Dripstone Caves

The dripstone caves is an underground biome filled with pointed dripstone and dripstone blocks.

Description
Dripstone caves are large and cavernous, and often generate in ravine-like shapes. They are mainly composed of dripstone blocks, pointed dripstone, and stone. Pointed dripstone generates both hanging as stalactites and growing from the ground as stalagmites. On the surface of the world, this biome generates exactly like a plains biome does, but in future snapshots, it may possibly spawn in any other biomes.

Dripstone worlds cannot generate naturally in normal worlds yet, but can generate in the Single biome mode, however, even there they are still very small sized compared to the announcement.
