Santa’s Fuse turns the Steal a Brainrot lobby into a temporary Christmas lab. For a limited time, this machine replaces the Brainrot Trader and lets you combine four existing brainrots into one of fifteen holiday variants with boosted income and unique rarities.
Santa’s Fuse works on the same core rules as the regular Fuse Machine and Witch Fuse: feed it high‑value units, wait out a timer, and hope the roll lands on a rare outcome. The difference is that every result here is tied to the Winter Hour event, and several top‑end secrets only appear when you use particularly strong recipes.
Where Santa’s Fuse sits in the Steal a Brainrot loop
Santa’s Fuse is a time‑limited machine that takes over the spot normally occupied by the Brainrot Trader in the main lobby. You reach it as soon as you load into the hub, without needing to unlock any extra area.
The machine has the same general shell as the normal Fuse Machine, but dressed up with Christmas decorations. Functionally, it belongs in the same family as the existing fusion systems:
- Fuse Machine – the standard fusion system.
- Witch Fuse – a thematic variant with its own pool and secrets.
- Santa’s Fuse – the holiday machine, again with its own exclusive pool and secrets.
Each of these machines trades four brainrots for a single, typically stronger, output. Santa’s Fuse follows that pattern but only rolls from its seasonal Christmas list.

All Santa’s Fuse brainrots and their stats
Santa’s Fuse has 15 possible outcomes spanning Common to Secret. Some outcomes list exact income values per second, while a few high‑end units still have “TBA” tuning.
| Brainrot | Rarity | Income (per second) | Notes |
|---|---|---|---|
| Noobini Santanini | Common | $11/s | Entry‑level Christmas brainrot with basic income. |
| Frogo Elfo | Rare | $67/s (listed elsewhere as TBA) | Low‑mid tier holiday unit; high fuse odds with simple recipes. |
| Penguin Tree | Epic | $270/s | Epic‑tier option from four Cappuccino Assassino, with very high success chance. |
| Chocco Bunny | Legendary | $1.4K/s | Legendary outcome; specific recipe odds are not fully published. |
| Sealo Regalo | Legendary | $1.8K/s | Another Legendary drop with higher income than Chocco Bunny. |
| Jingle Jingle Sahur | Mythic | $12.2K/s | One of two Mythic Christmas Sahur variants. |
| Tree Tree Tree Sahur | Mythic | $17K/s | The higher‑income Mythic Sahur roll. |
| Yeti Claus | Brainrot God | $257.5K/s | Top‑tier non‑secret option, with very high earnings. |
| Ginger Globo | Brainrot God | $257.5K/s | Brainrot God income on par with Yeti Claus. |
| Ginger Cisterna | Brainrot God | $293.5K/s | The strongest Brainrot God in the Santa pool by income. |
| La Vacca Prese Presente | Secret | $600K/s | Secret‑tier unit that still sits below the highest‑earning secrets. |
| Ho Ho Ho Sahur | Secret | $3.2M/s | Secret Sahur variant with very high income. |
| Chicleteira Noelteira | Secret | $15M/s (15.5M/s in some listings) | Ultra‑rare secret; can reach around 50% odds with extremely strong inputs. |
| La Gingerbread Kepat | Secret | TBA | Income not finalised; secret‑tier rarity. |
| Cooki and Milki | Secret | $155M/s | The highest known earner in the Santa pool, with very low fuse odds. |
How Santa’s Fuse calculates outcomes
Santa’s Fuse always takes four brainrots as inputs. Those can come from three places:
- Buying from the Red Carpet.
- Stealing from other players.
- Picking up units already placed on your own base.
Once you place four units into the machine, a UI displays:
- The full list of brainrots you can roll from that specific recipe.
- The percentage chance for each outcome.
- The fusion time required.
- The cash cost to start the process.
Several patterns hold across the whole machine:
- Higher input rarity raises your floor. Better inputs push the minimum possible outcome up into higher rarities, and increase the odds on Brainrot God and Secret units.
- High‑value inputs unlock secret tiers. Secret brainrots only appear in the roll window when all four inputs meet a certain strength. If one input is weak, the secret tier can disappear entirely.
- Stronger inputs increase fuse time. High‑rarity or mutated brainrots yield better results but also require longer timers to complete the process.
- Fused brainrots cannot be fused again. Once a result walks to your base, it is treated as final; the game prevents chaining it back into Santa’s Fuse.

