PHINEAS AND FERB!!!" Candace yelled as she had another failed attempt to bust her brothers. Phineas, Ferb and their friends had built a whole theme park over the Danville city. That was not the first time those boys built something insane for their age. On the first day of summer they built a roller coaster that was carried away by a gigantic magnet made by Dr Doofenshmirtz.

"Anyone want snacks?" Asked their mom.

"I DO!!!" The kids yelled excitedly.

"Oh there you are Perry." Phineas said.

"Krkrkrkrkrkrkrkrkr." The platypus said bluntly.

Candace yet again failed to bust her brothers. Her mom never believed her until she saw it but Candace always got her to backyard late. When Candace got her to see what her brothers were doing, she was either dreaming or her mom's memory was erased.

"Candace dear would you come her." Her mother called from up the stairs. Candace dragged herself from the couch and up the stairs. Her mom and dad were busy packing clothes and essentials.

"Um mom where are you going?" Candace asked.

"That's what we were calling you for." Said their dad.

"We're going for a buisness trip in a few days so you're in charge." Her mom said.

Candace gasped. "So you going on a buisness trip and I'm in charge. Like control-Phineas-and-ferb in charge?!"

"Yes Candace."

"YEEEEEEEEEESSSSSSSS!! LET ME DELIVER THE GOOD NEWS TO THE BOYS!!" Candace dashed out of the room and before anyone could blink she was back with Phineas and Ferb.

"So you're leaving..." Phineas said.

"Yes dear." Said their mom.

"Oh we'll miss you. For how long will you be gone though?" Phineas asked.

"We'll be gone for two weeks. It's really argent buisness sweetie. We're leaving tomorrow morning. Why anything wrong?"

"No It's just that we'll miss you." Phineas said a few tears in his eyes.

"Awww sweetie we'll be back soon. Candace is going to take care of you two. Right Candace?" Asked mom.

"Yeah yeah I'll take care of them. After all they're my little brothers." Candace said crying a bit. Even if she didn't say it out loud everyone knew she would miss her parents. When they assured their kids they would be back, they all went to their rooms back to what they were doing.

In Phineas and Ferb's room

"I can't believe mom and dad are going for a trip without us. But they are going because of work so I can't blame them," said Phineas sitting on his bed and Ferb on his. Ferb just nodded his head and looked at his step brother.

"I know right," said the triangle- headed boy as if his brother said something. "But I guess it's for the best."

Perry now on Phineas's bed cried out, "Krkrkrkrkrkrkrkrkrkrkrkrkr" said the platypus.

"You're right Perry. Even if we'll miss them they'll still come back in two weeks. And we still have our caring older sister to take care of us," Phineas said.

"I will miss dad so much but as you said brother they'll come back." Ferb finally spoke in an English accent. Ferb loved his dad so much but they all knew it was for the best.

In Candace's room

"I know Stacey. I'll miss them sooooo much but they left me in charge," Candace said talking on her phone to her best friend.

'Hello boss' Stacey said jokingly, 'May I speak to my best friend. She was telling me something important.'

"Oh Stacey grow up."

Suddenly Candace heard a door being slammed open on Stacey's end of the phone. 'Stacey the computer is broken again. I was having a fire side girls meeting.' A girly voice said.

'Hold on Ginger I'll fix it later.' Stacey said angrily.

'Mom says you fix it now. We were discussing on going to the mayor and ask him to increase all wifi connections for better signal.' Ginger lied.

'Say no more. I'm on my way. Sorry Candace talk to you later.' Before anything else happened, Stacey hung up the phone. Now Candace with nothing else to do searched through her contacts until she found the person she was looking for. Her boyfriend Jeremy.

"Hi Jeremy," Candace said sheepishly.

'Oh hi Candace,' Jeremy replied at his end of the phone.

"So whatcha up to?"

'I was babysitting Suzy since my parents are gone out for the night,'

"Oh hey what's that in the background?"

'Suzy's just watching My Little Pony.'

"Ya mean that show with talking pastel ponies."

'Yes. Why? Do you watch it?' Jeremy asked teasingly.

