These biomes were very common during autumn (v2.0.5), while they can still be found, they are much less common.
- It consists of Chestnut Trees, Pumpkins, Violet Dirt, Pale Brown Dirt, Sunflowers, and Pomegranate Trees.
- During version 2.0.5 you could sometimes find Cornucopias filled with Thanksgiving themed items.
