Glow Worm Caves

Glow worm caves would be a new and captivating cave biome. It would feature a glowing ceiling (The glow worms), and glowing liquids. It would look like your traversing a starry void. Some blocks in the ceiling would have wiggling worms poking out of them. And the glowing liquids would drop from the ceiling as particles. I think it would make for a unique and very exciting find deep in the dark caves.
