Have you ever felt like the game is missing cave biomes, or simply want to explore new ones? If so, you'll love this add-on!

Add up to 9 biomes without adding any new blocks or items. Use blocks from the original game to create unique and interesting underground biomes!
It adds a variety of cave biomes that the "Cave and Cliffs" update could have included. Therefore, the biomes added by this add-on are simple, but try to take full advantage of the potential of vanilla blocks to create new caves with a vanilla style!

For new biomes throughout the overworld, download this addon: Simple Biomes Expansion

For new biomes in the Nether, download this addon: Nether Biomes Expansion

The new underground biomes are:
Jungle Caves: a small jungle with lots of vegetation, ideal for finding large amounts of wood if you've run out of that important resource!
Amethyst Caves: a biome that resembles a giant geode, filled with Amethyst Clusters and Amethyst Buds. Monsters don't spawn here!
Pale Caves: an underground pale garden, an interesting biome that contrasts nicely with the Lush Caves!

Black Caves: a dark cave made of black concrete powder, black concrete, and blackstone. It's a dangerous place because the fog is black and dense. Diamonds and coal are more common here!
Tuff Caves: a cave made of tuff, with many spikes. It can be dangerous to traverse. Iron and copper are more common here!
White Caves: a cave made of diorite and calcite. There are large quantities of iron here!

Swamp Caves: wild caves with oak trees and giant red mushrooms; sometimes patches of water can appear!

Volcanic Caves: Made of basalt, blackstone, and magma, they have many spikes and a large amount of lava. A dangerous and difficult biome to explore, redstone and coal generate most frequently here!

Mushroom Caves: Caves made of mycelium, containing giant mushrooms, and inhabited by Mooshrooms. No hostile mobs spawn here!
