Four collected Brainrots go into the Haunted Fuse, and the machine gives you one random result from its possible pool. Before you press Cash, check the listed outcomes, displayed cost, and timer because the exact selection and values can change.
Update 69's ECLIPSE + HAUNTED FUSE event is scheduled from October 3, 2026, at 3 p.m. ET through October 7, 2026, at 12 p.m. ET. If you are reading after that window, check the machine in-game or the Steal a Brainrot event page before planning around it.
What is the Haunted Fuse in Steal a Brainrot?
The Haunted Fuse is a Halloween-themed fusion machine added with Update 69. It sits in the middle of the map, and its green Collect Zone is where you deposit Brainrots from your own collection. The machine is tied to the event, so it may not remain available after the event window.
You cannot take a Brainrot you are currently stealing straight to the machine. Finish the steal and add the unit to your collection first. If you want to identify other machines around the map, use the Steal a Brainrot machines guide.
How to use the Haunted Fuse in Steal a Brainrot
The current Haunted Fuse setup uses four Brainrots. If a hotfix changes the interface, follow the number of visible input slots in your machine.
- Take a Brainrot from your base. Use a unit that is already part of your collection. A Brainrot in the middle of a steal cannot be deposited.
- Carry it to the Collect Zone. Go to the Haunted Fuse in the middle of the map and place the Brainrot on the green Collect Zone pad.
- Add four Brainrots. Submit the units one at a time until the machine fills its four input slots.
- Read Possible Fusions. Review the result names and any odds shown for that combination. This is your chance to decide whether the displayed pool is worth the inputs.
- Press
Cashto start the fusion. Check the full set before pressingCash, because that is when you commit the selected inventory. The machine shows the cost, so do not rely on a fixed price. Pay that displayed amount only after you are satisfied with the Possible Fusions list. - Wait for the displayed timer. The duration depends on the selection. Some Secret or OG inputs have been reported with a 1 hour 30 minute timer, but use the timer shown by your own machine.
- Return and claim the result. When the timer finishes, go back to the same Haunted Fuse, interact with it, and claim the fused Brainrot into your collection.
How do Haunted Fuse odds and Fuse Luck work?
Haunted Fuse results are RNG-based. Higher-rarity inputs are reported to improve the chance of higher-rarity outcomes, while Secret inputs are reported to push the possible pool toward Secret results. Neither choice guarantees a specific Brainrot, Phoenix, Plant Bros, or even a result with higher income than what you put in.
Fuse Luck is a reported 499 Robux gamepass that improves rare-result odds for 15 minutes. You can purchase it again for another use, and it can also be activated during Admin Abuse. No exact multiplier or guarantee is given, so treat it as an odds increase rather than a promise. If you are planning around that window, the Steal a Brainrot ADMIN ABUSE guide explains the related event context.
The Possible Fusions panel still matters more than a rarity label. A Secret result can have a lower base income than one of your sacrificed Brainrots, so compare the shown choices with what you are giving up before you pay.

| Pinealotto Fruttarino | Rare | $75/s |
| Mummio Rappitto | Epic | $325/s |

Phoenix and Plant Bros are the reported top earners in this list, but Phoenix's Haunted Fuse availability is not settled. Penguino Pumpkino also appears in some Halloween reward lists at $235/s, but its status as a Haunted Fuse output is not settled. Check the live preview rather than treating this table as a complete or permanent list.
What to check before pressing Cash
- Are the four inputs replaceable? Use Brainrots you can afford to lose. A high rarity does not make the result certain, and the outcome may earn less than one of your inputs.
- Does the preview show a worthwhile result? Compare the listed Brainrots with the income and rarity of what you are sacrificing.
- What cost and timer does the machine show? These values belong to the current selection. Make sure you have the displayed cash and can wait for the displayed duration before starting.
- Are you using a Haunted Fuse preview? Do not copy a Witch Fuse recipe and assume it works here. The Haunted Fuse's own four slots and Possible Fusions panel should guide the attempt.
Once the result is ready, return to the machine and claim it. If the event is still active, check the machine's preview before every attempt because the reward pool, cost, odds, and timer are live values.
