Rotworm

''C'mon! Your rotting! See your doctor instead of fight! -every other worm''

Rotworms are a blood moon enemy that spawn in the overworld surface, or well at least supposed to. They only do so when at least one vanilla boss is killed(either KS, EOC, BOC, EOW, Queen Bee, Skeletron or the world is hardmode). Rotworms have the same tunneling speed as a giant worm, but are much bigger, fatter and juicier :D. Getting hit by their head segment inflicts bleeding. Since they have no drops, they are a pure annoyance enemy. Good luck to you and your town NPCs!
