In the Nuke Temperate Forest, the rock worm has replaced its ancestor. Its skin has grown thicker and stronger, giving it a darker appearance. This armor makes it very difficult for the swinging nede to break into the Rock Worm’s body. While the nede tries to crack the armor, the worm uses its massive antlers to swipe at the nede, causing the predator to drop the worm. Other than that, the worm is the same as its ancestor.
