Hello! Welcome to my Phineas and Ferb fanfiction where the gang faces their most difficult challenge yet - high school! This fanfiction will start on their first day and end at Act your Age.Just a few things to make clear:

1. What all the characters are doing

-Phineas, Ferb, Isabella, Buford: high school

-Candace, Stacy, Baljeet, Jeremy: collage

-Vanessa, Irving: interning at OWCA

-Monogram: preparing for retirement

-Carl: taking on the role of commander

-Perry: retired from the crime fighting life, although ready to return at a moments notice

-Doofenshmirtz: finishing out his career as a science teacher

2. This series is revolving around the kids in high school, so we will see very little of Perry, Candace, Carl, etc.

3. I'm not counting Night if the Living Pharmasists as cannon. I may reference it a few times, but even though the creators have said it's cannon, for the sake of this story I'm leaving it out.

4. I do most of my writing from my phone, so the formatting may be a little off.

5.I understand that neither me nor my writing is perfect. If there's a mistake or you have a suggestion, I will not get offended if you let me know. (Unless you're a hater. No haters please)

Now let's get started!


Phineas woke up as his alarm beeped loudly. His step brother Ferb reached over to shut it off. As Phineas sat up and stretched, a chattering noise alerted him of the small, semi-aquatic mammal sitting on his bed. "Hello, Perry," He said, scratching the
/little guy on his head.

"So, it's off to high school now," Phineas said as he climbed out of bed. Strolling past his Space Adventure poster, he opened the closet to reveal a variety of shirts. "Hey, Ferb, remember when we were kids and wore practically the same thing
every

day?" Ferb nodded. Although he talked more than he did in grade school, he still preferred to let Phineas do most of the chatting. "Well, it can't hurt to go with our signature looks for the first day," he said, pulling an orange shirt over his head.
/As Ferb buttoned up his purple pants, the two headed downstairs.

"Hi, boys," said Linda as they walked into the kitchen. "Hi, mom" said Phineas. He and Ferb sat down at the table as Linda put down some cereal for them. "So, are you excited for high school?" Lawrence asked. "Yeah we are!" Phineas exclaimed excitedly.
/Ferb blinked in agreement. "Hey, where's Perry?" Asked Lawrence. "Oh, he's still upstairs, the little sleepyhead," said Phineas between mouthfuls of crunchy corn flakes.

"Bye, mom! Bye, Dad!" Phineas said as he pulled the door shut behind him. Together, he and Ferb began their walk toward Danville High. "Hey, Ferb, I think today is gonna be a great day."


Isabella tied her hair back in a braid, ready to start her first day of high school. She smoothed out her pink shirt and tightened her hair bow, determined to look her best. She looked around her room, her last time there before high school. Her pink
/comforter was nicely laid over her white bed, the fuzzy rug was currently hosting her chihuahua, Pinky, and photographs on her bedside table. Smiling at the memories they all brought, she picked the center one up. It was a photo of her and all her
friends

when they were eight. Buford, the neighborhood tough guy, was standing by Bajeet, giving him a noogie. Buford couldn't leave Bajeet alone long enough to take a photo, she thought, smiling to herself. In the photo there were also two boys and
a girl,

arms around each other, smiling and laughing. On the right was Ferb, the silent boy from across the street, on the left was herself, smiling and looking shyly at the boy in the middle, her best friend and lifelong crush, Phineas.

No. Not crush. Best friend, yes. But Isabella had resolved to get over this silly crush and just be his best friend. She put the photo down beside the picture of her and her mom at the park, her seventh grade soccer team (they had won the regional championship),
/and her fireside girls troup graduation. Now that she was too old to be a fireside girl, she found other ways to continue the joy she had felt as a trouper. This summer, she was a junior consular at Camp Fireside. It was so fun, helping all the eager
/little girls earn new patches. It was just like her when she was a kid.

