The Wii Fit Trainer was on the rooftop of the Super Smash Brothers Mansion, watching the sunset transition into the night as Princess Peach Toadstool approached her, pulling up her black yoga pants as she then placed them over the Wii Fit Trainer's head, giving her a wedgie.

"Ow! Hey!" The Wii Fit Trainer exclaimed as she tried tugging her pants off her head, growling as she turned to peach. "What was that for?"

"That's for stealing my gig of being the most flatulent Smasher!" Peach exclaimed as she then slapped the Wii Fit Trainer across the face, being quite furious. "For years, I was the gassiest Smasher, with Wario being the only competition! Now I have to worry about you, and that's just not gonna cut it!"

"You're right, it won't." The Wii Fit Trainer admitted as she smirked, her arms folded together. "But you know what will cut it?"

As Peach was about to answer, she received a kick to the face by the Wii Fit Trainer, who then slammed her butt right on Peach's fart, letting out the most disgusting fart she could muster as she chuckled. Peach pinched the Wii Fit Trainer, causing her to yelp in pain as she went up.

Getting up on her feet, Peach floated as she looked up, to see the Wii Fit Trainer coming down. She then performed her Peach Bomber, letting out an explosive fiery blast of gas that caused the Wii Fit Trainer to catch on fire, the impact causing her to be blasted off the rooftop and land in the smooth green grass below.
Master Hand and Crazy Hand were coming back from a long afternoon of challenging various people on the Final Destination stage in Brawl, watching Peach and the Wii Fit Trainer battle in a match of flatulence as they looked at each other oddly, turning around to see the two girls pounding their butts against each other, with loud deep pitched poots coming out each time they collided, stinking up the atmosphere.

"This is a bit too crazy, even for me." Crazy Hand admitted as he moved his fingertips about.

Master Hand sighed in annoyance as he, too, moved his fingertips, albeit slower than Crazy Hand. "I still wonder why I allowed Peach to use her farts as a mean to attack... between her, Wario, and the Wii Fit Trainer, I don't think we can ever have a clean, peaceful mansion again..." He sighed as he and Crazy Hand entered the mansion.

Bowser, R.O.B., and Shadow The Hedgehog all left the mansion to do some sightseeing, glancing to the right to see the Wii Fit Trainer having Peach's neck stuck in between her butt cheeks, letting out a powerful gas blast every single time. The three of them looked at each other oddly, shrugging as they kept going.

"Just ignore it, guys. It's not worth it." Shadow stated as he moved his left hand about. "Believe me, I know."

"Of course we believe you. I mean, I have to deal with Princess Pootstool over there literally every day." Bowser grumbled back as he folded his burly arms together.

R.O.B. shook his robotic head as he moved his mechanical arms about. "It's not worth arguing about. Let's just leave them to stink each other up." He commented in his robotic, monotone voice.
