Three twenty seven PM, Seventh July Twenty twenty two

It was your ordinary, run-of-the-mill morning, which'll lead to an ordinary day, where evil scientists cause chaos and platypuses fight them, and kids build giant robots. Totally normal! Oh, and how could I forget the paranoid teenager? Alright, back to the story.

Now, in a certain yellow house with a red roof that wasn't on top of a hill, two boys were taking some parts for a gift they were gonna make that day for their sister. After the routinely “Hey Ferb, I know what we're gonna do today!”, in 3 seconds, the same triangular boy, Phineas said “Hey, where's Perry?” Where Perry is is part of an alternate storyline. A redux. They didn't care about that. Perry the Platypus will come back, and they know it. They brought the Portal to Mars and some tools. Oh, and some fairy dust.

They set up the tools in their backyard and began to modify the portal. Their older sister, the paranoid teen I mentioned earlier thought it was some Portal to Venus this time. She remembered that crazy experience, when all her friends were busy, and she took C-Y-L-B-F-F-S as ‘Candace you loser! Bad Friendships Fail, Stacy.’ it was actually ‘See you later best friend forever, Stacy.’ . Her misconception caused her to feel extremely depressed, and once she heard that in Baljeet, one of her brothers' friends' house, the boys were building a portal to a far away place, not knowing it was Mars, she went in, and became the queen. After trying to contact Earth using a Mars rover, and failing, she smashes it, revealing aliens, who were in hiding the whole time. A few minutes of ‘Queen of Mars’ later, she got back to her senses and was back to Earth. Candace shuddered at the thought. But she had made it her duty to protect her brothers from the crazy stuff they build, so she went out. "PHINEAS AND FERB YOU ARE SOOO BUSTED!!“

They weren't the least bit afraid of being busted. Besides, their building permits were in order! Phineas came to his sister ”Hey Candace! We made this for you!“ Candace said ”No, I am NOT gonna be Queen of Venus.“
Phineas laughed. ”Hey Ferb, I know what we're gonna do tomorrow, but first let's finish getting anthropomorphic ponies from a TV show Candace likes in here.“

”Wait.. anthropomorphic PONIES?? I'm calling Mom!! MOM!!!“ yelled Candace as she went upstairs to her room to get her phone.

Meanwhile, in a totally different universe, the purple alicorn princess Twilight Sparkle was testing out an inter-dimensional portal spell. 3 seconds before Phineas pushed the button on his end, Discord jumped in and did the exact same spell with a snap of his fingers. The snap and the button-push occurred at the exact same time, causing a sonic rainboom in both universes, and opening the portals. Twilight decided to step through the portal. She stepped in to see an ordinary backyard, with a huge tree in it. Phineas wanted to step in too, but Twilight stepped in first. She was followed by five other ponies, all of whom they recognised from a TV show their sister watches. The rainboom caught Candace's attention too, so she ran downstairs with her phone. ”What in the entire galaxy are Twilight Sparkle and her friends doing here? Phineas and FERB!!!!“

Pinkie Pie was the first to speak up. ”You guys have a friendship problem.. I knew that when my cutie mark glows, and my tail twitches, and my coat turns one shade lighter, there's an interdimensional friendship problem.“
Applejack added ”A family problem. The most serious type..“
Phineas asked ”Family problem? What?“
Twilight jumped in ”Have any of you been fighting recently?“
”Well, yes. We were fighting against aliens from Feebla-Oot yesterday with a free t-shirt cannon!“ Candace replied.
Rainbow Dash facepalmed. ”Amongst yourselves??“
Phineas quickly answered ”Uh, no.. but our sister has been down in the dumps yesterday. But the song in the end, I'm sure cheered her up!“

Twilight suggested that 3 ponies talk to Candace, and 3 ponies talk to Phineas and Ferb.

