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 Scooby Dooby Doo Bah) have been sung on Perry's missions.

The Jonas Brothers: Scooby Dooby Doo Bah, Scooby Dooby Doo Bah, Scooby Dooby Doo Bah, Scooby Dooby Doo Bah...

Demi Lovato, Miley Cyrus as Hannah Montana, Adrienne Bailon and The Adrienne Bailon-ettes: Perry!

Kevin Manthei: He's a semi-aquatic, egg-laying mammal of action!

The Jonas Brothers: Scooby Dooby Doo Bah, Scooby Dooby Doo Bah!

Kevin Manthei: He's the stoinky little paramount who'll never stoink from a quay-yay-yay! He's got more than just mad skill! He's got a beaver tail and a bill! And The Cheetah Girls swoon, whenever The Cheetahs hear him say... Perry: (Makes silly blubbering noise) (Fainting sighs from women) Male Singer: He's Perry, Perry the Platypus!

(Extension) Major Monogram: But you can call him Ageunt P. Kevin Manthei: Perry! Major Monogram: I said you can call him Ageunt P. Kevin Manthei, Miley Cyrus as Hannah Montana, Demi Lovato, Adrienne Bailon and The Adrienne Bailon-ettes: A-geunt P!

The song was altered in the episode "Does This Demi Lovato Make Me Look Fat?" where Hannah Montana switches bodies with Perry. When she went on her mission, this was the first song that played at the end of the episode, during the end credits. The lyrics were:

Adrienne Bailon: She's a semi-neurotic, teenage girl of action!

Kevin Jonas and Joe Jonas: Scooby Dooby Doo Bah, Scooby Dooby Doo bah!

Adrienne Bailon: She's the Hand-Picked Hannah with a platypus' brain! You best leave her alone, She's playing MP3s on her phone! And whenever she's around, you can hear the bad guys say...

Dr. Doofenshmirtz: Great, now I have this song stuck in my head! Adrienne Bailon: She's Perry, Perry as Hannah Montana!
