Bat Statue

The Bat Statue is one of 43 Statues. It can be found randomly in underground caverns, and may be harvested with a pickaxe. It spawns a bat when powered. It is possible to receive hearts from them (rather ineffectively). Placing the bat statue in an enclosed box with a Dart Trap (or lava) will kill several every few seconds using timers. If you put this box in your boss fighting area, you'll need to use fewer potions.
