(Author Note)

Thanks for the reviews on my last stories. This is another request from WordNerb93 and I was happy to write this. I hope you all enjoy this story as much as I am enjoying writing it.

P.S. I know they are really young but they can carry out conversations hahaha intelligent ones. Ok I'm done.

(Flynn-Fletcher back yard 5 years earlier)

"I love you Perry" six year old Phineas said as he picked up Perry and hugged him

"Grrrrrr" Perry chattered back

"Hahaha" Phineas and Perry both turned their heads towards the sound of laughter.

A small girl poked her head, followed by the rest of her, into the back yard through the open gate. She had a small pink bow tied neatly in her raven black hair. She wore a small pink shirt with a red heart on it and some jeans. Her eyes were a pretty shade of purple; they glanced around the back yard but always came to rest on young Phineas. Isabella slowly made her way through the gate and was standing on the edge of the back yard just staring.

"Come in" Phineas put Perry down and got up to meet her "I'm Phineas" He said as he met her half way

"I'm…Isa…Isabella" Isabella blushed as she rocked back and forth on her heels

Phineas couldn't help but notice how cute she was. Her face was lit up as if she was being illuminated by heaven itself. Her movements flowed into one another as she rocked back and forth. Phineas could feel a slight blush forming on his face as he realized he was starring; even though he was young he was very intelligent. In order to side track himself he decided he needed to say something.

"I…I like your clothes" Phineas truly liked everything about her but he thought this would be less obvious

"I don't" Isabella stopped rocking and looked down on her outfit with an obvious frown "My mom made me wear it over here. I wanted to wear my pink dress" Isabella gave her clothes one last frown before returning her gaze to her new friend

"Why did she make you wear that if you didn't want to?" Phineas was curious why someone would make their kid dress up in something that they didn't want to dress in

"Because we just moved in across the street and she said I looked better in this then my favorite dress" Isabella looked a little upset explaining this

"You're our new neighbours?" Phineas forgot his mom mentioned they had new neighbours and a potential new friend for him and his step brother Ferb

"Yeah, my mom wanted to come over and say hi. You're mom said you were out back with your pet. I thought you might have a dog like me but I see you have a…"Isabella looked Perry over and gave an obvious confused look to Phineas that said she didn't know what he was

"Oh this is Perry our pet Platypus" Phineas bent down and grabbed Perry "You can pet him" Phineas held Perry out

Isabella slowly reached her hand out and let Perry sniff her, like she did with her dog when she first got him. After a few seconds Isabella started petting Perry and her initial stress had dissolved.

"So it's just you and your mom living here?" Isabella questioned as she kept petting Perry.

"No my brother and dad are out right now. You'll love my brother. His name is Ferb" Phineas started getting excited thinking about everything they could do with their new friend.

"That's cool" Isabella said

"You know Isabella…I know I just met you but I really" Phineas was cut short

"Isa, it's time to go. We have a lot of unpacking to do" Isabella's mom poked her head into the back yard through the back door

"Ok mommy" Isabella started running to the front of the house waving a final good bye to Phineas as she slipped through the gate.

"Like you" Phineas finished "I'll tell her tomorrow, right Perry?" Phineas started walking towards the back door.

(Present day)

"See you guys tomorrow" Phineas and Ferb waved as Isabella, Buford and Baljeet exited the back yard.

It had been a fun day with their friends but something kept nagging at Phineas that he was forgetting something. He shrugged it off as the two retired inside for some dinner.

Through the whole meal Phineas still couldn't shake the fact that he had forgotten something. He pushed it out of his head and quickly finished dinner and retired to his room. Ferb soon joined him.

As Ferb entered the room he saw Phineas sprawled out across his bed with multiple blueprints spread out. Ferb, being the keen observer he was, knew instantly Phineas was trying to forget or remember something. He had observed Phineas for years and this was the one and only thing he could not figure out just by observing, he felt it was time he just asked.

"What are you trying to remember?" Ferb entered the room making a B-Line for his bed. If Phineas didn't want to talk at least he could make it look like casual conversation rather than prying.

"How did you know?" Phineas was curious and a little ashamed. He was a genius how could he forget something?

Ferb just shrugged and got a book. Phineas knew he was telling him to continue and he decided that it might be time to ask for help, and who better to ask then your genius brother?

