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!
