New Swamp Structure + Swamp Mobs: Murky Mines

A cave update is coming to Minecraft, and I think a cool structure you could be able to find in caves under swamps could be the Murky Mines. These could look like mine shafts, or something completely different. Inside of these mines could be Fungologers, mushroom-themed illagers that can summon evil mushroom minions. These would chase the player around and inflict poison. Maybe there could even be some sort of mining illager found in the Murky Mines, a Minologer, that would use pickaxes to mine ores to collect. Minologers could be very powerful and dangerous, but if you give them a pickaxe or mineral, they will become passive towards you. Maybe they could even be mining for some sort of swamp-themed mineral that you can only find in underground swamps.
