| "Honk!" — Sweary's sound |
Sweary the Swan[1] is a swan and Perry the Platypus's counterpart in the episode "Steampunx".
Biography[]
Like Perry, he is normally acting like a "mindless swan" in front of Phineas and Ferb, but he has the double life of a secret agent fighting Professor Von Doofenshmirtz. He is frequently accused of using coarse language by everyone who hears him, hence the name, though to the viewer's ear he seems to simply make normal swan noises.
