Welcome to my first fan fiction. Besides school assignments, this is my first story I've written. Please feel free to review. Constructive criticism is greatly appreciated.

Chapter 1

Another day of summer began at the Flynn - Fletcher household. For step - brothers Phineas Flynn and Ferb Fletcher, summer was the best time of the year. School would usually restrict their big ideas that Phineas would come up with every day. Now that school was over, it was as if they could relax, building insane inventions their way of relaxing. Their previous summers were full of awesome machines and contraptions for some reason annoyed their older sister, Candace. All summer long, she would try to 'bust' them to their mother but it would never come to fruition. However, this summer, at least the first two weeks, would be different.

"Boys", their mother called from the kitchen, "Candace is going away with the Johnsons for two weeks, so while I'm away at the store, dad's in charge".

"No problem mom!" Phineas replied, still as enthusiastic sounding as ever.

"Remember, once I've dropped off the groceries, I'll be getting dressed to go out with Isabella's mom tonight. Stay out of trouble." She said knowing that her boys would never get into trouble.

"We Won't!" It made him happy when she called Lawrence 'Dad'. While Lawrence was not his real dad, he was happy to accept him as his father unlike other people he knew from school. As he walked into the backyard, the sun broke through the clouds, as if to say summer was ready for him and vice – versa. Phineas then turned his attention to the big oak tree which stood in their backyard. Under it was his step – brother, the man of action himself, Ferb. Lying down beside his feet, in a deep sleep, was their pet platypus, Perry. No matter how bad things got, Perry always seemed to make it better. It was as if he was smarter than his appearance would suggest. Whenever Perry was around Phineas would always get an urge to sing, although about what, he was not sure.

"Hey bro", Phineas called to his brother. Ferb seemed to be daydreaming, his phone lying in his lap, stuck on a particular someone in his contact list. "Ferb?" Ferb unbroken from his trace continued to look skyward. Phineas sat down beside him and gave him a small punch on his shoulder. At first Ferb seemed startled but quickly returned to his relaxed demeanor.

"Sorry Phineas. I was just thinking", he said, begging to trail off.

"About what?"

"Do you think I should call her?" the green haired boy asked turning to his brother.

"Call who?" Phineas asked, totally clueless and not for the first time.

"Vanessa. Do you think I should call her?" he said in a serious tone. If there was anything he was serious about, it was his family, friends and Vanessa.

"Vanessa? Who's…? Oh, that girl from when we flew around the world during the summer solstice. Didn't she have a weird last name like Dichven…? Dooshels…?"

"Doofenshmirtz", Ferb responded flatly.

"Sorry, sorry" he replied. "Well, do you have a reason not to call her?"

"Well", he began, "I want to do something with her like go to the park, or the cinemas but…" he paused. "But I don't know whether she likes me."

"Are you kidding Ferb? Why wouldn't she like you?"

"It's not so much like as it is…" Ferb had to gulp before his last word came out as he knew how oblivious Phineas was to it. "…Love"

"Huh" was the red head's only reply but the cogs in his mind slowly began turning. "Ferb, what is love? I mean there are all different kinds of love and they come from different places. Like Mom and Dad, Candace and Jeremy, you and Vanessa I suppose and then there's me and…" Ferb began to hold his breath. Had it taken him this long to notice his feelings towards the girl across the street?

"Well, I suppose I love Perry but, we both do". He began to chuckle to himself as Ferb mentally face palmed himself. As he was doing this, Phineas' eyes began to grow wider as his impulses soon kicked in. "Hey Ferb! I know what we're gonna do today!"

Just then, the garden fence swung open as a cute raven haired girl bust into their backyard, the pink bow in her hair blowing gently as she pranced into view.

"Hey Phineas, What'cha doin'?" the girl said as she batted her eyelashes and exposed her big and deep sapphire eyes in an attempt to look even cuter. She wouldn't have to do this if she wanted to impress anyone else but Phineas Flynn was not just anyone. From the moment she laid eyes on him, she knew that this young boy would be her husband someday. But as she began her never ending quest to 'open his eyes', she realised that it would have to take everything she had for Phineas to open up to her.

"Hey Isabella!" he said getting to his feet. "We're gonna discover what love is and then find out everyone's true love." In the moment the word 'love' escaped from his mouth, Isabella's heart skipped a beat, many beats in fact.

"Did you say love" she asked calmly, wondering if she had misheard him.

"Yeah, it's all about finding out what makes you love something" Ferb replied.

"Or someone" Phineas said, looking at Isabella with a look on his face that she interpreted as flirting. Suddenly her checks flushed red by the idea that today could be the day she had been waiting for her entire life. She quickly realised that Phineas was looking at her with a confused look on his face and she desperately needed a distraction.

"Hey, where's Perry?" she asked nervously. Both Phineas and Ferb looked around as their pet platypus had disappeared once again leaving only a downtrodden patch of grass on the ground where he was sleeping.

Doofenshmirtz Evil Incorporated!

"…and that is why, Perry the Platypus, you cannot stop me from taking over the entire TRI-STATE AREA!" Perry, who was tied to a metal chair by a series of metal bars, looked at the evil Dr. Doofenshrmirtz with a puzzled look on his face, as if he didn't hear most of his speech.

"What? Why are you looking at me like that Perry the Platypus?" Perry chattered at Dr. D in response but he knew full well that Doofenshrmirtz couldn't understand him or only got the jest of what he was saying. "You want me to explain it again? You know you… you are not a good listener Perry the Platypus. There, I said it, you happy now?" Perry, in response tried to wriggle out of the trap he had been caught in not minutes ago. "Oh, and don't try to escape. Those bars are made out of the same material I made Norm out of and trust me…" he chuckled to himself "…they are pretty durable." Just then a metallic looking head poked out from out of a door from the opposite side of the room.

"Did you say I can come out now, Dad?" the robot replied in an upbeat American dream dad voice. Doofenshmirtz began to shudder and turned his back towards Perry.

"Norm, what did I say about calling me that? It just… egh… creeps me out. I hate it when you call me Dad or father or any kind of parental title. Now get back in the closet!

"Okay, Daaaaad!" Norm said in a mocking tone going back into the closet. Doofenshmirtz began to mutter to himself, probably wondering why he kept Norm around.

"I'm sorry about that Perry the platypus it's just I can never think of Norm as anything else as just a failed invention that never got rid of you." Dr. D was getting off topic, something he did a lot but it only took Perry's chatter to get him back on track. "Oh right, my evil scheme, but first. Backstory Time!" he said in a singsong voice. "Long ago, like a week or something, after you foiled another one of my evil schemes, I had to catch the bus seeing as you caused me to fly off my building in a huge explosion for like the tenth time this month. I mean seriously what is wrong with you. It's a miracle I'm not pushing up daisies or whatever the evil counterpart to a daisy is. Anyway, I was just about to catch the next bus, when this hip young teenager shoved me out of the way. I think I might have seen him with Vanessa once. But as I fell into the street he yelled out "The early bird catches the worm". Oh I cannot tell you how much this infuriated me, seeing a younger, more successful person get more than me, in this case, the bus. So when I eventually got back home, I looked up this phrase and it turns out that it has nothing to do with birds or worms, I think." During his evil ranting, he had no idea that Perry was asleep, obviously bored within an inch of his life. "…It turns out that if you get up early enough, you get what you want, or something like that and so now I present to you..." He picked up a big sheet that he had used to reveal his invention before and put it back on this new weapon before taking it off again. "Behold, the Earlybirdgetstheworm-inator!" He yelled with the upmost confidence in his inator. Perry was still asleep.
