmare!"

"ummm should we..tell her?" asked Sweetie Belle at Twilight as both were standing behind Rarity

"Im tempted to say no but..." the Alicorn sighed; between the Spooky boutique and Carousel she came across the three fillies trying to carry the unconscious Rarity and decided to help them after they explained the whole thing "Ehem Rarity?!" she called for the unicorn attention.

!Huh? Oh twilight!" Rarity greeted her friend smiling "are you here to pick up your nightmare night costume?" she asked while fixing her hair because surely that dreadful business with that so called scary boutique had to be part of the nightmare.

"Actually...i was going to ask you how you feeling?" said the Alicorn "its there anything you want to tell me? any issue you want to get out?" she tried get her friend to talk

"Issues?" Rarity blinked giving her friend a confused look, "Whatever do you mean Twilight?" she asked with a forced little giggle, "After all other than a horrifying nightmare about a silly scary boutique of all things arriving in Ponyville with with the most ghastly disgusting unicorn i've ever seen I'm perfectly fine." she said to her friend who just gave a concerned look "Though, thank Celestia that was all just a horrible nightmare...and nothing that hideous could exist in real life."

Twilight flinched as Sweetie Belle hoof-palmed.

"Ok...she is all yours" said the filly before leaving.

"sigh..Rarity...that wasnt a dream" said Twilight making Rarity pause.

"I beg your pardon?"

"Scary boutique IS real" said the Alicorn "although..ghastly unicorn? oh! you must have meet Lydia´s friend" she said excited "I havent had time to go back as had plenty other scary incidents to check"

From a "carnivorous mailbox" to multiple monsters and scary incidents it seems someone or something was really trying to give everypony a hearth attack.

Although now it seems it was Rarity the one about to have one.

"Real....which means...all...that...really happen.." Rarity said her smile cracking and her expression freezing.

"Uh...Rarity?" Twilight looked worriedly at her friend who was lost in her own mind.

It really happen...that upstart business showed up brainwashing her customers...and that...that...FIEND...he...he...images of her turned into those hideous creatures rushed through her mind.

Her eye twitched again

"Rarity?" Twilight tried again.

"I...he...he..." she took a deep breath as her body turned red "IM GOING TO DESTROY HIM!!!!" she erupted in anger before rushing out her room.

"RARITY!!" Called Twilight in shock.

The white unicorn rushing down stairs, into the store and then out...

CRASH!!!

Where her race was stopped at crashing into a couple of ponies.

"Uggg" the trio groaned as Twilight teleported out.

"Oh Celestia! Rarity, Aloe, Lotus you ok?" she called at the three mares.

A heap of groans were only reply as she moved to help them

"Ugg..Oh Lotus, Aloe Im sorry" said Rarity "I promise you...for this I will give you a big discount on..."

Thats when she noticed the bags the spa ponies were carrying.

They all had the Spooky Boutique logo.

"You...you...bought from the scary boutique!" Rarity exclaimed out in horror...wasn't there anypony interested in her wares anymore!

Both ponies flinched

"Sorry Rarity" started Lotus

"we werent planning going there but.." continued Aloe

"we heard Fluttershy went there and actually bought something" said Lotus "a lot of things actually"

"and she hate Nightmare night" said Aloe in shocked tone.

"If someone was able to actually sell her something related to the festivity then it must have been really good" said Lotus

"And as such we had to check it" finished Aloe.

"And it turns out they've some really great creepy stuff of all kinds.." Lotus added in with a grin.

"We even picked up some perfect decorations for the spa.." Aloe chimed holding up her bag.

Although Rarity was about to explode again something about what they said echoed in her.

"wait...you went to...THAT STORE...only because Fluttershy went to it?" she asked

Both spa ponies exchanged looks.

"ehh yes?" Aloe answered.

Rarity´s eyes shinned,

"Idea!!!!" she called with a smile "ohhh thats perfect"

And without another word she trotted away.

"Uhhh...good seeing you.." Aloe said in a unsure tone while trading nervous looks with Lotus.

"Ugg Rarity wait!!" called Twilight rushing after her friend. Honestly she was starting to wish the others were here because she was starting to think she might need some help from stopping Rarity before she does anything she'll regret.

Not long after both ponies were racing to the outskirts of Ponyville towards their shy friend´s cottage

"Rarity!!! what are you even thinking?!" called Twilight.

