Horn Coral Block is a vibrant, underwater block resembling the horn coral polyp found in warm ocean biomes. It emits a small amount of light and can only be harvested with a Silk Touch enchanted tool. If placed outside of water or if water next to it is removed, it will quickly transform into a dead coral block, losing its color and brightness. It serves primarily as a decorative element for building or crafting.
