Toadette was merrily skipping in the Mushroom Gorge, heading towards the starting line as she got knocked into the air by a blue shell explosion. Toadette screamed as she quickly spun her pink pigtails, flying in the air as she looked down, to see several spiny winged blue shells zipping across the track forward and backward, causing massive explosions as screams were heard.

"What in the world?" Toadette exclaimed as she was in shock, her jaw dropping as she shook her head. "Who's causing all of these blue shells to pop up out of nowhere?"

Nearby the curve leading towards the finish line was a blue shell generator, which was constantly pumping out blue shells like there was no tomorrow. Wario and Waluigi chuckled as they rubbed their hands together deviously, having plotted the chaotic nightmare that was occurring on the track.
