From Junk Jack Wiki
The Winter Biome is a new above ground biome added in patch 1.0.4, and consists of O-Spruce Trees, O-Snow Blocks, O-Snow Covered Blocks, O-Ice blocks and O-Cold Dirt.
The biome was added intentionally to provide a Christmas feel to the game.
- Upon cutting down pine trees, the trees drop wood and Spruce O-Saplings.
- Snowmen are crafted from snow using a snowman head (found in presents), spider legs and snow.
- Hidden in the underground are Christmas Tree statue pieces and Christmas Presents.
