The Steal a Brainrot universe just got a terrifyingly fun twist. This year’s Halloween update brings the mysterious Witch Fuse, a brand-new limited-time machine that will change how players collect, fuse, and hunt Brainrots. With over 20 new Brainrots, 4 secret fusions, and a new timed event system — this is shaping up to be the game’s biggest event yet.
The Witch Fuse is a special Halloween fusion machine replacing the regular Craft Machine. The update officially launches October 12 at 12:30 AM, with early teasers already haunting the lobby.
Players will notice a witch stirring her cauldron in the shadows — that’s the first sign of what’s coming. Expect green smoke, bubbling effects, and an all-new Halloween-themed environment during the event.
Witching Hour Event
A brand-new global event system called the Witching Hour is being introduced:
Occurs every 2 hours
Spawns 1 of 4 Halloween-themed Brainrots randomly across servers
Collect all 4 spooky Brainrots to unlock La Spooky Grande, a limited-time exclusive with only 750K stock
This creates a new cycle of hunting, collecting, and fusing — rewarding players who stay active and time their sessions strategically.
New Brainrots (Halloween Set)
Here’s the confirmed list of revealed Halloween-themed Brainrots so far:
La Spooky Grande – A pumpkin-headed evolution of La Grande, glowing with eerie vines.
Eviledon – The dark, red-horned evolution of Talaledon, featuring corrupted limbs and demonic energy.
Jacko Jack Jack – A jester-like pumpkin hybrid with stitched features and sinister charm.
Los Mobilis – A Halloween-styled animated model with pumpkin motifs and glowing symbols.
According to testing leaks, each of these Brainrots features fully animated models and distinct movement patterns built specifically for the event. Expect bubbling, floating, and pumpkin particle effects around them.
The Witch Fuse Machine
This new machine is more than just a cosmetic reskin — it’s a core gameplay mechanic overhaul for the event period.
Replaces the Craft Machine temporarily
Allows fusing of over 20 Brainrots
Introduces 4 new “fusible secrets” — rare combinations only the Witch can create
Includes unique animations: cauldron bubbles, potion mixing, and magical smoke
Players will need to gather enough Brainrot materials from Witching Hour events to perform these fusions. It’s expected that once the event ends, the Witch Fuse will disappear — making these limited Brainrots permanently exclusive.
Visual & Map Changes
Early testers have spotted several environmental updates tied to Halloween:
Lanterns and pumpkins across the map
Cauldron effects near the Witch Fuse zone
Fog and candle lighting for ambience
A new “Haunted Forest” variant used during Witching Hour spawns
Expect darker tones and glowing highlights — perfect for a spooky yet colorful Halloween feel.
Special Leaks and Hidden Details
Leakers like Sonic and Shivang revealed early footage from the test server:
The Witch model has full cinematic animations, stirring a green potion while summoning Brainrots.
Eviledon showcases upgraded red particle effects and long demonic claws.
La Spooky Grande glows orange and gold with animated vines.
New secret Brainrot models were spotted in the background, suggesting an unrevealed tower-like creature might appear later in the event.
The community believes these unseen models could be part of a Phase 2 Halloween expansion, possibly next weekend.
The Witch Fuse Update is easily one of the most ambitious events Steal a Brainrot has ever done. Between the new machine, 20+ fusions, and timed Halloween mechanics, it redefines how players engage with the game’s crafting system.
If you thought Extinct Brainrots were wild — the Witch’s cauldron is brewing something even crazier. Prepare for haunted visuals, secret recipes, and limited exclusives that might never return.
