Added in 1.19, the mangrove swamp is a lush, waterlogged biome of tangled mangrove roots, hanging propagules, and murky water. It's the exclusive home of frogs, tadpoles, and froglights, plus the mud and mangrove wood that make it a favorite for organic builders.
📐 See our Methodology page for the complete verification process.
Mangrove swamps are uncommon and generate only in warm regions, so having one near spawn saves a long trek. These verified 1.21 seeds place a mangrove swamp within easy reach of your starting point.
Why the Mangrove Swamp Is Special
- Frogs live only here (and regular swamps) — feed them magma cubes for coveted froglights
- Mangrove wood is a unique reddish log; strip roots for a distinctive build palette
- Mud blocks convert to clay/packed mud/mud bricks — a full building material chain
- Tadpoles grow into frogs whose color depends on the biome temperature they mature in
- Mangrove propagules can be grown into new trees anywhere, even underwater
- Dense roots and water make it slow to traverse — boats and a good path help

❓ FAQ
Q: What version added mangrove swamps?
Mangrove swamps were added in Minecraft 1.19 (The Wild Update) along with frogs, tadpoles, mud, and mangrove wood. These seeds are verified for Java Edition 1.21.
Q: How do I get froglights?
Froglights drop when a frog eats a small magma cube. The frog's color (and thus the froglight color) is determined by the temperature of the biome where the tadpole matured — so breed tadpoles in different biomes for all three colors.
Q: What's the difference between a swamp and a mangrove swamp?
Regular swamps have oak trees, lily pads, and slimes; mangrove swamps have mangrove trees, roots, mud, and warmer coloring. Both spawn frogs. Mangrove swamps are the only source of mangrove wood and mud.
Q: Do these seeds work in Bedrock Edition?
They were verified on Java Edition 1.21. Bedrock generates worlds differently, so the exact coordinates won't match — use these on Java for the listed locations.
