Screenshots:


American Dirt Dragon: The very first stage of the Graboid life cycle, occurring immediately after the eggs hatch. A Dirt Dragon is small enough to actually jump out of the ground but they rapidly grow into Graboids.

American Graboid: Graboids are depicted as subterranean animals, superficially resembling gigantic worms or larva, with long, serpentine bodies. Graboids have a trio of long, powerful, serpent-like tentacles, which are prehensile.

American Shrieker: Shriekers are asexual, and as such only have one role, make more Shriekers, once they eat enough food they reproduce exponentially.

American Blaster: A Shrieker having achieved maturity, enters the third known phase of the Graboid life cycle: the Blaster.
