But did you know? There's a tale with that girl, I'm about to unfurl: 

Long long long ago, underneath a part of the world, an unknown couple birthed a fish, a most beautiful monster girl
Then Asgore took her in and the rest is all history, she was taught to fight, train, and love, one day vanquishing misery

@ You have to be the very best
& Training all of dusk to dawn

@ Never give up Never give in
& The royal guard I'll soon [bad word] 

@ You will be put up to the test
& Anything for you my liege 

@ The only word you know is Win
& There's nothing that I can't sieze

But then came one with a heart that shone like a sun, changing everything that she's known of those pitiful humans

No ones been hurt, and this girls souls [bad word] key, will Undyne the warrior waver or fight so unrelentingly?

@ Capture humans that we seek
& Just one more and we'll be free

@ They have all forsaken us
& Why is this girl being nice to me?

@ Just make sure that those you love
& She [bad word] away in fear?

@ Are protected above all
& Hey you [bad word] back here! 

 [bad word] away whistling

Known as the hero, the one that's unbeatable
with a swipe of that spear, the shining leer, you’ll learn to fear
Mightiest in the land, happy to lend a hand, 
Everyone’s a fan of Undyne.
