ExtraBiomes

ExtraBiomes is a world generation addon for Minecraft Bedrock that adds 24 new biomes to the overworld, along with the mobs, blocks, and structures to fill them — from burnt forests and jellyfish-filled oceans to a floating Sky City above the mountains. All textures include PBR maps, so the addon works with RTX resource packs and the new shader system out of the box.

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 biome 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 which is 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 corral 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 a lot of 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 there is 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 similar to that of a It once had generation similar to that of the shattered savanna biome, however now has stone and tuff pillars towering through, there are patches of moss on the ground and bamboo throughout, and the 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, in my opinion, this is a massive upgrade to the vanilla ice spikes biome, giving it so much more life than the vanilla ice spikes.
This biomes is the Ice Spikes biome but with Tiaga 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 which are a custom tree type that can be found here and they are 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 like the underground jungle, and like the underground mesa, the underground lush mesa 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) in the concept art you see below. 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, so be careful when in the Jungles. The giant tortoise attacks by spinning a ball towards you and charging into you, using its sharp shell to do damage to the player. This mob can also jump up to 10 blocks in the air in a spinning mode. These mobs are also great swimmers and drop scutes when killed.
|
Jellyfish
Jellyfish are a mob that will spawn jellyfish fields and, less commonly, warm oceans and come in 2 colours, pink and purple. Getting near it can cause it to sting you, and you can catch it in a jellyfish net, or click it with a glass bottle to give you a jar of jellyfish jam.
|
Treefrogs
Treefrogs can be found in jungle biomes and their variants, as well as in swamps/ mangrove swamps, these mobs are different to normal frogs, they can jump higher, and also they drop frog's legs when killed which either can be cooked or be used to make a frog hat which can be worn by both you and your dog.
|
Worm

The worm mob can be found throughout the overworld, but most commonly in the rain or thunderstorms, and can be used to craft bait which is a throwable item that can be used to lure the piranha mob away from you so you don't get eaten when crossing the waters inside jungle biomes, lush mesa biomes and the underground jungle biomes too.
|
The Harpy
The harpy mob can be found in the sky city, either by spawning in or from the spawners that can be found inside of the towers in the sky city, the harpy is a flying mob and will attack you by throwing a volley of razor feathers at you. razor feathers are a throwing knife-like weapon, which deals a moderate amount of damage when they hit you. On death the harpies will drop razor feathers which are thrown on use like a snowball and will spin through the air, however, they can be picked up where they land and also can be upgraded to a diamond and netherite version.
|
Piranhas
the piranha is a dangerous hostile mob that spawns throughout the different jungle biomes that can be found in extrabiomes as well as rarely in mangrove swamps, an individual piranha will barely hurt you, however, these mobs will spawn in very large groups, and that can lead to you being eaten up very quickly if you fall into piranha-infested waters, try to avoid falling in, and if you do fall into piranha-infested waters, make sure you have some bait with you, bait can be crafted from worms, and once thrown, piranhas will prefer to eat it over eating you, and so you will be able to swim to safety.
|
Hoppleshroom
Hoppleshrooms are mobs that can be found around the mushroom island, fungal jungle, underground mushroom island and a warped and crimson forests. the hoppleshrooms are little mushrooms that come in 12 different colours, they will hop around the mushroom/fungus biomes making a squeaky sound and spreading a dusting of spores behind them, these spores then have a chance to grow a mushroom. the hoppleshrooms also have baby versions and can be breed by feeding hoppleshrooms any mushroom, however, they refuse to pathfind towards a mate so you may need to give them a nudge into another one.
|
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.
