Giant Worm (Caves and Cliffs)

Spawning below y 0 this giant mob(probably around 4 blocks thick and 10 blocks long) would be a constant threat within the caves. These large worms would be able to go through blocks, much like a silverfish as to not destroy player builds. A way to combat worms constantly going through your base is to place spore blossoms, which deter the mighty creatures away. The worms drops could help with making lesser torch alternative within the deeper caves.
