Gonster, a being belonging to a sapient and humanoid species, possessed prominent, pointed ears and a unique feature: two heads, each equipped with sizable mouths. He resided in the Twin Hills, located on the forest moon of Endor, alongside his domesticated hoosha. This two-headed individual utilized the cured hide of a wank to fashion the magic cap, a mystical hat employed to ensnare the Raich, transforming it into a benign tree.
