Perry the Platypus Theme

Perry the Platypus is the theme song played when Agent P is doing his missions to stop Dr. Doofenshmirtz. The song was first sung fully at the end of the first Phineas and Ferb episode, "Rollercoaster", and since then, small parts of the song (mainly "dooby dooby doo ba") have been sung on Perry's missions.

Lyrics
Backing scat: (Dooby dooby doo-bah) X4 Female Singers: Perry!

Male Singer: He's a semi-aquatic, egg-laying mammal of action! Backing scat: (Dooby dooby doo-bah) X2 Male Singer: He's a furry little flatfoot, who'll never flinch from a fray-ee-ay-ee-ay! He's got more than just mad skill, Female Singer: (Wah-ah-ah) Male Singer: He's got a beaver's tail and a bill, Female Singer: (ah-ah) Male Singer: And the women swoon whenever they hear him say:

(pause; Perry chatters and women faint)

Male Singer: He's Perry, Perry the Platypus!

(Extension as heard in One Good Scare Ought to do It!)

Major Monogram: But you can call him Agent P. Male Singer: Perry!>br? Major Monogram: I said you can call him Agent P! All Singers: A-gent-P!
