<P> Phineas and Ferb is an American animated musical comedy television series . Originally broadcast as a one - episode preview on August 17 , 2007 and again previewed on September 28 , 2007 , the series officially premiered on February 1 , 2008 on Disney Channel , and follows Phineas Flynn and his British stepbrother Ferb Fletcher on summer vacation . Every day , the boys embark on some grand new project , which annoys their controlling sister , Candace , who frequently tries to reveal their shenanigans to her and Phineas ' mother , Linda Flynn - Fletcher , and less frequently to Ferb 's father , Lawrence Fletcher . The series follows a standard plot system ; running gags occur every episode , and the b - plot almost always features Phineas and Ferb 's pet platypus Perry the Platypus working as a spy ( `` Agent P '' ) for OWCA ( the Organization Without a Cool Acronym ) , to defeat the latest scheme of Dr. Heinz Doofenshmirtz , a mad scientist driven largely by a need to assert his evilness . Sometimes , other villains scoff at his level of evil . The two plots intersect at the end to erase all traces of the boys ' project just before Candace can show it to their mother . This usually leaves Candace very frustrated . </P>
