After a brief mention of their biological father, Phineas and Candace grow curious and decide to do some research, while Ferb wants nothing to do with it. Little do the Flynn-Fletcher siblings know what they're getting themselves into.

Phineas got to read Isabella's letter when the Un-Retrograde Inator hit Ferb instead. However, he was not prepared for what would result both mentally and literally. Meanwhile, Dr. Heinz Doofenshmirtz has enacted a plan that even he didn't plan for thouroughly, and now he has to deal with the aftermath of his own actions.

A whole week dedicated to Perryshmirtz! Heck yeah! But since hates oneshot writers, this fic is gonna be for all my Perryshmirtz week stuff. (Human!Perry, Perryshmirtz, TW's fic-by-fic)

A bunch of stories about the sexcapades of Phineas Flynn and Isabella Garcia-Shapiro. Can be read as one long story or a series of one-shots.

It's the next summer, and Perry is still upset about Phineas and Ferb having their memories of the 2nd Dimension adventure. He secretly gives them their memories back with the Remember-inator. Soon, L.O.V.E.M.U.F.F.I.N begins kidnapping the agents of OWCA for unknown reasons and it's not long before only 7 agents are left; the ones that have a host family.

Season 2 episode 4. While Doofenshmirtz was trying to hit Perry with the Turn-Everything-EVIL-inator one hit the Gelatin pool, but a secound shoot hits Isabella. What will happend to the tri-state ares, or the world.

What happened to Ferb's mom and Phineas and Candace's dad? How did Linda and Lawrence get together? I'm sure there are tons of fanfictions on this topic, but here is mine. I fit in scenes like their first kiss at Love Handel and the meeting in the living room during Stacey's song "Little Brothers." Let me know if you can think of anything important I left out.

The Garcia-Shapiro family received a letter from an old college friend who invited them and their friends on a trip to Vietnam for a change of scenery. They have to wonder, what does this country have to offer to? And will love blossom within their daughter's friends? This story may contain Canon x OC and Canon x Canon Romances.

Taking place after the events of Phineas and Ferb: Across the 2nd Dimension, this story shows Phineas Flynn trying to figure out why he remembers a single clip from a time that he doesn't remember having. After curiosity hits him, he finds himself back in the 2nd Dimension, along with his best friend, Isabella. I do not in any way, shape, or form, own Phineas and Ferb! just this s

When the gang enters their junior year of high school, Ferb is set on finding a girlfriend. He has been teased all through HS because he had a huge crush on a much older girl, Vanessa, who was dating someone else, and he wanted to prove that he could find someone. Little does he know, the girl he meets will change his life forever.

Phineas definitely doesn't want to lose his memories, but he knows he temporarily has to, to keep Perry in the family. So he uploads the video he accidentally filmed to a DVD player for his future self to find.

(Major Character Deaths) Riddled with survivor's guilt after a tragic accident at the local fair, Ferb, Isabella, and Buford attempt to continue on with their lives. But just how do you move forward when you're being haunted by your past? What do you do when they're determined to make you join them six feet underneath?

Sometimes in life, you do something for so long, that's how you define yourself. By that idea. That concept. And sometimes, it's holding you back. (Ferb and Isabella friendship, possibly more?) ENDED, 17 chapters, each chapter about a thousand words after chapter five.

While all their friends are blacked out after a Halloween party, Phineas and Isabella decide to fool around for the first time in months. (Teen Phineas x Isabella one-shot)

All is calm until he receives a call from Linda at 2 in morning.

The words flitted through your brain, a fog dancing between the cracks of your confidence. It was one of those days. (Or, Doof has bad days sometimes, Perry helps him through it, and cuddling never hurt anyone.) Written in second person just because... Also rated T for mentions of child abuse because I'm not entirely sure it's possible for me to write Doof without mentioning it...

It was at the age of seventeen that Ferb Fletcher truly understood the fragility of life. Florescent lights flashed above him and a cool breeze cut through his thin hospital gown as two nurses in masks rolled him toward surgery, and he realized how fleeting every moment in life was, and thus how precious. He also remembered for the thousandth time how much cancer sucked.

Agents don't cry. At least, that's what you tell yourself. [Human!Perry, no TW's]

AU. ¿Que pasa cuando un tesoro oculto durante siglos despierta una intensa búsqueda a través de varios indicios y acertijos? Pues eso es lo que Phineas y Ferb van a hacer, viviendo una intensa aventura llena de intriga, decodificación a la antigua y búsquedas de riquezas antiguas en un tiempo actual.

During one of Perry's face offs with Doofenshmirtz, Ferb shows up. Perry has to avoid him while also thwarting Doofenshmirtz. But Vanessa is there too, and Ferb has a look in his eye. Perry might have other things to worry about besides fighting Doof. Like maybe stopping his best friend from falling for his nemesis' daughter.

Perry gets an unexpected call in the middle of a mission. (Human!Perry)

Mavis Monogram is OWCA's top human agent, so it's only natural that she's paired with OWCA's top animal agent. One summer, she and Perry are sent out every day to the home of one Heinz Doofenshmirtz, who comes up with very pathetic evil schemes and seems to be incapable of stopping. An OC rewrite of PnF Season 1. (if anything is different from canon, assume it's on purpose)

The start of a new series called "If My OCs Were In..." In this story, Nicholas, Anette, and Isabella try to help save Danville by finding out the source of the Pharmacist contagion and get back to Fireside Girls HQ.

Doofenshmirtz's latest inator accidentally turns the citizens of Danville into contagious repulsive pharmacists who run rampant over town. Agent P and the kids must work together to save Danville and avoid becoming mindless zombies themselves. NOTLP but with some changes and an alternative ending!

Here's some oneshots I make over my lunch break! Mostly Phinabella and Ferma.
