Further developing into their fossorial lifestyle, (which merely consisted of digging and scooping), they have greatly reduced in size to avoid collapsing their burrows. That being said, they still are quite massive at 100 meters. They have become rather serpentined, elongating and flattening out a bit to make maneuvering in their burrows a lot easier. They have also changed coloration to avoid predation, and while the specimen pictured is yellow, they can switch colors to brown when in areas of dense Recycler of Worlds's fecal matter. Due to them being in a darker area, they have lost some of their eyes and replaced some of them with infared detectors, being able to see heat. This allows it to avoid predators and also find sweet, nutritious Recyler of World's fecal matter veins.
