Cookie Run Kingdom’s Chain of Silent Beast Raid (October 2025) Master Rank Guide
Breaking into Master and Master X rank in Cookie Run: Kingdom’s Chain of Silent Beast Raid demands precision, optimal team…
I’ve been absolutely obsessed with Roblox’s Grow a Garden lately, and let me tell you the Chubby Chipmunk update that just dropped has completely transformed my farming strategy. As someone who’s spent countless hours perfecting my garden layouts, this fall-themed event brings six nutty new seeds that are honestly some of the best additions we’ve seen all year.
The moment I logged in and saw those adorable chipmunks munching on my crops, I knew this update was going to be special. After spending the entire day testing every single new seed, experimenting with different farming techniques, and grinding through the reward track, I’m here to share everything you need to know about all new seeds in the Grow a Garden Chubby Chipmunk update.
The Chubby Chipmunk update launched on October 4, 2025, running until October 11, and it’s basically a fall harvest celebration packed with nutty goodness. This isn’t just another seasonal event—it introduces a completely unique mechanic where you raise your own Chubby Chipmunk pet by feeding it fruits from your garden.
Here’s what makes this update stand out from previous events like Summer Harvest or Fall Market: the chipmunk gains weight as it eats your crops, and the heavier it gets, the better rewards you unlock. I’m talking premium seeds, exclusive furniture, and those coveted Nutty Chests that everyone’s grinding for right now.
The update brings six brand-new nut-themed seeds, multiple new pets (including variations of chipmunks and even a Chinchilla), quality-of-life improvements, and a fresh weather system that adds even more atmosphere to your garden. Plus, there’s the traditional Admin Abuse session that happened an hour before launch—if you missed it, don’t worry; the main event still has plenty to offer.
I’ll be honest—when I first heard about another limited-time event, I was worried it would feel like a repetitive grind. But the Chubby Chipmunk event hits different. There’s something incredibly satisfying about watching your little chipmunk buddy waddle around your garden, munching on crops and slowly getting chubbier as you progress.
What really hooked me was the progression system. Unlike other events where you just collect currency mindlessly, this one rewards active engagement with your garden. Every time my chipmunk eats a fruit, there’s a chance it spawns an Acorn collectible, which gives random event rewards. The weight-based reward tiers add this perfect layer of strategy—do I submit my chipmunk now for a guaranteed chest, or keep feeding it to reach the next milestone?
The fall aesthetic is absolutely gorgeous too. My garden’s never looked better with those orange Persimmons scattered between woody Hazelnuts and classic Acorns. It genuinely feels like I’m managing an autumn orchard, and the new weather effects make everything feel more alive and seasonal.
After hours of grinding through both the reward track and opening Nutty Chests, I’ve compiled the definitive list of all six new seeds. Trust me, knowing exactly how to obtain each one will save you tons of time.
| Seed Name | How to Get It | Harvest Type | Base Sell Price | Drop Rate |
|---|---|---|---|---|
| Acorn Squash | Chubby Chipmunk Reward Track (5.88kg weight) | Multiple | 31,000 Sheckles | N/A (Guaranteed) |
| Ferntail | Chubby Chipmunk Reward Track (24.99kg weight) | Multiple | 12,000 Sheckles | N/A (Guaranteed) |
| Pecan | Chubby Chipmunk Reward Track (50kg weight) | Multiple | 14,000 Sheckles | N/A (Guaranteed) |
| Hazelnut | Nutty Chest / Exotic Nutty Chest | Multiple | 22,500 Sheckles | Common |
| Persimmon | Nutty Chest / Exotic Nutty Chest | Multiple | 45,000 Sheckles | Uncommon |
| Acorn | Nutty Chest / Exotic Nutty Chest | Multiple | 150,000 Sheckles | 1% (Rare) |
Important note: All of these seeds have multiple harvest types, meaning you can collect from them multiple times before they need replanting. This is huge for profit optimization, especially with the rarer seeds like Acorn and Persimmon.
