Multi tasking
The secret to pikmin2 is to multi task. Now, that's what the instructions tell you; these hints will tell you how to multi task .
In the valley of repose the best way to multi task is this: go drain the water with blue pikmin, and go up there with whites. Dig up the treasure and go up to where the treasure gauge points you to. Deafeat the burrowing snagret and get the other treasure that it has. Take your blues to the bridge and build it. Then, take your yellows and let your treasure gauge point you to the wooden bear. With your blues draw the firey bulblax into the water and deafet him to get a treasure.(that was a good way to get treasure fast, but each level will have a different method).
In the awakening wood, break down the gate straight ahead of you and have one ch
aracter pluck the berries. Have the other one take the blues to build the bridge behind the bulborbs. Then, take the blues and whites to the area with two bridges(one surrounded in poisen). Kill the wollywogs and build the first bidge with the blues. While there doing that go get the other charicter. After they're done have the whites get to work on the second bridge. Using both charicters get the treasure on the rocks. Kill the burrowing snagret once the whites are done with the bridge.In the perplexing pool take out fifty yellows and fifty blues. Split the blues and have only one take the yellows. Have the guy with the yellows go to the left and throw the yellows on the ledge
and guid them to the electric gate.While they're breaking it down kill the toady bloyster for a treasure.With the other guy, go to the right and continue all the way to the two scale blocks.Throw all but one pikmin on the ledge where your trying to go, throw the one on the tallest block while you're standing on it. When the yellows are done with the gate drain the water with the blues. With the other charicter Kill every enemy and build the bridge spend the rest of the day collecting berries unless you want to go to the shower room(the cave you just dug up).
