Thinner whuffa worms were hunted by the clans of Dathomir in extensive rituals. The clans on Dathomir used their skin to make their armor and dried hide as rope.
When Han Solo was on Dathomir, he was included in one of the whuffa retrieving rituals for the Singing Mountain Clan. Also when Nuru Kungurama, Lalo Gunn, the Blackhole Pirates, Proffesor Groob (and his family) and the Breakout Squad were escaping Plunder Moon in an Infinity Gate they were attacked by a whuffa worm but escaped.
