nether update mirage biome

A biome that looks mysteriously like the overworld with lush green vegitation growing on the walls and mud on the ground with moss growing on it would be very interesting. You could add some special passive mobs that look like animals from the overwoorld but with some differences. The biome could be very rare and grows inside cracks in the walls of the nether. This biome would make the nether more interesting and mysterious, and would inspire people to explore the cracks in the nether for this special biome. The color scheme would be very saturated and the biome would have special water that can survive in the nether without evaporating.
