The Alien Hero of the Underground (Ben 10 X Undertale)

Waterfall Continued

* Shyren hides in the corner, but somehow encounters you anyway.

Frisk: "This one seems shy, but not as much as Nabstablook."

Chara: "Nabstablook?"

Ben: "A ghost monster." He hits ACT, then Check.

* SHYREN - 7 ATK  2 DEF
* Tone deaf. She's too ashamed to sing her deadly song.

Shyren doesn't say anything other than "hum hum", before sending out a few attacks in the shape of a music note, which doesn't come close to Ben or Frisk.

* Shyren thinks about doing karaoke by herself.

Chara: "I'm curious as to what it meant by "Deadly Song"."

Frisk: "Let's hope we don't find out." She hits ACT, then Hum.

Frisk hums a bit, which makes Shyren follow the hum as well.

Shyren: "Si re, si re, si mi, si mi."

Shyren sends out much more music notes than last time, but it isn't a problem for Ben or Frisk, since they're pretty easy to dodge.

* Shyren seems much more comfortable singing along.

Instead of just ending the battle, Frisk decides to hit ACT and Hum again. She continues to him, with Shyren humming along. This causes more monsters to show up, with the whole thing becoming a concert of some kind.

Ben: "Frisk, what are you doing?"

Frisk: "I'm having some fun." She puts her hands on her hips. "Got a problem with it?"

Ben: "Nope, just curious."

Shyren is humming along, but much louder and more confidently.

Shyren: "Si Fa, Si Fa, So Fa So, Mi Re Re."

Shyren does the same attack, which Ben and Frisk avoid easily.

In the background, the three humans see that Sans is selling tickets. All of which are made of toilet paper.

Ben: "Guess he found a way to start paying off his tab."

Chara: "No wonder he was charging 50,000 Gold for people to use his telescope."

Ben decides to join the fun, and he hits ACT and Conduct. Ben starts waving his arms wildly while Frisk and Shyren hum and the crowd eats it up.

Frisk: "Now what are you doing?"

Ben: "I can't let you have all the fun."

Frisk giggles as she continues to hum with Shyren.

Shyren: "Si Fa, Si Fa, So Fa So, Mi Re Re."

Shyren, again, sends the same attack that Ben and Frisk dodge easily.

Chara: "You guys seem to be having fun."
