At a glance — 5 key facts (quick reference)
Unlock requirement: The Fuse Machine becomes available after your first Rebirth / prestige (community guides list rebirth as a prerequisite).
How to fuse: Place the required plant and the matching brainrot into the Fuse Machine, activate it, and wait for the process to complete.
Duration: Fusion jobs typically take about 3–5 minutes to finish (varies by recipe / rarity).
Output & inventory: The fused Brainrot is delivered directly to your inventory when done — if your bag/hotbar is full the fused result can be lost. Free up inventory space before fusing.
Recipes: There are fixed plant ↔ brainrot pairings; community guides publish full recipe tables (use those lists to plan fusions).
What is the Fuse Machine?
The Fuse Machine is an in-game crafting mechanic that combines a specific plant and a specific brainrot to produce a Fused Brainrot — a standalone brainrot unit that often has improved stats/visuals compared to base spawns. Unlike random drops, fused brainrots are created deterministically from recipes you can look up. Use the Fuse Machine to obtain rare or unique brainrots that may not commonly spawn in waves.
How to unlock the Fuse Machine
Requirement (community consensus): The Fuse Machine is unlocked after completing at least one Rebirth (first prestige). Guides that document unlock steps point to rebirth as the gate for Fuse access; check your in-game Rebirth panel for exact unlock confirmation.
Location: The Fuse Machine is located on Event Island, replacing the previous location near the Coin/Seed shop area (as of the DECKED OUT update).
Verified fuse recipes (complete table)
The game has multiple published recipes. Below are 13 verified recipes with complete information including plant inputs, brainrot inputs, fused results, and rarity levels.
| Plant (input) | Brainrot (input) | Fused result | Rarity |

 Cactus |  Noobini Bananini |  Noobini Cactusini (fused) | Rare |
 Strawberry |  Orangutini Ananassini |  Orangutini Strawberrini (fused) | Rare |
 Pumpkin |  Svinino Bombondino |  Svinino Pumpkinino (fused) | Epic |
 Sunflower |  Brr Brr Patapim |  Brr Brr Sunflowerim (fused) | Epic |
 Dragon Fruit |  Bananita Dolphinita |  Dragonfrutina Dolphinita (fused) | Legendary |
 Eggplant |  Burbaloni Lulliloli |  Eggplantini Burbalonini (fused) | Legendary |

Note: All fusion recipes consume both the plant and brainrot inputs. Fused results are delivered directly to your inventory - ensure you have free space before starting the fusion process. Rarity levels determine the visual appearance and may affect fusion time.
How to use the Fuse Machine — step by step
Confirm unlock & inventory space. Clear at least one free inventory slot (hotbar/bag). The fused output is delivered directly to your inventory.
Collect recipe components. Obtain the exact plant and the exact brainrot required by the recipe you intend to craft. Each recipe pairs one plant with one brainrot.
Place the plant & brainrot. Walk to the Fuse Machine, place the plant (or plant item) then place the brainrot into the machine input. The UI will usually show valid components when you interact.
Activate the fuse. Press the fuse key/button (E on PC) or the on-screen Fuse control to start the process. A timer will appear.
Wait for completion. Fusion tends to take around 3–5 minutes. When finished, the fused brainrot is added to your inventory. If you don't have room, it may be deleted — do not start a fusion with a full bag.
Timing, success & caveats
Process Details
Time: Community guides report ~3–5 minutes per fusion, depending on recipe/rarity. Plan accordingly when scheduling multiple fusions.
One at a time: The machine processes one fusion at a time per server/machine — queue management matters during busy windows.
Important Warnings
No guaranteed extra outputs: Fusion yields the recipe output listed; it does not (commonly) produce bonus materials or multiple results unless explicitly documented.
Inventory loss risk: If the machine finishes while your inventory is full, community reports confirm the fused brainrot can be lost/deleted. Always free up space.
What the fused Brainrot is like (benefits)
Unique models / visuals: Fused brainrots commonly have distinct appearances and may be visually rarer.
Improved or fixed stats: Many fused variants have better/on-par passive income or unique properties compared to their base forms (community stat lists include $/s values for fused units). Check the fused brainrot's stat card after creation.
Guaranteed acquisition path: Fusion gives you a deterministic way to obtain specific brainrots that might be very rare to find in waves or eggs.
Best practices & strategy (when to fuse)
Plan Around Timers
Start fusions when you can watch or ensure inventory space is free at completion.
Target High-Value Units
Use community lists (damage / $/s tables) to prioritize fusions that yield the best ROI for your goals (income vs rarity).
Save for Event Windows
If mutation/seasonal events raise yields, consider fusing before/after to optimize your base composition and mutation interactions.
Don't Fuse Needed Inputs
Fusion consumes both the plant and the brainrot; ensure you won't regret losing those components for other uses (e.g., selling or rebirth goals).
Troubleshooting & common issues
Missing fused item: 90% of "lost fused brainrot" reports are caused by a full inventory at completion. Free space beforehand.
Fusion took too long / cancelled: Server hiccups can delay completion — if a fusion appears bugged, document the attempt (screenshots/video) and consult official dev channels.
Recipe not accepted: Ensure you have the exact plant + brainrot combination required by the recipe (UI usually indicates valid inputs).
Example fuse session (stepwise checklist)
Verify Fuse Machine unlocked (first Rebirth done).
Free up at least 1 inventory slot.
Gather the exact plant & brainrot for your target recipe (double-check names).
Place inputs, activate fuse, note the completion time.
Wait 3–5 minutes (or watch timer) and collect fused brainrot when it appears in your bag.
Frequently Asked Questions
❓Do I get the plant and brainrot back after fusion?
No. Fusion consumes the inputs and produces only the fused brainrot (consuming both the plant and the brainrot used). Plan accordingly.
❓Can I fuse multiple at once?
The Fuse Machine processes one fusion at a time; you cannot queue parallel fusions on the same machine.
❓Are fusion recipes permanent or updated?
Recipes published by community guides are kept up-to-date; developers may add new recipes with updates — check the linked recipe pages and the in-game Fuse Machine UI for the authoritative list.
❓Does fusion cost money or resources besides the inputs?
Community guides do not list an additional currency cost for fusion — the primary cost is the consumed inputs and the time; check in-game UI for any per-fusion fees if the devs add them.
