Dragon-slug
an unusual creature found only on Hoth, the dragon-slug was a fire-breathing worm which consumed lumni-spice as food. It created huge tunnels in the rock and ice as it searched for the spice. It was for this reason that lumni-spice was rare and difficult to harvest. The average dragon-slug could attain a length exceeding fifty meters, and lived a solitary existence beneath Hoth's ice. The body of a dragon-slug was covered with an armor-like hide, and it moved about on vestigial legs that could be found every three meters or so along their bellies.
