“Phineas and Ferb’s” next season will feature new guest appearances from notable actors, musicians, athletes and more. They will join Vincent Martella and David Errigo Jr. as stepbrothers Phineas Flynn and Ferb Fletcher, respectively, Ashley Tisdale as Candace Flynn, Caroline Rhea as Linda Flynn-Fletcher, Dee Bradley Baker as Perry the Platypus, Alyson Stoner as Isabella Garcia-Shapiro, and co-creators and executive producers Dan Povenmire as Dr. Heinz Doofenshmirtz and Jeff “Swampy” Marsh as Major Francis Monogram.
The new season of “Phineas and Ferb” will follow the inventive stepbrothers as they tackle another 104 days of summer. Candace is more determined than ever to finally bust her little brothers while their pet platypus, Perry, continues to lead a double life as the suave Agent P whose sole mission is to thwart Dr. Doofenshmirtz from taking over the Tristate area.
