Lyrics
Miss Piggy's Big Number: I am blue. Oh, so blue. Yes, I'm blue because I don't know enough about you. I am blue. Really blue. It is so that I can show how I care about you. One of me all the times you see me on my own. Could it be that you think I'm happy all alone? I am blue. Oh, so blue. And I'll keep on being blue because what else can I do? (sighs) Yes, I'll keep on being blue till I'm closer to you. (sighs)
