Mangrove Roots

Mangrove roots are blocks that form as part of mangrove trees. Mangrove roots, despite being a full block, can be waterlogged and do not flow water out.

Breaking
Mangrove roots can be broken by hand, but using an axe is quickest. Mangrove roots drop themselves when broken with any tool.

Natural generation
Mangrove roots are generated in mangrove swamp biomes.

Post generation
When mangrove propagules grow, they develop roots that can vary in size.

Redstone
Redstone circuits can pass their power level through mangrove roots and power other redstone components that are adjacent to the block, even when waterlogged. Waterlogged mangrove roots follow the same mechanics as any other waterlogged block.

Composting
Mangrove roots have a 30% chance of increasing the compost level in a composter by 1.

Note blocks
Mangrove roots can be placed under note blocks to produce "bass" sounds.

Smelting
When used in a furnace as fuel, mangrove roots last 15 seconds (smelting up to 1.5 items).
