How to Get Cerberus in Steal a Brainrot (January 2026) Complete Guide
If you’ve been grinding Steal a Brainrot lately, you’ve probably heard about Cerberus—the three-headed mythical beast that’s taking the Roblox…
The Sprout Studies Event has transformed Plants vs Brainrots completely. Instead of grinding endless waves or hunting bosses, I can now experiment with seeds in a purple laboratory to unlock powerful mutated plants. After spending the entire weekend testing every seed type and tracking mutation rates, I’ve discovered strategies that nobody else is talking about yet. This isn’t just another event – it’s a completely new way to build your garden.
Let me break down everything you need to dominate this event before it disappears.
The Sprout Studies Event launched on January 10, 2026, replacing the Gym from the previous update. Located on Central Island, this purple laboratory introduces a seed mutation system that works differently from anything we’ve seen before in the game.
Here’s what makes this event special:
| Feature | Details |
|---|---|
| Location | Central Island (Purple Laboratory) |
| Requirements | Rebirth 1 + 1,000,000 Cash |
| Duration | 7 days (ends approximately January 17, 2026) |
| Main Mechanic | Seed submission and mutation |
| Total Milestones | 25 reward tiers |
| Mutation Timer | Maximum 5 minutes per seed |
Unlike typical Plants vs Brainrots events where you lose items permanently, the Sprout Studies system returns your seeds as upgraded mutated versions. Every submission earns milestone progress instantly, while your seed undergoes transformation in the background.
Getting access to the Sprout Studies lab requires meeting specific prerequisites. I’ll walk you through the exact steps I took to unlock everything.
Before you can participate in Sprout Studies, you need:
Step 1: Reach Central Island
From your base, look for the mirror portal. Interact with it to teleport to Central Island. If you haven’t unlocked Central Island yet, you’ll need to reach Rebirth 1 first and pay the 1,000,000 Cash entry fee.
Step 2: Locate the Purple Laboratory
Once on Central Island, you’ll immediately notice the purple laboratory building. It replaced the Gym from the Gym Gains update. The lab has two main components:
Step 3: Prepare Your Seeds
Check your inventory for any plant seeds. The seed type determines what mutated plant you’ll receive, but any seed works for earning milestone rewards. I recommend starting with common seeds for your first few submissions to understand the system.
Central Island became accessible during the Storyline Update back in October 2026. If you’re a newer player who hasn’t reached Rebirth 1 yet, focus on these priorities:
The 1,000,000 Cash requirement might seem steep for beginners, but most players reach this milestone naturally while progressing to Rebirth 1.
The Sprout Studies mutation system operates on a dual-reward structure that I haven’t seen in any other Roblox game. Every seed submission triggers two separate reward mechanisms simultaneously.
When you submit a seed to the external machine, three things happen instantly:
The seed doesn’t disappear from your inventory permanently. Instead, it moves to the secondary mutation machine located behind the scientist inside the laboratory. This machine handles the actual transformation process.
The mutation timer varies based on seed rarity and type, but I’ve found the maximum wait is capped at 5 minutes. Here’s what I discovered during my testing:
Common Seeds (Sunflower, Pea Shooter):
Rare Seeds (Dragon Fruit, Eggplant):
Epic Seeds (King Limone, Mango):
Every seed has an equal chance of rolling one of six possible mutations. After submitting over 50 seeds myself, my results aligned almost perfectly with the official drop rates:
| Mutation Type | Drop Rate | Multiplier Effect |
|---|---|---|
| Abomination | 85% | 1.5x DPS |
| Corrupted | 5% | 2x DPS |
| AmpedUp | 4% | 2.5x DPS |
| Diamond | 3% | 3x DPS |
| Frozen | 2% | 4x DPS + Freeze |
| Neon | 1% | 5x DPS |
As you can see, Abomination mutations dominate your results. The rarity of Frozen and Neon makes them extremely valuable, but you’ll need patience (or lots of seeds) to obtain them.
The Sprout Studies mutations differ from regular weather-based mutations in several critical ways:
Guaranteed Mutation: Every seed submitted through Sprout Studies receives a mutation. Unlike planting during weather events where mutations are chance-based, this event guarantees you’ll get something.
No Weather Dependency: You don’t need to wait for specific weather patterns like Icy Blizzard or Prismatic Surge. The mutation type is determined by RNG when the timer completes.
