Richard: (trumpet playing) All hail the King! Bootjet Groovestar! Yay!
Bootjet Groovestar: Thank you! And now I'd like to sing a song about my favorite letter, the letter B.
Dr. Teeth: Oh, B. I love it! Sing it!
Fozzie Bear: Nice voice.
Bugs Bunny: Do your thing!

Bootjet Groovestar: Yeah, the blues begin with the B,
so they're the only kind of songs I sing.

Bootjet Groovestar: Without the letter B...
Jasper Beardley: Without the letter B!
Bootjet Groovestar: There couldn't be a beard.
Dr. Teeth: My beard!
Bootjet Groovestar: Without the letter B,
No, we couldn't have a beard.

Bootjet Groovestar: Without the letter B, there'd be no Fozzie Bear.
Bugs Bunny: Bye, Fozzie Bear. So much for you!
Bootjet Groovestar: And there'd be no Bug Bunny!
Bugs Bunny: That's Bugs!
Bootjet Groovestar: That's why I'm feeling blue.
Dr. Teeth: Bye, Bugs!
Bootjet Groovestar: Without the B, there'd be no Ferocious Beast.
There'd be no Yogi Bear.
Jasper Beardley: Poor Yogi Bear.
Bootjet Groovestar: There'd be no King Bootjet Groovestar.
Jasper Beardley: Wow, he vanished in thin air!
Bootjet Groovestar: But we do have the letter B.
Everyone: Let's hear it for the letter B!
Jasper Beardley: Oh, yeah!
