Fangworm

Fangworms were a species of parasitic worm that lived in colonies in the intestines of happabores. 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 intestinal fangworm colonies was suggested in the instructions for the product.

Behind the scenes
Fangworms were first mentioned in Star Wars: Rey's Survival Guide, a replica journal written by Jason Fry and released in 2015.
