Perry the Platypus (song)

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

Lyrics
Note: The song was extended in the DVD extra episode "One Good Scare Oughta Do It!" to show the full song. That is:

(Singers) PERRY!

He's a semi-aquatic, egg layin' mammal of action

Dooby, dooba, Dooby, dooby, dooba,

He's a furry little flat foot, who'll never flinch from a fray-e-ay-e-ay!!!

He's got more then just mad skill

He's got a beaver tail and a bill

And the women swoon, whenever they hear him say:

(Perry chitters his noise)(Fainting sighs from women)

He's Perry; Perry the Platypus!!

(Monogram) But you can call him Agent P.

(Singers) Perry-

(Monogram) I said you can call him Agent P.

(Singers) A-GENT P!!!

Trivia

 * The song was altered in the episode "Does this Bill make me look Fat?", where Candace switches bodies with Perry. When he/she went on his/her mission, this was the song that played at the end of the episode, during the end credits.
