The Blue Pikmin is a species of Pikmin that was discovered by Captain Olimar during his first visit to PNF-404.
Description[]
These blue variants of Pikmin are the only known semi-aquatic Pikmin to have been currently discovered. They appear to have a "mouth" in front of their faces, but its only main function is to absorb oxygen directly from the water, in a similar manner to that of fish gills. This specialized adaptation allows Blue Pikmin to live almost completely underwater, though they are still capable of traveling on land if necessary.
