A Dark Crystal PREQUEL would be possible, but a sequel would never work. It's the same with this, except a prequel wouldn't even work.
"When I was younger,
Just a bad little kid,
My momma notised funny things I did.
Like shootin' puppies with a b-b gun.
I'd poison guppies, and when I was done,
I'd find a pussycat and bash in it's head!
That's when my momma said...
What did she say?
She said: "My boy, I think someday
You'll find a way
To make your natural tendencies pay!
You'll be a dentist!"
How they didn't win an Academy Award for that music, I will never know.
The one guy died while scoring Beauty and the Beast, right?
