Hushims

Footage of one

Hushims are sold for 30RU at Maelnir Trading Ships. They are a sand worm that lie in wait in the ground. Their location is marked by a circle of rocks. When a planet lander moves around the circle of rocks the Hushims will erupt out of the ground and destroy the planter lander. Not all circle of rocks have them. Some Hushim ambush locations bait you with a crate.
