Waterfall Man on the Internet

[MONSTER KID]
Oh wow, this is so cool! I've never had a friend like you before! Come on!

Through the water, two best friends go in!
Through the thick and thin
We'll go arm-in-not-arm!

You can hold things, and I can, uh...I can give a boost! It'll be great! We'll get to Undyne in no time! Just the two of us!

Every monster, wishes they could be
As great as Undyne
With her power and charm!

Or maybe it's just me
Mom says I have an unhealthy obsession, and project a lot!
What do you think?
Do you think she's cool? Or should I just-

[UNDYNE]
STOP RIGHT THERE, HUMAN!

[MONSTER KID]
Human? Where?

[UNDYNE]
Seven. Seven human souls
And with yours, we can-
HEY! GET BACK HERE!
Quit running and face your death like a man... woman... child?
