Phineas and Ferb (season 3)

Phineas and Ferb's newest invention is a pair of boots which makes the wearer extraordinarily fast. Candace decides to wear them so that she can be in two places at once; at Jeremy's family picnic, where she runs into Mrs. Johnson, and also at the library where she promised Mom she would read to the kids, but things go haywire when she accidentally uses unstable prototypes of the super-speed boots. Meanwhile, Dr. Doofenshmirtz's building is put up for sale so he tries to convince a prospective buyer, Annabelle (voiced by Tina Fey), who turns out to be a long lost relative of the Johnson family, that it is not worth buying.

Candace has no choice but to go to her brothers for help after she loses her phone for the fifth time.

After losing a gift that Jeremy made for her, Candace is determined to recreate it before Jeremy realizes it's missing. Unfortunately, Candace can't remember what it looks like, so she enlists Phineas and Ferb to use their mind machine to enter into her subconscious and recapture the memory. Meanwhile, Doofenshmirtz's evil plan is to use his Underwear-Inator to take over the Tri-State Area, since everyone's greatest fear is being caught in public in their underwear.

After Baljeet announces that he is no longer Buford's nerd, Buford accepts Dr. Doofenshmirtz's proposal to help win over the Tri-State Area. The new partnership causes a problem for Perry since he can't reveal himself as Agent P to Doofenshmirtz without Buford seeing him.

With Fall around the corner, Phineas and Ferb decide to invent "S'Fall", a colorful world full of giant leaf piles and gourds. Meanwhile, over at Evil Inc., Dr. Doofenshmirtz is mentoring Rodrigo, a budding student of evil.
