Worm AI

Creatures with worm AI typically follow one distinct pattern. Worm AI creatures: Burrow through all brick types, have a linked body usually consisting of a head, several body pieces and a tail, each with it's own amount of life points, turn at angles which allows them to target and charge the player, suffer no damage from suffocation or lava, are killed if one segment is destroyed, produce a distinct burrowing noise.

The exception is the Eater of Worlds which splits into multiple worms instead of dying when one segment is destroyed.
