Statues

Since 1.1, in new worlds, there have been statues in all biomes underground. These statues represent a weapon, tool, npc, or figures. Most of the statues may be used to spawn items they look like infinitely. The trick is to take a wrench, place wires around it, connect it to a pressure pad, and press the pressure pad. If it is a bomb statue, the statue will spawn a bomb. If it is a king statue, the statue will teleport npc's to you if they may be lost. This is a great way to recover the goblin reforger, the wizard, and the mechanic from dangerous areas.
