Frozen Cave!

I really liked the idea of lush caves but i can't help but feel like this satisfies the need for new caves only in the forest biomes and in the plains So i thought that a new type of cave should be added the Frozen Caves! Frozen caves would be the frozen counterpart of the lush caves. They would generate in biomes such as the snowy tundra, the snowy taiga and the ice spikes. It would generate near the surface and would be the same size as the lush caves. I don't know what would be in the surface indicating that there is a cave underneath like the tree that lush caves have but it would could be something like a frozen rock or something like that. The waters would be frozen. I imagine a new type of stalactite and stalagmite would be added that would act like the regular ones but they would look more icy and probably dripping more water. As lush caves have moss blocks and moss, Frozen Caves would have snow blocks and snow layers. The walls of the caves could be made out of regular stone or a new type of stone, I imagine more blue like if it was frozen, and blue ice. That was my idea about the Frozen Caves. I hope you liked it!