The Acorn seed is by far the hardest to obtain with only a 1% drop rate from Nutty Chests, but when I finally got one after opening my seventh chest, the excitement was real. That 150,000 Sheckles base price makes every harvest feel like hitting the jackpot.
Through the Chubby Chipmunk Reward Track:
Getting the first three seeds (Acorn Squash, Ferntail, and Pecan) is straightforward but requires dedicated chipmunk feeding. Here’s my proven strategy:
I reached the 5.88kg milestone for Acorn Squash within the first three hours by focusing on feeding mutated crops. The mutations make a massive difference—a triple-mutated fruit can push that gain chance up significantly.
Through Nutty Chests:
The chest route requires more luck but can net you the rarest seed (Acorn) if RNG favors you:
After testing every single seed with various mutations and farming setups, I can confidently rank them by actual value and practicality.
Acorn is the undisputed champion of this update. Yes, it’s ridiculously rare at 1% from Nutty Chests, but that 150,000 Sheckles per harvest is absolutely insane. When I finally got one and planted it with a decent mutation setup, each harvest was netting me over 200,000 Sheckles. If you’re serious about maximizing profits during this event, grinding for Acorn should be your priority.
Acorn Squash is the accessibility king. You’re guaranteed to get it early on the reward track, and with a solid 31,000 Sheckles base value plus multiple harvests, it’s become my reliable money-maker. I’ve got an entire plot dedicated to these now, and they’ve consistently outperformed many of my older seeds.
Pecan sits at the end of the reward track (50kg chipmunk weight), which means you’ll need to grind a bit longer. But trust me, it’s worth it. The 14,000 Sheckles base price is respectable, and these look gorgeous in your garden with their distinct brown coloring.
Persimmon adds that beautiful orange pop to your autumn garden aesthetic while offering decent returns at 45,000 Sheckles per harvest. I use these strategically between my nut crops for visual variety, and they’ve been consistent performers profit-wise.
Hazelnut is pretty common from chests, which means you’ll probably accumulate several without trying too hard. At 22,500 Sheckles, it’s not breaking any records, but multiple harvest capability keeps it relevant.
Ferntail has the lowest base value at just 12,000 Sheckles, but here’s where it gets interesting—this seed has incredible mutation potential. I’ve seen Ferntails with the right mutation combinations sell for 10x their base value. Don’t sleep on this one just because the initial numbers look weak.
After extensive testing, I’ve discovered some techniques that dramatically boost your seed efficiency during this event:
The Mutation Priority System:
Not all mutations are equal, especially during a limited-time event. Focus your mutation efforts on:
I keep dedicated mutation plots with optimal sprinkler placement specifically for these high-priority seeds. The patience pays off when you harvest a triple-mutated Acorn for half a million Sheckles.
Garden Layout Optimization:
My current setup maximizes chipmunk feeding efficiency while maintaining profit flow:
This layout ensures my chipmunk constantly has food while protecting my most valuable plants.
Here’s something I learned the hard way: don’t harvest everything at once. Stagger your crop maturity times so your chipmunk always has something to munch on. Consistent feeding = consistent weight gain = faster reward progression.
I use a simple rotation system:
I made every single one of these errors in my first few hours, so learn from my pain:
Mistake #1: Planting Rare Seeds Immediately
The moment I got my first Acorn seed, I planted it without any preparation. No mutation boosters, no optimal conditions, nothing. That harvest was disappointing compared to what it could have been. Always prep your plot before planting rare drops.
Mistake #2: Ignoring Chipmunk Weight Milestones
Some players hyperfocus on collecting Acorns and forget the entire reward track exists. Those guaranteed seeds at specific weight milestones are literally free—don’t miss them by neglecting your chipmunk’s diet.
Mistake #3: Selling Event Seeds Too Early
I almost made this massive blunder. Some of these seeds (especially Acorn and Pecan) will likely retain significant value even after the event ends. Consider hoarding a few for post-event trading rather than selling everything immediately for quick Sheckles.
