Blue Lums resemble blue-colored Yellow Lums. They are found only underwater.
Blue Lums are the manifestation of the life force of the Glade of Dreams. When a baby is born it is given its first Blue Lums. These Blue Lums are kept until the time of death.
Role in the Games
Blue Lums are found only in underwater areas, with the exception of the latter half of Whale Bay. If Rayman approaches one, his air meter will refill (similar to a Red Lum in relation to the HP meter). Blue Lums regenerate after a few seconds.
Mysteriously, Blue Lums were not included in Revolution. Replacing them were bubbles rising from holes in the submerged ground.
In the Game Boy Advance version of Rayman 3 and in Rayman: Hoodlum's Revenge, Blue Lums give Rayman the ability to fly for a short period of time.
