A/N: You thought that it was over? Well, there's still one more thing.
Meanwhile, at the exit of Doofenshmirtz Evil Inc, The ponies exited the building and went to find everypony from Ponyville, it was quite a night for them, but at least everything went back to normal as they saw the morning on the city.
They looked all around the city, streets, alleyways, buildings, everywhere, and nothing, they were getting quite tired, not only for the walk around, but all for the night they went though.
"Man, I'm quite tired of searching for every pony, where they could be?" asked Rainbow Dash tired.
"Ah don't know, but whatever they are, I hope they're okay and finally turn back to normal." said Applejack also tired.
Just then, they saw from where they were a herd of ponies in the middle of a street, they went closer to them and and found everypony standing there in confusion.
"Girls?" asked Twilight as she and the other Ponies asked confused.
"Dashie?" asked Pinkie Pie worried, hoping that Dash isn't angry at her.
"Yes, it's us." said Rarity.
"We've been searchin' for y'all everywhere!" said Applejack tired.
"We're just glad you guys are here with correct minds." said Starlight.
"You mean, we were really infected? Does the cookies Dashie just put were really infected?" asked Fluttershy worried.
"Yes and no, but you'll soon get it when I explain everything." said Starlight, causing every pony confused.
Twilight later realizes that they weren't the only ones, she also noticed something different on Rainbow Dash. "Derpy?"
"Hi." said Derpy as she waved.
"TRIXIE!!!???" asked Twilight angrilly.
"Oh, uh, hello, Sparkle. hehe..." said TRIXIE quite suprised at her nemesis' reaction.
"What are you doing here? And, why is Dash's mouth...rainbowfied?" asked Twilight confused and angry at the same time, knowing that Pinkie's plan didn't came out as Twilight wanted.
"Yeah, and what it this place we were at? It looks like a city." asked Spike upset and confused.
"I know you all have a lot of questions, but let me explain it all." said Starlight as she takes a deep breath and exalates. "So, after I leaved sugar cube corner after trying to confort Pinkie of the zombie prank you all were gonna give to Rainbow Dash."
"Wait, you knew about this?" asked Fluttershy shocked.
"Not until Pinkie Pie told me about the prank." said Starlight, causing every pony to look at Pinkie Pie with angriness, not only for the confrontation, but also that Starlight might probably tell Rainbow Dash about the prank right before all this happened.
"What? I just told Starlight that Dashie needed to learn a lesson about pranking, that's all." defended Pinkie Pie.
"But you were missing a point there, Pinkie, will you just stand there and let me tell my explanation, you'll soon get it." said Starlight, causing Pinkie Pie stood and listen to the rest. "Anyways, After I left Sugar Cube Corner, I saw everypony practicing for the prank to scare Rainbow Dash, I was quite upset about it, but the next day, the day of cookie sells, when I walked where Twilight and Spike was, I saw them being surrounded by something that humans call it, static."
"WHAT!!!???" yelled every pony in shock, knowing that how it could be posible that they didn't even noticed that.
"So with no other choice, I had to teleport to Trixie's house and tell her about the situation, and she said that she also saw other ponies being surrounded by static, and knew a pony that had never got the cookies for the same reason of my upsetness, and that was Derpy." continued Starlight.
"I told you guys, the prank you guys were gonna pull would end bad, and it's wrong." objeted Derpy angrilly.
"And we also saw everypony fainted to the ground when we entered their houses," said Starlight. "the night arrived and we saw Rainbow Dash heading to a portal that were a few inches from Carrousel Boutique, and saw Rarity, Applejack and the CMC's too distracted, so we went into the portal and lead us to this city called: Danville. It was right after you guys were with non-correct minds and entered before me, Trixie and Derpy entered."
Everypony was shocked with no words at Starlight's explication, they admit that they want to scare Rainbow Dash, but they never expected the way that it would all end wrong from the beginning.
"And we saw all of you with mindless minds, biting and scaring humans of this city instead, luckily Derpy found and had a box of joke cookies that was not infected by static, and took a bite and her mouth got rainbowfied, and as for me, well, I saw and read one of Twilight's books and used the spell that Twilight casted for everypony to make their colors dulled to Derpy, and made her mane wrinkled too, like Rarity showed us how" said Starlight, causing the confusion of Twilight and Rarity.