"Good morning, Isabella," said her mother as she set down a plate of scrambled eggs for Isabella. "Hi mom. Thanks!" She said, chewing a mouthful of cheesy egg. "So, are you ready for high school? Hanging out with all your friends? Baljeet, Buford, Katie,
/Holly, Ginger, Ferb...Phineas?" Mrs. Garcia-Shapiro Asked, with a sing-song tone when she mentions Phineas. "Mom! I already told you. Bajeet is going to university, since he took all those high school classes over the summer. And I don't
like

Phineas anymore. He's my best friend, and we're both perfectly happy with that." "I know, Bella, I was only teasing," said Mrs. Garcia-Shapiro. "I know mom," said Isabella as she put her plate in the sink. "Well, id better be going. Bye mom!" "Goodbye
/Isa. I'm so proud of you!" "I'll see you after school!"

As Isabella walked out the door, she saw three boys at the end of the block. "Hi, guys," she said, running to catch up to Phineas, Ferb, and Buford. "Hi, Isabella. Whatcha doing?" Asked Phineas playfully. "Just walking to school. How about you?" "We were
/talking about what sports were playing. Ferb and I are playing soccer and baseball." "And I'm playing football," said Buford. "Real football, not your weird British football." "Actually, it's futbol, spelled with a u, more commonly know as soccer,"
/said Ferb. "It was called futbol because it was played on foot rather than equestrian.""Yeah, whatever," said Buford. "What about you, Isabella?" Asked Phineas. "Just soccer," isabella replied. "Hey, did you guys hear about the new milkshake

shop that opened last week?" "Yeah!" Said Phineas. "We should go there after school! You know, to celebrate our first day of high school."

As they were talking, they walked up to Danville High. "Well, here we are," said Isabella. "Let's go get our lockers and class schedules."

At the registration...

"Let's see. Garcia-Shapiro, Isabella," said the lady at the recption table. "Here's your class schedule and lock. Your locker is number 83. Have a nice day! Next!" Isabella walked away, found her locker, and opened it. She put her textbooks and binders
/in neatly, and opened her backpack. She had brought some decorations - having the same locker as everyone else was boring. Pulling out the lime greenwallpaper with pink stars, she put it on her locker and proceeded to begin putting cute magnets
/and stickers on the outside. Inside she stuck a mini bulletinboard and finished off the decorations by pinning her Fireside Girls sash onto it. That sash was her pride and joy, a mark of all she had accomplished as a little girl.

"Isabella?" Said a voice. "Ginger!" Isabella said happily. "You have the locker next to me?" "Yup! Number 84," Said Ginger, opening her locker and stuffing her books inside. "What's your schedule look like?" "Well, let's see," said Isabella. "First period,
/Geometry. Second period, Biology. Third period, English. Fourth Period, art. Fifth period, history. Then lunch, then Spanish, then study hall." "Cool," said Ginger. "I have Science, then Algebra, Spanish, Study hall, History, Lunch, English, and then
/PE."

Chatting, the two girls continued to place textbooks and papers in their lockers. "It's going to be weird not having Baljeet with us," said Isabella. "I know!" Said Ginger, a little sadly. "Did you ever ask him out?" Inquired Isabella. "No," Ginger sighed.
/"Well, were going to the new milkshake shop after school. Maybe you can text him to meet us," said Isabella. "Speaking of asking people out," said Ginger, "are you going to ask out Phineas?" "No way!" Replied Isabella. "I've resolved to end this crush
/and just have fun in high school." "Isabella, I don't believe for one second you're over Phineas," Ginger said seriously. "You're right," said Isabella. "But these are my last four years before collage. And if I'm going to make good memories, then
/I want them to be with my friends, not with my oblivious crush." "C'mon, Isa," pushed Ginger. "You already know he thinks you're cute." "Ginger, he hasn't called me cute since we were eight. Besides, I don't even think he knew what cute ment. He's
/my best friend, and I don't want him to know I've been crushing on him." "Hey!" Said Ginger, pretending to be offended. "One of my best friends," isabella corrected. "Hey, I think I see Holly and Katie over there let's go check out their schedules"

"Flynn, Phineas. Fletcher, Ferb. Here are your schedules. Phineas, your locker is 97. Ferb, your locker is 98. Havea nice day."

