"Mom! Phineas and Ferb built another massive thing in the backyard. You gotta come home and bust them!" Candace yelled at her phone.

"Candace, honey, I'm busy." Mrs. Flynn-Fletcher sighed, "You're going to have to wait for me to see the 'massive thing' in the backyard for now." She hit the end button.

"No no Mom!" Candace screamed, "Don't hang up!" but the cellphone gave a loud beep. "Grrrrrrrr!" Candace growled, "I'll just go get her myself." and she stormed down the street.

On the other side of the street, Susan and Mary were stressing about how they had no lab to work in.

"–And the portable lab was inside the original lab, and it got blown up with the original lab, so now we have a whole day with no inventions!" complained Mary.

"Urrrrrg!" growled Susan, "If Johnny hadn't– " but she stopped as she saw a giant race track rising out of someone's backyard.

"Johnny!" Susan shouted, "He used our construction drones! Not only without permission, but they're supposed to be fixing up the street! Oh, he's so in trouble!"

"JOHHHHNYYYY!" Susan and Mary yelled, running down one side of the street.

"Phineas and Ferb, you two are soooo busted!" Candace shouted, running down from the other.

Nobody paid attention to where they were heading, and Candace, Susan and Mary ran into each other.

"Owwww! Watch where you're going– Wait, who are you?" Candace got up, clutching her head.

"I'm Susan Test, and this is my twin sister Mary." Susan explained, "Who are you?"

"I'm Candace, Candace Flynn." Candace held out her hand. "Sorry about running into you. I was trying to bust my brothers to my mom, and didn't see where I was going."

"It's fine," Mary assured her, "We were just on our way to bust our brother, to our mom. Or dad, whoever we find first."

"You know, I don't know everyone in Danville," Candace commented, "But I've only seen one pharmacist, and he's Vanessa's dad."

"Pharmacists!" Susan said angrily, "We're not pharmacists. We're scientists. What makes you say that?"

"We just kind of assume anyone in a lab coat is a pharmacist." Candace explained, "It's kind of a Danville thing. So why are you here?"

"We're staying in Danville for the day, while we wait for our construction drones to rebuild our street." Mary said, "Our annoying little brother blew it up."

"Sounds like something my little brothers would do." Candace sighed.

"Your brothers like to blow things up?" Susan asked.

"Well… not exactly." Candace remembered, "They like to build giant things like rollercoasters, or spaceships. But they definitely have the ability to blow up a street."

"We could build things like rollercoasters or spaceships," Susan bragged, "But Mary and I would rather focus our energy on developing machines that will help mankind. Johnny is the kind of person who would steal our construction drones to build that dangerous thing." she finished, pointing at Phineas and Ferb's hoverboard track.

"Oh, no. You're brother didn't steal your drone things, or whatever, to build that." Candace stated cooly, "My little brothers built that. That's our backyard."

"Did they use drones to build it?" Mary questioned with a slight sneer.

"Oh, no." Candace stated again, "My little brothers don't need robots to do their bidding. They do it themselves."

"Well, have your little brothers built a time machine?" Susan asked, drawing up to Candace's height.

"Oh, yeah. They took me and traveled in time. Twice!" replied Candace.

"Well, we put Johnny into a Tinymon video game. Twice!" countered Mary.

"My brothers put me into a video game! But I totally beat the system! And so did they!" yelled Candace.

"We made an alternate reality world, where we battled to the death with Johnny several times!" shouted Susan.

"My little brothers Phineas and Ferb made an animal translator!" Candace screamed.

"We made Johnny a pet dog that can speak and pretends he's a kid with a hairy skin disorder!" yelled Mary.

"Phineas and Ferb have a pet platypus!"

"We turned Johnny into a mouse and a dog!"

"Phineas and Ferb turned me into a platypus by switching my brain with their pet!"

"We switched Johnny and Dad's brains so they could see what it's like to live the other's life!"

