The female Wii Fit Trainer was fighting against R.O.B. and the female Animal Crossing Villager in the fiery Brinstar stage from Melee, with the Wii Fit Trainer winning the match as she did various poses, much to the Villager's confusion as R.O.B. was trying to work around the fitness trainer. Silver The Hedgehog was cheering on R.O.B. in the background, standing on a platform in front of the container containing Mother Brain.
"Go, R.O.B.! You can do it!" Silver proclaimed as he pumped his arms in the air. "Show her that not everything is Wii Fit! ...Or something!" He nervously added, embarrassed.
R.O.B. noticed the rainbow colored Smash Ball, approaching it, only to be smacked in the face by the Wii Fit Trainer's butt, with her letting lose a powerful brassy fart that caused the robot to land on the top platform. The Wii Fit Trainer then grabbed the Smash Ball and performed her Final Smash, managing to knock out R.O.B. and the Villager as she won the match.
"Yeah! If you don't balance yourself, you'll never win the match!" The Wii Fit Trainer proclaimed as she pointed at herself, leaning forward to the camera as she farted out a wet toot, to go along with her entire body being sweaty from the match.
Silver could only shake his head in dismay as the Wii Fit Trainer continued stinking up the rest of the stage, of which made things even hotter.
