The Great Monster Squid Elimination Plan. Zorori and the boars take shelter from the cold weather in a fisherman's cabin. There they meet Chinku, a fisherman apprentice who lets them warm up and feeds them oden. Their meal is interrupted when the fishermen return with two other fishermen that were attack. Yo-chan, a giant squid that hangs around the harbor entrance, has recently begun attacking fishing boats. After this latest attack, the fishermen decide to take action. Their employer, Dober, demands that Yo-chan be exterminated in 3 days or the fishermen will lose their boats. Chiku stands up for Yo-chan and says he's always been their friend and he must have a reason for attacking the boats. The fishermen punish Chinku for speaking out of turn by giving him half a serving of oden from now on. If he wants full servings again, he'll have to exterminate Yo-chan himself. Zorori is outraged by this and helps Chinku out. Unfortunately for him, Gaon gets involved and now it's a competition to see who can exterminate Yo-chan first.
