Steal A Brainrot Halloween Event Guide (November 2026) Haunted Fuse & More

Table Of Contents

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.

Steal A Brainrot 2026 Halloween Event Guide

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.

Haunted Fuse: All New Brainrots

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.

Plant BrosSecret$300M/s
Sammyni SpookyniSecret$80M/s
Oni Oni PandaSecret$27M/s
Fangaro LupinoSecret$7.2M/s
Los TreatersSecret$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.

Eclipse Mutation Explained

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.

Skull Lucky Block Odds

Update 70’s block costs $500M and gives one brainrot after its timer.

BrainrotChanceIncome
Candi Corni32.4%$321K/s
Grim Cheese30%$1.6M/s
Zombie Bowl21%$4.5M/s
Bananito Skelito10%$8.5M/s
Bat-in-the-Box5%$22.5M/s
Boo Boo Rocket1%$37.5M/s
Flying Dutchman0.5%$92.5M/s
Dragon Skeletonini0.1%$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.

Reaper Base

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.

What to Prioritize First?

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.

Pro Tips and Common Mistakes

  • Never fuse your main earners. Use duplicates you can afford to lose.
  • Check the preview first. Odds depend on your exact recipe.
  • Ignore 2025 content. The Spooky Lucky Block, Witch Fuse, Trick or Treat and Witching Hour were last year’s, yet several guides list them as 2026 features.
  • Skip the index hunt. I found no 2026 Halloween Index on the wiki, so don’t spend on one yet.
  • Protect Phoenix. High-value units are prime theft targets in public servers.
