Speaking of Pikmin, how do I beat those 2 birds in the Forest of Hope? (First game)
Well basically you just chuck your guys onto their faces. The best bet is to wait around until it "drills" out of the ground then quickly swarm it with the C-stick. Yellows are also handy since they fly the highest.
Oh, and please note you only need to kill the bird at the very edge of the area as he has the ship part inside him.
...I consider myself to be a bit of a Pikmin expert.