"No no no no. I don't watch that childish show like ducky momo." She lied.

'Okay if you say so. Hey do you think I can call you later. Suzy's hungry." Jeremy asked.

"Um sure. Call you later I guess." Candace replied a little bit bummed out.

"Okay call ya later. Bye Candace
Jeremy said excitedly.

"Um bye I guess." After that Jeremy hung up. Suddenly Candace received a message from Stacey.

'Um Candace I've been lied to. There was no fire side girls meeting, Ginger just lied so I can wash the dishes. See you tomorrow then.'

"Phew nobody knows about my My Little Pony merch." Candace said relieved. Candace went down stairs to watch one of her favorite shows; Ducky Momo.

"So what's the next episode of Ducky Momo? Huh? What do you mean canceled?! Ugh Phineas and Ferb!!" Just not long Phineas and Ferb dashed down the steps. "Ducky momo is cancelled can you please..."

"See what the next episode is. Sure sis." Said Phineas. "Ferb I need a screwdriver, a drill, some nails, screws and the film for our gigantic camera."

Ferb ran upstairs and came back holding the things Phineas asked for. They ran round the TV as if they were racing to see who could complete the most laps. Once they slowed down, they turned on the TV and there it was; Ducky Momo. Candace was estatic. She thanked the boys so much and they went back to their room.

The next day

Phineas, Ferb and Candace woke up to see off their parents.

"We'll miss you mom and dad."Phineas said. "I hope you guys have a safe trip,"

"And bring us stuff from Canada. Make sure it's mostly maple syrup." Candace added.

"Okay dear we'll bring you maple syrup. Bye bye. Be good while we're gone." Said their mom.

"Bye mom, bye dad we'll miss you." Said Phineas, Ferb and Candace.

"Okay boys I'm gone to the house. Don't do anything you might regret." Said Candace once her parents were already gone.

"Okay Candace. Ferb I know what we're gonna do today." Said Phineas. Just then a girl with a pink dress, a light pink shirt inside and a Pinker bow on top of her head. She had neatly trimmed black hair.

"Hey Phineas whatcha doing?" Asked Isabella.

"Oh just thinking of building a portal to another dimension." Said Phineas.

"Hello Phineas, Ferb, Isabella." Said a short boy with brown skin and an Indian accent. "I couldn't help but overhear you were building a portal to another dimension."

"Right you are Baljeet. We're thinking of building a portal to Candace's favourite show." Phineas said. "Hey where is Buford?"

"He's still dressing up he will come. Oh here he is."

"Hello dweebs." Said a boy with a big body, short brown hair and a tooth sticking out of his mouth.

"Hey Buford." All the children said present.

"Good the whole gang is here so let's start." Said Phineas. After a few minutes they were already done. Told ya these kids were fast.

"Hey where's Perry?" Asked Ferb.

Turns out Perry the platypus is a secret agent for the agency of O.W.C.A.

"Agent P we're glad you're here," said a voice from a computer screen. It looked like a middle aged man known as Major Monogram. He was the one who owned the animal agency with his college assistant Carl.

"We heard that Doof is up to something and we need you to stop him from what he's doing. Now go thwart his plans Agent P." Added the major. Perry the platypus ran to his Jet Pack and flew towards the building where Dr Doofenshmirts lived.

Back to what the kids were doing
"Okay guys it's finished." said Phineas as he clapped his hands as a show of hard work.

'Oooo's and 'aaaa's could be heard from the five children. Candace came out to see what the boys have built.

"What a mirror? You guys are so... Oh mom and dad are gone. Ugh."Candace groaned in realisation.

"So what does this mirror do anyway?" Said Candace as she found it impossible to bust her brothers so chose to join their shenanigans.

"Well it's a portal to another dimension. One of your favourite shows actually." Said Isabella. At that moment Perry the platypus came back from thwarting Dr Doofenshmirts.

Candace gasped. "Tell me which one no surprise me." Candace was so excited.

"Okay. Ferb would you do the honour of flipping the switch." Ferb just nodded and went to the back of the machine. "So this machine will suck any creature here into the other dimension. Oh there you are Perry. Wanna come with us?"

