Iron Hall

Iron hall is the final cave in Frigid Peaks. getting to it requires all 8 pikmin types. It's in a corridor with a loose soil tunnel blocking the entrance were you will need Brown Pikmin. There is a pool of water behind it with a few Wogpoles. with Blue Pikmin, you will want to drain it out with the drain in the center of the lake. Afterwards, There will be a Fire Gate with an Electric Gate behind it. There will be a muddy water lake behind that were you will need to make a bridge across. Behind that is a poison gate. You need to use purple pikmin to deflate a bag that needs 1000 pikmin to deflate. (this is actually easier in Pikmin 3, since Purple Pikmin have an Onion now allowing for faster collection of pikmin.) Behind this, the cave entrance is in site, BUT, a series of smoke emitters stands in the way. If you destroy these, you can enter Iron Hall...

You will want to throw a pikmin into the pit and call it back quickly. If you do it fast enough, the hermizad will fail to grab the pikmin and instead crawl out of its pit. It will realize the danger after about 2 seconds, so attacking now is crucial. stay away from the center of the pit, since once it gets back into the pit, it will almost immediately be able to attack.
