Algae Men were Dr. Sydney Moist's henchmen, who appeared in the episode "The Evil Beneath" of the Jimmy Neutron series. They are large green humanoids.
It was later revealed that Sydney was using a mutagen to turn innocent tourists into algae men, which explains the rash of disappearances in the Bahama Quadrangle.
