Undyne:
Sitting here on the beach,
With my most precious peach!

Alphys: Undyne, could you maybe-

Undyne:
Alphys, I am singing!

Alphys:
This has been quite a ride,
Though I like to stay inside,

Undyne: Alphys, live a little!

Alphys: Guess I'm going out tonight,

Undyne and Alphys:
Having a wondrous time,
Here, with this love of mine,
Watching our anime,
Letting our passion shine!

Bring it on, humans!
Our love will never die!

Undyne: Give me a kiss, big girl!

Alphys: O-oh my…

Napstablook and [bad word] 
This is how our story ends
The fallen child and their friends
They stayed determined, saved us all,
An angel from heaven did call,

Gave us wings so we could fly
Out from [bad word] where we lie
Lying down in the morning sun,
We laugh as we see the sky.