The platypus just responded with a "Krkrkrkrkrkrkrkr!"

"I'll take that as a yes. Here we go." Said Phineas as the mirror changed and became spirals. They were immediately sucked in.

In the pony world (Equestria)

"WHAAAAAAT!!" They all yelled both in shock and excitement that it worked.

"WHAAAAAAT!!" The kids yelled both in excitement and shock that the portal actually worked.

"I can't believe that it worked." Phineas cried out. He was shocked. They were just building it for fun but it worked. It actually worked.

They were all somehow turned into ponies. Phineas was an earth pony Colt with an orangish yellowish coat colour, a messy red mane and tail and was still wearing his orange and cream yellow striped shirt. Ferb was a unicorn colt slightly tall for his age with a light tan shade of yellow coat, a messy green mane and tail and was still wearing some purple pants. Isabella was a Pegasus filly with a pink coat, a lighter pink t-shirt and dress, her pink bow still on her head. Her mane and tail were still neatly combed. Baljeet was a unicorn colt, had a brown coat, curly jet black mane and tail and had his light cyan t-shirt and his dark blue dungarees. Buford was an earth pony Colt with a grey coat, dark brown military mane and tail. He had his black shirt still on his body. Candace was a Pegasus mare with a red coat colour, her orange mane and tail also neatly combed. She had her normal clothing; a crimson red tank top and a white shirt. Perry was a dragon instead of a platypus. He had blueish greenish scales, his front was orange and had orange spikes.

Each of the ponies had a cutie mark. Phineas's cutie mark was a screwdriver and a brain cause of his rare imagination. Ferb's was a hammer and the British flag. Isabella's was a sash with a single patch with a heart on the patch. Baljeet's was a pair of spectacles the frames shaped as light bulbs. Buford's was just a clenched fist and a pair of glasses. Candace's cutie mark was just a pink cell phone.

Where the kids were looked like a crystal castle. They all stood up and found out they had hooves. They stood up on their back hooves but immediately toppled over.

"Um guys, were ponies of course we can't stand on our back legs or for now hooves." Just then Perry cleared his throat and magically spoke and the others were shocked to hear the lovely pet of Phineas and Ferb actually spoke clearly.

"Where am I? Wait did I just speak?!" The former platypus was shocked himself. He had a little voice that sounded like a five year old speaking.

"Um that was unexpected!" Ferb said with his British accent.

"Indeed Ferb. Indeed." Phineas said with a face that said; 'my pet can speak and I can understand him.' Candace still in shock from all this was just standing there her mouth dangling wide open and she didn't even blink once.

"Uh Phineas, I think something's wrong with your sister." Buford said looking at Phineas with a face of concern.

"Hmm, Candace wake up." Phineas yelled.

Suddenly Candace let out a squeal of joy. "Am I dreaming?" Candace asked." If I'm not dreaming, please I suggest you cover your ears."

Everypony reached for where their ears once we're but realized they weren't there. They reached the top of their heads but not before Candace started.

"Eeeeeeeee We're in one of my favorite shows and now here comes Spike who will look at us in shock and will immediately go call Twlight and..."

As she said Spike was busy eating some gems when he heard a strong burst of magic coming from the library where they kept the mirror portal to Canterlot high. He just thought that someone had accidentally leaned and fell through the portal. He just ignored it. Twilight was on a friendship quest with Applejack so Spike was home alone. He ignored it until he heard a girlyish scream. That was when he stood up and ran to check it out. When he reached there he was shocked to find six ponies and a dragon neither he nor Twilight had seen or known from both worlds. That was when Twilight and Aj came through the door as their friendship quest was already resolved. That was when the screaming started.

"Twilight thank goodness you're here. There's intruders in the castle. Six ponies and a dragon." Spike said.

"Where?" Twilight asked concerned that they were being robbed.

"In the library. Where the mirror is."

"Oh no!" Aj said, "Better go see what they want."

Candace finally stopped screaming and looked towards the door of the library. She then pointed at the door to assure them that they were being watched by Twilight, Applejack and Spike.

