... I am so sorry (#ABSOLUTELYnotsorry) that I made this at three in the morning, showed it off to everyone at school (who knew the show, of course), and now posting it on my accounts. <"/, c"|, all other characters belong to: Dan Povenmire, Swampy Marsh, and Disney; I suppose. I only own the randomness that will never happen in the show. I swear this was all tumblr's fault...

A Phineas and Ferb fanfic. What happens when the effects of one of Doof's Inators lasts a little too long on Perry? What will the boys think? Will they find out Perry's secret? Or will they forever be his boys?

All of Dr. Heinz Doofenshmirtz's Lines. Everything he says, ever. I do not own Phineas and Ferb. The rights belong to the creators, Dan Povenmire and Swampy Marsh. I am also going by the episode list on Disney+. I am also using the subtitles a lot when I don't really know what he said, so it may be sometimes wrong. Doof is, sadly, just a very relatable kind of guy.

DISCLAIMER: I wrote this for my physics class as a five page paper with my friends for fun. ~ It's the year 2015. Located in a small suburb of the Tri-State area, live Phineas and Isabella Flynn. Join Phineas in his mission to locate a pair of lost car keys in a desperate attempt to please his wife. His efforts soon turn rogue in a time traveling adventure gone wrong, led by Dr. Heinz Doofenshmirtz. Will Phineas find the missing set of car keys in the future or will something happen to him first? Will he be able to return to his proper time period or will he be lost in a ripple of time? Phineas finds the future is in a dangerously different state. But of course, one would have to continue reading to find out the mystery.

We raced along the bumpy road at the speed of a bullet, shaking wildly. Although I was a bit of a child prodigy, now I was just trembling with fear, not knowing what to do. Suddenly, the car stopped. They opened the trunk. What's next? Will they kill me right here? Or will it be much worse?...

17 year-old Perry Fletcher struggles with balance between his family and his secret agent job that they still don't know about during a hectic summer, but little does he know that this summer is just getting started.

The gang noticed something's wrong with Isabella. They recreate the device they used to go into Candace's subconscious. What will happen? As you can tell by the title this is a phinbella story (OTP) I hope you guys enjoy my story!!!

When sixteen year old Vanessa Doofenshmirtz takes a job babysitting her friend Candace's younger brothers Phineas and Ferb, she has no idea of the adventure that she's getting into. Especially when her father, Doctor Heinz Doofenshmirtz, invents a device called the De-Age-Inator, which is supposed to turn his brother Roger into a child, thereby making him unable to be Danville's mayor and allowing him to take over. When the Inator hits Vanessa after Doofenshmirtz accidentally fires it while explaining his evil scheme to his nemesis, Perry the Platypus, she finds her feelings for Ferb beginning to change. While all of this is occurring, Doofenshmirtz begins working on an Inator to reverse the effects of the De-Age-Inator. I don't own Phineas and Ferb, and all rights belong to Disney and the creators of the show and characters, Dan Povenmire and Jeff "Swampy" Marsh.

Major Monogram and Heinz Doofenshmirtz host a reader's choice top 14 musical countdown from season 1 of Hira's Adventures with a genius girl named Hina, while Doofenshmirtz disguises his Musical-Video-Mind-Control-Inator as a Musical-Videoclip-Inator, though Hina is doing some tinkering on it for some reason. Note: Season 2, Episode 4, During Hira and Hiro Stays With Phineas and Ferb Storyline.
