 * The tilt happens in 3 stages: Unstable, Partial, and Full. These can be seen in the F3 debug menu.
 * All the stages are solid except the Full stage, which is when the player falls through.
 * When nobody is standing on it, it is set to None stage.
 * The tilt can also be triggered by hitting the plant with a projectile.
 * The tilt can be prevented by powering it with redstone, but hitting it with a projectile still tilts.

 * Stalagmites break if not attached to something below
 * Stalagmites hurt entities which fall on top of them more than normal fall damage.
 * Damage is relative to height: For example, jumping on a stalagmite deals of damage, and falling from 3 blocks deals  of damage.
 * Stalactites can fall or break if unsupported, and break apart on impact, hurting entities they fall on.
 * Damage is relative to height: For example, one falling from 2 blocks deals of damage, and one falling from 3 blocks deal  of damage.

 * Powder Snow
 * A variant of snow, Entities that walk over it will sink into it.
 * Leather boots can be worn to prevent entities from sinking into powder snow blocks.
 * Players can still crouch to descend with leather boots. Wearing leather boots also allows powder snow to be "climbed", like water or scaffolding.

 * Particle of the Vibration.gif Emits particles when it senses a vibration nearby.
 * A comparator connected to it will emit different signal strengths based on what caused the signal.

 * Wool blocks between the sensor and the cause of the sound prevent the sensor from detecting the sound.


 * Spore Blossom
 * Can only be placed on the underside of a block.
 * Sends green particles downward when opened.

 * Dripstone Caves
 * A new underground biome, consisting of a massive cave biome containing vast quantities of stalactites and stalagmites.
 * Made up of primarily dripstone blocks and stone, with large clusters of dripstone blocks hanging from the ceiling, pointed dripstone on the floor and ceiling and many pools of water.