"What in tarnation is goin' on in here?!" Asked Applejack in her country accent.

"Yeah what is going on in here. How did you fillies and colts get in here!" Twilight said infuriating.

"Well I'm Phineas, my brother Ferb, my sister Candace, and my friends Isabella, Baljeet and Buford." Said Phineas pointing to the ponies around him respectively. "And this is our pet Perry the platypus. Though he's a dragon now." He Chuckled.

"Oh hello nice to meet you." Spike said politely. "Hi Perry I'm Spike wanna be friends?"

"Um sure." Perry said finally finding his first friend apart from Phineas and Ferb.

"Great let's go. Wanna see what my favorite snack is?"

"Yeah!" Said Perry excitedly. He followed Spike to Sugar Cube Corner.

"We'll see ya later Perry. Don't run away like you always do back at home." Phineas yelled out to Perry.

"Don't worry I won't!" Perry yelled back.

"Sooooo..." Started Buford.

"Hi we're new in town and well we are kinda from another dimension." Isabella said but neither Twilight nor AppleJack were listening. They were busy looking at the broken pieces of glass on the floor. The mirror had shattered when they came through the portal.

"Say were you humans before you came to this world?" Twilight asked curiously.

"Actually yes we were humans before we came to this pony world. If you don't mind me asking how can you talk while you are well ponies?" Asked Phineas.

"Well in Equestria many creatures that can't talk in the human world can talk. Wait did you just say you came from the human world?" Twilight asked completely all ears now.

"Well yes we did say we came from the human world. Why is that bad?" Asked the Earth pony redhead.

"Are you familiar with CHS?"

"No not familiar with CHS."

Twilight gasped. "Do you know what this means Applejack?" the country girl just shook her head not knowing what she meant by do you know what it means if it was either excited or shocked.

"It means there are other dimensions apart from Equestria and CHS." Everyone gasped shocked.

"Wait let me get this straight," Applejack said, "There are other dimensions apart from Equestria and The other human world?"

"I believe so." Twilight replied.

Candace was trying not to squeal but she just couldn't. She let out a small squeal from the corner of her mouth that nopony heard. She was so excited that characters from one of her favorite shows. Phineas and Ferb were also happy that their invention also worked. It wasn't much of a surprise to them since everything they built actually worked. Buford was just there for the fun and since he was with his best friends and best nerd Baljeet. Baljeet was so excited since he would get to study about an alternate dimension and do some practical work too. I was somehow a dream come true to the Indian boy.

Isabella was also happy since she could spend the day or Celestia knows how long with her crush Phineas Flynn.

"Hey do you know where Pinkie Pie is?" Isabella asked.

"Oh she's at Sugar Cube... Hey how do you know who Pinkie Pie is?" Aj asked the eleven year old filly.

"Oh um..." Isabella started sweating profusely until Phineas stepped in.

"Oh just a hunch," Phineas said. Isabella sighed dreamily.

'Hmmm He saved me'Isabella thought.

"Uh Isabella, hello Equestria to Isabella. Pinkie is at Sugar cube..." Before Applejack could finish talking Isabella dashed to Sugar Cube Corner.

"...Corner. Why doesn't anypony let me finish ma sentences!!" The country mare said angrily.

"Hey Aj know where Rarity is? Before you ask I do know who Rarity is. She's the greatest fashion forward pony in all of Equestria. She has boutiques in Canterlot, Manehatten and here in Ponyville." Candace said. Twilight and Applejack were shocked to find out how much that mare knew about Rarity.

"Well Rarity sure will be happy you know you know that much about her Candace," Twilight said,

"I know." She said with pride.

"...well she's at Carousel Boutique right now."

"Great thanks." Candace dashed out of the castle as she knew where Carousel Boutique was.

"Hey dweeb wanna go to town square and help me paint it red?" Buford asked Baljeet.

"No. I want to stay here with Twilight and Applejack." Baljeet said.

Just then there was thunder and lightning was heard. Baljeet, Phineas and Ferb all jumped butt Twilight, Applejack and Buford. Suddenly Discord appeared.

