Only they and Bulbmin are able to safely traverse watery areas; any other type will only flail around in panic before drowning. They are able to perform any action in water that they can on land. If they are idle and see a nearby fellow Pikmin drowning in water, they will quickly run to them, pick them up, and throw them to shore. However, be sure to know when to call the Pikmin, and when to let the blues go for them; often whistling to them will suffice, but if they fell off a ledge, then the blues will carry them to the other, more shallow shore, which might be too far away for the drowning Pikmin to "swim".
Blue Pikmin are the last type of Pikmin discovered in all the games. In Pikmin, their Onion is found in the Forest Navel, and in Pikmin 2, 5 blues can be found near their Onion in Awakening Wood by the use of Yellow Pikmin. Yellow Pikmin are required to break down the electric fence: throw them up onto the ledge, then run around, through the water, to whistle them. There is a Cloaking Burrow-nit buried there that must be defeated. In Pikmin 3, Blue Pikmin are discovered in a new area of the Garden of Hope, after Louie steals all the player's juice and escapes from the S.S. Drake. The onion is initially buried, and Winged Pikmin are needed to pull it out of the ground. Blue Pikmin seem to be well-balanced in strength, mobility, and throw. They are often considered the most useful Pikmin, especially in Pikmin, because they can go in water, which takes up a large amount of the terrain.
Blue Pikmin are statistically more likely to be eaten by an enemy than any other type. This remains unexplained, and is in fact never even mentioned within the game.
Olimar's Voyage Log
"Deep in the cave I discovered in the forest, I encountered blue Pikmin. These blue fellows have something resembling gills on their cheeks, and they appear to be amphibious, surviving both in water and on land. The wonders of nature never cease to stun me, even in this alien land!"
 Super Smash Bros. Brawl
Blue Pikmin appear in Super Smash Bros. Brawl as kinds of Pikmin that Olimar can pull from the ground via Pikmin Pluck, his standard special move. They are the only Pikmin that don't drown in the water, are more durable than other types of Pikmin (besides Purple Pikmin), and withstand water moves like Mario's F.L.U.D.D., or Squirtle's water gun. Olimar is most likely to pull up a Blue Pikmin if he is on a water-based surface, such as a cloud or ice.
