Dead Horn Coral Block
Dead Horn Coral Block is the gray, lifeless variant of the vibrant yellow horn coral block, sharing its texture but lacking color. It forms either when a live horn coral block is placed outside of water (causing it to dry out after a few seconds) or naturally in coral reefs in Bedrock Edition. In Java Edition, it only appears through post-generation decay.
This block is decorative in nature and works well for building ruins, underwater decay, or aged structures. It can be mined with any pickaxe, always dropping itself regardless of enchantments or tool type. When placed beneath a note block, it produces a 'bass drum' sound, giving it a subtle use in redstone music setups.
