I originally wrote this story in 2012 in Polish - it was my first Phineas and Ferb story ever :D Now I'm translating it into English and uploading in parts. There're only some minor changes. Please forgive me for the mistakes, since I'm not a native speaker of English.

Doofenshmirtz Evil Incorporated!

Heinz Doofenshmirtz was working on his new diabolical inator. It looked like a tank but was painted in pink, had two numbered buttons and three cannons. One of the cannons was big and the two others were a bit smaller and were located just under the bigger cannon. The tank itself wasn't very big.

"It's ready. I shall give it a try," Doofenshmirtz said. "But where's my nemesis? I'm not gonna start without him!"

Suddenly, Agent P loudly destroyed the door and jumped inside.

"Oh, Perry the Platypus!" Doof said. "You've finally arrived! I started to worry that you wouldn't come!"

Suddenly, a box made of glass, without the lower base and with tiny holes for breathing, fell on Perry and trapped him.

"A simple trap seems to work best," Heinz said. "I was expecting you earlier. Did the Organization Without a Cool Acronym worsen? Or maybe I improved? I was trying to buy weird tools and a pink paint without OWCA noticing but eventually, you noticed. Never mind. Behold, it's my Fall in Love-inator! When I press the first button, a ray will be shot from the biggest cannon. Whoever is hit by the ray, will fall in love with the person who shot. The second button will cause the two smaller cannons to shoot two rays which will hit two persons. This will make the persons fall in love with each other. A person affected by the inator will be back to normal if they're hit again and they won't remember the time of the "curse". I'll make Charlene fall in love with me again so that she'll give me more money. I'll also cause teenage infatuations which will annoy the parents. I'll cure their children for them – but only if they pay me! I'll be very rich and I'll buy the entire Tri-State Area! HAHAHA! I hope my monologue didn't make you bored. I'm gonna test the inator but first, I should plug it in."

Suddenly, an idea appeared in Perry's mind. He wasn't able to break free that quickly but still, he could stop Heinz, since Doof was searching for the socket and didn't pay attention to the platypus. Perry took a dynamite out of his pocket, lit it and threw it through the tiny hole at Fall in Love-inator. Doofenshmirtz plugged in the machine and was going to shoot two random pedestrians, while he noticed a flying dynamite. Instinctively, he jumped away but he accidentally hit the inator which subsequently shot two rays in a different, unknown direction. Immediately afterwards, the dynamite hit the inator and exploded. Obviously, the machine was totally destroyed. In the meantime, Perry was able to destroy glass with his tools and he flew away on a parachute. He hoped that the rays hadn't hit anyone. While flying away, he heard Doofenshmirtz's shout,

"Curse you, Perry the Platypus!"

Meanwhile, Phineas and Ferb went to the their backyard, thinking about what they should do that day.

"Hey, Ferb!" Phineas said. "Do you remember our various songs? I know what we're gonna do today. Let's build Huge Dance Party House!"

The boys started working on their Big Idea. Soon afterwards, Candace came to the backyard too and approached her brothers.

"A-ha! Here you are, you little brats!" she said. "You're doing something wrong again but I'm gonna bust you!"

She laughed maniacally and called Linda.

"Hi, Candace," her mom greeted her. "I can't talk with you now. I'm on an important meeting. Call me later. Bye, sweetie!"

"I'm not gonna give up that easily," Candace thought. She decided to wait for a good moment to bust her brothers. "When they build more, I'll take a pic and send it to mom!"

She hid in her room and started spying on them.

Then, Isabella came to the backyard and said,

"Hi, Phineas! What'cha doin'?"

"Hi, Isabella!" Phin greeted her happily. "We're preparing the coolest dance party ever! Wanna help us?"

"I'd love too but I really can't, I'm sorry," she said sadly. "There's a new Fireside Girl in my troop and she has to earn the Help Build Something Without Being Accompanied by Other Fireside Girls Patch. She'll come here in a moment if you don't mind. Meanwhile, I've gotta go earn more patches with other girls in my troop. See ya!"

