ExtraBiomes
Vanilla Minecraft has plenty of biomes, but after a few hundred hours, the overworld can start to feel familiar. ExtraBiomes is a world generation add-on that tackles that problem head-on, adding 26 new biomes to the overworld along with the mobs, blocks, and structures needed to make each one feel alive. From burnt forests and jellyfish-filled oceans to a floating Sky City above the mountains, this project reshapes exploration in a way few world-gen mods manage.
What ExtraBiomes Adds to Your World
The core appeal is variety. ExtraBiomes doesn't just recolor existing terrain; it introduces entirely new biome concepts. The Frozen Mesa reimagines a mesa biome after a winter that never ended, while the Glacier stretches a solid block of ice from hilltop to bedrock, hiding ice caves where lapis spawns more often. The Grand Oasis offers palm trees, hidden treasure, and the bones of giants, and the Jellyfish Fields covers the seafloor with moss, coral structures, and sea pickles.
Other highlights include:
- The Netherlands, a surface tribute to tulip fields and windmills with a mini-Nether hidden underground
- The Mystic Forest, a fantasy swamp with glowing purple trees and fog
- The Sky City, a jigsaw structure of floating islands connected by cloud paths and defended by harpies
- The Charred Forest, a scorched basalt wasteland still smoldering from ancient heat
- Overhauled Mushroom Islands with new mushroom types and Hoppleshroom mobs
Sub-biomes extend the theme underground. Underground jungles spawn beneath jungle biomes, the lush mesa continues its terracotta palette below the surface, and the Deep Dark can even compete with an underground jungle for space.
New Mobs and Blocks
Biomes alone would feel empty without inhabitants, so ExtraBiomes fills them. The Puckoo is a rideable, tamable mob that's fast but struggles to jump. Giant tortoises patrol jungles and lush mesas, spinning into a ball to attack and dropping scutes when defeated. Piranhas spawn in large groups in jungle waters, and bait crafted from worms is your best escape. Harpies guard the Sky City and throw razor feathers, which double as a throwable weapon you can upgrade to diamond and netherite.
On the building side, expect roughly 100 new blocks and over 30 items. Three full wood sets (mystic, palm, and sky) come with planks, doors, stairs, fences, trapdoors, and boats. There are also 12 mushroom colors with matching huge mushroom variants, dense cloud bricks, pebbles, and nether ore variants.
Supported Versions and Loaders
Java Edition
The Java port is currently in beta and supports Minecraft 1.20.1 through 26.3, covering releases like 1.20.1, 1.20.4, 1.20.6, 1.21.1, 1.21.4, 1.21.5, 1.21.8, 1.21.10, 1.21.11, 26.1.2, 26.2, and 26.3. It requires architectury-api, TerraBlender, and GeckoLib as dependencies, and can also be compiled from source by cloning the repository.
Bedrock Edition
On Bedrock, all textures include PBR maps, so the add-on works with RTX resource packs and the new shader system out of the box. You'll need to enable the required Bedrock experiments before loading a world.
How to Install ExtraBiomes
Installation is straightforward on both platforms. If you want to download ExtraBiomes, grab it from the official sources listed for your edition, then follow these steps:
- Java: install Fabric or Forge, drop architectury-api, TerraBlender, and GeckoLib into your mods folder, then add the ExtraBiomes jar
- Bedrock: import the .mcaddon file, activate the behavior and resource packs, and enable the required experiments
- Start a new world so the new biomes generate correctly
If you'd rather skip manual dependency juggling, the foxygame.net launcher handles the whole setup for ExtraBiomes in a single click, pulling the correct loader and library versions automatically so you can jump straight into a new world. Compatibility has been tested against a wide grid of popular mods, though if you hit a feature cycle bug, filing a GitHub issue is the recommended path, and Feature Recycler can serve as a temporary fix.
Final Thoughts
ExtraBiomes is one of the more ambitious world generation projects available for Minecraft, and it shows in the details, from the glowing purple goo of the Mystic Forest to the razor feathers of the harpies. Whether you're building in the Netherlands, surviving piranha-infested jungles, or scaling the Sky City, there's enough new content here to make every new world feel genuinely unexplored. Just remember to enable the right experiments on Bedrock and install the Java dependencies before you start.
