Minecraft wiki entry for Best_biomes_for_homes, associated text: The swamp biome offers flat space (although much of it is flooded), plenty of trees, water, and clay. Swamp huts only generate here, and slimes will spawn aboveground. Mushrooms and huge mushrooms‌[Bedrock Edition only] are fairly common, making mushroom stew a good early-game food. Lily pads are common on the water. Fossils spawn 15-24 blocks underground. Blue orchids are exclusive to swamps.
