"...Come on... ...you can do it...! ...Just push it all out...!"
Samus Aran farted as she bit her lip, bending over in her tight zero suit as she had her hands on her knees, forcing as much bad gas out of her big butt as possible. Wii Fit Trainer farted alongside Samus, both of their farts being loud and deep pitched as Wii Fit Trainer's yoga pants got darker. Now being in the freezing, generically named Summit that was farther north than any stage used in Smash Bros, the girls were warming themselves up with flatulence. Peach and Zelda still had their tight jeans on.
"Y-you know, I was never one to flaunt my gassiness..." Zelda commented as she had her hands on her butt, letting out a wet poot that got raunchier with every passing second as she sighed of relief. "But oh, does it feel good to let them out and warm you up..."
Peach had her arms folded, warmed up, but from jealously instead of gassiness. "Ooh, who cares!? I just want this Wii Fit Trainer dead!" She then stomped over, performing her Peach Bomber on the Wii Fit Trainer as the farting hearts knocked her down the summit.
Samus and Zelda looked down in shock, with them and Peach all farting in unison as Wii Fit Trainer came back up, literally farting to fly around.
"Did you think I would allow myself to get taken down so easily like this, Toadstool?" Wii Fit Trainer commented as she then smacked herself into Peach, her butt on top of the jealous princess. "It's a good thing I allowed Wario to show me a few of his tricks... including this helpful move!"
With a grunt, the Wii Fit Trainer performed the Wario Waft, strong enough to send Peach blasting off again. Zelda and Samus literally pooped their pants and suit respectively in shock as Wii Fit Trainer stretched, proudly farting louder than before to signify her victory.
Only bad thing was that this caused the summit to melt, causing all three girls to fall into the cold mountain below, tumbling down towards the freezing cold water.
