Coral

Coral is a type of non-solid block that comes in five variants: tube, brain, bubble, fire, and horn. It is the only animal along with sponge that is a block and not a mob.

Dead coral is the dead variants of coral.

Breaking
Coral and Dead Coral can be mined instantly but can be obtained only when mined with a Silk Touch enchanted tool.

Dead coral can only be obtained with a Silk Touch pickaxe.

Natural generation
Coral naturally generates in coral reef structures found in warm ocean biomes.

Post-generation
When using bone meal on dirt, coarse dirt, sand, red sand, gravel, or clay in warm ocean biomes, coral generates in place of some of the seagrass. In Bedrock Edition, the same can happen in any biomes as long as bone meal is used in a water source above the aforementioned solid blocks.

Dead coral is created when coral is placed out of water.

Usage
Coral can be used as a building or decoration block.

Dead coral
In order for coral to stay alive, at least one of the blocks surrounding it must be water. If placed outside of water, it dies and transforms into its respective dead coral after a few seconds.

Dead coral cannot be turned back into living coral.

Note Blocks
All types of coral and dead coral can be placed under note blocks to produce "bass drum" sounds.
