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'?
(Whatcha doin'?)
Isabella and I don't mean to disturb
Whatcha doin', whatcha doin'?
(Whatcha doin'?)
Isabella and You know it's not really directed at Ferb
When I say-ay-ay-ay-ay
Whatcha doin'?
Oh, don't you know, Phineas, you have no idea
That every day I'm just dyin' to see ya?
And say
Whatcha doin', whatcha doin'?
(Whatcha doin'?)
Isabella and I really wanna know
Whatcha doin', whatcha doin'?
(Whatcha doin'?)
Can I be part of the show?
Isabella and When I say-ay-ay-ay-ay
Whatcha doin'?
