River
Overworld (water)
A calm waterway that cuts through almost any land biome and usually leads to the ocean. Rivers are natural highways for boats, a reliable source of fish and clay, and often mark the border between two biomes.

Resources
- Clay patches on the riverbed (for bricks and terracotta)
- Salmon and squid - easy early food and ink
- Sand and gravel banks
- Sugar cane and firefly bushes along the shores
Mobs
- Salmon, squid and glow squid
- Drowned underwater (some carry tridents)
- Passive mobs wander in from neighboring biomes
Structures
- No structures of its own
Why go
- Fast, safe boat travel between regions without building roads
- Clay for brick builds without mining badlands
- Fishing spots with open-water loot tables
- Drowned hunting for copper and, rarely, tridents
Tips
- Follow a river downstream to reach the coast, where shipwrecks and ocean ruins generate.
- Rivers in frozen zones become frozen rivers - the surface turns to ice; Frost Walker boots help.
