Amber was farting in a tuba since she was influenced by the bassy braps from Meloetta who of course was a musical methane maker; indeed it was quite something to hear the gassy Genshin girl's poots be amplified by the brass instrument that now had the rotten scent of eggs on it! "Ooh now I know why you like calling flatus 'tuba toots'! I sure am getting an appreciation for pooting in 1!"
"Yes it's so clear!" Meloetta cheered upon singing in tune with the fart gas blasts emitting out of her own vibrating cheeks. "All these stinky notes sound so nice from the rear!"
"Ugh you gals are gonna make me sick..." Paimon groaned for she let out a cute little poot and proceeded to faint upon getting a whiff of her cheesy stench.
