Mangrove Roots

Mangrove roots are blocks that form as part of mangrove trees. Despite being a full block, they can be waterlogged.

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.

Usage
Mangrove roots can be waterlogged, despite being a full block. Water does not spread out and waterlogged mangrove roots follow the same mechanics as any other waterlogged block.

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.

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.

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