Sparug (スパルグ) is an enemy that first appeared in Salamander.
Sparugs are another variety of anti-body inside the Bionic Germ. Unlike Octas, they can't move around of their own free will and are rooted to their location. However, they detect nearby intruders, aim at them, and shoot projectiles to get rid of them. They are also easily cleared with missiles.
Sparug is an organic turret that fires at the player.