"But three questions, why is that so called 'static' surrounding the boxes? And how didn't we noticed them until now? And we did it came from?" asked Twilight.
"I'm getting to that part, Twilight." exclam Starlight. "After that, we hide into an alleyway and found Rainbow Dash. So we did the same to her in being like Derpy, the clues I've got where pointing to a certain building called Doofenshmirtz Evil Inc, and we went there and found a man with a lab coat, and explain us that the static came from a beam from his machine called I don't know, something 'Inator'."
"Repulse-inator." reminded Trixie.
"Yeah, Repulse-Inator," said Starlight. "and said that he build it to zap his brother, he's mayor of this city, and a portal that looked like the same portal we entered, opened and headed towards Ponyville instead, and I think it might have zapped the boxes of joke cookies instead, and if I would make an scientific guess, I say that the spell had combined the machine's effects right when you all took a bite out of one cookie."
Everypony with no answer, just hearing what Starlight was saying, it was quite impacting for them, but some of them wanna know how those two portals, Starlight just mentioned did opened from Equestria to Danville.
"We kinda got bothered with him for that, but he said that it was an accident, and he never planned this in the first place, he also said that he knew someone that might help us, and bought an agent platypus named: Perry the Platypus, but although, there was an only time that we saved him, but at the rest he helped us going to Doofenshmirtz Evil Inc." said Starlight. "We found a group of children, followed by two teenage girls, one with orange hair, and the other that was the daughter of the scientist we found, and also, Applejack, Rarity and the CMC's followed them, we found ourself, I told that wrongs never make it right as they confessed that it was supposed to be a prank to scare Rainbow Dash, which she obviously got angry about it, but later we leave that behind and continued on to turn you all back to normal, Rarity had a bottle of cure made by Zecora that can reverse magic effects and mix it with a big pile of water from a water tower humans just build, since we found out that water can neutralize static, and put a vortex sprayer to spray the whole city with cure and water and now we're all back to normal. That's all."
Everypony we surprised about the story Starlight just told, but later, Applejack stand and later started to explain another thing. "And honestly, we first thought that Pinkie's idea to flip the tables on Rainbow Dash seem like a good idea to make Dash to stop pranking for a while, but later by far we went on investigating on the prank goin' wrong, we knew that it would be no good to do that kind of prank to Dash if it actually happened."
"Yeah, it was quite odd to know that, and it will be by what I'm gonna say, but I think this chaos also made us learn a lesson we should all learn, and that is, never try to do things that seem right, because later it will possibly end wrong despite our feelings and intentions, no matter if their low or high." said Rarity determintly.
Everypony that was part of the prank put ashamed faces, they knew that Applejack and Rarity was right, their upsetness was so upset that their hearts never told them that it was wrong what they were doing, and it won't end up good for them if it really actually happen, they don't imagine how Rainbow Dash will feel after that such prank they were gonna pull to her, yes they also know that she prank them too, but making her think that she killed them was gonna be too much for her.
"And by the way, Rainbow Dash also wants to say something about the situation." said Starlight, causing Dash flying towards every pony.
"Guys, whatever you guys were gonna do to 'flip the tables on me' it wasn't no good, but no matter what, I'm just gonna say, I'm sorry, I'm sorry for the pranks that I pulled on you guys, I was going crazy on them that I didn't knew I was going to far." apologized Rainbow Dash.
"I'm glad you learned your lesson." said Fluttershy.
"Yeah." said Twilight. "And we're sorry that we wanted to teach you a lesson in a harmful way, our upsetness was so big that we didn't thought that we were gonna pay a price that we had to pay for the rest of out lifes if this prank happened."
"But we did it because pranks would be so much fun to enjoy, just not try to go far on them, like us for example. I wasn't with them at first, but there was no choice." said Pinkie Pie sadly.
"Can you at least come back to Ponyville? Everythin' won't make sense without you." said Apple Bloom.
"If you do, than will be happy, but if you don't, we'll understand, we respect your decision. You're not forced." said Twilight.
