Lyrics for this song:
Phineas: Avast, me 'arties!

We're sailing for the Isle of Spleen,
To search for the Treasure of Badbeard!

Holly: I'm feeling sick.
Gretchen: You're looking green.
All: We search for the Treasure of Badbeard!

Buford: We'll plunder and pillage
Baljeet: And do some math
Ferb: And all refuse to take a bath

Isabella: We seek adventure and romance
Baljeet: I'm running out of underpants!

All but Ferb: There's ghosts who haunt the cave, and worse:
Talking Skull: It's guarded by a pirate's curse!

Candace: Why do my nostrils whisper to me?

All: Arg, arg, arg, arg, This is the Ballad of Badbeard! (X2)
