The Swamp biome is a biome which generates in a Minecraft world. The biome is mostly flat, with large bodies of water surrounding fragments of land. The bodies of water and grass both have a darker coloring than normal. The swamp contains oak trees with vines growing on them, as well as lilypads scattered throughout the water. The swamp biome is the only location where witch huts can spawn. At night, slimes can naturally spawn based on the moon phase. On a full moon, slimes spawn very often, whereas on a new moon, no slimes spawn.
