Toadette and Penelope Pitstop were both racing each other in their pink coded vehicles, which shared the same colors as the very pink girls driving them, with the duo occasionally farting as they did to provide their vehicle with more gas.
"Golly, we can be really stink!" Toadette giggled as she was bouncing about due to her frequent trombone like farts lifting her off her smelly seat.
"Well it can be tempting to have some fun and let loose when you need to give the car some gas," Penelope Pitstop spoke in her Southern accent as she was releasing bassy tuba farts to go along with Toadette's toots, the two swerving around the various twists within the grassy mountain they were heading up.
Later the two pink colored gassy girls were at the peak of the mountain, getting a vast look of the sea of trees that it overlooked. Toadette was cranking out a storm of stinky flatulence as they sounded varied, while Penelope's flatulent output was a mix of brass and bubbly poots.
"Phew... I think this was the pit stop that we needed," Penelope explained as she began fanning the air after catching a whiff of the fart gas she was making, pinching her nose with her other hand. "Peeyew... we stink like a farm!"
"Ooh, I like it when I get so stinky like that!" Toadette squealed as she placed her hands on her face, blushing in arousal. "It helps to aid the sweat I get from doing so much adventuring!"
"You go on adventures too?" Penelope asked as she bent over, causing her bubbly farts to get sloppier.
"Yeah! Why do you think I get a new batch of undies and diapers?" Toadette laughed as she moved both of her hands around, wiggling her body to make her tooting vary between squishy, squeaky, and honking.
