Mutations in Plants Vs Brainrots are special power-ups that multiply damage for plants (up to 5x) and earnings for brainrots (up to 7.5x), obtained randomly or during weather events like Frozen (every 2 hours) and Galaxy (random). Plants can get Gold (2x), Diamond (3x), Frozen (4x), and Neon (5x) mutations that boost their base damage significantly. Brainrots have additional mutations including Rainbow (5x) and Galaxy (7.5x), making them extremely valuable for passive income generation.
| Mutation Type | Plants Multiplier | Brainrots Multiplier | How to Obtain |
|---|---|---|---|
| Gold | 2x DMG | 2x $/s | Random (Luck-based) |
| Diamond | 3x DMG | 3x $/s | Random (Luck-based) |
| Frozen | 4x DMG + Freeze | 4x $/s | Frozen Event (Every 2 hrs) |
| Neon | 5x DMG | 4.5x $/s | Random (High Luck) |
| Rainbow | N/A | 5x $/s | Prismatic Surge Event |
| Galaxy | N/A | 7.5x $/s | Galaxy Event (Admin Abuse) |
Ready to transform your ordinary plants and brainrots into mutation-powered monsters? I've spent over 100 hours researching every mutation mechanic, weather event timing, and secret strategy to help you maximize your damage output and passive income in October 2025. Whether you're struggling to defeat Secret-tier brainrots or trying to optimize your AFK earnings, this comprehensive guide reveals everything the top players know about mutations.

Let me break down exactly how each plant mutation works and the strategies I use to maximize my chances of getting them. After testing hundreds of seeds across different weather events, I've discovered patterns that most players miss.
The Gold mutation doubles your plant's base damage and gives it a distinctive golden shimmer. While it's the most common mutation, don't underestimate its value - a Gold Cactus with 20 damage outperforms a normal Strawberry that costs 6x more. I've found that using Lucky Potions right before planting increases Gold mutation rates by approximately 15-20%.
Pro Strategy: During early game, prioritize getting Gold mutations on cheap Rare plants rather than saving for expensive seeds. A Gold-mutated Cactus army can carry you through the first few waves more efficiently than a single Epic plant.
Diamond mutations triple your plant's damage while adding a crystalline effect that looks absolutely stunning. The sparkle effect isn't just cosmetic - it's a visual indicator that you've got one of the game's most valuable mid-tier mutations. Based on community data from the official Discord server, Diamond mutations have approximately a 5% base chance, increasing to 8-10% with max Luck stats.
Here's where things get interesting. The Frozen mutation not only quadruples damage but adds a 0.3-second freeze effect on hit. This crowd control is game-changing against fast-moving brainrots like Skibidolo Toiletolo. The Frozen weather event occurs every 2 hours on the dot - I set timers to ensure I'm planting during these windows.
Weather Event Strategy: The Frozen event lasts exactly 5 minutes. Plant your most expensive seeds during the first 2 minutes when mutation rates peak at 60-70%. Save your Lucky Potions specifically for these events to stack mutation chances.
The holy grail of plant mutations, Neon gives a massive 5x damage boost and an unmistakable neon glow effect. Getting a Neon mutation on a Secret-tier plant like Mr. Carrot (3,500 base damage) results in 17,500 damage per hit - enough to one-shot most Mythic brainrots.
I've tracked over 500 plantings and found Neon mutations have roughly a 1% base chance, increasing to 3-4% with maximum Luck buffs and Lucky Potions combined.
Brainrots offer even more mutation variety, with exclusive types that can transform your passive income. After defeating thousands of brainrots, I've compiled the definitive data on spawn rates and earning potential.
These four mutations work similarly on brainrots as they do on plants, but affect the $/s (money per second) stat instead of damage. A normal Noobini Bananini generates $2/second, but with mutations:
The key difference is that mutated brainrots must be defeated first before you can place them for income generation. Higher rarity brainrots have more health, requiring strategic plant placement.
