Ghouled Crystalyd was the ghouled version of the Crystalyd slug. Crystalyd are rarely seen Ghouled until the Earth Elemental was Ghouled making all Earth slugs ghouled including the Crystalyd.



  • The possible reason for why Crystalyds have not been seen ghouled is because they rarely surface to the ground which probably prevented them from being caught and ghouled. That was until all of SlugTerra's Crystalyds were ghouled since the Earth Elemental was Ghouled in Return of the Elementals.
