"Little Girl Blue" is a song in the Darkwing Duck pilot, "Darkly Dawns the Duck". It is a lullaby performed by Darkwing and Gosalyn, during which the former discovers that the lyrics are revealed to be the arming code to the Ramrod. As it turns out, Darkwing's meeting with Gosalyn wasn't a coincidence, but a destiny.
Lyrics
Gosalyn: (sung)
Close your eyes, little girl blue,
Inside of you lies a rainbow.
Yellow, blue, red blue,
purple too,
Blue, purple and green,
then the yellow.
Darkwing: (spoken)
Not much on lyrics. Let me try.
Darkwing: (sung)
Rest your head, little girl blue,
Come paint your dreams on your pillow.
I'll be near to chase away fear,
So sleep now and dream 'til tomorrow,
I'll be near to chase away fear,
So sleep now and dream 'til tomorrow.
Darkwing: (whispered)
Good night, Gosalyn.