Permanent Acquisition: These mutations persist across rebirths, just like standard mutations. I tested this by rebirthing with three Sprout Studies mutations, and all three remained in my inventory.
Stackable Progress: Unlike the Mutation Machine on Central Island which requires two identical plants with different mutations, Sprout Studies works with single seed submissions. This makes it much more accessible for newer players.
While any seed works for gaining milestone progress, I’ve developed a strategy for maximizing value:
For Milestone Rushing: Use your most common seeds (Sunflower, Peashooter). Since milestone progress appears identical regardless of seed rarity, save your rare seeds for later.
For Mutation Hunting: If you’re specifically hunting Frozen or Neon mutations, use your highest DPS plant seeds. A Neon King Limone has exponentially more value than a Neon Sunflower.
For Efficient Farming: Submit seeds in batches of 5-10 at a time. The 5-minute maximum timer means you can process 12 seeds per hour at peak efficiency. This stacks nicely with the milestone system.
I tested submitting 20 Sunflower seeds in rapid succession, and all 20 entered the mutation queue simultaneously. The timers ran in parallel, meaning I received all 20 mutated plants within a 5-minute window rather than waiting 100 minutes total.
The milestone reward system offers 25 tiers of increasingly valuable items. Unlike previous events where rewards scaled gradually, Sprout Studies front-loads some premium rewards in the early tiers, making it accessible even if you can’t complete all 25.
Based on confirmed community data and my own progression, here’s every reward available:
| Tier | Rewards | Value Analysis |
|---|---|---|
| 1 | 1.2 Billion Money | Solid cash injection for rebirths |
| 2 | 633.7 Million Money, 3x Premium Water Bucket | Water buckets are rare – worth grabbing |
| 3 | 4x Frost Grenade, Alessio Plant | Alessio is a mid-tier plant but useful early |
| 4 | Elefanto Cocofanto, Shiny Base Card Pack | Elefanto is one of the better brainrots |
| 5 | Pre-Workout | Speeds up plant attacks temporarily |
| 6 | 1.5 Billion Money, Las Tralaleritas | Las Tralaleritas is a top-tier brainrot |
| 7 | Firework Bazooka, Fire Potion | Both excellent for clearing waves |
| 8 | 1 Billion Money, Sunflower Seed | Basic but stacks with other rewards |
| 9 | 950.5 Million Money, Temporal Canister, Dragon Fruit Seed | Dragon Fruit is valuable for mutations |
| 10 | Bee Launcher, Rinoccio Verdiniw | Bee Launcher is surprisingly effective |
| 11 | Bombini Gussini | Another strong brainrot option |
| 12 | 3x EXP Pot, Sunflower Seed | EXP pots accelerate plant leveling |
| 13 | 1.1 Billion Money | Pure cash tier |
| 14 | 2x Temporal Canister, Dragon Fruit Seed | More Dragon Fruit seeds for mutations |
| 15 | Pre-Workout, Bottellini | Second Pre-Workout very useful |
| 16 | 2x Shiny Base Card Pack, 3x EXP Pot | Card packs can contain rare cards |
| 17 | 528 Million Money, Eggplant Seed | Eggplant is underrated for mid-game |
| 18 | 1.5 Billion Money | Another cash boost |
| 19 | 2x Size Potion | Size potions are cosmetic but fun |
| 20 | 529.4 Million Money, Eggplant Seed | Second Eggplant seed |
| 21 | Witch Potion, Kiwissimo | Kiwissimo is a decent plant |
| 22 | Pickup Pot | Helpful quality-of-life item |
| 23 | 1 Billion Money, 2x EXP Star | EXP Stars are rarer than pots |
| 24 | TBA | Information pending |
| 25 | Rana Scienziato, Shrink Ray, Hellxino Seed | Grand finale rewards |
Early Game Players (Tiers 1-10): Focus on reaching Tier 6 minimum. Las Tralaleritas is one of the best brainrots for passive income generation, and the 1.5 Billion Money helps fund your next rebirth.
Mid Game Players (Tiers 11-20): Push toward Tier 16 for the Shiny Base Card Packs. These packs have higher drop rates for Epic and Limited cards that significantly boost your combat effectiveness.
