Captain Toad was farting a huge amount of methane to keep himself nice and warm since he had reached the tallest peak of a mountain he was climbing; he could get a good look at the various valleys he had trekked across to obtain the special gems that he had sitting around with turnips in his backpack; and he was quite happy since he had been ripping ass the entire time to keep himself motivated to go though the giant region. "Peeyew! I really reek! Better hope I could find fresh undies while I'm up here! I'm really stinky!"
"Always with the farting..." An older looking Toad complained while sitting on a bench nearby just taking in the surroundings. "...Can't you just learn to let go?"
"You should take your own advice!" Craptain Toad boasted upon slapping his farting dump truck. "Cuz I'm not stopping!"
"...But don't you find that to be-"
"I find it very fun to due do thank you very much!" Braptain Toad laughed while his farting got bassier. "Why if not for my farting I wouldn't be the Toad Brigade captain!"