"Phineas and Ferb switched brains with intergalactic alien fugitives who like to listen to square dancing!"

"We gave Johnny a pink princess dress that shot lasers!"

"Phineas, Ferb, and I spent a day fighting pharmaceutical zombies!"

"We gave Johnny a winter coat that had the ability to ward off an alien invasion!"

"There are only 104 days of summer vacation and somehow Phineas and Ferb have made it longer!"

"We invented the cure for the common cold!"

"Phineas and Ferb took me around the world in one day!"

"We made Johnny a hit on the internet!"

"Phineas and Ferb sing perfectly choreographed songs with no discernible music source!"

"We traveled to a planet made entirely of meat!"

"Ferb is British, and Phineas's head is shaped like a triangle!"

"Fine." said Susan, "We'll prove to you that we can invent better things than this 'Phineas and Ferb.' We'll have a contest."

"A contest, huh?" Candace said, "Phineas and Ferb once had a contest about who could build a better fort with these other kids, and the other kids just had a licorice dispenser, but my brothers had a wind tunnel room, and an orchestra, and they totally beat the other kids by a landslide! They can do it again…"

"Take us to your brothers!" Mary commanded, "And we'll prove we can do better than wind tunnel rooms and orchestras.


Isabella walked to the Fireside Girls cabin on the other side of town with the cupcakes she planned to sell.

"Okay, girls!" she announced to her troop, "We have fifty Fireside Girl Cupcake Boxes to sell by the end of the day. Gretchen, take Milly and go to the north side of town. Katie, you and Ginger go to Danville Harbor. Adyson, you and Holly cover the suburbs, and I'll take downtown. Let's go, girls!"

"Aye aye, Isabella!" saluted Gretchen.

"Isn't it weird that the Fireside Girl Cupcake Boxes are shaped like logs?" Katie remarked.


Isabella headed to the downtown area of Danville with her Fireside Girl Cupcakes. She entered a large purple building that reminded her vaguely of Ferb's head. Isabella took the elevator to the top floor. She knocked on the first door on the floor.

It opened, and a man in a lab coat with a long nose, who Isabella recognized as the pharmacist who had accidentally started the pharmaceutical zombie apocalypse from a couple days earlier.

"Would you be interested in buying some Fireside Girl Cupcake-" Isabella started, but was interrupted as a girl with blond hair and a green uniform stood in front of her.

"Would you be willing to help donate to the Ladybird Scout foundation by buying some Ladybird Scout Cookies? They're limited edition, only here today!" she told the pharmacist.

"Excuse me!" Isabella pushed her away, "I was here first!"

"You know, I'm kinda busy right now," the pharmacist apologized, "I have to get ready to trap my nemesis. He should be here any minute…" he was struck with a certain thought, "...Although, if I eat enough cookies I might get into a big enough sugar rush to make his trap way over complicated! I'll take ten boxes of Larrybug Scout cookies!"

He shoved money into the other scout's hand, and took ten cookie boxes. Then he shut the door.

"You just stole my customer!" Isabella said angrily.

"You just don't have good marketing skills." the blond hair girl said smugly.

"I need to sell fifty boxes of cupcakes to fund our next field trip!" Isabella protested.

"And I need to make the most of these customers that haven't had any of my Ladybird Scout Cookies yet." the girl replied.

"You can do it away from my troop!" Isabella commanded, "The Fireside Girls are way better at earning patches and selling any kind of sweets than any other kind of scout troop!"

"Oh, yeah?" the Ladybird Scout asked annoyingly, "Prove it!"

Isabella thought for a moment. "Phineas and Ferb!" she exclaimed.

"Phineas and what?" the girl asked.

"Phineas and Ferb!" Isabella said again, "They built a hoverboard track in their backyard! We can race on it! And whoever wins can't sell anymore cupcakes or cookies in this part of town."

"A hoverboard track?" the blond girl repeated, "I can race on a hoverboard track. I've beaten Johnny at stuff like this lots of times. But," she paused, "Let's raise the stakes even higher. Not only can the loser not sell in this part of town, they can't sell at all! And they have to buy the rest of the other's cookies."

