"What'cha Doin'?" is a song in "Rollercoaster: The Musical!" sung by Isabella and the Fireside Girls. The song is a musicalization of Isabella's catchphrase and the real intentions of what she wants when she says it.

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: 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' head and hearts. This represents Isabella's love and affections for Phineas.
  • This is the second time Isabella sings about Phineas ("City of Love").
  • Adyson and Ginger do not appear in this song, though the other regularly seen Fireside Girls do.
  • This is the third time Isabella sings her catchphrase (The Dad-inator, "We Wish You A Merry Christmas"); second time it is in an episode.
  • This is the fourth time the song starts slow, then gets fast ("Spa Day", "Atlantis", "Wedding Adventure").
  • Isabella's line "By any chance, could it include me?" is a reference to when she asks if she can join the boys in their big ideas.
  • This song has background vocals by Danny Jacob.

Errors[]

  • When Katie and Milly first appear, they disappear for a split second then appear again.
  • Speaking strictly, 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"). However, this lyric was probably meant to be taken as a figure of speech.