"AAAAAAHHHH!!!" Phineas, Ferb and Baljeet yelled.

"What is that creature?!" Ferb asked in disgust.

"HOW DARE YOU. I'VE NEVER BEEN SO INSULTED IN MY LIFE. WELL MAYBE I HAVE." Discord yelled.

"I for one think you look cool," said Buford. "It's like a science experiment gone wrong and that is one definition of cool."

"Aww. I'm fluttered. You look like a cool colt too. Like a military colt that's in a ruthless gang of bikers."

"Well I'll look exactly like one if I had a leather jacket though."

"Well here you go." Discord said as he snapped his claw and a leather jacket and sun glasses appeared on Buford.

"Woah! How'd ya do that now?!" Buford asked as he stared at the draconaquus in awe.

"Well I'm Discord: The spirit of chaos and disharmony."

"Woah nice to meet you Discord. I'm Buford. Wanna hang out?"

"Does a duck breathe heavily?"

"I'll say yes."

"Of coarse I'll join you in mischief my boy. Town square isn't gonna paint itself red." Discord said while poofing a bucket of red paint.

"You read my mind. Literally. See you dweebs later." Just then Discord teleported the both of them to town square.

Isabella

Isabella was busy humming a tune as she walked to Sugar Cube Corner when she bumped into three fillies. A Pegasus, a unicorn and an earth pony. You can guess who they were. Yes it were none other than the cutie mark crusaders.

Apple Bloom, Scootaloo and Sweetie Belle already had their cutie marks but they still did crusading cause it was still fun. They were going to try doing some scooter tricks Scootaloo was going to teach them.

"Ow! Hello. Didn't see you there. I'm sorry." Apologized Isabella.

"It's okay. We weren't watching where we were going either." Scootaloo said.

"Hi I'm Isabella Garcia- Shapiro. Nice to meet you."

"Hi we're the Cutie Mark Crusaders. I'm Apple Bloom, she's Scootaloo and she's Sweetie Belle." Apple Bloom said pointing at her friends respectively. "Nice to meet you too."

"Hey is the Cutie Mark Crusaders like a club or a scout troop?" Isabella asked curiously.

"Well both actually. We used to be a club that focused on getting cutie marks until one day we got these sweet babies by helping one of our school's greatest bullies. So we became a club devoted to helping others get their cutie marks or those who have cutie mark problems." Said Scootaloo with as much pride as Rainbow Dash's cockiness.

"Wow." Isabella said in amazement. "Where I come from, I have a group of girl scouts called 'the Fireside girls'."

"Cool!" The three fillies cooed.

"Hey wanna hang out?" Scootaloo asked the other Pegasus.

"Oh sure." Said Isabella excitedly to have already made friends in the alternate dimension. "So what do you guys do apart from helping with cutie mark problems?"

"We usually do crusadin' for fun these days so not much but try out other stuff." Apple Bloom answered.

"Oh okay. Let's crusade then." Said Isabella determined.

"Are you sure you wanna join our club?" Sweetie Belle asked in confusion.

"Yes you silly filly." Said Isabella. "Seems harmless to me."

"Okay then. We had to practice scooter tricks." Scootaloo said excitedly.

"What are we waitin' for. Let's go." Said Apple Bloom.

Isabella followed the three fillies to a hill in the out skirts of Ponyville. There were ramps where Scootaloo usually practiced her scooter tricks.

"Here we are guys. My somehow home I guess," Scootaloo said.

"Or as we like to call it Scootaloo's nest," Apple Bloom whispered to Isabella. She just snickered.

"Hey I heard that!!" Scootaloo said in an angry tone. Let us when the laughing got louder and Sweetie Belle and Apple Bloom joined in. Not long after hearing the laughing Scootaloo joined the laugh parade.

"Anyway Isabella since you are our guest today how about you started off with the scooter tricks you know," Sweetie Belle said.

"Um okay I'll try," Isabella said nervously. She took the scooter from Scootaloo and went on top of the second tallest ramp.