"Deal." said Isabella.


*Doofenshmirtz Evil Incorporated*

Perry jumped out of his hovercar, and smashed through the roof of Doofenshmirtz Evil Incorporated.

*Perry!*

Just then, a large metal canister fell on him.

"Perry the Platypus," Dr. Doofenshmirtz said as he stepped into the light, "How... uhhh…" he stopped and thought for a moment, "Expected I guess…? I mean you come here every day, so I mean why wouldn't you be expected? It makes no sense. Anyway-"

But he was interrupted with a cry from above.

"How do you steer this thing!"

"Where we supposed to jump off too?"

Mr. Black and Mr. White were still on Perry's hovercar, and they crashed it through another hole in the ceiling, and right onto Doofenshmirtz.

"Oww." said the evil scientist.

"Uhh… Sorry about that." Mr. White said, "We weren't sure how to land this thing."

"Again, Oww." Doofenshmirtz repeated, "Anyway..." he moved away from them carefully, "You are now…" he pressed a button on a remote, "Trapped! Ha ha ha!" but nothing happened. Mr. Black and Mr. White looked up expectantly. Mr. Black shrugged.

"Uhh… he he…" Doofenshmirtz apologized, as he fiddled with the remote, "And there!" he exclaimed as two other metal canisters fell on Mr. Black and Mr. White. "Trapped!" the canisters were squeezing Mr. Black and Mr. White.

"Sorry for the tight fit," Doofenshmirtz apologized, "All my traps are platypus sized. I was on a sugar rush when I built them."

There were ten empty Ladybird Scout Cookie Boxes open nearby.

"Now, you are probably wondering why I'm not wondering why I have two more agents coming to thwart my evil schemes. And the answer is simple, as I'm sure Major Monogram, and whoever your boss is, has told you, I have made an evil ally! Dark Vegan!" lightning flashed, and dramatic flashed. But nobody appeared.

"Uhh… Dark Vegan!" Doof said again. Lightning flashed and dramatic music played. But Vegan did not appear. "Excuse me for a minute." Doofenshmirtz walked over to the kitchen.

"Dark Vegan, you're supposed to come over when I say 'I have made an evil ally, Dark Vegan,' so it's all dramatic!" Doof explained.

Vegan was eating some toast. "I just couldn't say no to this toast!" he replied.

"After we take over the Tri-State Area, you can raid all the bakeries, but first I have to introduce you to my nemesis!" Doofenshmirtz stated.

"Now," Doof walked back over to where the three agents were trapped, "I have made an evil ally! DARK VEGAN!" dramatic music and lightning flashed, as Dark Vegan appeared, holding up his laser sword.

"See, dramatic." Doof explained, "Totally worth it."

Perry rolled his eyes.

"Anyway," Doofenshmirtz continued, "I was browsing the web this morning, and found out that some idiot kid blew up a street, and all of the sudden it caught my eye that an evil intergalactic alien needed a place to stay for the day, and needed an evil ally to help him get revenge on the idiot kid that blew up his street! Of course, he also wanted to be in the same building as the idiot kid that blew up his street, just like everyone else on that street, so I also had to rent the bottom floors of my building out."

Everyone on Johnny's street was staying in the Doofenshmirtz Evil Inc. building.

"...Anyway," Doof said, "You, know, again. Dark Vegan promised to help me take over the Tri-State Area if I helped him get revenge on the idiot kid that blew up his street, so with our ingenious minds together, I have created, the Teleporter!… inator." Doofenshmirtz unveiled a machine that was covered by a sheet.

"Whoever I hit with this -Inator will be instantly teleported to my lab! So all we have to do is find the idiot kid who blew up the street, and shoot him, and he'll be teleported here and Dark Vegan can get revenge on him." Doof paused for a second looking pleased, "... Oh I just had another idea!" he exclaimed, "If I shoot my brother Roger with this, then he will get teleported to my lab, and then I can just waltz in and take over the Tri-State Area, you know, somehow, and if anyone tries to stop me, than Dark Vegan will stop them… somehow. I just thought of that now."

