It appears that our London trip is being pushed back yet again... but that just means more chapters until this story's done! Enjoy!

Disclaimer: I don't own Phineas and Ferb- that is owned by Dan Povenmire and Jeff "Swampy" Marsh!

Phineas ran to the garage to grab his huge box of drills, wrenches, screwdrivers, hammers, nails, rivets, and much much more, and grinned as he carried them out.

"Are you all ready to do this?" he asked, and the group cheered. "Let's start then!"

He grabbed various parts out of the pile of metal that Paul had just dropped off. "Okay, so what this device does is take us to a day in the past and we pretty much get to relive a day as that age. I'm still not sure what to call it, though. Ferb?" Phineas inquired.

Ferb squinted in thought, and then raised his finger with an idea. "How about-" he started, but was cut off.

"Wait, I have an idea! Let's call it the Past Blaster! Like, as in 'blast from the past'... do you get what I'm saying?" Phineas tried to explain.

Ferb sighed and facepalmed, and Emma giggled at his expression. "It's okay, I'll call it your name." she winked, and he blushed.

"What are you standing around for? We have to get this done if we want to go on the rollercoaster!" Phineas exclaimed and threw his hands in the air. He grabbed a drill, some screws, and a few pieces of metal and started to put them together.

"Umm... Phineas, blueprints?" Isabella inquired. Phineas looked up at her.

"What about them? Oh! Sorry about that!" he laughed and set up their drawing board and the blueprints.

Emma wasn't quite sure what to do, so she just went with Ferb and handed him tools when he needed them.

"Monkey wrench?" Ferb asked first.

Emma looked around. "Um... what's the difference?" she asked with a slight blush.

Ferb slid out from under his project. Emma couldn't help but laugh at the motor oil stains he had on his face.

"You got a little..." she started, kneeling down. She licked her finger and wiped it off of his face. "There ya go!"

"Thanks..." he chuckled. "Anyways, I suppose I should tell you what tools we have before asking you for them, huh?"

"That would probably be a good idea."

Ferb laughed and started telling her what the tools' names were and what they did.

Over on the other side of the yard, Buford was making fun of Baljeet while he held up a huge chunk of metal while Phineas welded it together.

"Um, Phineas?" Baljeet whimpered, his thin, spaghetti-like arms starting to buckle under the weight.

"Yeah?" Phineas asked, flipping up his welding mask.

"I-I don't think I can hold this for much longer."

"Oh, that's okay! I just remembered I have a ladder we can put under it. I thought you just wanted to hold it!" Phineas offered.

"You- you had a LADDER?" Baljeet screamed.

"Well, yeah! Who doesn't have a ladder? What do you think we did when you and Buford weren't here?" Phineas scoffed. "Hey, Isabella!"

Isabella glanced up from her part of the work. She was wiring the mainframe and Buford was supposed to be helping her, but he was busy making fun of Baljeet.

"What's up?" she asked.

"Can you grab the ladder from the garage, please?" Phineas asked with a grin.

"Phineas... I'm kind of in the middle of something here." she replied, faking an indifferent face, mocking him for the first time they had built a roller coaster and he completely brushed her off.

"Hey! How many times have I apologized for that? I didn't mean to sound like a jerk!" he laughed.

"Oh, I'm just kidding! But really, I'm kind of at an important part. Can't Buford get it?"

Phineas looked at Buford. "You have to do something, you know?"

Buford crossed his arms. "You can't tell me what to do, Dinnerbell!"

Phineas gave him a sassy look. "Buford... do you want me to go get Little Suzy?"

"NO, NO, PLEASE NO!" he screamed and ran to the garage to grab the ladder. The other three cracked up at their friend's reaction to even the mention of Jeremy's little sister.

Emma and Ferb looked up from their tool lesson to see Buford scrambling to the other side of the yard with the ladder. Ferb chuckled and shook his head. "...anyways, this is a..."

All of a sudden, time started going faster as a montage started. The Quirky Worky Song played in the background and within a few seconds, the machine was all put together.

"Well, that was fast!" Phineas said, wiping the sweat off of his brow. The others nodded and looked at the huge chamber. "Are you all ready to be 9 again?"

Emma grabbed Ferb's hand. "I can't wait to meet little Ferb!"

"And I can't wait to meet little Emma." he smiled and gave her hand a squeeze. The group stepped into the chamber.

