The Blood Zombie Statue is a monster-spawning statue. When wired to a Trigger, the statue will spawn a Blood Zombie. Upon dying, the Blood Zombies may drop any of their listed loot, but no coins. These statues can be found Underground.
Farming Blood Zombies spawned from the statue is a much easier way to obtain the Money Trough or Shark Tooth Necklace, rather than having to wait for a Blood Moon to occur.
During the day, these enemies are not aggressive and will not pursue the player.