"Easy darling, you heard Aloe and Lotus!" called Rarity back "if i can get Fluttershy to buy MY costumes in MY boutique then other ponies will get attracted to buy too!" she giggled "not only I will get my clients back but will be able to dress-up Fluttershy for Nightmare night!" she declared "double win!"

"Uh...Rarity i'm not sure that will work as well as you think." Twilight said nervously.

"And why not?" asked the unicorn stopping "I mean..if she bought something of that store then it shouldnt be difficult do the same for me that am her friend right?"

"Of course you are but.." Twilight started to say but Rarity wasn't really listening more focused on finding Fluttershy.

"then there shouldn´t be an issue help a friend!" declared the white unicorn as they reached the cottage.

"sigh..." Twilight sighed knowing there wasnt a way to talk her friend out of this "well...at least this gives me the opportunity to talk to discord and se if he knows anything about the pranks" she though with a tired look while Rarity moved to the door of the cottage knocking on it eagerly.

"Fluttershy darling! are you home!?"

The door opened...and there was Fluttershy...dressed in a white medical suit and face-mask? holding some jar of ointment?

"Oh..hello Rarity..Twilight" she greeted.

"Hey Fluttershy." the princess greeted her friend with a wave before arching a brow, "Uh are you going as a doctor for nightmare night?" she asked with a tilt of her head.

"ummm no...why you ask?" asked the pegasus

"well..." Twilight pointed at her outfit

"oh this? well..its only a precaution...umm Discord is...well..." Fluttershy fully opened the door showing her living room.

Were certain spirit of chaos was scratching like crazy; his body covered in a red rash and pustules.

"Uggg ahhhhhh Fluttershy!!!" he cried "you found that ointment?!!!" he asked as he summoned a rake to scratch his back.

"Ah yes..right here!" Fluttershy said quickly flying over to Discord while Rarity and Twilight looked at his state in shock.

"My goodness! Discord what's happen to you!?" Rarity called out in shock his state actually causing her to forget for at least a moment why she was here.

"Uggg thats what I want to know!!!" cried the spirit of chaos changing the rake for a cactus and scratching harder.

"He has been like this since yesterday" said Fluttershy moving to Discord side "it started small but then..." she pointed at the scratching Draconequus as she opened the jar and put some cream in her hoof before putting it over Discord´s skin.

While Rarity gave a concerned yet disgusted expression Twilight frowned remembering a particular incident.

"This isn't the trick you tried to pull on me and Cadence is it?" she asked sending him a accusing look "because with all the trouble I've been having to deal with i'm in no mood for your shenanigans Discord!"

"Trick?!!!" Discord called in shock/anger...before scratching more "I will let you know Twilight" scratch "this is no..." scratch more "trick!!!" and more scratch

"And you will make it worst if you dont stop and let me put the cream" called Fluttershy.

"Urrrgg but's so itchy and dry!" Discord whined out with a upset look but allowed Fluttershy to float closer, "And it's driving me insane!" He exclaimed out his head turning into a cuckoo clock.

"I had to put him in isolation" said Fluttershy to the others "he hasnt leave the cottage since yesterday morning"

"Are you sure?" Twilight asked with a frown because she knows with his abilities it wouldn't be too hard for Discord to sneak off and cause chaos, "because there's been trouble all over town and honestly it seems right up discord alley." she added with a frown.

That stopped Discord.

"Excuse me?" he asked..before scratching a bit more "what you mean" scratch "my alley?"

At that Twilight gave a frown before sighing and proceeding to explain all the chaos that had been happening lately around Ponyville

"Oh goodness..it seems someone really has taken Nightmare night pranks to the extreme" said Fluttershy as he applied cream on Discord´s back.

"uggg...seems so" scoffed Discord "and while i feel insulted you decided to blame me..." he said to Twilight "that actually could explain where this rash is coming from" he shivered as a hand detached to scratch his back...only for Fluttershy to slap it away.

"What do you mean darling?" Rarity asked speaking up with a frown.

"I mean there's a foreign source of chaos magic in Ponyville." Discord stated flattely with a slight scowl.

"What?!" Twilight shouted out while all three of the ponies gave him surprised looks, "But you're the only one who has or uses chaos magic!" Twilight exclaimed out before adding with a pause, "Well with the potential exception of Pinkie considering i've got my theories there.." she muttered out with a slight thoughtful expression.

"And umm...how could...another source of chaos magic cause this?" Fluttershy asked speaking up with a concerned yet confused expression.