"Okay, Ferb! Let's fire this baby up!" Phineas said, and Ferb pulled a red lever. They felt themselves spinning rapidly, the walls lighting up with a white light streaked with blues and purples. Seconds later, they stopped spinning.

Emma held her forehead and groaned. "Ouch..." she said in a higher pitch than usual. She gasped and looked down. Yep, I'm definitely a kid again... she said, finding herself wearing her old childhood outfit. She was wearing a blue, white, and teal striped sundress with blue shoes. What was even more surprising to her was the kid standing in front of her.

She looked up to find a younger version of Ferb. He was wearing a yellow polo, similar to the one he wore back in real time, but he had on strapless purple overalls with a purple belt, white socks, and black shoes.

"AWWWWW! FERB!" she giggled, covering her mouth with her hand.

Ferb blushed, rolled his eyes, and sighed. "Oh, shush. I don't even look that different. Look at yourself!"

She blushed with him and took the sides of her dress in her hands. "Thank you..."

Ferb offered Emma his hand with a small bow and she took it happily and they walked out.

Phineas, Isabella, Buford, and Baljeet were already outside, looking in awe at the other group of kids that were staring at them. The other Ferb jumped at the sight of another him holding hands with a girl he had not seen before.

"W-who are you?" the other Phineas asked.

"We're you from the future!" Phineas replied excitedly. "Can you believe you did this, Phineas?"

The other teenagers (in kid form) cleared their throats.

"Sorry, you ALL did this!" Phineas clarified, finally gaining the approval of his friends.

(From now on, our original cast will be known as their regular names and our new characters will be known as kid [insert name])

"So... how'd you guys get here, and why?" kid Phineas asked.

All of a sudden, kid Isabella piped up. "Um... are you guys like the ACTUAL future for us?"

Phineas looked at Ferb, who looked deep in thought. Kid Ferb was still directly staring confusedly at the intertwined hands of him and a random girl. He looked like he wanted to say something, but Ferb gave him a wink and mouthed the words, 'I'll tell you later.' Kid Ferb saw this and breathed out shakily but flashed him a thumbs up.

"Well, honestly, we're not sure what's going on. Wait, what are you guys doing today?" Phineas asked.

"Ferb and I are building a rollercoaster! Isabella just showed up. By the way, who are those two? I haven't seen them before." Kid Phineas asked, pointing to Buford and Baljeet.

"Oh, that's right! You haven't met them yet! Just wait a week or so." Phineas replied.

Kid Isabella looked at Isabella and her eyes darted to Phineas and then back to Isabella. Isabella knew exactly what she was trying to say, and she gave her a smile and grabbed Phineas' hand.

"You okay, Izzy?" Phineas asked, looking at the girl who just grabbed his hand. Kid Phineas just stared in shock.

"Yeah! I love you!" she giggled. Phineas looked at her with a smile.

"I love you too..." he said, and then his gaze returned to Kid Phineas.

"W-w-what just happened?" Kid Phineas asked, his face turning bright red. He turned to look at kid Isabella, who was wearing the biggest grin he had ever seen in his life. She saw him look at her and slapped herself.

"What? I'm totally cool!" she said, and then turned the other way and celebrated to herself again.

All of a sudden, a large metal clank was heard from behind them. Phineas spun around and his jaw dropped when he saw what had just happened.

"No... that was our way home..." he said quietly.

The whole structure had fallen apart into a pile of metal and bolts.

Ferb looked at Buford, who was fidgeting with something. He gave Buford a death stare, and Buford whimpered as he opened his hand.


Kid Ferb looked in shock at the other Ferb's reaction. Phineas and Isabella stood in shock too.

"Whoa, Ferb... you've changed." Phineas said quietly, and the three kids couldn't help but snicker, but stopped when Ferb turned back around to face them. He sighed deeply and walked up to them.

"Okay. We're going to need your help to fix this. Think you can help us?" he asked.

Kid Phineas and Kid Ferb nodded.

"We're gonna need a lot more peanut butter, Ferb." Kid Phineas said, and the whole gang laughed at his comment.

Phineas looked at the pile of metal, the three kids from this reality, and his friends. He inhaled deeply before coming up with a plan.

"Alright... both of you Ferb's are great at the mechanical stuff, so you two, and Emma, will work on trying to put this back together. Me and the other Phineas will work on these blueprints and programming, and Isabella's, you two can work on wiring again." Phineas commanded the groups of kids, but then remembered the other two boys. "Buford and Baljeet... you can help me and Phineas with our tasks."

