Giant Worm

The Giant Worm is an enemy which tunnels through the ground in the Underground and Cavern layers to attack the player. During a Blood Moon, it can also burrow through your house. It makes a distinctive shuffling sound that grows louder and more rapid as it approaches the player, providing a crude indicator of its location and proximity when unseen. It also leaves behind a subtle particle effect in its trail, revealing its location and direction. The head is more vulnerable to attack than the body or tail, but also does more damage.

Drops
As with all worms, its drops are for a single segment (there are 6-8 segments in total). Killing one segment will instantly kill the whole worm, leaving you with only one drop. Destroying several segments simultaneously (with Explosives) can yield multiple drops.