"I honestly don't know Ferb. I always get this nagging sensation that I am forgetting something. I've been able to avoid thinking about it by focusing on tomorrow and what we can do then. It's just so annoying because I feel it is something I should have done a long time ago. I just don't know" Phineas went back to looking through his blueprints.

Phineas noticed Ferb had kept quiet and thought he must be as stumped as him. Normally trying to find something new to do tomorrow was exciting and fun but at this moment all it did was make Phineas frustrated. None of the designs were even close to interesting and he didn't feel up to creating new ones at the moment. He was about to ask Ferb for help when he noticed Ferb sketching something onto an old blueprint.

"What are you doing?" Phineas asked curious as to what his brother had come up with. Ferb didn't respond he just kept sketching and making changes to whatever it was he was creating.

"Alright let me know when you're done" Phineas turned his attention back to the pile of blueprints. He knew he wouldn't find anything tonight but was hoping something might jump off the pages and really inspire him. Then a rolled up piece of paper hit him square in the head. Phineas quickly unrolled it and looked over Ferb's design. A smile grew on his face.

"A machine to bring out cloudy memories, Ferb you're a genius" Phineas rushed his brother and tackled him in a hug. Ferb smiled as Phineas hugged him tight. He knew, even if Phineas wouldn't admit it, that this was really bugging him.

Phineas prolonged his affection as long as he could until he decided he got his point across. Phineas finally broke his hug and returned to his bed ready for a night of rest.

"Thanks Ferb, now I'll be able to sleep knowing this burden will be off my shoulders tomorrow" Ferb just gave him a thumb up before turning out the lights and falling asleep.

Phineas however couldn't sleep as his mind started filling with ideas of what this memory could be. Was it something he didn't really need to remember, something that could tear him apart, something that could bring him closer with everyone…his mind kept coming up with new scenarios of what he might find.

He spent most of the night lying in bed awake. His eyes closed and his mind full.

(Flynn-Fletcher backyard – next day)

"Hey dinner bell" Buford said as he opened the backyard gate with Baljeet's head

"Hey Buford, where's Isabella?" Phineas noticed she was late for today's activity.

"How should I know?" Buford dropped Baljeet

"What about you Baljeet?" Phineas directed the same question to his Indian friend

"I have been with Buford all day. I haven't seen her since yesterday" Baljeet responded as he got to his feet

"Maybe she slept in. Anyway todays invention is designed to help me recover a memory" Phineas looked up and saw Buford needed more information. "I have been having a feeling of forgetting something, so Ferb designed this little gadget to help me remember. I hope this works because I want to get back to having fun." Phineas was happy to see Buford got the gist of it

"What can we do?" Baljeet offered

"How about helping Ferb with the computer code and Buford you can help me hammer these pieces together"

"I like to hit things" Buford went to help as Baljeet made his way over to Ferb.

Phineas held two pieces of metal together as Buford hammered them into place. Phineas was praying Buford wouldn't miss; the look on his face also scared him. Buford seemed too happy just hammering the pieces into place. Phineas was focusing so much on Buford that he didn't even hear the back gate swing open.

"Hey Phineas, Whacha Doin?" Isabella strolled in

"Hey Isabella we were just" Phineas stopped as he looked at Isabella. "Isa…Bella" Phineas repeated slowly

"Oh yeah. Sorry about my clothes. I forgot to do laundry last night and didn't have any clean dresses to wear. This was all I had" Isabella looked down at her clothes with an obvious frown on. She didn't even see Phineas's eyes light up.

Phineas was over joyed at what Isabella was wearing. She had her trademark bow tied into her raven black hair and a bright pink T-Shirt with jeans. The pink T-shirt was plain and didn't have any designs on it. The reason this was a big deal was because Phineas's mind started flooding back to when they first met, all those years ago. He remembered that day like it was yesterday. He remembered what he wanted to say to her. Phineas smiled.

"Ferb you can stop now. I remember" Phineas stood up and started walking towards Isabella

Ferb, Baljeet and Buford stopped and stared at Phineas with curiosity in their eyes. They were wondering what he remembered.

"Phineas? Is something wrong?" Isabella was concerned by the look in his eyes. She had never seen this look before and didn't know what to expect.

"Isabella I have something I have to tell you" Phineas smiled even wider
