Snow biome

Snow biomes are generated in all worlds created between the 15th and 31st of December, and in roughly 33% of worlds at any other time of the year. Snow Blocks are generated in place of grass and dirt, and trees have a snow cover on them; however, water does not turn into ice blocks.

Acorns can be used on snow blocks to plant snowy trees, but snowy trees drop no acorns themselves.

The Snow biome has an extremely low block requirement. Even a single Snow Block or Snow Brick will generate a light snowfall animation, although the more snow blocks there are, the heavier the snowfall will be. The snowfall animation is only generated at the surface layer.

Contrary to what their name suggests, Snowmen will not spawn in this area by default. The snow biome generates regular forest enemies and is immune to the Hallow and Corruption spread.