"Are you kidding?" asked Rainbow Dash. "Of course I'll come back, nothing on Ponyville will make sense if I'm gone."
"YAY!!!" yelled Pinkie Pie joyfully she jumped happy. "I can make a 'Rainbow Dash came back' party to celebrate our-"
"Pinkie! Maybe later, for now, I'm exhausted, in fact, everypony is exhausted too." interrupted Rainbow Dash as Pinkie Pie saw everypony tired.
"Uppsy, sorry, my bad." said Pinkie Pie as she return back to the ground.
"But there's something I don't get," said Twilight confused. "how did those portals Starlight mentioned opened?"
"I think I have something to do with that." said a familiar voice and when it popped to reveal itself, the ponies were shocked when they saw on pony else but...
"DISCORD!!!???" shout Everypony in shock and anger.
"Discord, what did you do this time?" asked Fluttershy upsetly.
"Oh Fluttershy," said Discord smugly. "I overheard Pinkie's plan to prank Rainbow Dash, I knew that something wrong was gonna go...wrong, so I used some power from a machine that a scientist Starlight mentioned called: Other Dimension-inator, by manipulating the power and mix it with the magic of the mirror portal Twilight used to go to Sunset's world."
"Wait, you were overhearing my story?" said Starlight angrilly.
"And how did you know about the mirror portal?" asked Twilight angrilly too.
"Oh, Twilight, I know a lot of things, and I also went to other worlds too," answered Discord. "even though my chaos magic can't be used for too long."
"WHAT!!!???" shout Everypony in shock.
"It's true, once we tried to use magic, but it didn't last for too long." exclam Rarity.
"Yeah, indeed, magic doesn't exist here, so we can"t use ir for long." said Starlight.
"Anyways," continued Discord. "I saw the scientist's machine called: 'Repulse-Inator' launching a beam, and the moment it launched, I opened a portal to Ponyville, where the carriage of joke cookies were at, causing the beam to zapped the pille of boxes, later when I saw everypony turned into 'Mindless Repulsive Cookie-Craving Zombie Ponies' I opened another portal where Dash went to and she also guide all of you ponies to here and, you now know the rest."
"Look Discord, I understand that you were trying to wake us up, and I apreciate that, but why did you do it, I mean, we could gave Dashie a lesson, but you had to ruin it." said Fluttershy upset.
"Yeah, we were gonna broke the sense out of Dash if it wasn't for you." said Twilight.
"Oh, I'm sorry, but there was no other way for you guys to know that, so I had to do what I had to do, I mean, come on, you guys would have resolve it by tell her to just stop it and that's it." said Discord.
"We did tell her." said Twilight.
"True, but you would have turn it into a conversation instead of just lazy oversaying." said Discord, causing Twilight with no word to contradict, she would have thought about that in the beinginng.
"Well, at least we all learn a lesson, we learn that never do things that looks right, but can't go right,
use Starlight as an example, and like I said before, a prank isn't very good when you're the only pony laughing." said Twilight. "And it will sound odd if I say this, but if it wasn't for Discord who ruined the prank, this lesson would have never been teached to us."
Everypony agreed on Twilight's words.
"And Rainbow, now seeing you mouth rainbowfied, I think it quite funny to see that." said Fluttershy as she giggled.
"Yeah, it was." said Rainbow Dash.
Everypony laughed, learning two lessons, Rainbow Dash learned to not to go far on pranks, while the ponies learned that wrongs don't make it right.
"Well, we all laughed at Rainbow's prank after all." said Starlight.
"Yeah indeed." said Twilight.
"You finally put effort on your prank now Dash." said Rarity.
"And this time, it wasn't lazy, hehe." said Applejack.
"Thanks. And that's why they call me and Pinkie, the prank masters, right Pinkie?" asked Rainbow Dash.
"Yup, we definitly are." chuckled Pinkie Pie.
"Now with that, Discord, would you?" asked Twilight as she looked at Discord.
"Of course." said Discord as he snapped his fingers to open another portal to Equestria.
The portal opened and Everypony went into the portal and it's was morning time in Ponyville, like in Danville, they all head to their homes and all got a good rest, it had been a night of them, but al least everything went back to normal.
The End.
