Added decorative blocks for the upcoming lush caves: hanging roots and rooted dirt!
Added moss!
Added spore blossom!
Cave vines and glow berries
Cave vines grow down from the ceiling, like weeping vines
When they grow they have a chance of producing glow berries
Glow berries are a natural light source as well as a food source
Foxes eat glow berries
Use glow berries to plant new cave vines
Bonemealing a cave vine will create glow berries
Dripleaf
Small dripleaf needs moisture, so it grows on clay or underwater
Small dripleaf grow into big dripleaf when bonemealed.
Big dripleaf grows taller when bonemealed
If you stand on a big dripleaf it will tilt after a while and you will fall off
You can crouch or jump to prevent a big dripleaf from tilting
A tilted big drip leaf will tilt up again after a while
The big dripleaf will break when hit by a projectile
The wandering trader will sometimes sell small dripleaf plants
Moss
Two new decorative blocks: Moss block and moss carpet
Moss carpet can be crafted from moss blocks
Spore blossom
A beautiful large flower placed on ceilings
Particles drip from it
Changes in 21w05a

The stages of copper oxidization are now called "Copper Block", "Exposed Copper Block", "Weathered Copper Block" and "Oxidized Copper Block" in sequence of least to most oxidized
Drowned now have a chance of dropping a copper ingot, they no longer drop gold ingots
