Bianca had her hands on her flatulent big butt as she farted several brassy deep pitched tuba toots, with Aria Meloetta fanning the air using both of her paddle shaped hands, the two heading down a river in a small yellow raft full of Mega Sharpedo that were preparing to rip them apart. Arceus was also on the raft, simply waiting for the action to start.
"Goodness! You always manage to build up gas, Bianca!" Meloetta stated as she was relieved that she couldn't really smell due to a lack of having a nose.
Bianca nodded as she wrapped her arms around the back of her head. "Well, I always have baked beans and burritos on me! I keep them stored in my butt!" She let out a raunchy fart so thunderous, it ripped her white dress to reveal her fart producing buttocks, with a burrito and a can of baked beans popping right out of her butt as she grabbed both gas inducing items and ate them, farting away more bassy blasts of flatulence as it caused the raft to slowly sink in the water. "Uh... oh. I think I might have gotten carried away."
"That's what you always do." Arceus stated as he began to float.
Meloetta did the same, both of the Pokemon watching Bianca sink into the river as the Mega Sharpedo all attacked her, with Bianca screaming in pain as Meloetta watched in horror, not believing what she was seeing, while Arceus chuckled, munching on some popcorn... somehow.
