Act Your Age

40

Ten years into the future, Phineas and Ferb and the gang have all graduated from high school and are reaching the end of their last summer together before going their separate ways to college. Everyone seems to have decided what they're doing except for Phineas, who is having trouble deciding which school to go to after having been accepted into many different collages and universities around the world. He's also soon hit with another personal bombshell: his friends finally tell him that Isabella has been harboring a crush on him since they were little kids, a fact that had been obvious to everyone but Phineas himself. With love on the line, the gang works to get the two to confess their feelings for one another before Isabella leaves for college. Meanwhile, Perry helps Doofenshmirtz get through his midlife crisis.
