"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.
