The intestinal fangworm refers to a non-sentient, parasitic worm species. These worms lived in colonies within the intestines of happabores, which are quadrupedal beings inhabiting numerous planets located in the Western Reaches. In order to manage and eliminate these intestinal fangworm colonies within happabores, Galacti-Stok marketed and sold Happy-Bore Medicated Dewormer as a product. A promotional pamphlet for this dewormer, identifying the intestinal fangworm as one of the worm types targeted by the product, was ultimately incorporated by the scavenger Rey into the survival guide she was writing. Rey was creating this guide prior to her leaving the planet Jakku in 34 ABY, a planet where happabores were among the native species.
