Lyrics:

Back Sactters: Doo-Be Doo Be Do-Ba Doo-Be Doo Be Do-Ba Doo-Be Doo Be Do-Ba Doo-Be Doo Be Do-Ba

Female Singer:Perry!

Male Singers:He's a semi-aquatic egg-laying mammal of action,

Back Scatters: Doo-Be Doo Be Do-Ba Doo-Be Doo Be Do-Ba Doo-Be Doo Be Do-Ba Doo-Be Doo Be Do-Ba

He's a furry little flatfoot who'll never flinch from a fray,

He's got more than just man skill,

He's got a beaver tail and bill,

And the women swoon whenever they hear him say:

Perry:*platypus sound*

*ladies faint*

Male Singer:He's Perry,

Perry the Platypus!

Major Monogram: But you can call him Agent P.

Male Singer: Perry!

Major Monogram: I said you can call him Agent P!

Male Singer: Agent P!
