Summary
Believing that everything in his life could be fixed if he had only become class president in High School, Heinz Doofenshmirtz uses his past invention, the De-Age-inator, to become 18 years old again and quickly enrolls in Danville High. However, in the high school political arena, Doof faces fierce competition from his opponent, a girl named Candace Flynn, whom smells something fishy about the new "exchange student" and soon sets out to bust him!
When the two are paired as soccer rivals and then lab partners, though, their mutual understanding soon works against them and turns their fierce rivalry into something neither of them expected.
Heinz now has to ask himself if he's evil enough to take his daughter's friend to the prom before taking over the Tri-State area, while Candace has to answer, once she gets the evidence she craved, if she's prepared to bust someone she's fallen in love with? And if she'll really be okay this time when everything disappears.
It seems neither teenagehood nor middle agedness is all it's cracked up to be.

Summary
Perry and Heinz aren’t the textbook definition of nemesis. No matter how many times they refer to each other as such— it’s been a while since anyone who knew them would back them up on that.
The true nature of their relationship, however? Well, that depends on who you ask.
Or, whatever Perry and Heinz are, through the eyes of many, many bemused bystanders. -

Summary
Though it had completely slipped Stacy's mind that tonight was the date night Candace had been planning for two weeks. Candace was taking Jeremy out for a fancy dinner and drive in return for all the times he had done the same for her, now that she also had both a license and disposable income.
In her defense the stress of being cornered by killer robots should have been more than a good enough excuse to explain her forgetting such a thing. -

Summary
When a mysterious rift threatens the fabric of time itself, Perry the Platypus is critically injured while protecting both the Tri-State Area and his secret identity. As OWCA scrambles to stabilize him and contain growing dimensional chaos, Phineas and Ferb struggle with their pet’s sudden disappearance. While their summer slows to a standstill, Stacey—now reluctantly pulled into OWCA as a temporary operative—must keep Perry’s secret and support her heartbroken best friend Candace, who begins to unravel under the pressure of watching her brothers lose their spark.
Meanwhile, Doofenshmirtz confronts his past while attempting to help the former-nemesis who has helped him countless times. With the help of the 2nd Dimension Resistance crew, OWCA races to uncover the truth behind the worsening rift crisis and save not only Perry but the entire Tri-State Area.
As timelines fray and bonds are tested, Perry must fight to recover, protect the boys he loves, and remind everyone what truly holds the multiverse together: loyalty, found family, and the quiet strength of a platypus who never gives up.

Summary
Carl just got a zero on a ten-page, perfectly cited essay—because his font didn’t have enough “aura.”
It wasn’t the first time. After months of absurd grading, personal jabs, and being told his tie color clashed with his thesis, Carl is at his breaking point. The university won’t help. His professor has tenure. And Carl? He’s just an unpaid intern with student loans and a dream of finally graduating.
But he’s not alone.
Monty launches a full investigation. Monogram gears up for war. And Perry the Platypus? He’s already built a case file thick enough to take down a supervillain.
This time, the mission isn’t about saving the world—it’s about saving Carl’s future.
Operation: Academic Justice has begun.
