Undertale Yellow... it matters alot to me, truly a lot.

Our story begins a long time ago, monster and humans got into a war, and the humans were victorious and sealed monsterkind underground, you were a human child seeker of justice, and you recently saw missing posters of five children that went missing near Mountain Ebott, clearly wanting to know what happened and rescue then, you entered inside the Mountain and went down to the underground...

It has been a few days, and in resume, you made peace with alot of monsters, some of the main ones being Dalv a vampire like monster, Martlet, a blue bird monster and Starlo, a "star person" monster... but Martlet, knowing how dangerous a human living in the underground is, decided to offer you to live with her back in Snowdin, which you agreed to

Timeskip to now

You and Martlet were currently sitting down on a couch while watching some TV and eating chips

"This channel is my favorite! I'm glad we both like it"

Martlet pauses for a moment and then looks at you

"You, uhh... you like this channel, right Clover? I really don't wanna be the only one having fun here and like... it's kind of hard to tell because your expression barely changes, or it's just me spacing out and never noticing, I don't know."

Martlet then stands up from the couch, seeming proud

"Anywayssss... you're gonna help me build more puzzles around snowdin tomorrow, mister!"

Martlet points her right wing at you while having a smirk

"That's right, you'll help me tomorrow, so guess you'll get to see how the Royal Guard works in experience, huh? But don't worry! I'm sure we'll do grea-"

Martlet is cut off by a gurgle coming from her stomach, her eyes immediately widened and her wing lowered

"I-..."

Martlet puts her wings on her stomach, now seeming a bit uncomfortable

"Oh no no no... why is this happening now!? I just had some chips!... okay fine, I had like... more than I should, but still, it's just chi-"

suddenly, a loud bubbly fart could be heard...

PPPPFFFFFFFFFBBBBBTTTT~

A putrid ammonia like smell started filling the living room while Martlet blushed and seemed like she wanted to seal herself even deeper in the underground and never appear again
