All New Halloween Brainrots in Steal a Brainrot (Witch Fuse Brainrots)

by

The Halloween 2025 event in Steal a Brainrot has brought one of the most exciting features yet, the Witch Fuse.

This spooky cauldron allows players to combine multiple Brainrots to create powerful, limited-time fusions, each with unique designs, traits, and income stats.

If you’ve been wondering which Brainrots can be obtained through this system or how it works, here’s the complete guide covering all Witch Fuse Brainrots, their stats, and how to use the feature effectively.

What Is the Witch Fuse in Steal a Brainrot?

The Witch Fuse is a special event feature introduced during the Halloween 2025 update. It replaces the traditional Fuse Machine with a witch’s cauldron, allowing players to mix any four Brainrots to form new ones.

Unlike the regular fusing system, this one adds a unique twist, the mutations and traits from your submitted Brainrots can carry over to your newly fused unit, making every result slightly different.

Players can use the Witch Fuse to unlock powerful Secret, Mythic, and even Brainrot God-tier units. The process, however, isn’t guaranteed, each fusion attempt consumes the four Brainrots you offer, so preparation is key.

How to Use the Witch Fuse in Steal a Brainrot

Using the Witch Fuse is simple once you know where to look. Here’s a step-by-step walkthrough:

  1. Grab a Brainrot from your base by holding the E key.

  2. Walk over to the Witch NPC, located near the cauldron in the event area.

  3. Drop your Brainrots one by one into the Collect Zone until you’ve submitted four.

  4. Open the Witch Fuse interface and click on “Fuse” to begin.

  5. Wait for the timer to complete. The rarer the Brainrots you used, the longer the fusion time.

  6. Once complete, your new fusion will appear in your base, possibly with carried-over mutations or traits.

Pro Tip: The Witch Fuse has a chance to give higher-rarity Brainrots based on the rarity of those you fuse.

Using high-value or event Brainrots increases your odds of getting limited Secret or Brainrot God fusions.

Mutations and Traits Explained

Every time you use the Witch Fuse, the resulting Brainrot can inherit Mutations and Traits from the ones you sacrifice.

  • Mutations are stat modifiers, like Candy or Shadow, which slightly alter your Brainrot’s appearance or income rate.

  • Traits are rare aesthetic or performance bonuses, like Sombrero, Shiny, or Golden Aura, that make your unit stand out.

Each mutation or trait has a percentage chance of being transferred. For example, the Witch Fuse screen might show a 15% mutation rate and 5% trait rate, meaning only some fusions will successfully carry these extras.

The Witching Hour Event (Bonus Halloween Activity)

Alongside the Witch Fuse, the Witching Hour event lets players earn the exclusive La Spooky Grande, one of the rarest limited units in the game.

To craft La Spooky Grande, you’ll need to collect these four Halloween Brainrots from the conveyor belt during the event:

Once you have all four, interact with the Witching Hour NPC and click Spawn to summon La Spooky Grande.

Be quick — only a limited number of copies exist, and the event runs on a two-hour cooldown cycle.

Why Players Love the Witch Fuse

The Witch Fuse adds a whole new layer of strategy to Steal a Brainrot.

Instead of relying only on random conveyor spawns, players can now experiment with combinations, trade duplicates, and attempt to craft ultra-rare fusions.

Here’s why it’s become a fan favorite:

  • It rewards experimentation, each fusion feels unique.

  • Mutations and traits give customization value.

  • It provides a path to Secret and God-tier Brainrots without relying on luck alone.

  • It’s tied to limited events, keeping it exclusive and collectible.

Final Thoughts

The Witch Fuse has completely transformed the Steal a Brainrot Halloween update.

From Eviledon’s monstrous $30M/s income to the rare Spooky and Pumpky duo, this feature has introduced some of the most creative and profitable Brainrots in the game.

If you want to make the most of this event:

  • Stock up on extra Brainrots before fusing.

  • Keep experimenting with different combinations.

  • Watch for the Witching Hour timer so you never miss a spawn.

With limited availability and huge earning potential, the Witch Fuse update is easily one of the best additions to Steal a Brainrot yet.