Mistake #4: Not Using Mutations Properly
Mutations can double, triple, or even quadruple your seed values. I see so many players just planting event seeds without any mutation strategy. Use your sprinklers, wait for optimal conditions, and actually plan which mutations you want before harvesting.
With only one week to complete everything (October 4-11), efficiency matters. Here’s my speedrun approach:
Day 1-2: Chipmunk Weight Focus
Dedicate the first 48 hours purely to fattening up your chipmunk. Feed it constantly, use mutated crops, and push hard to unlock all three reward track seeds. I hit 50kg by the end of day two with consistent feeding every hour.
Day 3-4: Chest Grinding Phase
Now that you have the guaranteed seeds, shift focus to collecting Acorns for Nutty Chest purchases. This is your best window for hunting that elusive 1% Acorn seed before everyone else floods the market.
Day 5-6: Mutation Optimization
With all seeds obtained, spend these days perfecting your mutations on the valuable ones. This is when you transform good seeds into incredible profit machines.
Day 7: Final Harvest & Preparation
The last day should be about maximizing final harvests and preparing for post-event. Decide what you’re keeping versus selling, organize your inventory, and enjoy the fruits of your labor.
The chest system in this update deserves its own breakdown because understanding the mechanics can save you serious Robux or grinding time.
Regular Nutty Chests contain:
Exotic Nutty Chests offer:
From my personal experience opening 12 regular chests and 3 exotic ones, the exotic chests feel worth it if you’re specifically hunting for Acorn seeds. I got two Acorns from three exotic chests versus zero from twelve regular ones. Your mileage may vary, but the math seems favorable for rare hunting.
For Casual Players:
Focus on Acorn Squash and Hazelnut. Both are relatively easy to obtain and don’t require intense optimization to be profitable. You can play at your own pace without feeling like you’re missing out on massive gains.
For Profit-Focused Farmers:
Acorn and Persimmon should be your entire world right now. Every hour you spend grinding toward these pays dividends. Set up dedicated mutation plots and optimize every single harvest.
For Collectors:
You want one of everything, obviously. Prioritize the reward track first (guaranteed seeds), then methodically work through chest openings for the remaining three. Keep at least one of each seed unplanted as a collection trophy.
For Short-Session Players:
Pecan and Ferntail work great if you can only log in once or twice daily. Their growth times align well with 12-hour check-in schedules, and you won’t feel pressured to constantly monitor your garden.
While this guide focuses primarily on seeds, the new pets significantly impact your farming strategy:
Chubby Chipmunk (the main event pet) directly influences seed acquisition through its weight-based reward system. Keep it well-fed with high-value crops to maximize progression.
Farmer Chipmunk reportedly has abilities that boost crop growth rates—perfect for speeding up those event seed maturity times.
Idol Chipmunk seems to offer passive Sheckle bonuses, which compounds nicely when you’re mass-harvesting expensive seeds like Acorn.
Chinchilla is still somewhat mysterious, but early reports suggest it might improve mutation chances or quality.
I’m currently running a setup with both the Chubby Chipmunk and Farmer Chipmunk active, and the synergy between faster growth and consistent feeding creates a really smooth loop.
Since your reward progression literally depends on how chubby your chipmunk gets, here are my tested weight-gain optimization techniques:
Feed mutated crops exclusively whenever possible. Remember: each mutation adds 3.5% to the base 15% weight gain chance when feeding. A triple-mutated fruit gives you roughly a 25% chance versus 15% with standard crops.
Time your feeding sessions around your playtime. The chipmunk naturally eats every 5 minutes, but manual feeding can accelerate weight gain significantly during active sessions.
Maintain a diverse crop selection in your feeding zone. If your chipmunk runs out of non-favorited crops to eat naturally, you’re losing passive weight gain opportunities.
Track your weight milestones. I keep a simple notepad tracking:
This helps maintain focus when the grind feels long.
