Ambient objects

Throughout most biomes and layers, various ambient objects are randomly scattered on world creation. These are placed background objects that can be broken with a Pickaxe, but upon doing so do not generally drop any items or cause any other effects (though destroying some ambient objects in a surface Forest biome has a chance to spawn Worms or Grasshoppers). They function primarily as visual ambiance and cannot be collected or placed by players.
