Greater spit-crawlers were a species of parasitic worm that dwelt within the naval passages of members of the happabore species. Infections of the parasite in happabores could be treated with Happy-Bore Medicated Dewormer, a product produced by Galacti-Stok which contained Trestibinexocycline 5-Gamma, thlank oil, greel-root acid and forage products. Use of the dewormer on greater spit-crawlers was suggested in the instructions for the product. Lesser spit-crawlers could also be found in happabore naval passages and treated with the dewormer.
