Overworld Surface Biomes

Ever wondered what would happen to a mesa biome over the winter? well, this is it, the frozen mesa, and it is just that, in most ways, it is very similar to the regular mesa, just in a cooler climate, and also the underground mesa generates here.
These frozen mountain biomes were once mesa plateau's but as glacial erosion wore them down they became stunning peaks.
Also like the frozen mesa plateau, this is a variant of the frozen mesa, but instead of being a big flat hill, this is essentially the regular frozen mesa, but with the Bryce pillars.
A desert biome with towering Bryce pillars.
The jungle marsh is a swamp-like biome found inside jungles. Mushrooms and swamp trees will spawn here, as well as tiny jungle trees in shallow areas, tree stumps below the water level and lots of piranhas spawn here, so watch out in the water!
This biome is a jungle with gigantic pillars of stone shooting up through the skyline.
When a mesa becomes humid enough to support a jungle biome, a jungle can start to spread over the mesa to form a lush mesa. In this biome, there is a lower section where a jungle spawns; however at higher levels, it is still too dry for a jungle to spread.
The lush mesa Bryce is one of my favourite biomes so far in Extrabiomes. It is very similar to the regular lush mesa, however this has the Bryce pillars from mesa Bryce biomes, as well as lots of little lakes throughout the biome, which look really nice!
The floating jungle is a jungle biome that can be found at the tallest peaks of the world.
The fungal jungle emerges when a jungle meets a Mushroom Island, with patches of mycelium spread across the ground letting hoppleshrooms and mushrooms live here, and the dense jungle around their clearings contains large numbers of new mushrooms.
The futuristic desert is a very rare custom desert biome with white concrete being used as sand with little futuristic trees. This biome was the first biome added before I was even planning to make it into what ExtraBiomes is today.
The glacier is an extremely deep block of ice stretching from the top of the glacier (the height of your average hill) all the way down to bedrock, with the lower layers containing Ice Caves where Lapis has a higher chance of spawning.
The Grand Oasis is a desert variant, with streaks of red sand running through, lots of palm trees, hidden treasure, and the bones of giants.
The Jellyfish Fields is a reference to the jellyfish fields in the cartoon SpongeBob. The jellyfish mob spawns here, the floor is covered with moss and there are custom coral structures and sea pickles covering the floor.
The moorlands biome is a hilly lowlands biome, covered in long grass and podzol, with lots of lakes dotted around the land. Lots of animals will spawn here as it is a perfect environment for wildlife.
The Mystic Forest is a fantasy-style swamp biome, with a mystic tree which spawns there which is a custom wood type with a purple hue, and the leaves glow. There is also a purple fog in the biome and a glowing purple goo on the floor.
The vanilla Mushroom Island has been overhauled with a load of new mushroom types.
The shattered swamp is a variant of the swamp, with terrain generation that now includes stone and tuff pillars towering through, patches of moss on the ground, bamboo throughout, and new mushrooms.
The taiga spikes biome is a variation of the ice spikes biome that contains everything you would find in a snowy taiga biome; it gives much more life than the vanilla ice spikes biome.
This biome is the Ice Spikes biome but with taiga trees, taller pillars and tuff and stone pillars.
The Netherlands is based on the real-life Netherlands on the surface: full of tulip fields, windmills and wheat fields, but underground is a mini nether in the overworld.
Like the Netherlands but with wheat fields instead of tulips.
The Charred Forest is a biome found in warm climates where it was so hot that all of the vegetation was burnt to a smouldering pile of basalt. Very little has survived here, and there are still remnants of fire and smoke throughout the biome.
The tropical island biomes can be found in warm oceans. They are sandy islands covered with grass and vegetation like moss carpets and melons, as well as palm trees (a custom tree type) and surrounded by coral.

