Ice Caves

I’d love to see new cave biomes in the game, I feel like there’s a lot of potential in that department, and one cave biome I’d love to see is an ice cave. They’d be more common beneath colder biomes and mountains. There would be icicles, which work in a similar way to dripstone, and the walls would be lined with “veins” of ice. There would also be pools of water, which would have a beautiful deep blue color. No lava would be able to generate, lava would completely ruin the immersion. Also, maybe some sort of blue light source to set the vibe? Like I said, there’s a lot of potential, I just don’t want to get too specific.