End Game Players (Tiers 21-25): The final tiers contain exclusive items like Rana Scienziato (the scientist brainrot) and Hellxino Seed. These items don’t appear in any other event or shop, making them must-haves for collectors.
Each seed submission grants one point of milestone progress. With 25 milestones, you need approximately 25-30 seed submissions to complete the entire reward ladder.
If you submit seeds efficiently (managing the 5-minute timer), you can complete all 25 milestones in roughly 12-15 hours of active play spread across the event’s 7-day duration. That’s only 2 hours per day, which is very manageable.
After completing my own milestone ladder and testing various approaches, I’ve identified several advanced strategies that aren’t obvious from the basic event mechanics.
Instead of submitting seeds one at a time, collect seeds in batches of 10-20, then submit them all within a 2-3 minute window. This creates several advantages:
Advantage 1: Psychological Momentum Opening 10-20 mutated plants simultaneously feels far more rewarding than watching individual mutations trickle in. It also helps you avoid the frustration of getting 10 consecutive Abomination mutations.
Advantage 2: Milestone Rushing Batch submissions let you jump multiple milestone tiers instantly. This is particularly valuable if you’re short on time and want to hit specific reward breakpoints before the event ends.
Advantage 3: Parallel Timer Management Remember, mutation timers run simultaneously. 20 seeds submitted within 3 minutes will all complete their mutations within an 8-minute total window, not 100 minutes.
How I Do It:
Not all players realize that common seeds have value during Sprout Studies. Here’s how to optimize your seed economy:
Trade for Common Seeds: If you’re struggling to find enough seeds, check the trading community. Many players will trade common seeds for minimal value because they don’t realize the Sprout Studies application.
Convert Brainrots to Plants: If you have excess brainrots, consider fusing them at the Fusion Machine to create plant seeds. This is less efficient than direct seed farming but works when you’re desperate to hit the next milestone tier.
Shop Monitoring: The in-game shop occasionally stocks seeds for Cash or Robux. During Sprout Studies, buying these seeds becomes more valuable than usual because they’re effectively buying milestone progress and guaranteed mutations.
Code Redemption: Check for new codes daily during the event. Even one free rare seed could result in a Neon mutation if you’re lucky.
With only 7 days to complete the event, planning your play sessions matters.
Day 1-2 (Milestone Rush): Use common seeds exclusively to push through the first 15-20 milestones. Don’t waste rare seeds yet because you don’t know if you’ll have time to complete the event.
Day 3-4 (Reward Assessment): Evaluate which rewards you absolutely need. If you’ve hit your target tier, switch to hunting specific mutations with rare seeds.
Day 5-6 (Rare Seed Gambling): With most milestones complete and the event ending soon, this is when you submit all your Dragon Fruit, Mango, and King Limone seeds hunting for Frozen and Neon mutations.
Day 7 (Final Push): Submit everything you have left. Any seeds not submitted before the event ends lose their Sprout Studies value and revert to normal mutation chances.
Admin Abuse events occur during the first 30-60 minutes after major updates. During Sprout Studies, we’ll likely see at least one Admin Abuse event.
Dual Event Strategy:
This maximizes efficiency by utilizing the mutation timer downtime.
Choosing which plants to submit for mutation can dramatically impact your garden’s effectiveness. Based on extensive testing and community feedback, here are the top priorities:
King Limone
Mango
Dragon Fruit
Eggplant
Alessio
Sunflower
Peashooter
For players with limited seeds, follow this priority order:
This approach ensures you don’t waste rare seeds on milestone progress while still maximizing your chances of getting valuable mutations.
After watching other players struggle with Sprout Studies, I’ve identified several common mistakes that significantly reduce efficiency.
Many players get excited and immediately submit their best seeds (King Limone, Mango) for the first few milestones. This is wasteful because:
Solution: Save all rare seeds until you’ve reached at least Tier 20 using commons.
Some players submit one seed, wait for the mutation, then submit another. This extends a 2-hour process into a 10-hour grind unnecessarily.
Solution: Batch submit 10-20 seeds at once. All timers run simultaneously, completing in just 5 minutes total.
Plants vs Brainrots frequently releases new codes during events. Missing these codes means missing free seeds that could push you over the next milestone tier.
Solution: Bookmark code tracking websites and check daily during the event.
While mutations persist across rebirths, some players report losing milestone progress when rebirthing during active events.
