Fog in Lush Caves

There should be a fog in the Lush Cave biome just like in the nether. The fog would make sense as to all of the pollen and spore in the air because of all the new greenery.

The fog shouldnt be that strong and still let you see most of the cave.

I think this would be a really nice and atmospheric add to the lush caves that wouldnt really feel out of place.
