Blue Pikmin, as their name implies, are a blue species of Pikmin that reside on PNF-404. Besides coloration, these Pikmin are distinguishable from other Pikmin species by their mouths, a trait seen in no other Pikmin species. These mouths are used to take in water, which filters oxygen through the gills located on their cheeks. This gives them the astonishing ability to live their lives completely underwater. Producing more Blue Pikmin can be easily done by dragging nutrients or animal carcasses to the Onion or by throwing other species into a Lapis Lazuli Candypop Bud.
