Bryyo spores (as named in Metroid Prime 3: Corruption game files) are floating spores found in large groups in the skies above the Fiery Airdock and Thorn Jungle Airdock on planet Bryyo. They resemble clusters of glowing sticks/branches. Although they can't be scanned, they can be shot, resulting in a small explosion. They seem to be the Bryyonian equivalent of birds on Tallon IV. It is possible that these spores are produced by the massive fungi of the Bryyo Thorn Jungle.
