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.
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.
