Venum Bulb

Venum Bulbs are plants that can be found growing in the Underground Corruption/Crimson once Hardmode has been initiated. They are slightly harder to find than it is to find Life Fruits in the Underground Jungle. If broken with a Pickaxe or Drill, The Blight Queen will spawn. They are relatively easy to spot, as they emit a faint, purple glow.

Trivia

 * The word "Venum" is a combination of the words "Venom" and "Venus", the latter likely referencing the Venus Flytrap plant.
