Walt Disney Television International (India) director of programming and production Aparna Bhosle said, "The series reflects Disney Channel themes of 'follow your dreams,' 'believe in yourself' and 'celebrate your family.' A combination of well-told stories of relationships and great action, this series is designed to appeal to both boys and girls across all markets."

As the series unfolds, Phineas and his stepbrother, Ferb, build a backyard beach complete with surf competition, create a new season - one with both sun and snow -- called "swinter," and assemble a theme park-sized roller coaster, all just outside their back door. Throughout the escapades, they're accompanied by Perry the Platypus, their seemingly mindless family pet. But unbeknownst to everyone, including Phineas and Ferb, Perry is also Agent P, a suave secret operative who faces off with the ridiculously evil Dr Doofenshmirtz.

Each episode opens with Phineas and Ferb figuring out what they want to do that day and by the end, three storylines converge: 1) Phineas and Ferb's adventure, 2) Candace's attempt to juggle typical teen concerns while tattling on her brothers and 3) Perry the Platypus battling the evil Dr Doofenshmirtz.
