Thousands of breeds of fungal crawlers exist across the world, varying in appearance and habits, but all share a few common features. They invariably appear as monstrous crickets or locusts fused with fungal growths, often topped with mushroom-like caps. This hybridization makes them adept survivors, and infestations are notoriously difficult to clear out entirely. Their needle-like teeth cannot chew solid food, so most fungal crawlers rely on digestive enzymes injected through their bite to make their meals palatable. Average specimens grow to 30 pounds and 3 feet in length. They reproduce by releasing spores, which remain viable for decades until they contact organic matter and eventually develop into small, pale grubs.
