Fire Coral is a vibrant underwater block resembling a plant that can be found in warm ocean biomes. It must be collected with a tool enchanted with Silk Touch; otherwise, it drops nothing. When placed on land, it quickly transforms into a dead coral block unless it's adjacent to water. It serves no specific purpose other than for decoration or to craft fire coral blocks, which are purely aesthetic as well.