"Uggg...have you heard that too much of one thing is bad?" he scoffed "well THIS is what happen when there are TOO MUCH chaotic energies in one place other than my own" said Discord "its the same magic but with different flavor..one it seems im a bit allergic too!" he explained..then began to scratch again.

"Hmm I see..." Twilight hummed out thoughtfully frowning, 'but that still leaves the question of who the other source of chaos magic belongs to?"

"Ugg I dont know..but i want them out!!!" yelled Discord "not only to stop this rash but also.." a flash and he was dressed as cowboy "this town is not big enough for two chaos users" he said in serious tone...before having to scratch his costume off as the rash returned.

"Umm actually darling I think I might know who the troublemaker is.." Rarity said speaking up as a slow smirk crossed her face her mind going back to that disgusting unicorn.

"You do?" Discord and Twilight asked..one with eagerness...the other with suspicious.

"Indeed darling and I believe this proves my suspicious about that so called scary boutique were right on the bit!" Rarity added sending Twilight a smug smirk before turning to Discord and explaining all about the so called rival business, how her customers were being brainwashed, and what happen with what had to be the most disgusting unicorn she'd ever met!

"In conclusion, its more than obvious this unicorn and that Lydia are responsibles for it and we need go close that shop down for good!!" declared the unicorn feeling proud of herself already imagining they closing that boutique and all ponies celebrating by buying her costumes.

"Uh..." Silence stood in the cottage for several moments before broken by Twilight, "Don't you think you're jumping to conclusions a bit here Rarity." Twilight said tentatively.

"What?!!!" exclaimed the unicorn "thats the most reasonable explication for all that have been happening!!!" she said feeling angry that her friend didnt share her opion.

"It just seems you're jumping to the first possible suspect here." Twilight said raising a placating hoof, "And.." the princess gave a grimace, "your opinion is admittedly a bit bias"

"BIAS!!!" Rarity exclaimed in shock "if anything Im being the only one reasonable!!! yelled the unicorn"Everything was just fine before that shop and those ruffians showed up!" she exclaimed giving Twilight a glare, "Or am I suppose to believe it's all just a misunderstanding or coincidence!?"

"Could be" said Twilight "but also is more than obvious you have something against the new boutique"

"Of course I do! They're brainwashing innocent ponies!" Rarity exclaimed out as if it was obvious.

"Just because ponies find her shop interesting is no reason to think she is brainwashing anyone!" called Twilight back.

"Please brainwashing is the only reason anypony would be interested in those abominations!" Rarity retorted back heatedly.

"Couldnt be she has talent and you, for some reason I cant fandom, are jealous?" Twilight said it directly.

"Why would I be jealous!? And are you implying that I don't have talent!?" Rarity demanded angrily.

Twilight also got angry.

"No one is saying that Rarity!!!" The Alicorn yelled "ever since that store opened you have been acting all weird!! jumping into conclusion and simply acting all hostile towards Lydia and anyone that buys from her!"

And as they were escalating into a argument Fluttershy and Discord stood off to the side awkwardly while temporarily forgotten.

"well excuse me if I dont like being simply set aside for some newbie second-hoof store!!" Rarity yelled back.

"Rarity they actually have good products and Lydia is a perfectly nice young mare!" Twilight retorted back.

!HOW CAN SHE BE A NICE MARE WHEN SHE HAS THAT..THAT THING AS COMPANION!!!" the unicorn yelled remembering her recent incident.

But Twilight was tired of this.

"Uggg forget it" she turned to Discord "I know you are like this but i need help to find this new chaos source, would you be able to move?"

"Urg...yes...but..arg.." Discord gave an annoyed scowl, "I might likely be off my game...so to speak." He admitted reluctantly while moving to scratch only for Fluttershy to smack his hand.

"Sigh I get it" sighed Twilight "well better some help that none" she said "once Fluttershy finish helping making you feel better, meet me at the market" she said before trotting to the door "And Rarity.." she gave her friend a frown over her shoulder "you need to calm down about all of this...just because you've got some competition in town doesn't mean it's the end of the world or that they're evil." she then added "In fact i think the only one hurting your business in this moment is you!"

At that Rarity gaped speechless at Twilight watching as her friend left out of the room.

