Additional 5 Minute Clip with a Giant Crab!
Unfortunately this is just the last few rounds of the game (20 minutes worth) + a 5 minute clip but the full episode should be 40 minutes.
Each member of the cast sit in a row and cycle round passing a fan. Each time they get the fan or live crab, they must say a word relating to a certain theme, then pass it to the next person. They have to remember that word, plus add their own that fits the theme before passing it on. And so it goes around and around with the ordered list of words to remember getting longer and longer. Those who can't remember correctly get a surprise batsu.
Even the game hosts aren't safe though as Matsumoto finds.
