I'll take you to the castle

It would be no hassle

Know what I mean?

Well, there's a little issue

See, I made an artificial killing machine

There's no need to worry, though

You have me right here, so

You'll survive his rage

Though I'll lead from the rear

I'll still be here

Even when Mettaton steals the stage

(Song: Alphys - UTM)

Welcome, human, to the Hotland's Core!

The source of all our power

Named by our great hunky king Asgore

Fueling us every hour!

We're all living here among the heat

Amongst our blood and sweat, and

Waiting for the day we'll see the sky

Though it hasn't come yet!

(Song: CORE - UTM)
