What'cha Doin'?

Whatcha Doin' is a song that is in Rollercoaster: The Musical! sung by Isabella and the Fireside Girls.

Lyrics
Isabella: I'm just the curious girl 'cross the way

Every day I come over and here's what I say...

Whatcha doin', whatcha doin'

What's the day's activity

Whatcha doin', whatcha doin'

By any chance, could it include me?

Whatcha doin', whatcha doin'

Fireside Girls: (Whatcha doin')

Isabella and Fireside Girls: I don't mean to disturb

Isabella: Whatcha doin', whatcha doin'

Fireside Girls: (Whatcha doin')

Isabella and Fireside Girls: You know it's not really directed at Ferb

When I say-ay-ay-ay-ay

What'cha doin'?

Isabella: Don't you know, Phineas? You have no idea

That every day I'm just dyin' to see ya...

And say...

Isabella: Whatcha doin', whatcha doin'

Fireside Girls: (Whatcha doin')

Isabella and Fireside Girls: I really wanna know

Isabella: Whatcha doin', whatcha doin'

Fireside Girls: (Whatcha doin')

Isabella: Can I be part of the show

Isabella and Fireside Girls: When I say-ay-ay-ay-ay

Whatcha doin'?

Background Information

 * Much of the background in the song features Phineas's head and hearts. This most likely represents Isabella's love and affections for Phineas.
 * Adyson and Ginger do not appear in this song, though the other regularly seen Fireside Girls do.

Continuity

 * Once again, Isabella sings mostly by herself. ("City of Love" and "Yellow Sidewalk")
 * Third time Isabella sings her catchphrase. ("The Dad-inator", "We Wish You A Merry Christmas") This is the first time though, that it was in an episode.
 * Fourth time the song starts slow, then gets fast. The others songs in broadcast order: Spa Day, Atlantis, and Wedding Adventure. Interestingly, Isabella was singing in all four of the songs.
 * Isabella's line, "By any chance, could it include me?" could be a reference to episodes where Phineas and Ferb's Big Ideas are centered around Isabella like Robot Rodeo and Hail Doofania!
 * This is the second time Isabella has sung about Phineas. First was City of Love