Everyone split up into their groups and suddenly, something very weird happened. The original gang flickered and turned back into their teenage bodies.

"Whoa! What just happened?" Isabella asked, as she watched herself become taller, curvier, and much, much more beautiful.

Phineas grumbled. "I guess the age difference thing wore off. It's okay, I think with our teenage bodies, we will be more able to lift stuff. No offense."

The kids nodded and admired their grown forms.

"We're so... pretty!" Kid Isabella cooed at her older self, and Isabella laughed. "So... about Phineas! You have to tell me everything!"

Isabella grinned at her childlike self and started telling her the stories of her and Phineas when they finally got together. Kid Isabella sat there on the ground with her arms around her legs, her pupils forming hearts, and a smile on her face.

Phineas and Kid Phineas were busy working on their blueprints while Buford and Baljeet messed around.

"So, what I was thinking-" Phineas started.

"-was that we need to figure out the main frame-" Kid Phineas continued.

"-so that we can get everything right, yes, exactly! Oh, man, I need a mini-me back home." Phineas chuckled and gave himself a noogie. "So... eyes on any girls?" he winked.

"Uh... girls? What about them?" Kid Phineas asked with a confused look.

Phineas facepalmed. "Oh, you just wait a couple years... you'll get there."

"About that! Why were you holding hands with Isabella? And you guys must be amazing friends!" Kid Phineas smiled.

"Uh... yeah, friends is an understatement. Isabe-" he started, but then thought he would mess up a timeline if he told him.

"What?" Kid Phineas asked.

Phineas sighed. "Just some advice. Don't ignore all the signs. There's someone out there that loves you very much, and you can't let her go. She's perfect, and she will love you no matter what. Don't mess it up like I almost did, kid."

Kid Phineas raised an eyebrow. "Who is it?"

"I can't tell you, but I can tell you to be more alert for signs that someone likes you." Phineas smiled sadly.

Over by the pile of parts, Kid Ferb was helping Ferb build up the frame.

"Hand me the-" Ferb started.

"You need the rivet gun." Kid Ferb smiled and held out the tool for him.

"Atta boy!" Ferb grinned and kid Ferb flashed him a thumbs up. Emma giggled at the spectacle happening.

"So, Ferb! Got eyes on any girls?" she asked, leaning her arm on Ferb's back.

Ferb looked at her. She's so pretty... Where can I meet a girl like that? Vanessa is nothing compared to her... he zoned out and Ferb chuckled, knowing that look all too well.

"Hey, kid. Wait your turn!" Ferb laughed and noticed as kid Ferb's face started turning bright red, spreading from his cheeks to his nose and then up to his forehead. "You'll find her someday, I promise. Give it a few years. She will be worth the wait." he said as he turned around to put in a couple rivets. When he turned around, kid Ferb took his shot and winked at her. She giggled and covered her face with her hand, then leaned down and kissed him on the cheek. His face turned even redder and he almost fell over.

Ferb turned around to see the kid version of himself red as an apple. He chuckled and turned to Emma, who was smiling at both of them.

"This would be disturbing if I didn't know what was going on." Emma giggled, and the two Ferb's exchanged a glance, as if they were communicating non-verbally. Ferb held up 3 fingers and silently counted down, and then on the count of three, both of them kissed each of her cheeks. She turned red at the silly exchange.

"Wow, now I have to decide between two Ferb's? Sorry, Ferb... I think the younger you's cuter." she grinned jokingly as she pulled kid Ferb into a hug. All of a sudden, kid Ferb kissed her on the lips. Her eyes widened and she pulled away.

"HEY! That's MY girlfriend!" Ferb laughed as kid Ferb shrugged with a mischievous grin on his face.

A few hours later, all the groups had finished their separate tasks and just needed to combine everything and get back home. Phineas and Ferb had lugged over the mainframe and started to wire everything up to the physical frame while Emma, Isabella, Buford, and Baljeet made sure everything was in place.

"Buford, all we need is that one piece you had!" Emma said, looking up at Buford.

He shrugged. "What piece?"

Her face turned worried, and Phineas and Ferb's eyes darted over to the other group. "Buford... where did you put it?" Phineas asked calmly, hoping he had misheard something.

