Thom's Mod

Players who want more variety while exploring and building can use the new block types, including vertical slabs that add more shapes to existing blocks. The content centers on world generation: around ten new biomes with their own structures, plants and mobs, along with new animals such as elephants and penguins. Some hostile and neutral mobs, including wizards, mummies and ghosts, add combat variety.

Crops, trees and decorative blocks expand the options for building bases and homes, with more than twenty crops and more than twenty trees. Food items come with additional status effects, and a wearable backpack provides extra inventory space. Wearable banners let players form clans or teams. The mod requires the TerraBlender library, which must be installed alongside it. Files are published for 1.18.1, 1.18.2 and 1.20.4 under the MIT License, and the code is not open source. The latest Forge file targets 1.20.4 and was released on 2026-09-30.
