Lysithea farted and sweated up a lot of stink since she was panting due to her not being that nimble compared to Lyn and Lissa who were using their farts to propel themselves forward at a faster rate while leaving the relatively tired gassy girl behind. "How is it that you're faster than me?"
"Because while you choose not to be quite proactive we're hanging out with the various Miis to keep ourselves in good shape." Lyn explained with her doing several poses while jumping that she was able to go right back into running via her flatulence. "You just don't have the stinky spirits to influence you correctly."
"Yeah you stink, and not in the good way!" Lissa teased with her managing to show off how quick she was despite her poofy fart filled dress. "Why I can dash about like this all day!"
