Mangrove Roots are blocks that form as part of mangrove trees in the mangrove swamp biome. Despite being a full block, they can be waterlogged without affecting the surrounding environment.
They can be broken by hand, but using an axe is the fastest method. Mangrove roots drop themselves when broken with any tool. These roots are useful in redstone circuits, as they can pass redstone power even when waterlogged. Mangrove roots can also be used in crafting to create Muddy Mangrove Roots and are a 30% chance composting ingredient. When placed under a note block, they produce a 'bass' sound.