"Alright!" Said Phineas, checking out their schedules. "We've got the exact same classes. Geometry, Biology, Study Hall, Robotics, English, History, Lunch, Spanish, Robotics." They dropped off their textbooks in their lockers and headed over to room
112,

the Geometry classroom. There were already a few kids in there: Adyson, from Isabella's old fireside girl troop, Django, another resident of Maple Drive who was a very talented artist, and a few other people they didn't recognize. Phineas and
Ferb

went to sit by Django. They knew each other pretty well: they hung out during summer break and when they were little they would play together while Candace hung out with his older sister Jenny. "Hi, Django," Phineas said as he set his backpack
down.

"How was your summer?" "It was great!" Django replied. "I got to go to this super cool art camp, and it really paid off! Look what I drew!"

He pulled a few drawings out of his binder. One was an almost exact replica of the Space Adventure poster hanging over Phineas's bed, another was a sketch of Django's Dad, and the final one was a pencil drawing of Perry. "This one is for you,"
said

Django, handing Ferb the drawing of Perry. "Thanks!" Said Phineas, while Ferb nodded his agreement. Slowly, more and more people trickled in, and Django saw one of his friends from art camp. "Phineas, Ferb, this is Sean. He went to art camp with
me.

Sean, these are my friends Phineas and Ferb. They like to build stuff." "Hey, Sean." "Hey guys."

As Django and Sean began to talk about an art project, Isabella walked in. "Hi, Isabella," Phineas and Adyson said at the same time. "Hey guys," said Isabella. Just then, the bell rang. "Alright, class," said their teacher, who had just walked in.
"My

name is Mrs. Roseki. Please take a seat." Phineas ended up sitting with Ferb on his left and Isabella on his right, with Django on Ferb's left and Adyson on Isabella's right. Mrs. Roseki wrote her name on the board, and then began to pass out
worksheets.

She had light brown shoulder-length hair and hazel eyes."Please open your books to page 5 and begin copying the terms into your notebook."

After Geometry...

"What class do you have next Isabella?" Phineas asked as they walked out of the classroom. "Biology," said Isabella. "Us too!" Phineas said. "C'mon, let's stop my our lockers and then head over there." After picking up their science textbooks, the
trio

met at the classroom and walked in. They were the first ones there, besides the teacher. He had a very pronounced chin and brown hair and was wearing a light green shirt with a purple tie and a lab coat. "Come on in," He said looking up as they
paused,

not sure if they should enter. "What was his accent? German?" Isabella whispered as they walked in. "I think it's Drusselsteinian," Phineas whispered back.

"Cool classroom," Phineas said as he looked around. Contrary to most labs, all white and with boring posters, the walls had been painted purplewith large greencircles all around, and little model inventions all labeled, "freeze-inator, growth-inator,
/clean-inator," and the likes. "You like it?" Said their teacher. "It was all boring when I first started teaching, and I couldn't stand it. So a few summers ago I painted it all and put in new tiles and stuff." "Do these work?" Phineas Asked,
indicating

the tiny inators on the shelves. "Oh, yeah," He said. "I used to make them much bigger, but the school thought that was unsafe and now I just make tiny ones. The clean-inator has been amazing for cleaning up lab messes. Here, watch this," He said,
/grabbing a nearby marker and scribbling on the counter. He then turned the clean inator on, and it shot a jet of bright green light at the markings. When it faded, the drawing on the counter was gone. "Cool!" Phineas exclaimed. "I like to build
stuff

too. I'm Phineas, and this is my step-brother and best friend Ferb, and this is myother best friend Isabella."

"I'm Doctor Heinz Doofenshmirtz," their teacher said. "You seem vaguely familiar," Phineas said. "Have we met before?" "You know, I think I remember you three from somewhere, although I'm not sure from where," Doofenshmirtz said. Slowly, more and
more

students trickled in, all slightly taken aback at the strange appearance of the took his seat between Ferb and Isabella. Since they were in a lab, they were sitting on stools by counters.

