The background elements are untouchable, and they refer mostly to buildings and trees. Please note that this does not include anything that spawns on background elements.
Buildings[]
They can be found only in the City and Ladybugs spawn on them. There are a variety of different buildings.
Tree[]
Cherries spawn in trees and Acorns fall from them. They can be found in Grasslands. There are different variants of this tree.
Christmas Tree[]
It is only present during the holiday season in a few locations within the grassland and arctic biomes. It is an evergreen tree with presents around the base. The presents give 2-10 gems when touched up to a maximum of 30 times per event.
Jungle tree[]
This tree spawns only starfruits and can be found only in the jungle. There are different variants of this tree.
Tree with no leaves[]
Some trees have no leaves. These trees spawn ladybugs at higher quantities than regular trees (usually) and can be found in the swamp/graveyard, and the edge of the arctic.
Coffin/Graves[]
These background elements are in the graveyard. Underneath them, there's a hole that leads to the zombie.
Volcano[]
These spawn in the demonic biome and are purely for decorative purposes. It is likely where the lava lakes come from.
Moon[]
Multiple moons are found in space. All the moons are crescents.
Since Earth only has 1 moon, this doesn't make sense in real life.
Cosmic fruit tree[]
These trees are in the space and are found on some floating islands including the large ones at the edges of the map. This tree spawns three different cosmic fruits.
Castle[]
The castle was a building. There were two of them (between the Arctic and Swamp and west of the tower). They spawned ladybugs. They were removed in the October 13, 2023 update. The Battle Arena greatly takes their shape.
Big stones/rocks[]
There are some big stones (rocks) and they spawn ladybugs. They can be found in the grasslands and on the eastern part of the jungle.
Farms[]
They are marked by fences. Pigs will spawn within the fences.
Houses[]
They are found scattered throughout the grassland areas and may have ladybugs on them and bread and worms by their porches.
Contraptions[]
They are found in the Sewage Treatment Plant, often with green lights on them which illuminate part of the area.
Snowflakes[]
During the holiday season, snowflakes fill the sky over all area west of the ocean biome with the exception of the City. They are absent from space. Over the ocean itself, the snowflakes slowly disappear from left to right. Snowflakes have a tendency to reduce game quality.
Bones[]
They are found in the Iced Cave. They are likely Mammoth tusks.
