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.