”So, Candace, darling, what happened? Your brother told me that you haven't been feeling yourself.“ said Rarity.
”Well, it's just that, my brothers, everyone thinks they're so special, but not me..“
”Sweetie Belle felt that way too, but now she's okay. Maybe it just takes a nice brother-sister experience to fix those bonds!“
”Yeah, every summer, we go to Winsome Falls, Rainbow Dash and her honorary sister, and me and Rarity, and our sisters!“ added Applejack
”Maybe you guys can have a fun family experience! Shining Armor, my big brother and I were inseparable!“ said Twilight, who was almost caught up in Candace's fanfiction crossover of Ducky Momo and the Avengers. ”By the way, you're a great writer!“
”You're right! Gosh, I can't believe that my favorite TV show comes to life, and are actually helping me with a friendship problem“

”All righty boys, what happened that made your sister totally sad?“ asked Pinkie Pie, in a detective hat, with a pipe in her mouth.
”Well, we never mean to hurt her feelings.. But, uh..“ said Phineas, in an unusual, confused mode.
”Well, it was us. We've been having an awesome summer, that we didn't pay attention to her feelings..“ added Ferb.
”Guys, show kindness to your sister.“ said Fluttershy. ”Yeah! Like how she's trying her best not to act stupid around Jeremy and keep her urges to bust you guys under control, and how she's got a low self-esteem!“ said Pinkie Pie.
”Wait.. how do you-“ ”Just a hunch! *wink*“
”Hey! Why don't you guys have a fun brother-sister activity? Maybe a visit to Equestria? The Wonderbolts' show is tomorrow, and I have 3 extra V.I.P tickets. I got 14 in total. 2 for my parents, 5 for the rest of my friends, 1 for Spike, 3 for the CMCs, which means 3 extra. Am I counting right Pinkie Pie?“
”Yep! oh, wait.. you forgot one!“ said Pinkie, who somehow managed to use a calculator with her hooves.
”Pinkie, I'm a Wonderbolt myself.“
”Sure! But first we better fix that portal.“

A portal fixing montage later, the ponies went in, and they put the portal in the garage.

1 day later

Phineas and Ferb were out in the backyard. So was Candace. The siblings pushed the portal into the backyard, as their dad was reading about a so-called ‘technicolor sonic boom’ on the news. At exactly 2:30 PM, which was 1:30 PM in Ponyville, Discord snapped his claw at the exact same time Ferb pushed a button, the rainboom happened again, and they stepped across. No body changes happened to them because they were from totally different universes. Not even close to each other in the clockwise movement of direction. They went in, and after getting the walk-on-clouds spell from Twilight, and inventing Equestria's Very First Plane, they arrived in the Cloudiseum for the show at 2 PM, Northern Equestrian Standard Time. After the hour-long show, they decided to go to Manehattan Escapes, the escape room. This is gonna be good… In only 10 minutes, because this plane was very fast. Faster than Rainbow herself.

The first puzzle for the siblings was a step on the right tiles puzzle like in Daring Do. ”A frog, newt, lizard and eel.“ said Candace in confusion. ”All of them are reptiles! Except eels!" said Phineas and Candace at the same time.

The second puzzle was a pattern puzzle. O-T-T-F-F-S-S-_-_-_ stumped them. But then Ferb facepalmed and placed the letters E,N and T in the blanks.

The third one was a 3-room puzzle. Fire (fake obvi), water (fake) or Ursa minor which had been left unfed for 3 months. This was easy. The Ursa door. If it wasn't fed for 3 months, then how'd it be alive? This was a common riddle kids asked each other at John P. Trystayte Middle, Phineas and Ferb's school.

While they were solving riddle after riddle, the ponies were also spying.

The last, and 10th riddle was a ‘where’s the key' thing. There was 1 blue key, 3 locked chests of different shades of blue. Candace was good at colours, so she immediately picked the 4th, which was the exact shade of blue as the key. In it, there was a key. They turned the key, and surprisingly beat the griffon record! That was a wild experience, and it certainly brought them together.
