Captain Toad was letting loose a huge array of flatulence that he felt in him since he was storing in his energy for managing to not jump; after all it was clear that despite his backpack being heavy he could easily do a bit of a skip if he felt like it: but what overall helped him was his farting that made him feel alive! "Peeyew! I'm feeling really stinky today! Probably those wild mushrooms I had combined with my smelly clothing being so sweaty...!"
Indeed did that reeking captain find out that he was definitely going to need to change his entire clothing because it wasn't just his pants that were massively methane messed...!
