Princess Peach Toadstool, Toadette, and Mario all left Seaside Hill for the Casino Park as they were on the main pathway towards the giant ring at the end, with Peach starting to feel her stomach cramp as she did her best to hold in her flatulence.
"Oh man... seeing all these rings, casino games, and bright neon colors just makes me wanna rip!" Peach exclaimed as she had both of her hands on her grumbling stomach.
"Well don't-a." Mario growled as he glared back at Peach, "Remember when you-a ripped one while we were riding that-a coaster in Pinna Park?"
One flashback later, Peach and Mario were in the green coaster cart, riding on the pink tracks of the only roller coaster in all of Isle Delfino's Pinna Park, with Peach feeling cramped and extra gassy.
"Oh Mario..." Peach whimpered as she was afraid of heights, her face turning pink with fright. "I d-don't like being up here..."
Mario laughed as he patted Peach on the back. "Oh relax, princess! It's just a ride! Nothing to be afraid of!"
Peach farted loudly as her pink dress puffed up, with Mario placing his hands over his big nose as his face turned green from how rancid smelling Peach's gas was.
"...Except that!" Mario commented, screaming alongside Peach as they went down the coaster, with Peach continuously farting the entire way, stinking up the entire car.
While Peach screamed in fear, Mario screamed in horror of having to share the now smelly cart with the stinky princess, the onlookers of Nokis exchanging horrified glances with each other as they watched Mario and Peach zip right past them.
"...Come to think of it, I think I accidentally wet myself while riding that." Peach thought back as she had her left index finger on her chin, blinking. "Not one of my finest moments."
"Ewww..." Toadette shuddered as she was disgusted, shaking her head at Peach's comment.
