What'cha Doin'?

What'cha 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

What'cha doin', what'cha doin'?

What's the day's activity?

What'cha doin', what'cha doin'?

By any chance, could it include me?

What'cha doin'? What'cha doin'?

Fireside Girls: (What'cha doin'?)

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

Isabella: What'cha doin', what'cha doin'?

Fireside Girls: (What'cha 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: Oh, don't you know, Phineas, you have no idea

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

And say...

Isabella: What'cha doin', what'cha doin'?

Fireside Girls: (What'cha doin'?)

Isabella and Fireside Girls: I really wanna know

Isabella: What'cha doin', what'cha doin'?

Fireside Girls: (What'cha doin'?)

Isabella: Can I be part of the show?

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

What'cha 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.

Errors

 * When Katie and Milly first appear, they disappear for a split second then appear again.
 * The line "Every day I come over" is incorrect, as Isabella does not show up for some of Phineas and Ferb's projects ("I, Brobot" to name one) or is just surprised to see them when they visit her (such as "Ready For The Bettys").

Continuity

 * Once again, Isabella sings mostly by herself. ("City of Love" and "The Yellow Sidewalk")
 * Third time Isabella sings her catchphrase. ("The Dad-inator", "We Wish You A Merry Christmas") This is the first time though 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 "I Scream, You Scream", "One Good Scare Ought to Do It!" and "Hail Doofania!". Or, it could be a reference to when she asks if she can join them as in "The Fast and the Phineas" and "De Plane! De Plane!".
 * This is the second time Isabella has sung about Phineas. First was City of Love.

Songwriters

 * Michael Culross
 * Jeff "Swampy" Marsh