How to use Santa’s Fuse machine
Step 1: Go to the center of the lobby where the Brainrot Trader normally stands. Interact with Santa’s Fuse to bring up the fusion screen.
Step 2: Add four brainrots to the machine. Use the collect zone in front of the machine to submit units from your inventory, stolen units, or ones you pick off your base.
Step 3: Check the preview panel. Review the list of potential outputs, their percentages, the listed traits or mutations, the expected fusion time, and the cash cost.

Step 4: If the odds are not what you want, remove one or more inputs and replace them with stronger brainrots. Watch how the roll window updates, especially the appearance or disappearance of Secret results.
Step 5: When you are satisfied with the chances, pay the displayed cash fee to start the fusion. A timer will begin, and the machine will remain busy until it finishes.

Step 6: Wait for the fusion to complete. When the timer hits zero, the resulting Christmas brainrot exits the machine and walks toward your base, where you can place it to start earning income.
Known recipes and max‑chance fusions
The machine shows odds for every recipe directly in the UI, but a few combinations stand out for reliably producing specific tiers.
| Target brainrot | Inputs | Max chance (approx.) | Notes |
|---|---|---|---|
| Noobini Santanini | 4 × Noobini Pizzanini / 4 × noobinis | 67% | Simple entry recipe, good for padding early holiday roster. |
| Frogo Elfo | 4 × Trippi Troppi | 96% | Very reliable way to get Rare‑tier Frogo Elfo. |
| Penguin Tree | 4 × Cappuccino Assassino | 94% | High Epic odds for players with mid‑tier inventories. |
| Chicleteira Noelteira / Ho Ho Ho Sahur / Cooki and Milki | Swag Soda, Los Mobilis, Uniciclino, Mieteteira Bicicleteira | Chicleteira ~50%, Ho Ho Ho ~48%, Cooki and Milki ~2% | Example of a “high‑value” mixed recipe that unlocks three secret results. |
Chicleteira Noelteira, La Vacca Prese Presente, La Gingerbread Kepat, and Cooki and Milki sit in the top tier of the pool. These secrets never appear in the roll list when even one input is too weak, so they effectively require late‑game brainrots or strong mutations as fuel.
How secret brainrots work in Santa’s Fuse
Secret brainrots in Santa’s Fuse are not simply low‑percentage entries; they are conditional. The machine has an internal “secret tier” that only becomes available when all four inputs meet a certain minimum threshold for earnings or rarity.
- If all four inputs are strong enough, the Secret tier appears, and several Christmas secrets occupy that band.
- If even one input drops below the bar, the machine removes the Secret tier from the outcome list entirely, making it impossible to roll any secret from that recipe.
This means that for most players, secrets are less about pure luck and more about building toward specific, expensive recipes. Once your income base can comfortably produce and recycle Brainrot Gods and late‑game legendaries, the secret tier turns Santa’s Fuse into the main path for seasonal progression.

Why Santa’s Fuse matters for progression
Santa’s Fuse is not just cosmetic. Several of its outcomes, particularly the Secret and Brainrot God units, dramatically outpace the earnings of typical non‑event brainrots at the same stage of the game.
- Cooki and Milki pushes income into the hundreds of millions per second.
- Ho Ho Ho Sahur and Chicleteira Noelteira offer multi‑million income ticks with different probability profiles.
- Yeti Claus, Ginger Globo, and Ginger Cisterna give you Brainrot God‑level income without needing to hit secret odds.
Because Santa’s Fuse is limited to the Winter Hour and Santa’s Fuse update window, these units function as both short‑term power spikes for current runs and longer‑term collectibles once the machine rotates out. Investing high‑value brainrots into fusion while the machine is active is the main way to secure these seasonal earners.
Once you are comfortable feeding high‑tier brainrots into Santa’s Fuse, the machine becomes less of a novelty and more of a late‑game accelerator. Pick recipes that keep the Secret tier visible, watch the percentages on each attempt, and treat every successful Cooki and Milki or Chicleteira Noelteira as a structural upgrade to your income curve long after the Christmas decorations disappear from the lobby.
