Phineas And Ferb: Season 3, Episode 3

3 - 3:

Run, Candace, Run-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, who turns out to be a long lost relative of the Johnson family, that it is not worth buying. Last Train to Bustville-Phineas and Ferb and their friends have a hot air balloon race to the top of Gerhardt Summit while visiting their grandparents, while Candace gives up on trying to bust Phineas and Ferb.
