Cut Grass for Brainrots is one of those Roblox tycoon games that looks simple on the surface until you realize your Brainrot units can transform into supercharged variants that multiply your earnings by up to 6x. These are called mutations, and knowing how each one works is the difference between grinding for hours and watching your cash-per-second (CPS) skyrocket in minutes. There are currently four mutations in the game, each with its own spawn behavior and value multiplier, and this guide breaks all of them down so you know exactly what to hunt.
Mutations are special visual and functional variants of your standard Brainrot units. When a Brainrot spawns with a mutation, it looks noticeably different from its base form and carries a passive income multiplier that stacks on top of whatever the base unit already generates. Collecting mutated Brainrots and slotting them into your active team is one of the fastest ways to push your CPS into the billions and beyond.
Developed by Very Green Grass and released on February 19, 2026, Cut Grass for Brainrots currently has exactly four mutation types. The rarity and accessibility of each one varies significantly, so prioritizing the right targets early can save you a lot of wasted time.
Here is every mutation currently available, how to obtain it, and the multiplier it applies to your Brainrot's income:
| Mutation | How to Get It | Value Multiplier |
|---|---|---|
| Gold | Spawns naturally across the map, identifiable by a shiny golden appearance | 1.5x |
| Diamond | Found throughout the map like Gold but shinier, with "Diamond" in the unit name | 2.5x |
| Rainbow | Rare spawn with a low appearance rate, colorful visual makes it stand out | 4x |
| Electro | Exclusive to the Electro event (10-minute window, repeats every 40 minutes) | 6x |
The Gold mutation is the most accessible of the four. These units appear with a noticeably shiny golden sheen and can be found scattered across the map in standard zones. While 1.5x might not sound impressive compared to later mutations, stacking multiple Gold variants in your team during early-game play gives you a meaningful income edge before you can access rarer spawns.
The Diamond mutation works similarly to Gold in terms of spawn behavior, appearing across the map without any special conditions. The visual difference is a much more intense shine and the word "Diamond" appearing in the unit's name. At 2.5x, this mutation is a solid mid-game upgrade and worth swapping into your active slots whenever you find one.

Gold vs Diamond mutation visuals
The Rainbow mutation is where things get exciting. These colorful variants are noticeably rarer than Gold or Diamond, meaning you will not stumble across them as casually. The striking multi-colored appearance makes them easy to spot when they do show up, so keep your eyes open while cutting through any zone. At 4x, a Rainbow Brainrot in your lineup is a major CPS jump worth chasing.
The Electro mutation is the clear top-tier option and the one every serious player should be farming. At 6x the normal income rate, a single Electro Brainrot can dramatically shift your entire CPS output. The catch is that Electro mutations are time-locked behind the Electro event, which runs for 10 minutes and then resets on a 40-minute cooldown.
When the Electro event triggers, lightning strikes create designated spawn spots across the map. Drop whatever you are doing and sprint to those locations immediately. The window is tight, and missing an Electro spawn means waiting almost an hour for the next opportunity.
The method for obtaining mutations depends entirely on which type you are targeting:
If you are asking which mutation to focus on, the answer depends on where you are in your progression:
Slotting even one Electro Celestial unit (a Celestial Brainrot with the Electro mutation) into your active team can push earnings into the billions or trillions of CPS range. These are the rarest possible combinations since Celestial units themselves only spawn every 10 minutes in the white and pink Celestial Zone at the map edge, and they despawn after just 60 seconds.