Solution: Complete all 25 milestones before rebirthing, or wait until the event ends entirely.
In the rush to level up plants, some players accidentally feed their Frozen or Neon mutations to the Plant XP Extractor, permanently losing them.
Solution: Favorite your rare mutations in your inventory to prevent accidental deletion or consumption.
Focusing exclusively on Neon mutations (1% drop rate) leads to frustration and wasted seeds when you could be building a diverse mutation collection.
Solution: Appreciate Frozen (2%) and Diamond (3%) mutations as valuable alternatives. A Frozen Mango is better than no rare mutations at all.
Admin Abuse events provide multiplied drop rates for seeds. Missing these events while focusing solely on Sprout Studies slows your overall progress.
Solution: Participate in both events simultaneously using the dual-strategy method I outlined earlier.
The event launched on January 10, 2026, and runs for approximately 7 days, ending around January 17, 2026. The exact end time hasn’t been officially announced, but based on previous event patterns, expect it to conclude when the next major update releases.
No. Seeds submitted to Sprout Studies undergo a mutation process and return to your inventory as mutated versions after a maximum 5-minute timer. This is completely different from other events where consumed items disappear forever.
Mutated plants appear directly in your inventory automatically when the timer completes. There’s no manual claim step, so as long as your submission completes before the event ends, you’ll receive your mutation. However, I recommend not submitting seeds in the final 10 minutes of the event just to be safe.
Yes. You can submit 50 Sunflower seeds if you want. Each submission grants milestone progress and rolls for a mutation independently. There’s no limit on seed types or quantities.
No. Whether you submit a common Sunflower seed or a rare King Limone seed, the mutation drop rates remain identical (85% Abomination, 5% Corrupted, 4% AmpedUp, 3% Diamond, 2% Frozen, 1% Neon). The only difference is the base stats of the resulting plant.
The fastest seed acquisition methods are:
Current testing suggests Sprout Studies only works with plant seeds, not brainrots. The event focuses exclusively on mutating plants. Brainrot mutations still need to be obtained through standard methods.
Yes. Mutations obtained through Sprout Studies function identically to standard mutations and contribute to your Mutation Index completion. If you’re a collector trying to fill out the index, this event provides an excellent opportunity.
Yes. Sprout Studies mutations can be merged with other mutations using the Mutation Machine on Central Island. This lets you create hybrid mutations like Frozen plus Neon for combined effects.
Based on similar events, milestone progress should persist across rebirths. However, some players report losing progress, so I recommend completing as many milestones as possible before rebirthing.
Tier 25 rewards include Rana Scienziato (the scientist brainrot), Shrink Ray, and Hellxino Seed. These are event-exclusive items that likely won’t be available after Sprout Studies ends, making them valuable for collectors.
Currently, there’s no confirmed method to speed up mutation timers. The 5-minute maximum appears to be hard-coded. Some players speculate certain potions might help, but this hasn’t been verified.
For combat effectiveness, prioritize King Limone or Mango. The high base DPS combined with Frozen’s freeze effect or Neon’s 5x multiplier creates the strongest plants in the game.
Absolutely. You need approximately 25-30 seed submissions to complete all milestones. With 7 days available and seeds obtainable through free methods, completing the event as a free-to-play player is entirely achievable.
As the event winds down, here are my final recommendations for getting the most value:
Time Management: Dedicate 2-3 hours daily to seed farming and submission. This pace lets you complete all 25 milestones while still hunting for rare mutations.
Seed Diversity: Don’t put all your eggs in one basket. Submit a mix of common and rare seeds to balance milestone progress with mutation hunting.
Community Resources: Join the Plants vs Brainrots Discord server for real-time code announcements, mutation rate updates, and trading opportunities.
Post-Event Planning: Once Sprout Studies ends, the Mutation Machine becomes your primary source for new mutations. Use this event to build a foundation of mutated plants that you can further enhance later.
Screenshot Your Collection: Document your rare mutations (especially Neon and Frozen) in case of any account issues or for showing off to the community.
The Sprout Studies Event represents the best opportunity we’ve had to acquire guaranteed mutations without relying on random weather patterns. Even if you only reach Tier 15-20, you’ll still walk away with valuable rewards and several mutated plants that will serve you well through future rebirths.
Make the most of these 7 days – the next event won’t be this generous with mutations.