Overworld Subterra Biomes

This is a sub-biome to the deep dark, where the deep dark is competing with the underground jungle.
The caves underneath the mushroom island have had an overhaul.
Jungle caves with giant mushrooms and Hoppleshrooms.
Ice caves beneath a glacier.
The Underground jungle and its variants are inspired by the underground jungles from Terraria and spawn under all types of jungle biomes.
The underground lush mesa generates below lush mesa biomes; it is similar to the underground jungle and is made from terracotta instead of stone.
The caves underneath the mesa now continue the terracotta downwards.

Overworld Aerospace Biomes

Sky City

High above the mountains, the Sky City generates as a jigsaw structure: floating islands connected by cloud paths, with houses, towers, and fountains built from sky wood and with dense cloud brick that you float onto — and harpies defending it.

Mobs

The Puckoo The Puckoo is a mob whose concept was submitted to me by a friend of mine (who wishes not to be named). They can also be tamed, saddled and ridden like a horse. They are fast but have a hard time jumping.	Giant tortoise The giant tortoise is a mob that can be found in Jungle biomes, underground jungles, and lush mesas. This is a very tough mob to encounter, especially in the early game. The giant tortoise attacks by spinning a ball towards you and charging into you, using its sharp shell to do damage. It can jump up to 10 blocks in the air in a spinning mode, is a great swimmer, and drops scutes when killed.
Jellyfish Jellyfish spawn in jellyfish fields and, less commonly, warm oceans. They come in two colours (pink and purple). Getting near one can cause it to sting you; you can catch it in a jellyfish net or click it with a glass bottle to get a jar of jellyfish jam.	Treefrogs Treefrogs can be found in jungle biomes and their variants, and in swamps/mangrove swamps. They jump higher than normal frogs and drop frog's legs when killed, which can be cooked or used to make a frog hat which can be worn by players and dogs.
Worm The worm mob can be found throughout the overworld, but most commonly in rain or thunderstorms. It can be used to craft bait, a throwable item that lures piranhas away so you can cross waters safely in jungle biomes, lush mesas and the underground jungle.	The Harpy The harpy mob can be found in the Sky City, either by spawning in or from spawners inside the towers. The harpy is a flying mob that attacks by throwing volleys of razor feathers. Razor feathers are a throwing-knife-like weapon which deals moderate damage; on death harpies drop razor feathers which can be picked up and upgraded to diamond and netherite versions.
Piranhas The piranha is a dangerous hostile mob that spawns throughout jungle biomes included in Extrabiomes and rarely in mangrove swamps. They spawn in large groups; bait crafted from worms will attract them so you can swim to safety.	Hoppleshroom Hoppleshrooms are little mushrooms that come in 12 different colours. They spawn around mushroom islands, fungal jungles, underground mushroom islands and warped/crimson forests. They hop around, spread spores that can grow mushrooms, have baby versions and can be bred by feeding any mushroom.

Blocks

Around 100 new blocks and 30+ items, including three full wood sets (mystic, palm, and sky — each with planks, doors, stairs, fences, trapdoors, and boats), 12 colors of mushrooms with matching huge mushroom variants, dense cloud bricks, pebbles, and nether ore variants.

Updated on August 15, 2026

Biomes: Volcanic Moss Tundra
- A cold, volcanic take on the tundra — dark, volcanic terrain (black sand and black sandstone) rather than snow, with patches of moss and moss carpet blanketing the higher ground.
- Inspired by parts of Iceland: despite the volcanic theme it keeps tundra-like cold-biome behavior (cold-variant farm animals and frogs spawn here); snowfall itself is disabled.
- Terrain shaped by volcanic features — boulders, rock formations, basalt pillars, scattered volcanoes, and a winding river of lava bordered by magma banks with basalt clusters along its edges.
- Moss grows on higher parts of the biome; lower sections are almost desert-like.
- Generates as a rare replacement for ice plains in the Overworld.
Blocks
- Added black sand and a full black sandstone block set, including chiseled, cut and smooth variants, plus slabs, stairs and walls and stonecutter/recipe support.
- Added a recipe to turn black sand into glass and recipes to craft TNT from black sand.
- Fixed the collision boxes and texture UVs on stairs across all types.
Entities
- Puckoos now have a full set of ambient and cry sounds, created from distorted peacock recordings.
