They have one hour to finish the hot pot and the noodles, and the team that eats more or faster wins. The match is very close, with both sides using various strategies and tricks to eat more. In the end, Egashira's team wins by a small margin, and Masubuchi has to say "UMASHIRA" (very yummy) in her next TV show.
