Mysterious Force

"Some Mysterious Force" is an unused Phineas and Ferb song written by Martin Olson, that he explains was "cut from the Phineas and Ferb movie" (most likely referring to Phineas and Ferb: Across the Second Dimension). Based on the song's lyrics, it would have been sung from Candace's point of view.

Lyrics
Let me explain, though it might seem strange to you

So please refrain thinkin' bad of me

It gives me pain when I see what my brothers do

But no one else ever can see

I just want the truth known, so I call mom on the phone

But by the time she gets here, the whole thing disappears

Whatever they build every day, it gets taken away

No one sees it, of course, it's some mysterious force

To my mother every story's preposterous

Never believes no matter what I do

But though I'm right and she's wrong, I must confess

I'd prob'ly think I'm crazy, too

I just want the truth known, so I call mom on the phone

But by the time she gets here, the whole thing disappears

Whatever they build every day, it gets taken away

By some mysterious force, no one sees it, of course

Some mysterious force

Some mysterious force

Some mysterious force

Some mysterious force
