LEGO Fortnite mixes survival gameplay with the charm of LEGO building. In this world, you gather resources, fight off enemies, and build your dream villages. One of the important materials you’ll come across later in the game is biomass. But many players don’t know what it is, where to find it, or how to use it.
If you’re one of those players, don’t worry this guide is for you.
We’ll go cover everything you need to know about biomass in LEGO Fortnite in simple terms. By the end, you’ll know:
What biomass is
Why you need biomass
How to unlock the tools required to collect it
Where to find biomass
How to use biomass for crafting
Tips and tricks for gathering it faster
Let’s jump in.
what is biomass in lEGO fortnite?
Biomass is a green, plant-like crafting material used in more advanced crafting recipes. It looks like a clump of glowing green goods. You’ll need biomass for several important upgrades and recipes, especially when you start crafting high-tier gear or unlocking tougher areas like caves and deserts.
It’s not something you can get at the very beginning of the game. You’ll need to progress through the survival mode until you can safely explore dangerous areas and unlock the right tools.
why do you need biomass?
Biomass becomes important once you’re deep into the survival progression of LEGO Fortnite. It’s used in crafting materials like:
Essence of Nature: A key item used to make rare upgrades.
Advanced Crafting Stations: Some upgraded workbenches and machinery require biomass.
Tougher Gear : To survive tougher biomes, you need armor and tools that may require biomass as part of their crafting recipe.
Basically, biomass is your ticket to endgame items.
When Can You Start Collecting Biomass?
To collect biomass, you need to be ready for Caves and Toxic Biomes. These areas are harder to explore because they have enemies and poisonous gas. You’ll need a few things ready before you head there:
1. Upgraded Gear : Make sure you have at least rare or epic weapons and armor.
2. Gas Mask : This is essential to survive the toxic gas in the areas where biomass grows.
3. Gloves or Pickaxe : You’ll need the right tool to harvest the biomass from green glowing plants (called Sludge Plants).

Where to find biomass?
Let’s walk through the exact steps you need to get biomass in LEGO Fortnite.
Step 1: Progress Through Survival Mode
First, play through the game normally. Gather basic materials like:
- Wood
- Granite
- Knotroot
- Marble
Build your village, expand your inventory, and unlock workbenches and crafting stations.
As you progress, you’ll unlock new recipes and tools. Biomass doesn’t appear until later in the game, so just focus on early survival for now.
Step 2: Unlock and Craft a Gas Mask
Biomass is usually found in toxic areas like caves with poisonous gas. If you enter without protection, you’ll take constant damage and die quickly.
You need a Gas Mask before you try exploring these places.
- To craft a Gas Mask, you need:
- Sand Shells (from Sand Rollers)
- Cursed Bones (from cave skeletons)
- Wool Fabric
- Charcoal
Once you have the ingredients, go to a crafting station and make your Gas Mask. Equip it before entering any toxic area.
Step 3: Find a Toxic Cave or Biomass
Biomass is found in toxic caves or swampy biomass. These are areas with green fog, glowing mushrooms, and hostile creatures.
Here’s how to find one:
- Explore your map thoroughly.
- Look for Caves marked on your map, especially ones in forest or jungle biomes.
- Look for areas with green glowing mist and alien-like plants these are signs you’re close.
Tip: Bring a torch or lantern. Caves are dark, and you’ll need to see where you’re going.
Step 4: Look for Sludge Plants
Once you’re inside a toxic cave or biome with your Gas Mask on, look around for Sludge Plants. These are the glowing green plants that ooze slime they stand out in the darkness.
These plants are what give you biomass.
You can’t just punch them, though. You need the right tool.
Step 5: Use the Correct Tool to Harvest Biomass
- To harvest biomass from a sludge plant, you’ll need one of the following:
- Upgraded Pickaxe (Rare or better)
- Harvesting Gloves (optional but useful)
Approach the sludge plant and press the interaction button to harvest it. The plant will drop 1–3 units of biomass each time.
Make sure you’re careful enemies may attack while you’re harvesting.
Step 6: Store Biomass Safely
Once you’ve gathered biomass, return to your base or a nearby outpost and store it in a chest. You don’t want to lose it if you die in a fight.
You can now use biomass to craft more advanced items.
Where to Use Biomass?
Once you’ve got biomass, here’s where it becomes useful:
1. Crafting Essence of Nature
This item is needed for magical tools, potions, and higher-level upgrades.
2. Upgrading Workbenches
Some crafting stations need biomass to upgrade to their highest level.
3. Making Gas Mask Repairs
Gas Masks don’t last forever. You’ll need biomass and other materials to repair or make new ones.
How to Get Biomass Faster (Tips & Tricks)
Here are some ways to speed up your biomass farming:
1. Bring a Team (Multiplayer Help)
If you play with friends, split roles: one player clears enemies while the other harvests.
2. Use Charms or Boosts
Some charms increase your harvesting speed or reduce toxic damage.
3. Clear Out Caves Regularly
Biomass plants respawn over time, so mark cave locations and return after a few in-game days.
4. Build a Safe Outpost Nearby
Place beds, chests, and crafting stations near toxic caves to make return trips easier.
5. Keep Spare Gas Masks
If your Gas Mask breaks while inside a cave, you could die fast. Always bring a backup.
Common Mistakes to Avoid
Going without a Gas Mask You’ll die fast.
Ignoring Enemies Sludge caves have dangerous creatures like toxic slimes and cave skeletons.
Forgetting Light Sources Caves are pitch black. You need torches or lanterns.
Harvesting with Wrong Tool You’ll get nothing if you try to harvest sludge plants bare-handed.
Fun Fact: You Can Build with Biomass Too!
While it’s mostly for crafting, you can also use biomass in creative mode for green, gooey decorations. It’s great for making alien-like bases or spooky forests.
Conclusion
Biomass in LEGO Fortnite is one of the more advanced materials, but once you understand where to find it and how to harvest it, it becomes much easier to gather.
Let’s review the main steps:
1. Progress through the game until you unlock caves and toxic biomes.
2. Craft a Gas Mask to survive the toxic gas.
3. Find a toxic cave or biome and locate Sludge Plants.
4. Use a pickaxe to harvest biomass from the plants.
5. Store it and use it in advanced crafting recipes.
By following this guide, you’ll be farming biomass like a pro and building powerful gear for whatever LEGO Fortnite throws at you.
Happy gaming ^_^