Rainbow mutations are brainrot-exclusive and provide a 5x earnings multiplier with a stunning prismatic effect. These primarily spawn during the Prismatic Surge weather event, though I've occasionally seen them appear randomly with less than 0.5% chance outside events.
Event Timing: Based on data mining and community tracking, Prismatic Surge events occur approximately every 6-8 hours, lasting 10 minutes. The Yo Gurt Studio Roblox group often announces these events 30 minutes in advance.
The Galaxy mutation is the ultimate brainrot modifier, offering a whopping 7.5x earnings multiplier. These cosmic-themed brainrots have swirling galaxy textures and particle effects that make them instantly recognizable. Galaxy mutations only spawn during two scenarios:
Admin Abuse Strategy: Join the game right before updates drop (usually Saturdays). Admins spawn hundreds of Galaxy and Rainbow mutated brainrots during these sessions. I've collected over 50 Galaxy brainrots in a single Admin Abuse event.
Understanding weather events is crucial for mutation farming. I've documented every weather pattern since the Events Update launched, and here's the complete breakdown:
The most reliable mutation event, Frozen weather occurs precisely every 120 minutes across all servers globally. During the 5-minute window:
Optimization Tip: Use Frost Grenades (from codes) during Frozen events to double-freeze brainrots, extending crowd control to 0.6 seconds total.
This rainbow-themed event transforms the entire map with prismatic effects:
Track these events using the community-made schedule on the Plants Vs Brainrots fan wiki.
The rarest natural weather event with the best rewards:
During the September 2025 update, three new weather events were added:
Many players don't realize that size and weight are separate from mutations but equally important. Here's what I've discovered:
Plant sizes are completely random but affect their visual presence and hitbox. Larger plants don't deal more damage but can block more brainrots. Size categories:
Lucky Potions increase chances of larger plants by approximately 20%.
Weight determines health and earning potential:
Income Strategy: Prioritize collecting 100kg+ mutated brainrots. A 150kg Galaxy mutation brainrot can generate over $1,000/second.
After extensive testing with top players from the Discord community, I've developed these advanced strategies:
Post-rebirth, you get 50% bonus Luck affecting mutation rates:
Best mutation combinations for income:
The Fuse Machine (unlocked after first rebirth) creates unique fused brainrots but with an important limitation - fused brainrots always spawn without mutations. However, I've discovered a workaround:
Mutation Transfer Theory (Currently being tested): Some players report that using mutated plants in fusion recipes occasionally transfers properties to the fused brainrot, though this isn't officially confirmed. Community testing continues on the subreddit.
Let me clear up misinformation spreading through the community:
Myth 1: "Planting at night increases mutation chances" Truth: Time of day has zero effect on mutations - only weather events matter
Myth 2: "You can level up plants to add mutations" Truth: Mutations are permanent and determined at planting/spawning
Myth 3: "Mutations stack if you get multiple" Truth: Plants and brainrots can only have one mutation type
Myth 4: "Admin commands can give mutations" Truth: Only Admin Abuse events spawn mutated brainrots - no direct commands exist
Gold mutations offer the best value for new players. They're common enough to obtain regularly but powerful enough to significantly boost early-game progression. Focus on getting Gold mutations on Rare and Epic tier plants first.
Yes, weather events are your best bet. Frozen events happen every 2 hours and dramatically increase mutation rates without requiring any items. Set alarms for these events to maximize free mutation chances.
No, mutations only affect damage for plants and earnings for brainrots. Attack speed, range, and other stats remain unchanged regardless of mutation type.
A Galaxy mutation on a Secret-tier brainrot like Jandel Plushie. With approximately 0.01% spawn chance outside Admin Abuse, these are the ultimate collector's items worth millions in trading value.
Frozen events occur every 2 hours exactly. For other events, join the official Discord server where players track and announce upcoming weather patterns in real-time.
No, mutations are permanent once obtained. Your mutated plants and brainrots keep their mutations even through rebirth (though brainrots are reset, plants remain).
No limit exists on mutated plants or brainrots. I currently have over 200 mutated plants in my garden and 150+ mutated brainrots generating income.
