[Chorus]
This facility...
Something isn't right...
Wherever could she be?
Has the doctor left to fight?

She has left this place
All her stuff is gone...
Oh, Dr. Alphys
Please, you must hold on!

[Alphys, sung]
I can't let them find me here
Not now, our final stand is drawing near!
With this brand new invention
I can end distension
And save the Underground

Now, I know what
With my robot
I must do to
Save and rescue
Everybody, I can do this!
At least, I hope so...

[Alphys, spoken]
I can't run away this time... I've just... I've got to be brave... just like Undyne would. I really hopе the human takes their timе... This isn't ready... and it isn't going to BE ready... not for a while. I need to make it as powerful as possible, and use it as soon as I can. But using it too soon would result in disaster... I'm afraid he's going to use it too early... His bravado has always been a downfall.. Come on, Mettaton, please work with me on this...
[Mettaton]
Well, here we are
The vile human appears
With your disgusting aroma
You're bringing me to tears
If you take another step
Then I know you're certain
And for a battle I can prep
And finally draw the curtain

A warning, I shall send
Before our song and dance
If you hurt any of my friends
Then I'll end you with a glance

It's time to take a bow
This show has to end soon
But now you've got one final chance
Show that you can still show love
And you will be spared
Listen to my words, and heed my advice
