Turn around kid
It'd be a crime
If I had to go back on the promise that sans made for you
So don't step over that line
Or I'll treat you like you treated Undyne

See, kids like you can be so [bad word] 
So I'm here to show you the [bad word] meaning of cool
 [bad word] on, let the room get chiller
Let's go, dirty brother killer

Go ahead and try to hit me if you're able
Hope you know by now that mercy's off the table
Just know that by the time you are ready
I'm gonna serve you like a bowl of cold spaghetti

Cause you're not gonna win
We'll be here together
Fighting in this Judgment Hall forever
You may think that I'm weak
Nothing more than a coward
But you're the one who's hiding behind a flower

This is the end

Nyeh Heh Heh Heh Heh x6
 [bad word] on Human. Is that the best you've got?
Keep on trying.
You'll hit me eventually.

I'm so sorry, sans
It seems like I can't win
No matter how much I break him
He [bad word] right back again

But I must not succumb
The underground relies on me
The moment your blood is spilled
I will set us monsters free

Go Ahead and try to hit me if you're able
You better know by now that mercy's off the table
It doesn't matter to me how many times you try
Just mark my words, before the end of this you will die

Because I am more than a skeleton
Deep inside my soul, I hold all my friends
I hold their mercy
I hold their vengeance
I hold DETERMINATION

So just give up

Nyeh Heh Heh Heh Heh x3

Cause you know I'm stronger than you
