The Mutated Lush Caves

I think there should be a rare cave biome like the ones on the surface. The M Lush Caves is going to have "mossy" mobs in them and then a mimic mob that is a Carnivorous fly-trap disguising as one of the dripleaf plants. The Mossy mobs i am talking about is the ones from Minecraft Dungeons (The mossy Skeleton and The jungle Zombie), and the Mimic will be a new stationary mob that stays in the same block where it spawned, or just basically act like the shulker (except the teleportation and shulker bullets part). If you devs wanted, you can also add the Whisperer, the quick growing vine, and the poison quill vine from MC Dungeons. The chances of this cave biome to spawn should be as rare as the Badlands or the Ice Spikes or the Mushroom Island biomes. "If" we added the Whisperer from MC Dungeons to the M Lush Caves, then it will be a cool exclusive mob to the biome and also act like the Warden of the place. I just think we should add this to have a little reference to one of Minecraft's other game (MC Dungeons). You might say we have a reference of the Glow Squid which is from MC Earth, but i just think it'll be cool if this was added too. Bonus : you should be able to mix cocoa beans with milk buckets to make Chocolate Milk, there will be no bonus effects, the feature will be just for fun.
