"What's This?" is a song from the film, The Nightmare Before Christmas sung by Jack as he is exploring Christmas Town as he discovers something the citizens of Christmas Town do differently than the citizens of Halloween Town do differently. A reprisal of the song was sung when Santa made it snow in Halloween Town.
Jack: What's this? What's this?
There's color everywhere
There's white things in the air
I can't believe my eyes
I must be dreaming. Wake up, Jack! This isn't fair! What's this?
What's this? What's this?
There's something very wrong
There's people singing songs
The streets are lined with little creatures laughing
Everybody seems so happy. Have I possibly gone daffy? What is this?
There's children throwing snowballs instead of throwing heads
They're busy building toys. And absolutely, no one's dead!
There's frost on every window. Oh, I can't believe my eyes
And in my bones, I feel the warmth that's coming from inside...
They're hanging mistletoe
They kiss... Why, that looks so unique.
Inspired, they're gathering around to hear a story, roasting chestnuts on a fire. What's this?
What's this in here?
They've got a little tree
How queer! And who would ever think?
They're covering it with tiny little things
They've got electric lights on strings. And there's a smile on everyone. So, now, correct me if I'm wrong!
This looks like fun this looks like fun.
Oh, could it be I got my wish?
Oh my, what now?
The children are asleep
But look, there's nothing underneath
No ghouls, no witches here to scream and scare them
Or ensnare them, only little cozy things secure inside their dreamland...
The monsters are all missing and the nightmares can't be found
And in their place, there seems to be good feeling all around
Instead of screams, I swear
I can hear music in the air
The smell of cakes and pies are absolutely everywhere...
The sights, the sounds
They're eveywhere and all around
I've never felt so good before
This empty place inside of me is filling up
I simply cannot get enough
Oh, I want it. Oh, I want it
Oh, I want it for my own
I've got to know, I've got to know.
What is this place that I have found?
What is this?
(speaking) Christmas Town? Hmm...
Santa Claus: Ho Ho Ho Ho... Ho Ho Ho Ho!
- This song can also be heard in a 1997 trailer for Disney's Flubber and other movie studio trailers. It is also heard in the theatrical trailer for James and the Giant Peach.
