Drutash grubs were small creatures which resided in caverns on Sullust and were considered a delicacy by Sullustans. They were offered as a reward to Keyan Farlander for rescuing Sullustan prisoners from the Galactic Empire. During the rule of the Eternal Empire, excretions from the grubs were used as folk remedies for parasitic infections like Rodian rot-worm.
