Elmo devours you

Sans! Sans! Wake up!
What is it, dude?
A human has fallen from the surface world
Really? And you got a bone to pick wit'im?
No time for puns
Come on, that was a real rib-tickler, ayy
Ugh! Enough!
Alright, here we go again

Welcome to the Underground
How was the fall?
If you wanna look around
Give us a call
We don't see humans often
We're happy you just dropped in
I'll be so popular when I show all the monsters what I just brought in

Hey! Papyrus, mind your manners
Can it, Sans, no time for banter
Excuse my brother, he's a bit eccentric
You're just lazy and apathetic
Call me what you want, I got thick skin
Another bad joke and I'm finished with him
We are monsters, the awfullest kind
To mess with us takes a lot of spine
