Ambient entities

Backgrounds are images that appear behind objects and blocks in each biome. They are not interactable. Each biome has its own set of backgrounds that usually show a landscape of the biome. In a world, each biome is randomly assigned a backrground from its own set, and that background is permanently that biome's background unless a World Globe is used in that biome.

Ambient objects are things that appear in the background that are also un-interactable. They depend on the time of day, biome, and weather. Some are rare, and some are very common. They are completely uncontrollable by the player.
