Steal A Brainrot added a new limited-time event that completely changes how the game plays, and the Cursed Mutation is one such addition. This mutation is tied exclusively to a seasonal event, making it both rare and highly sought after by players. If you miss the event window, you will lose your chance until it returns, so you need to know when to get it. So, to help you with that, this guide explains exactly how the Cursed Mutation works and how to get it.
How to Get Cursed Mutation in Steal A Brainrot

The Cursed Mutation can only be obtained while the Cursed Event is active. This is a rotating seasonal event that runs for roughly fifteen minutes at a time and reappears every three hours throughout the event period, which lasts until February 6, 2026.
When the event starts, the entire map shifts into a red-and-black color scheme, strange symbols appear on walls and pillars, and a massive monster head spawns near the red conveyor belt entrance. These visual changes are your cue that the event has begun.
During this window, any Brainrots that spawn on the conveyor belt have a chance to appear with the Cursed Mutation. When you see a Brainrot with the red, corrupted visual effect, you need to get it immediately before another player does.
How to Get Cused Mutation - Alternate Method
Outside of direct spawns, the Cursed Event also added a special Cursed Spin Wheel. This wheel contains exclusive cursed-themed gear and a Cursed Secret Block that cannot be obtained elsewhere. Spinning the wheel gives you a random chance to receive a Cursed-mutated Brainrot, making it a good alternative if you are unlucky with belt spawns, although results are entirely RNG-based.
Apart from this, you can also get this mutation from stealing. Since other players are also buying Cursed Brainrots during the event, their bases become easy targets. Stealing during the fifteen-minute event window is one of the fastest ways to get Cursed Brainrots.
Cursed Mutation - Effects & Appearance
Visually, the Cursed Mutation is impossible to miss. Affected Brainrots emit a deep red and black aura, accompanied by dark, corrupted textures that match the event’s theme. This appearance alone makes them stand out in any base and signals their limited-time exclusivity.
Mechanically, the mutation is treated as a high-value special mutation, significantly increasing the Brainrot’s desirability for both base value and trading. While the exact income multiplier is yet to be calculated, you can still expect the value to be over five times the base.