One question I kept seeing in the community: “Will these seeds retain value after October 11?”
Based on previous Grow a Garden event patterns, event-exclusive seeds typically remain in the game but become much harder to obtain. This creates a fascinating post-event economy where early grinders (like us) can capitalize on seed scarcity.
My investment strategy for this event:
The key is balancing immediate Sheckle gains against potential long-term value. I’m personally betting that Acorn seeds specifically will command premium prices in a few weeks once the event ends and supply dries up.
If you’re already running established garden builds, integrating these new seeds requires some planning:
Don’t completely overhaul your garden just for the event. I made this mistake initially and tanked my regular income streams. Instead, dedicate 20-30% of your space to event content while maintaining your proven setups.
Synergize with existing crops. Persimmon’s color profile works beautifully between existing fall crops. Acorn Squash can slot into any vegetable-themed plot. Think about aesthetic cohesion even when chasing profits.
Maintain mutation lines. If you’ve been working on specific mutation breeding projects, don’t abandon them. Event seeds can actually benefit from your existing mutation infrastructure—just redirect it temporarily.
For the detail-oriented farmers, here are the specific growth mechanics I’ve tested:
Growth Time Estimates:
Optimal Conditions: All event seeds benefit from standard growth boosters—sprinklers increase mutation chances, proper spacing improves yields, and weather effects seem to slightly boost harvest quality during rainy conditions.
Harvest Multiplicity: Each seed averages 3-5 harvests before requiring replanting. Acorn tends toward the higher end (5-6 harvests observed), while Ferntail sits lower (3-4 harvests typical).
Based on developer patterns, these seeds will likely remain obtainable but with significantly reduced drop rates. The event provides the easiest acquisition window, so prioritize collecting now rather than hoping for post-event availability.
Acorn Squash is your day-one priority since it’s guaranteed from the reward track at just 5.88kg chipmunk weight. After that, grind toward either Pecan (reward track) or save for Nutty Chests to hunt Acorn seeds.
If you’re specifically hunting for the 1% Acorn seed drop, the improved rates in Exotic Chests make them reasonable value. For general seed collection, regular Nutty Chests are fine—you’ll get everything eventually with patience.
Absolutely! All standard mutation mechanics apply to event seeds. In fact, mutating rare event seeds often provides some of the highest value crops in the entire game right now.
Your chipmunk pet remains permanently in your collection, but the weight-based reward system ends with the event. You’ll keep everything you’ve unlocked.
This depends on your server and trading settings, but generally yes—event seeds are tradeable items. Expect premium prices for rare seeds like Acorn in player markets.
I recommend planting 1-2 immediately to start generating profit, while saving extras for potential future value or trading. Never plant your last copy of a rare seed without backups.
RNG varies wildly, but expect to open 8-15 regular chests to collect Hazelnut, Persimmon, and Acorn with reasonable luck. The Acorn’s 1% rate makes it the bottleneck.
This Chubby Chipmunk update has genuinely reinvigorated my love for Grow a Garden. Between hunting for that elusive Acorn seed, watching my chipmunk waddle around getting progressively chubbier, and optimizing my autumn garden aesthetic, I’ve barely looked at my other games this week.
The beauty of this event lies in its accessibility—whether you’re a hardcore grinder pushing for perfect mutations on every seed or a casual player just enjoying the fall vibes, there’s something rewarding here. My garden has never looked better with those warm oranges from Persimmons mixing with the earthy browns of Pecans and Hazelnuts.
If you haven’t started grinding yet, there’s still plenty of time before October 11 to collect all six seeds and maximize your rewards. Set up your garden, grab that free Chubby Chipmunk, and start feeding it everything in sight. The satisfaction of unlocking each new seed tier while building your perfect autumn paradise is exactly what makes Grow a Garden such an addictive experience.
Happy farming, and may your chipmunks grow fat and your harvests overflow with mutated Acorns worth millions!
