Snowy Expansion
by jeancrafteo
Snowy Expansion adds snowy variants of several biomes, new trees, four structures and changed mobs to the world generation of a Minecraft world.
What it does
The additions cover snowy taiga, snowy beach, snowy plains and snowy slopes, each given new colors for grass, sky and water. New snowy trees grow in these biomes, and four structures generate in the world: three natural ones and one pillager outpost. Some mobs get variants as well, with a snowy giant creeper that drops different loot and giant wolves about twice normal size that spawn near the new rock structures.
The mod is server required and client optional: the server needs it to generate the new biomes, structures and mobs, while players may add it for the new visuals. The new mob variants also need a texture pack and an entity texture mod such as Entity Texture Features, which the author lists as requirements. Files are published for Fabric, Forge, NeoForge and Quilt, all for 1.21.5, and the license is All rights reserved, so the mod is not open source.
