Steal A Brainrot’s 2026 Halloween event arrives in two updates. Update 69 added the Haunted Fuse and the Eclipse mutation, and Update 70 added the Skull Lucky Block. Together they bring 19 new brainrots, topped by Phoenix at $425M/s. I cross-checked wiki-based guides and flagged anything that conflicts, so you spend your cash wisely.
| Feature | Details |
|---|---|
| Haunted Fuse | Update 69, October 3 |
| Eclipse mutation | 14x income |
| Skull Lucky Block | Update 70, October 10, $500M |
| New brainrots | 19 |
| Best brainrot | Phoenix, $425M/s |
The Haunted Fuse replaced the Craft Machine on October 3, 2026. No end date is confirmed. One guide claims a five-week run, which points to early November, so I’d use it sooner rather than later.
Drop your brainrots into the machine, check the Possible Fusions panel for odds, pay the fee, and return when the timer ends. One guide reports freshly stolen units get rejected and Secret inputs add a 1 hour 30 minute timer.
| Brainrot | Rarity | Income |
|---|---|---|
| Phoenix | Secret | $425M/s |
| Plant Bros | Secret | $300M/s |
| Sammyni Spookyni | Secret | $80M/s |
| Oni Oni Panda | Secret | $27M/s |
| Fangaro Lupino | Secret | $7.2M/s |
| Los Treaters | Secret | $1.2M/s |
Five cheaper units fill out the machine: Mortaruga ($324K/s), Mummelo Bandello ($285K/s), Vampi Ribbitini ($185K/s), Frostino Vampiro ($17.5K/s) and Penguino Pumpkino ($235/s). Six 2025 returnees also appear (Tartaragno, Pinealotto Fruttarino, Mummio Rappitto, Quackula, Buho de Fuego, Magi Ribbitini), though they earn very little and mostly suit collectors.
The wiki lists a best-case 50% for Plant Bros using Orchidox plus Venuspino. It shows no odds for Phoenix, so I wouldn’t plan around it.
The wiki lists Eclipse at 14x, the strongest mutation in the game. One wiki page says 13.5x, so confirm in-game. The event triggers every hour on weekends and every two hours on weekdays. At 14x, Phoenix reaches roughly $5.95B/s.
The wiki still marks most Eclipse wheel rewards as unannounced. One guide lists cash prizes, 2x Luck and an Eclipse Slap at 0.25%, but I’d treat those odds as unverified.
Update 70’s block costs $500M and gives one brainrot after its timer.
| Brainrot | Chance | Income |
|---|---|---|
| Candi Corni | 32.4% | $321K/s |
| Grim Cheese | 30% | $1.6M/s |
| Zombie Bowl | 21% | $4.5M/s |
| Bananito Skelito | 10% | $8.5M/s |
| Bat-in-the-Box | 5% | $22.5M/s |
| Boo Boo Rocket | 1% | $37.5M/s |
| Flying Dutchman | 0.5% | $92.5M/s |
| Dragon Skeletonini | 0.1% | $325M/s |
About 83% of opens land on the first three rows. Your chance of hitting either top prize is just 0.6%, so treat it like a lottery ticket.
The Reaper Base costs 999 Robux and includes two free Premium Skull Lucky Blocks. Update 70’s notes call the new base “Skeleton base.” They appear to be the same item, but confirm in the shop before buying.
If cash is tight, I’d start with Oni Oni Panda. The wiki’s base-value math puts its payback at roughly 1 minute 44 seconds, the fastest among the cheaper Secrets. Los Treaters lists a best-case 91% when you feed the fuse low-tier Secrets, which makes it the safest Secret target.
For the highest income, chase Phoenix or Plant Bros, but only with inputs you can afford to lose. Open Skull Lucky Blocks as soon as their timers finish, and keep common drops like Candi Corni for collections or trades.
Update 69 launched October 3, 2026, and Update 70 followed on October 10.
Phoenix leads at $425M/s, with Plant Bros second at $300M/s. Dragon Skeletonini is the best Skull Lucky Block drop at $325M/s.
No. The Haunted Fuse is the 2026 version, and the Witch Fuse belonged to 2025.
No official end date is confirmed. Check the game’s Discord before spending big.
