Captain Toad was farting and screaming for his life because King Kong and Godzilla were having yet another legendary showdown, with the godly kings causing a massive panic within Hong Kong. Captain Toad noticed that he was accidentally dropping the various artifacts he collected on his treasure tracking, with him nearly blasted by Godzilla's radioactive breath lighting up the mushroom methane into a huge red and yellow burst of flames, the fiery result causing various skyscrapers to burst into fire.
"Wah! Why did I think coming here with these kaiju Titans dealing damage to each other was a good idea!?" The unlucky leader of the brigade complained for the Toad was almost crushed from Kong dropping various vehicles around in an attempt to nail Godzilla, with the fungi man farting his way from the damage. "If I knew this would be so colossal I would have stayed home!"
The ear piercing roars of Kong and Godzilla caused windows to shatter, with Captain Toad crying for his farts provided enough room for him to blast away into a nearby pipe that managed to save him from the entire city collapsing, with the monsters taking their battle towards the China mainland.
