Hey guys, Now before this sparks any controversy, I know the idea for this story sounds similar to ideas made by big authors such as Axis23 (The Chromosome Shopper), Foobar13 (Phineas the Fireside Girl) and a requested drabble made by irresistiblecookie for their drabble series (Two Words, Please), those stories/chapters were actually my inspiration for this One-Shot.

Things might be a little O.O.C in this fanfic, but then again, they are 6/7 years older

Disclaimer: I don't own Phineas and Ferb

(Phineas' P.O.V)

It was a pretty average day for Ferb and I, now 16 and 17, Ferb had started to talk a lot more, Isabella had stopped coming over so early and I was a lot taller. We had made a one use Gender-change Ray (TOUGR)- by the way, we don't usually make stuff that has only one use before it disappears (well, not intentionally, anyway) - we knew it was very faulty, to be fair I don't quite know why we didn't just throw it straight into the vault.

Anyway, Ferb had gone back inside to get some drinks. So I went to sit under the tree and see if I could find out why it was so faulty, when all of a sudden, while I was messing with it. It fired its beam right at my face and then disappeared. I felt myself becoming a few inches shorter than I once was, all the while I was too shocked at my shrinking size to realise my chest was heavier than usual, and that my hair was now touching the grass I was sat on. I felt curves slowly form around my abdomen and I felt my privates dissipate and form... woman... private parts.

'Well at least we now know it would've worked' I thought to myself, Isabella had stopped coming over so early

(Ferbs P.O.V)

As I walked out I dropped the two glasses of lemonade I had in my hands and just froze there, mouth agape as I saw, first hand, a now female Phineas

"Hey Ferb" He shouted at me in a relatively high-pitched voice, he then went on to explain what had happened

"You can build another one to change me back though, right Ferb?"

"Yes." is all I could sputter out. it wasn't until ten minutes later I collected my marbles and asked:

"Umm.. what should I call you now, y'know. Seeing as your a girl 'n' all"

"How about Phoebe?" was all Phineas... uhh... Phoebe could get out.

"Yeah, that sounds good" I simply replied

thinking About how the hell I was going to tell Phoebe about the fact we cant build a new TOUGR, I saw Isabella coming across the road. "Oh dear god" I thought to myself

(Phoebe's P.O.V)

'Hide' I saw Ferb gesture to me, thinking on my feet, which were now smaller than they used to be, I quickly stumbled over and fell out the front door and ran to the mall, desperately holding my trousers up.

(Ferbs P.O.V)

"Hey Isabella" I said in the calmest voice I could

"Hey Ferb, Is Phineas here?" Isabella replied

"Um, no." I said, tugging on my collar. "He's inside"

Isabella sighed. "Oh okay then. Just tell him I'm going to the mall today."

"Okay, see ya" I ended with as I saw Isabella walking towards the Googolplex Mall.

(Isabella's P.O.V- 10 Minutes Later)

As I was browsing my favorite store for more dresses, I thought I saw Phineas looking next to me 'This is stupid, she's a girl, come on Isabella' I thought, however the mysterious girl took one look at me and moved away pretty quickly.

"Man, whats her problem?"

(Phoebe's P.O.V)

As I looked at the dresses in the aisle opposite Isabella, I debated confronting her, after about 10 minutes of looking I decided I probably should, she'll find out soon anyway.

(No-ones P.O.V)

=2 seconds later=

"Wait wait wait, so you ARE phineas?" Isabella exclaimed, surprised. She'd been bisexual for a couple of years now, but had never told anyone.

"Yeah, me and Ferb built a one use gender-change ray for Donovan, you know, the feminine kid, and it kinda fired while i was trying to fix the faults with it and hit me, and there is no way for me to go back, at all. And it's really annoying because I was going to confess my love to you lat-". Crap.. did I really just say that? Phoebe waited for Isabella to say something, all the while trying not to run away and lock herself in a changing room.

"Well, I have been bisexual for a couple of years now... Do you still want to be together?"

"Yeah, I do, more than anything..." Phoebe said, clearly upset.

"Should we try?" Isabella asked

Phoebe's answer came almost instantly. "Yeah".

Then they kissed.

(Ferb's P.O.V)

"How are we going to explain this to Mom and Dad?" I questioned myself

I'm Phinabellalives and i'm bad at sign-offs, see ya
