The Ballad of Badbeard, when Phineas, Ferb, Isabella, Baljeet, Buford, and the Fireside Girls search for Badbeards treasure.
Here's the lyrics:
Older Version -
Clyde Flynn: Arg, arg, arg, arg, this is the Ballad of Badbeard!
Arg, arg, arg, arg, this is the Ballad of Badbeard!
New Version -
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: 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!
Arg, arg, arg, arg, This is the Ballad of Badbeard!
