"Fight me!!!"
"No"
"common!!!"
"NO!"
"You scared!?"

Undyne's eyes narrowed as she stood in Asgore's flower patch. Oh the irony....
You, a little monster of (age) years, was currently bombarding Undyne with the current question.
"I'm not fighting a little punk like you!!"

"Awe, why not???"

"Because! I'd burrow you into a pulp!" She said, cracking her knuckles.

"You don't know that!!!"

"Fuhuhuu! You don't know either! I eat punks like you for breakfast!!"
She stuck her tongue out at you.
How scandalous!!!
How dare she partake in such an unpleasant and pride-damaging act!!

As a little punk with a big temper. You were BRUTALLY insulted.
"YEAH WHATEVER! YOU'LL FIGHT ME EVENTUALLY!!" With that you ran off, furious.

Undyne huffed, crossing her arms. "Nerd..."
A deep chuckle could be heard from farther back in the patch of flowers.
"You know, she kind of reminds me of you..." Asgore said.

"Nu-uh!"
"Mhm"
"Yeah... You're right..." She huffed, smirking. "I wasn't that annoying though."

"Oh... I wouldn't say that..." Asgore said, resting a hand on Undyne's shoulder.
"Why don't you go back and play with her for a while?" He offered.

"What? Why?"
"Because she's going to come back..."
"So?"
Asgore sighed, "she destroyed some of the flowers...." Truth be told, there was a path that had been scorched by your burning flames of passion!- aka you were a fire monster.
"oh.... Oh..." Undyne realized, looking at the scorched flowers, she glanced at Asgore, before running after the kid. "HEY NERD WAIT UP!!!"

((Sorry for the short drabble.))
