Watch Phineas and Ferb Online
Summer is all about adventure for stepbrothers Phineas and Ferb in this animated Disney Channel comedy series. They're all about having fun, taking it from building roller coasters all the way to building tree houses, which eventually will morph into a giant robot. While their older sister,… More Candace, tries to catch them, things don't always seem to go her way when their mom comes home and Phineas and Ferb are just sitting under a tree with no evidence to support her, thanks to their pet platypus, who is secretly an agent out to stop an evil, if not slightly childish, genius.
Mom says that Phineas and Ferb have to clean the house and she asks Candace to help, but she refused and instead read the book Mom gave her: The Wizard of Oz. Phineas and Ferb have to spin the house and spray it with a hose, but they spin the house too fast and accidentally knock Candace out, sending her into a Wizard of Oz-esque dream world. At first she finds Perry lying on her and finds out her house has landed in the other world. She journeys to "Bustopolis" to bust her brothers, but soon discovers that evil forces are attempting to get the boots that have grown on her feet.
Phineas and Ferb take on a heroic alter-ego as "The Beak" when unexpectedly becoming superheroes with an indestructible suit they built for an extreme skate track. But, when the villain Khaka Peü Peü discovers them, he tries to terrorize the city, and only The Beak can stop him. Meanwhile, Dr. Doofenshmirtz is temporarily given the mayoral post by his brother Roger to prevent him from being blamed for Khaka Peü Peü's presence.

Irving’s brother Albert doesn’t believe that Phineas and Ferb are anything special, and since he claims to be the “Truth Detector,” he can prove it.
