Caves and Cliffs:More Bio-luminescence in Caves

These would be cool underground lighting,and would glow either bio-luminescent purple or bio-luminescent aqua(like glow squids),and would emit light in a 3 by 3 by 3 radius around them that is the same color that they are. They are all under Y=-8

Glowing Moss Fungi(aqua):These would be mostly in the Deep Dark,and when the lights dim,instead of dimming,they would stop emitting light.

 Glowshrooms(purple):These can be randomly found,as long as they're found with normal mushrooms.

 Glow Kelp(purple)/Glow Seagrass(aqua):Found anywhere in Deep Oceans and Cave Oceans.

 Bio-luminescent Cave:This would be a biome found under Y=-8,and would be a biome that you can find all the bio-luminescent creatures and objects. This place would be less for illuminating deep underground,but more of a beacon to show you a relatively safer place,as no monsters but the Glow Slime are found down here. You can get some glow out of it though,but if you try to build a house,you'll find there isn't much real light here,it's just a place that glows.

 Glow Slimes(either):These would be in Bio. Caves,and would drop some Glow Slimeballs to make fun Glow Slimeblocks.(drops its color)

 Glow Grass/Glow Shrub/Glow Vines(all aqua)/Glow Cover(purple): Found only in Bio. Caves as plant life. Glow Cover grows on the top of deepslate like top snow and moss,Glow Shrub is a bush that can maybe have some sort of Glow Leaves,Glow Vines are like normal vines,and Glow Grass is grass...
