X Spawn

Unidentified Life Form 76 (Metroid Fusion) is a type of Hornoad nest encountered in Sector 1 on the Biologic Space Laboratories research station. The structures resemble squat, pulsating, cylindrical brown objects similar in shape and function to Air Holes. They exist in the background of most of the "natural" rooms within Sector 1, and will spawn a seemingly infinite number of uninfected Hornoads, which can then be infected by free-floating X Parasites. No such structures are ever seen on SR388 itself.
