Bluebelle is a song sung by Princess Bluebelle and the Powerpuff Girls in the episode Once Upon a Townsville. In this song, Bluebelle introduces herself to the Girls, and the Girls are confused about why they're singing.
Bluebelle: You may have heard that I'm the Princess Bluebelle,
Bluebelle: The daughter of the king and queen,
(Blossom: There's no monarchy in Townsville.)
Bluebelle: Friend of the birds and trees,
I can twirl around with ease,
And I haven't cut my hair since I was three!
(Buttercup: Ew, gross.)
Blossom: Hey, guys, we really should get going home now...
Buttercup: Why are we singing?
Bubbles: I don't know...
Bluebelle: It's 'cause you're all with me,
And because I love to sing,
And it tells the creatures, "Help me do my hair!"
(Buttercup: Dude, enough!)
