Ambient objects - Official Terraria Wiki

Throughout most biomes and layers, various ambient objects are randomly scattered on world creation. These are naturally-placed background objects that can be broken with a pickaxe or drill, but otherwise cause no effects, and do not drop items. They function primarily as visual ambiance and cannot be collected by players, and unlike several other naturally-generating objects, cannot be crafted with the help of Ecto Mist. Apart from icicles and Jungle plants, ambient objects do not regenerate over time.