"Hello, class," said Doctor Doofenshmirtz as the bell rang. "My name is Doctor Heinz Doofenshmirtz, and I will be your Biology teacher for the year." He wrote Dr. Doofenshmirtz down on the blackboard as he said this. "Did everyone bring their
textbooks?"

Everyone nodded, and a few kids even pulled them out. "Good, because we're almost never going to use them. We will rarely have tests or homework, and most of our learning will be through hands-on experiments." "No tests or homework? Baljeet would
/have flipped!" Isabella whispered to Phineas. "I dunno," Phineas whispered back. "This seems like my kinda class."

"Hey, you kids. Phineas and Isabella, right? You know, I'm fine with group discussion. Seriously. If you know me, you know I'll never shut up. But please, if I'm talking, don't chat. You can flirt after class."

Both Phineas and Isabella turned pink in the face. Isabella felt her heart start beating fast. Of course, once I give up my crush, now people assume I'm flirting.

Phineas had a funny feeling I his stomach. He thought we were flirting. He was probably joking. But were we? No, we weren't. We were having a friendly conversation. Right?

"Anyways," Doctor Doofenshmirtz continued, "If you want to ask a question, just shout it out. Don't bother with the whole, 'raise your hand' thing. I means, seriously, who came up with that? 'I'm going to stick my hand it the air and wait for someone
/to give me permission to ask a question.' So, point is, if you want to ask something, just shout it out."

"Why do you talk so much?" Buford asked. Phineas hadn't noticed him until now. "It's in my nature," Doctor Doofenshmirtz replied. "We'll be learning about human nature in the second semester. But for now, we're going to start with a mini lab. I'm
going

to pass out these DNA samples, and we'll investigate using microscopes and magnifying glasses. There's this whole experiment I could do with a piece of hair and some tweezers, but I did I My first year teaching and it did not end too well." "What
/happened?" Phineas Asked. "Well, I ended up giving my daughter's ex-boyfriend an alligator's tail and a gorilla's arm, but whatever, it's all in the past now."

About half an hour later, while everyone was finishing their lab, the door opened. "Hey, Dad," said a girl who looked about Candace's age. "I brought your coffee." "Thank you, sweetie," Doctor Doofenshmirtz said. "Class, this is my daughter, Vanessa."
/"Hi Vanessa," a few kids said. "Hey, guy," Vanessa replied. "Well, I gotta go. Monty said he'd meet me at the coffee shop in ten minutes. Bye." She kissed Doofenshmirtz on the cheek and left.

"Hey, Ferb, do you have the third sample?" Phineas asked. "Ferb? Ferb?" Ferb was still staring at the door. "Hey! Ferb!" Ferb blinked sharply and turned to Phineas. "Sorry," He said, and handed him the third disk. "Here, Phineas, I've got
the vinegar

and baking soda," Isabella said, handing it to him. "Thanks," Phineas said, and again he felt like his stomach had jumped down to his feet. She handed the supplies to him, then turned to write something down in her notebook. Phineas stood, mesmerized
/by Isabella's hair, which was still swaying a little from when she turned. He never noticed how nice it looked, with subtle blue highlights and tied up in a loose braid. Suddenly he realized he'd been staring at her for a solid minute, and quickly
/turned away, his heart beating much too fast. I hope she didn't notice, he thought to himself. What's wrong with me? Suddenly the realization hit him. Oh my gosh. I like Isabella. Oh no. This can not be happening!

Out of all the girls in the world, he had to develop a sudden crush on his best friend. But now that he thought about it, he'd probably been liking her since the end of eight grade. And what wasn't there to like? She was smart, funny, sweet, nice,
optimistic,

and super cute. But why her? She'll think I'm weird. I've been her best friend her whole life, and if I suddenly tell her I have a crush on her, she'd probably stop hanging out with me.

Brrrrrrrring!

The bell jerked Phineas back into reality, and he packed up his bag and headed on to his next class.