In anger, the unicorn rushed after her

"You take that back Twilight Sparkle!!!" she yelled in anger but the Alicorn already was flying away "YOU CAN FORGET GETTING YOUR COSTUME FROM MY STORE YOU HEARD ME?!!" he yelled at her friends flying retreating form while Discord and Fluttershy exchange looks behind her.

"For once I actually feel awkwardly uncomfortable." Discord whisper out to his friend.

Fluttershy nodded...and slapped Discord hand from trying to scratch again.

"Grrrr..can you believe how stubborn she's being!?" Rarity exclaimed whirling around to face them with a dark scowl, "The culprit is staring right in her face and she refuses to see it!" she growled in anger "well Im going to prove it and I will get my clients back" she looked at Fluttershy "and you my dear, will help me do so"

"Uh me?" Fluttershy asked with a startled look point her hoof at herself, "Um...why? And ah...maybe we should...ah just decorate for nightmare night instead."

Discord snapped his fingers and the cottage interior was filled with fake bats streamers, jack-o-lanterns, and fake spiders

One of which descended to scratch his back.

"Discord...no.." Fluttershy said with a slight while flying up to grab at the spider.

"But it itches so bad!" The draconequus whined out.

"And i have still cream to apply" called the pegasus in motherly manner

"But itch!!!" he called managing to scratch a bit.

This caused some sparks that fell on a bat-streamer..causing the bats to actually come to life and began fluttering around.

"Oh dear....that can't be good.." Fluttershy muttered out watching as the bats few around the cottage while Rarity suddenly stiffen.

"Oh dear...Discord!! get rid of them!!" the unicorn called clearly uncomfortable and with some fear.

"Urg...what?" Discord asked with a confused blink while in the middle of attempting to scratch himself.

"The bats Discord...THE BATS!!" Rarity yelled as the flying creatures seems to take interest on her "AAAAAH! They're in my mane!" With her screeching out a moment later as a swarm of them swooped down with some of them entering her hair.

She immediately fled out the cottage rushing back the road to Ponyville with the swarm chasing after her.

"umm...goodbye?" said Fluttershy.

"well..that was a bit rude" said Discord trying to scratch.

Only for Fluttersy to slap his hand again.

With Discord giving off a disappointed whine at first before scowling.

"But regardless it seems I have a urg...a charlatan...urg...stepping on my turf...urg...who needs a lesson...and...can I please just scratch?!"

The pegasus gave him a flat tone.

"Get in the coach so i can apply the cream and no scratching" she said "later you can go help Twilight"

"Fiiiiiiinnnneeee..." Discord whined out drawing it out with a scowl...but not before Fluttershy once again slapped his hand down from an attempted scratch.

(Meanwhile with Rarity)

"Bats...bats..bats...I HATE BATS!"

The unicorn kept running with the cloud of bats following close.

She looked around and finally dived into a bush letting the flying beats fly pass her.

With a few moments passing by before Rarity tentatively poked her head out and let out a sigh as she saw the coast was clear.

"I'm beginning to despise this holiday." she muttered out with a scowl while hoping out of the bush. Her main and tail with leaves and branches stuck on them "REALLY despise it" she shook like a dog to get those out her hair.

In that moment she heard laughers close by. With Rarity at first giving off a blink before looking to the source of the laughter and what she saw caused her bad mood to only worsen.

It was Thunderlane and his little brother Rumble.

However now both had reptilian wings, tails, claws in their hooves, and horns on their heads.

Rumbler actually let sparks out his mouth.

"This is incredible!!!" the colt-turned-dragon called in excitement.

"Hehe I know" Thunderlane said laughing with his own wide smile "I wonder if this is what Spike feels like all the time?" He added with a thoughtful look to his now dragonic wings.

"Hahaha I dont know" Rumble called as he began flying "all I know its that im not taking off this costume ever!!!" he said in delight.

Rarity felt a vein twitching as she heard this....was there nopony left with sensible good tastes!?

"Hehehe get you little bro" said the older pegasus "that new store sure is something"

"We need to go back for the candies they sell too" proposed the colt.

"You know it!" Thunderlane agreed with a wide grin, "with the scary boutique, this is going to be the best nightmare night ponyville ever seen!"

Both siblings laugh flying away.

And leaving behind a steaming Rarity.

"Best Nightmare Night ever because of the Scary Boutique.." she repeated outrage while breathing deeply, "Well we'll just see about that!"

She had enough about the Scary Boutique!

This was a declaration of war!!!

One she plans to win.
