Fireside Girls Anthem

This was the song sung during "Isabella and the Temple of Sap". It appears to be both their anthem and the encouragement-song.

Lyrics
All: We're Fireside Girls, one and all

And together we belong.

We wear our patches upon our sashes,

And stand cute, small, and strong.

This is the Fireside Girls song...

And it's not too terribly long!

Trivia

 * During the line "we wear our patches upon our sashes", Isabella is shown with an "I Just Saw A Cute Boy" patch, most likely referring to Phineas.

Continuity
The melody of this song is heard several times when Fireside Girl-specific events are introduced, such as revealing their club house.
