Corrosive Caverns - New Cave biome

In this biome everything is the opposite of lush caves. New Blocks: Dead Moss, Dying Vines - These vines give a faint green light like glow squids, Corroded Spore Blossoms, and Red Sand. New Mobs: Corroded Warden- Can Not hear as well as normal warden but has a stronger attack and health. Water in this biome turns a tint of orange ( Like swamps). This biome has more iron and copper than any other. Just like Mesas that have gold, this biome has a lot of iron and copper. Instead of abundances of clay, there are abundances of terracotta. These caves have a chance of spawning a corroded dungeon which is a very hard dungeon underground which may have: Enchanted mobs, A Corroded Warden, and many rooms to defeat. These dungeons have better loot chests the lower you go, maxing out at three floors underground. I feel like dungeons need an update as they are very easy to defeat. Also I would like to have more cave biomes. This cave biome is rare and will never spawn near a lush cave. There could also be a corroded skulk sensor which can only detect item drops. For example it cannot detect mobs but dropping an item can be detected. There is also a slightly higher chance to spawn fossils in this biome.