Perry rolled his eyes again.

"Wait a minute," said Mr. White, "Isn't Johnny staying in this building then? You do realize you could just go downstairs and grab him?"

"Well, yeah," said Doofenshmirtz, "But that would mean walking across the lab, opening the door, possibly dodging scouts selling cookies, and walking downstairs- It's too much work. This is much easier."

Perry was wearing a just-a-normal-everyday-thing-I-have-to-put-up-with expression.

"Anyway," Doof continued, "Dark Vegan, meet my nemesis!" lightning flashed and dramatic music played.

"Uhh… which one is your nemesis?" Dark Vegan asked.

"That one." Doof explained.

"Mr. Black?" Vegan asked.

"He's your nemesis?" Mr. White asked Mr. Black.

"No, no, him!" Doofenshmirtz repeated.

"Mr. White?" Vegan asked.

"He's your nemesis?" Mr. Black asked Mr. White.

"No!" exclaimed an exasperated Doofenshmirtz, "The platypus! That's secret agent Perry the Platypus!" he paused for a second. "Wow, deja'vu."

"The platypus?" Dark Vegan repeated, "But he's just a platypus. They don't do much."

"No, but look!" Doof exclaimed, "He has a cute little platypus hat."

Perry chattered.

"Well, okay," replied Vegan, "But where's my nemesis? I thought Johnny Test would be here to stop me."

"Well, we were gonna have Johnny do it," said Mr. White, "But he already met Agent P's owners, and we couldn't risk him finding out his other secret double secret agent life."

"Wait a minute!" shouted Doof, "You just said 'secret' twice in that sentence." he paused for a second, "Wait another minute! If you expected Johnny to come stop you, why did I build a Teleporter… inator?"

"I guess I didn't really think that through," Dark Vegan admitted, "But I was distracted by toast!"

"Fair enough, I guess." sighed Doofenshmirtz, "I've been distracted by things like that. I once spent an entire day trying to build an Almond-Brittle-Inator, and then realized I didn't have any almonds…"

Vanessa walked into the kitchen. Jillian was sitting there.

"It looks like my dad has another impossible scheme." Vanessa sighed, "What're you here for?"

"My dad allied with your dad to help him get revenge on my friend Johnny Test," Jillian explained.

"Well it's not everyday I meet someone who has as crazy of a dad as I do." Vanessa replied, "What's the craziest thing your dad has ever done?"

"It's not what he's done, it's what he tries to do." said Jillian, "He's obsessed with this Earth food 'toast,' and he has a laser sword that uses batteries or needs to be plugged in. He always tries to get revenge on Johnny for stranding us here on Earth, even though we have the ability to go back to our planet."

"Why doesn't he want to go back to your planet?" Vanessa asked.

"It doesn't have any toast." Jillian sighed.

"Ah, of course." Vanessa replied.

"You don't seem surprised to meet someone from another planet." Jillian remarked.

"I've seen plenty of crazy pretty things around here." Vanessa sighed, "My uncle is the mayor of Danville, and my dad always tries to become the ruler of the Tri-State Area by creating 'inators' to shoot him with. And they always fail because of a platypus."

"Wow, that is crazy." Jillian said.

"He once tried to make my uncle ugly," Vanessa remembered, "And ended up creating a zombie apocalypse of himself. It got pretty weird."

"Yeah, I'll bet." Jillian replied.

They both sat in silence for awhile.

"Does anyone want some muffins?" asked Norm.

Hope you guys liked this chapter, it was pretty long. In the future, I will probably be doing more Phineas and Ferb crossovers. I plan to do a Zootopia, Doctor Who, and possibly a Harry Potter one. I don't know how often the chapters will update, but I'll try to do it fast.
