It is comon knowledge that girls mature four years before boys, for Isabella this couldn't be more true.

Forgetting an entire person is not something you can get over just like that. Especially when said person is very close to you... (Takes place the night after Last Day Of Summer.)

Isabella kisses Phineas with the knowledge that everyone, herself included, will forget the day's events. Only that's not what ends up happening. At all. (a generic alternate ending of "Across the 2nd Dimension"; Phinabella)

A story based on The Last Day of Summer: an alternate turn of events that occurs after Doofenshmirtz destroys the Do-Over-Inator and moves out of the Tri-State Area in his efforts to give up evil; leaving Candace as the only person in the whole city who remembers the two brothers that she used to have.

Phineas and Isabella have been friends for nearly their whole lives and no body has had much if any luck fixing that but will a new perspective be just what they need? Lame summery, I know.

When Phineas and Ferb start their first year of junior high, Phineas meets a girl that will turn his entire wold upside down. Relationships are formed, friendships are questioned, hearts are broken, and secrets are realized. This is the extended version of my story "The New Girl" with more in it and some slight changes. If you have read the original then don't spoil the ending.

sometimes it's better to keep something a secret, sometimes it's better to tell someone that there best friend has a crush on them, but it's always better to stop someone from announcing that Isabella has a crush on someone over the loud speaker, especially since more than 80% the boys at school have a crush on her … Yet for some reason none of them know who she has a crush on.

To Marie, fate was cruel. It hated her family. It burdened her father. It seemed unchangeable. With her father's new device, Marie is determined to bring back the one person who's fate resulted in her existence. I do NOT own P&F, its characters or locations, or the OCs Marie and Thomas.

Lame title is lame... anyhoot 'n holler, I wasn't even gonna write this story, but drawing the cover art made me. XD hope ya'll like it ! T for violence. Phinabella fluff because I'm me. XD

Marie Flynn and Thomas Fletcher are kidnapped by two mysterious strangers who challenge Phineas and Ferb to find them. Now, the two fathers must struggle against this elaborate plot of revenge and find few good options. Can they rescue their children before the worst happens? MARIE FLYNN AND THOMAS FLETCHER DO NOT BELONG TO ME!

After a young life of being happy and carefree, Marie Flynn begins to learn a dark secret that her parents have been keeping from her. What happened to her and how did it effect her?

Phineas has always been Ferb's one and only best friend. That is of course BEFORE he met Phineas. What if Ferb reunites with the girl that he's been thinking about ever since they were seperated? Will it make or break Phineas and Ferb's March Break?

-Sequal to The Big Bang Marie-. Ferb meets up with his future niece, Marie Flynn, once again so she can see her parents from their own childhood, but soon fine that her own existence is in danger, and she'll need Ferb's help to save her.
