underground biomes

Ithink we should have a lot of underground biomes like underground forests (Underground jungles) that would have upside down trees and demented trees and lots of lava (for light) and The Mycosphere - a challenging new Underground biome and Radioactive Plains (was: Underground Biomes) and also some Underground Rivers and there would be Underground villages and Goblins villages and Goblins tribes (The Goblins) and also there would be other mobs too like other monsters and a speical type of goblin called a madaguan that would steal from eachother and you and hit eachother and you and do mean games or lie and basically be very bad goblins. then, there would also be a speical ore that would have strength between stone and iron but have sharpness/effeicency between iron and diamond. Also the underground caves would have multiple underground forests and cave biomes (like deep dark or lush caves) at once.
