"So Mallow... tell me, how much farting did you do today?" Hapu asked as she and Mallow were walking together on Poni Island.
"A huge amount, Hapu! I tell you, I love farting almost more than I do cooking!" Mallow exclaimed as she was farting constantly while talking, smiling as she glanced back at her vibrating butt, cranking out bubbly farts as she had an aroused blush on her face, fanning the air with her right hand while having her left hand on her face. "Ooh, I tell ya... having the biggest butt to make these smelly farts is so good! I love wearing the dirtiest undies!"
"You like making your underwear dirty from your farts?" Hapu questioned as she had a puzzled look on her face, not understanding Mallow.
"Well of course! I love to get messy, why not go all the way!" Mallow then placed her hands on her butt to unleash an incredibly sloppy fart, panting as she nearly rolled her eyes over from getting so excited. "Ooh... I needed the bathroom, but after that masterpiece, I think I'm good!"
Hapu stopped in her tracks as she eyed Mallow, pinching her nose as she had her other arm wrapped around her stomach. "You just pooped your pants? Don't you feel disgusted?"
"Not at all! Being dirty feels good!" Mallow chirped up as she was still releasing wet farts, patting Hapu on the head. "Go ahead, you try, it's not all that bad!"
Hapu rolled her eyes as she shrugged. "Oh, if you insist..." She then clenched her fists as she let out a raunchy fart that turned wet after several seconds, with her laughing it off as she faced the smiling Mallow. "You know, that does feel pretty good."
"See? I told ya!" Mallow exclaimed as she and Hapu then aimed their smelly butts at each other, both of them farting brown stain making poots at each other as they were definitely going to need new pants and underwear, with the two standing on an edge overlooking the grass below them.
Hapu was quite surprised that she wound find herself farting up a shit storm with Mallow, but given how easy going the grass type trial captain was, it kind of seemed easy for her to overlook it. After all, clothes can get cleaned up, and certain types were made to get dirty... what's a few stinky farts?
