Highlight every Mangrove Swamp on your Minecraft seed — Java 26.2 & Bedrock 1.26.30, any seed, free, no sign-up.
Quick answer: Mangrove Swamps are warm wetlands of mangrove trees, mud and roots where frogs, tadpoles and slimes thrive. This finder highlights every Mangrove Swamp on your seed, free, Java & Bedrock.
Mangrove Swamps generate on the Overworld surface in warm climates, usually next to deserts, jungles, savannas and badlands. They are dense, waterlogged tangles of mangrove trees on stilted roots, with mud underfoot and tropical fish in the water.
Enter your seed and the map highlights every Mangrove Swamp — click any highlighted patch to read its coordinates. Head there to gather mangrove propagules and mud — and to catch frogs, which you can breed into different froglight colours by climate.
They are the only place to gather mangrove wood and roots, mud (which crafts into mud bricks and packed mud), and to find frogs and tadpoles. Frogs eating tiny slimes or magma cubes drop froglights, and slimes spawn here on the surface at night.
Yes — both editions, Minecraft 26.2 on Java and 1.26.30 on Bedrock. Mangrove Swamps were added in 1.19 (The Wild Update) on both. The map highlights every patch on your seed, free and with no sign-up.
