The Nisokuhokō gū-mono are found at the Sandy Hideout. They are in the Unknown family and are about the same size as Purple Pikmin. Once you've defeated all 100 of them on field, their bodies will combine into a big beast that can use it's arm as a whip, throw its victims around, flatten them, demolish them and even hug them to death. Oh, and, it's surrounded by 250 Nisokuhokō gū-mono. Once defeating them all, they will collide for a final time making themselves the size of 350 Purple Pikmin. It can now make Sonic Booms with its arms and Flop. It can also shoot electricity from its hands, breath fire and attract water which can then turn to ice. The best choice is to take Elemental Pikmin or Bulbmin or Blue Bulbmin into battle.
