Lyrics
Who's been messing up everything?

It's been Agatha all along

Who's been pulling every evil string?

It's been Agatha all along

She's insidious (Ha-Ha!)

So perfidious

That you haven't even noticed

And the pity is

(The pity is)

Pity, pity, pity, pity

It's too late to fix anything

Now that everything has gone wrong

Thanks to Agatha (Ha!)

Naughty Agatha

It's been Agatha all along! [And I killed Sparky too!]
