YUNG's Cave Biomes (Forge/NeoForge)

YUNG's Cave Biomes is a vanilla+ mod that adds two new cave biomes to the game, the Frosted Caves and the Lost Caves! Each biome features the addition of a new mob, new blocks, items, music, and more.

YUNG's Cave Biomes is intended to be fully compatible with every mod, including other worldgen mods. Any known incompatibility notes will be mentioned here. If you encounter any compatibility issues, please let us know in the Discord! 

Optifine:

• The thick yellow fog won't render during sandstorms. Still looks good, just not as cool of a visual effect.
• Enchanted Ice is visible even when embedded in ice. Doesn't really affect gameplay.