"OK, see you later, Isabella!" Phineas said.

Isa wasn't very happy. A day without Phineas is never a good day. But she really cared about her troop and wanted to earn more patches with the girls. She reluctantly went to the Fireside Girl Lodge.

"Hey, Ferb!" Phineas said. "I think we'll have to order some materials. Hey, look! Buford and Baljeet are coming!"

The bully and the nerd were coming indeed. They seemed to be annoyed.

"Hi, guys!" Phin greeted them. "Why are you annoyed?"

"This nerd stole my lollipop," Buford replied.

"Earlier you stole my ice-cream," Baljeet said angrily. "So I thought that it had given me the right to stole your lollipop."

"Don't worry, dudes," Phineas calmed them down. "We have lots of desserts in our house. You can come in and have some!"

"YAY!" Buford and Baljeet said in the same time.

Having taken some desserts, they decided to help Phineas and Ferb with their project.

"What are you buildin', by the way?" Buford asked.

"The coolest dance party ever," this time Ferb answered.

"I'm not sure if I'd like such a thing," the bully said. "Though, if there'll be good food… Anyway, I'll help ya!"

"I think it will be a good opportunity to learn something interesting," Baljeet said. "Maybe practice dancing?"

"What? HAHAHA!" Buford laughed. "I think that my grandma can dance better than you."

"That is not true. You will see."

Phineas decided to stop their senseless argument so he told them,

"Baljeet, you'll help us with computations. Buford, you'll help by carrying heavy stuff. I'll join you in a moment but I've gotta order some stuff first. We'll also have to invite dancers but we'll do it later."

Candace was in her room, looking through the window all the time and spying on the boys. It was boring but she didn't want to miss the opportunity to bust them. Suddenly, Stacy entered her room.

"Hi, Candace… What on earth are you doing?"

"This time I'm not gonna fail," Candace responded, without even looking at her friend. "They're building a dance party house. I'm gonna watch them all the time and in the right moment, I'll take a pic and send it to mom."

"OK… But Jeremy invited us to the party today. Don't you remember?"

"Of course, I… WHAT? Oh no, I forgot because of those annoying little brats! But hey… I have a plan."

Candace took a video camera, plugged it in, inserted a memory card and was setting something.

"OK," Candace said. "The camcorder is powered by the electricity so the battery will never die. Additionally, I inserted a memory card with a huge storage and I switched off the HD mode so that I can record more. Apparently, I'll be able to record a 10-hour long video!"

Candace put the camcorder on the windowsill. She made sure that she could see the backyard in the lens.

"This time I should succeed," Candace smiled diabolically. "Mom will know everything and they'll be SOOO BUSTED!"

"OK, Stace, we can go," she told her friend. "I only have to change clothes."

"I'll help you choose the best clothes!" Stacy suggested.

Soon the girls went out of the house and started walking towards the place in which the party was supposed to take place. Candace noticed some trucks in the backyard.

"Everything will be recorded. And they'll be so busted!" Candace smiled to her thoughts.

The content of the last truck was in the backyard and Phineas was signing the confirmation of the delivery's arrival.

"Aren't you a little young to do such things?" the delivery guy asked him unemotionally.

"Yes, yes I am," Phineas answered simply.

Soon the trucks were gone and Phineas noticed a girl dressed like a Fireside Girl. She seemed to be in Isabella's age but he had seen her for the first time. Her hair was brown, she had a big ponytail and looked shy. The boy approached her.

"Hi," he greeted her with a smile. He was always nice to people. "Are you a new Fireside Girl in Isabella Garcia-Shapiro's troop? We were waiting for you. Come on, you'll help us. By the way, my name is Phineas. And yours…?"

"Hi, Phineas, I'm Emily," the girl responded shyly.

Suddenly, two weird reddish rays hit Phineas and Emily.

I hope it wasn't too horrible XD You know, it was my first story. I think that I should be able to upload the 2nd chapter tomorrow c:
