Swamp Hills

The swamp hills or swampland mutated biome is a rare variant of the swamp that no longer generates since Caves & Cliffs: Part II, and was removed in Java Edition.

The swamp hills featured hillier terrain rising up between the flat marshes. These hills would tower over the otherwise low-elevation swamp, with some large areas at high elevation without any water. Additionally, flooded areas in swamp hills tended to reach lower depths than the rest of the swamp, sometimes deep enough to have a gravel floor in place of a dirt floor, like normal oceans. Swamp huts‌[Bedrock Edition only] and fossils generated, and slimes spawned more frequently. Additionally, seagrass did not generate in flooded areas of swamp hills. If it connected to a jungle it had a chance to create a modified jungle edge biome.

The swamp hills had the same vegetation as the regular swamp, with swamp oaks, lily pads, blue orchids, mushrooms, and huge mushrooms.‌[Bedrock Edition only]