'Here goes nothing I guess,' Isabella thought to herself. She breathed in and out heavily. She held the handle of the scooter with her front hooves and put her back right good on the scooter the other one to push her down the ramp. When she pushed herself down and put her other hoof on the scooter, she started rolling down the ramp. When she reached the jump, she was flying in the still on the scooter. she let go and started flying through the air without flapping her wings. she did a triple backflip in the air and when the scooter landed on the ground she landed safely on it without damaging it. The other three fillies were speechless especially Scootaloo.

"That. Was
Awesome. Can you do that again?" Sweetie Belle said. Scootaloo's mouth was dangling open for a few months minutes.

"Is she going to be okay?" Isabella asked Apple Bloom.

"Yep. She's comin' back in three, two one," Apple Bloom said and pointed a hoof towards Scootaloo. Just as she said she came back to conscious as soon as Apple Bloom finished her countdown.

"You filly are awesome. Not even I have ever done such a trick! Can you be my 'Senpai' Please?!"

"Gladly," Isabella said proudly as she had found new friends.

Perry and Spike were walking down the road to Sugar Cube Corner while chatting as Spike showed Perry see of the sights they passed on their way. When they arrived at Sugar Cube Corner, Spike asked Perry to wait for him as he went for a very special cupcake.

"Hey Perry could you please wait for me. There's a special cupcake that I need to pick up,"

"Sure I'll wait,"

Spike went to the counter and ordered two cupcakes.

"Hey Mrs Cake,"

"Oh hello there Spike. Nice to see you again. What can I getcha?" Cupcake asked the purple dragon.

"Oh I'd like two gem cupcakes please. One for me and the other one for that friendly dragon over there," Spike said as he placed ten bits on the counter.

"Okay. Two gem cakes coming right up," Cupcake said turning away to go to the kitchen.

Spike then went to the table Perry was sitting at. He sat next to him and asked a few questions as they waited for the cupcakes. Ding! The bell rang as their order was sitting at the counter, Mrs Cake going to get it.

"So what's it like being a platypus? I mean you said you're from another dimension." Spike asked Perry with curiosity.

"Well, it's okay I guess. I mean being a platypus means you practically do nothing. And we also sweat milk and..."

"Ewwww! You sweat milk!? Gross!" Spike gagged at the thought of sweating milk.

"Yeah and..." Perry started but was interrupted by something beeping.

'beep beep beep beep'

"What's that noise?" Spike asked. Perry looked nervous and was sweating like crazy.

"Agent P, Doofenshmirtz is... Uh Carl, something's wrong with Agent P..." The wrist watch on his claw started talking.

"Woah, Cool! What is that?" Spike stared in awe at the device.

"Here you go dearies." Cup Cake said as she gave the two dragons their cupcakes and walked back to the counter.

"Thanks Mrs Cake." Spike said picking a cupcake from the plate.

"Now back to business. What's that?" Spike asked taking a bite from his cupcake.

"Major Monogram, It's me, Agent P." Perry said.

"Great googly moogly! Carl, Agent P can talk!"

"Yes sir. I heard" Another voice said.

"Woah. Sweet." Spike said still looking at the watch in awe and curiosity.

"I had reached home to my owners after a successful mission. Turns out they weren't done with the day's experiment and opened a portal to another dimension. Which is were I am now." Perry explained.

"Well I guess that makes sense. Anyway back to your mission. Doofenshmirtz has been spotted making some kind of dimension-inator. We are pretty sure that he's building it to come to the dimension you are currently in. You need to stop him once he arrives. Monogram out." The major said as the watch switched off.

Perry looked at Spike who was dumbstruck.

"Guessing you want an explanation?" Perry asked to which he received a nod from Spike.

"You see, I'm a secret agent. At an agency called O.W.C.A."

"That... Is... Awesome!!!" Spike said amazed. "My new best friend is a secret agent!!!"

"Not too loud Spike." Perry said.

"Oh sorry. It's just AAHHH!!"

"Let me guess again. You want me to teach you everything I know right?" Perry asked again to which he received a very enthusiastic nod from Spike. "Sure. I don't mind sparing some knowledge." Perry said chuckling.
