The mine song if it was by Chara. Not actually part of Pentale. Enjoy.

Toriel just died.

Papayrus was not far behind.

Shyren soon,
And Temmie to,
They die die die die.

Undyne just died,
Even after coming back to life.

Can't you see,
That I can't be beat,
Your soul will soon be mine.

It's all destroyed by me,
Everything that I see.

Ruins, Snowdin, and Hotland.
Everyone there,
Has faced destruction.

They have all died.

And as of this instrumental break,
Mettaton died.

The Underground and surface will die.

Flowey will also die.

It's what you wanted,
You're the one who chose it.

And now, your soul is mine.

Reach the surface and they die.
