Lyrics:
Flowey:
You know what's going on here,
Don't you?
You just wanted to see me suffer.

Toriel:
Y-You really hate me that much?
Now I see who I was protecting by
keeping you here.
Not you...
But THEM.

 [bad word] 
HALT, HUMAN!
I, THE GREAT [bad word] 
HAVE SOMETHING TO SAY.
YOUR LIFE IS GOING DOWN
DANGEROUS PATH.
BUT... STILL...
I BELIEVE IN YOU!
YOU CAN DO LITTLE BETTER..!
EVEN IF YOU DON'T THINK SO.
I...I PROMISE.

Undyne:
If you get past me,
you'll destroy them all, won't you?
monsters...humans... everyone.
vanquished in an instant!
But I won't let you do that.
If you think I'm going give up on hope,
you're WRONG!

sans:
it's a beautiful day outside.
the birds are singing
flowers are blooming...
on days like these
kids like you...
should be burning in [bad word] 

♪CHARA:♪
When I fell from above
to the underground,
I soon discovered
there were monsters around.
But after time had passed,
it was easy to see...
the only [bad word] monster down here was
ME.
Let's delve deep
into the deeds of my past.
Told Asriel
I'd be a friend that would last.
It's easy to misjudge a little human
like me,
who wants to destroy
all of humanity!
He absorbed my soul,
all according to plan.
Now, no one can stop me
not monster or man.
But Asriel failed me
way back when.
And with your help, Frisk...
I CAN TRY IT AGAIN!
Let's erase the underground!
All their fears and [bad word] [bad word] #33;
Let's erase the underground!
Not a single soul gets through!
Let's erase the underground!
Erase the underground!
♪
LET'S ERASE THE UNDERGROUND!
ERASE THE UNDERGROUND!
ALL THEIR FEARS AND [bad word] [bad word] #33;
LET'S ERASE THE UNDERGROUND!
♪
NOT SINGLE SOUL GETS THROUGH!

Asgore:
You must be the one that flower
just warned me about.
What kind of monster are you?
Sorry, I can not tell.
Now, now!
There's no need to fight.
Why not settle this over
a nice cup of tea?

Flowey:
See? I never betrayed you!
It was all a trick, see?!
I with with you and here for you!
N-No! It's me! Your best friend!
I'm helpful! I can be useful to you!
I promise! I-I won't get in your way!
I can! I-I CAN!!
PLEASE DON'T KILL ME!!!

Chara:
Greetings.
I am Chara.
Thank you.
Your power awakened me from death.
Let us erase this pointless world
and move on to the next.
No?
Hmm.
How curious.
You must have misunderstood.

SINCE WHEN WERE YOU THE ONE IN CONTROL?
