Capture Beast
this bio-engineered creature was used by the Yuuzhan Vong to round up prisoners and captives in such a way that they were relatively unharmed. The capture beast resembled a 200-meter-long, segmented caterpillar, and it moved about on one hundred pairs of sucker-tipped legs. The sucker tips were used to grasp their quarry and herd them into a specific location, where the capture beast then used its mouth to grab its own tail, creating a living perimeter that was nearly impossible to escape. If a being did try to climb up and over the capture beast's four-meter-tall body, they were simply grabbed by a leg sucker and deposited back on the ground.