"Uh... I don't have it! I accidentally dropped it in the grate outside..." Buford said sadly.

Ferb facepalmed, and was about to blow up on him again when Emma rushed over to him and pulled him into an embrace.

"Phineas, can you handle this? He's stressing out!" Emma begged as she held Ferb. Kid Ferb very much wished he was older. He would win Emma over if it was the last thing he did.

"Yeah, I got it..." Phineas sighed and walked over to Buford. "You dropped it... in a grate?" he asked, trying not to scream.

"Yeah. I was over by the front of the house and it fell down the drain." Buford shrugged.

Ferb's head shot up from Emma's shoulder and he pushed her away.

"Buford... did you NOT hear the entire SPIEL about that being the ONLY thing we needed to get HOME?" he said angrily, balling up his fists. "I would think that after one time of getting mad at you, you would keep the DAMN THING SAFE!"

Buford shuddered as Ferb reached his ultimate wrath mode. The kids cowered behind their grown up versions, (Ferb behind Emma obviously), as Ferb continued to yell at Buford.


Buford puffed out his chest trying to rebuke the intimidating green-haired monster, but all it did was make Ferb even more mad.

"Don't you dare try to defend yourself. I'm not going to hurt you, I'm going to go sit in this corner and pretend you didn't just cost us possibly our lives. Did I forget to mention that if we don't get out of here in 24 hours, we will be permanently stuck in this dimension?"

Phineas walked up to his brother and put his hand on his shoulder.

"PHINEAS! Get your hands off of me! I was supposed to take Emma to homecoming. I was supposed to go to London for high school. I was supposed to get accepted into some crazy college, and now that's screwed up because this nitwit decided to drop the one thing we needed INTO A GRATE!" Ferb screamed, his face becoming redder and sweatier by the second. Emma took kid Ferb by Isabella and told him to wait there. She walked up to her boyfriend and turned him around.

"Ferb Fletcher. I do not care how mad you are. We don't talk to our friends like that."


"Don't you dare interrupt me. We will figure this out, and screaming at him is not going to help this. The longer you spend yelling at Buford, the shorter time we have to get the piece from the grate."

Ferb was brought out of his anger by her soft but firm face. Her soft lips moved perfectly with every word she spoke. Her words became gibberish as he focused on her soft facial features. Her small, slightly pointed nose reminded him of a button. Her huge, hazel eyes sparkled in the sunlight that was slowly fading. He couldn't help himself.

"Use your brain, Ferb. I know you're smart. I'm telling you this because I love you. Get yours-" she said, but was cut off by lips on hers, the passion flowing through them like molten lava.

He pulled her in rapidly, forgetting that there were other people here. Ferb's hands moved down her back, landing on her hips. He pulled her up, lifting her off her feet slightly.

"EWWW!" the three kids yelled, and it woke the kissing couple up from their little wonderland.

Ferb pulled away. "S-sorry... you're cute when you're mad."

Emma rolled her eyes. "I think you need to apologize to Buford, not me." she said as she turned to face Buford. "It's not all sunshine and rainbows for you, either. You need to help us find that piece so we can get home."

"Can I get out of your anger with a kiss too?" Buford smirked, and Ferb shot him a glare that said 'you touch her and I will personally kill you'. He put his hands up in defense. "I was kidding, jeez!"

Phineas walked up to the tense two and looked at them both. "Okay, okay. First, we need to figure out how to get that part back, or figure out how to get a new one. Ferb, where would it be by now?"

Ferb shook his head. "If he dropped it, it's long gone by now."

Phineas exhaled and looked at Isabella with a sad glance. "Phineas, you're coming with me. We're gonna go find that piece." he said, motioning the kid Phineas to come along with him as they walked out of the backyard.

"Come on, I'll show you my, well, our, favorite place for parts!" Kid Phineas said, running along the sidewalk down the street. Phineas knew what he was talking about, but decided to let the kid have a little bit of a hero moment, so he just followed along.

"So... what does this piece look like?" Kid Phineas inquired as they reached the hardware store.

"It's a little microchip that has a switch on it. It basically works as a restraining bolt and a main storage chip that keeps the whole thing functioning. Without that, we can't get home." Phineas explained, and kid Phineas smiled and nodded.

"If any two people can find this, it's gonna be us." Kid Phineas grinned and took Phineas' hand as they ran through aisles looking for it.
