Captain Toad was farting continuously because hey he's the smelly leader of the Toad Brigade; so anyway this stinky shroom boy went up to a log just sitting about and said to it: "Hey I want you to be my pooper because my pants are pooped."
Since the log wasn't sentient it became Captain Toad's plopper for the treasure tooter poured disgusting treasury out of his booty because he couldn't find enough room in his backpack to store all the gems. The other gassy Toads were chatting with each other while coming around the bend to see what their fart filled figurehead was up to, both widening their eyes upon witnessing their head honcho doing business.
"...Ahh." Mail Toad said and farted.
"Eww..." Bank Toad gawked and farted.
"Hey do you idiots mind?" Captain Toad grumbled upon pulling up his pants while continuing to fart, fanning the rotten reeking air wafted by him. "Now that I emptied my tank I'm feeling pretty hungry!"
