3. Eclipse Event and Mutations: How to Get Them
The Eclipse event is a limited-time event that occurs every hour on weekends and every two hours on weekdays.
How to participate: Stand near the Haunted Fuse collect zone and wait for rare Brainrots to spawn, which you can take back to your base. During the Eclipse event, these Brainrots have a chance to receive the Eclipse mutation.
Pinch of Cash (55.75%)
Wallet of Cash (34%)
Truckload of Cash (7.5%)
2× Luck (2%)
Eclipse Secret Lucky Block (0.5%)
Eclipse Slap (0.25%)
Eclipse Hammer (TBA)
The Eclipse mutation significantly boosts income. Eclipse Phoenix generates up to $5.7B/s.
Strategy tip: Treat the Eclipse event as a limited-time mutation window. Before the event triggers, position the Brainrots you want to mutate near your base so you can act quickly when it starts.
4. Haunted Fuse Machine: Step-by-Step Guide
The Haunted Fuse is the seasonal alternative to the standard fusion system, located in the center of the map as a standalone structure.
How to Use It
Bring four Brainrots from your personal inventory to the Haunted Fuse's Collect Zone. Note: freshly stolen units are not registered as personal and will be rejected.
Deposit the units into the machine's input slots one at a time.
Check the Possible Fusions panel to see potential outcomes based on your inputs.
Review the output chances and fusion timer before committing materials.
Click the Cash button to pay the fusion fee and start the machine.
Return after the timer ends to claim your fused Brainrot.
Important: The Haunted Fuse is a personal machine—no other player can interact with it or steal your deposited characters while a fusion is in progress.
Fusion Time and Costs
Inserting Secret or OG rarity units requires an additional 1 hour 30 minute fusion timer.
The cash cost and exact timer are displayed on the machine's interface for your specific selection.
5. Spooky Lucky Block Rewards
In addition to the Haunted Fuse, the Spooky Lucky Block contains several Halloween-exclusive Secret Brainrots:
Name | Rarity | Income | Drop Chance |
Los Spooky Combinasionas | Secret | $20M/s | 1% |
Telemorte | Secret | $2M/s | 6.7% |
Pumpkini Spyderini | Secret | $650K/s | 4% |
Trickolino | Secret | $900K/s | 2.5% |
Jackorilla | Secret | $315K/s | 10% |
Los Spooky Combinasionas is the rarest, with only a 1% drop chance and a base income of $20M/s. With a Rainbow mutation, it reaches $200M/s.
6. Halloween Traits
During the Halloween event, certain seasonal traits can be applied to Brainrots while they are still out on the map:
Trait | Multiplier | How to Get |
RIP Tombstone | 4.5x | Randomly applied during Halloween event cycles |
Witching Hour | 4x | Randomly applied to Brainrots on the Red Carpet |
Important: Once a Brainrot walks into your base, it cannot pick up any more traits or mutations. During a trait event, have a friend or alt buy the Brainrot back and forth while it walks to keep it exposed to event effects.
Stacking: Traits and mutations stack. An Eclipse Phoenix with RIP Tombstone or Witching Hour will earn significantly more.
7. High-Efficiency Strategies
Strategy 1: Prioritize Phoenix, then chase mutations
Phoenix is the event's highest-income Secret. First, obtain a base Phoenix through Haunted Fuse or Lucky Blocks, then use the Eclipse event to mutate it. An Eclipse Phoenix at $5.7B/s far outperforms most other Brainrots.
Strategy 2: Concentrate activity during Eclipse events
Eclipse triggers every hour on weekends and every two hours on weekdays. Plan your playtime around these windows and keep your best Brainrots near the Red Carpet for quick mutation opportunities.
Strategy 3: Always check the fusion preview
The Haunted Fuse displays potential outputs before you commit materials. Never invest rare Brainrots blindly—check the preview first and confirm there's a target worth pursuing.
Strategy 4: Protect your high-value Brainrots
Top-tier Brainrots like Phoenix and Eclipse Phoenix are prime theft targets. Transfer them to a secure alternate account for safekeeping during public server play.
Strategy 5: Don't fuse your main earners
Use replaceable duplicates or units you can afford to lose. A failed fusion roll is much easier to absorb when it doesn't remove your primary income source.
