This enemy is extremely weak and generally not a threat. While it can attack pretty quickly, it only deals 1 damage. It is spawned by the Red Roundhead Drill, however, which can lead to quick and annoying mobs of them. While it has rather low HP, it keeps digging in the ground making it out of access unless using piercing weapons. It is an efficient EXP and Gold grinder; keeping the Red Roundhead Drills will make them continue to spawn enemies until they can't spawn them anymore, which averages to about 100 enemies killed per screen. It's size can make it hard to hit.
