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’ll be honest with you when I first heard about the Chubby Chipmunk update dropping in Grow a Garden, I thought it would be just another routine Fall event. Boy, was I wrong. This update has completely transformed how I approach my garden layout, and the new seeds? They’re absolute game-changers for anyone looking to maximize profits while embracing that cozy autumn aesthetic.
The latest update brings six brand-new seeds to the game, each one perfectly themed around nuts, acorns, and everything that makes fall farming feel special. Whether you’re a free-to-play grinder like myself or someone who doesn’t mind splurging on Robux, this guide will walk you through everything you need to know about obtaining, growing, and profiting from these nutty additions.
Before diving into the seeds themselves, let me give you some context. The Chubby Chipmunk update (version 1.25.1) launched on October 4, 2025, and runs until October 11, giving us exactly one week to collect everything. This event replaced the somewhat tedious Seed Stages update, and I’ve got to say—it’s a massive improvement.
The update centers around a free event pet called the Chubby Chipmunk that you can grab from the event island. This adorable little critter has a unique mechanic where it eats fruits from your garden to gain weight. The heavier your chipmunk gets, the better rewards you unlock through the event’s reward track. It’s basically a feeding competition, but way more fun than it sounds.
What makes this update special is the introduction of Nutty Chests—a new type of loot box containing three exclusive seeds and three pets. You can earn these chests by progressing through the Chubby Chipmunk weight milestones or purchase Exotic Nutty Chests with Robux (199 for one, 575 for three, or 1,699 for ten).
Let me tell you what got me genuinely excited about this update. After grinding through the repetitive Seed Stages event for a week, the Chubby Chipmunk update feels like a breath of fresh autumn air. There’s something incredibly satisfying about watching your pet chipmunk waddle around the garden, occasionally munching on your crops while gaining weight.
The aesthetic alone is worth praising. Those warm orange and brown tones, the acorn-themed decorations, and the nutty crops create this perfect cozy farming vibe that I didn’t know I needed. I’ve completely redesigned my garden three times already just to fit the fall theme properly.
But beyond aesthetics, what really hooked me is the variety in seed acquisition methods. Some players prefer the steady grind of feeding their chipmunk to unlock reward track seeds. Others (with deeper pockets) enjoy the gacha-style excitement of opening Nutty Chests. I’ve been doing a mix of both, and it keeps the gameplay loop fresh and engaging.
The time-limited nature also adds this pleasant pressure. You know you only have seven days to collect everything, which makes every harvest count. I’ve caught myself staying up way too late just to check if my chipmunk has gained enough weight to unlock the next reward tier.
Alright, let’s get into the meat and potatoes or should I say, the nuts and acorns? Here’s every single new seed you can obtain during this event, organized by how you get them.
These three seeds are unlocked by feeding your Chubby Chipmunk until it reaches specific weight milestones:
These three seeds come from opening regular Nutty Chests or Exotic Nutty Chests:
After spending way too many hours optimizing my approach, I’ve developed a strategy that maximizes seed acquisition without burning through all your Robux. Here’s my step-by-step method:
As soon as you log in, head straight to the event island and claim your free Chubby Chipmunk pet. Don’t delay this—every minute counts when you’re working against a one-week timer.
Your chipmunk gains weight by eating fruits from your garden every approximately five minutes. Here’s how to maximize weight gain:
While your chipmunk passively eats every five minutes, you can also manually feed it harvested crops. This has a roughly 15% base chance to increase weight, which jumps significantly with mutated crops. I’ve been harvesting my best mutated fruits specifically for manual feeding sessions.
Pro tip: Feed your chipmunk right before logging off. That way, even while you’re offline, the passive eating mechanic continues working toward your weight goals.
Your chipmunk occasionally spawns Acorns around your garden when it eats. These Acorns grant random rewards, including currency you can use toward Nutty Chests. Never leave Acorns uncollected—I set a phone reminder to check every couple hours.
My recommendation is to focus entirely on maxing out your chipmunk’s weight before spending Robux on chests. Why? Because the reward track seeds (Acorn Squash, Ferntail, and Pecan) are guaranteed unlocks. You’ll get them no matter what if you put in the time.
I reached 50kg by day four using consistent feeding and garden optimization. That secured me all three reward track seeds without spending a single Robux.
Once you’ve unlocked the reward track seeds, decide your chest strategy based on your budget:
Free-to-Play Route: Save up currency from collected Acorns and event completion to buy regular Nutty Chests. You’ll probably get Hazelnut and Persimmon relatively easily, but Acorn requires some serious luck.
Budget-Conscious Route: Buy one or two Exotic Nutty Chests for better drop rates. The improved odds make a noticeable difference, especially if you’re hunting that 1% Acorn seed.
Completionist Route: If you absolutely need that Acorn seed, be prepared to invest in multiple Exotic Nutty Chest bundles. The 10-pack for 1,699 Robux offers the best value per chest if you’re going this route.
Here’s where the real profit potential lies. Once you have your seeds planted, focus on mutation optimization:
I got a Jackpot mutation on my Ferntail seed thanks to pure luck (and probably the Fortune Squirrel pet I had active), and that single plant sold for enough to buy three more Nutty Chests.
Not all seeds are created equal, and with limited event time, you need to know where to focus your energy. Based on my testing and market analysis, here’s my personal tier ranking:
Acorn – Yes, the 1% drop rate is brutal, but this seed represents the perfect combination of high value (150,000 Sheckles), thematic relevance, and multiple harvests. If you can get even one Acorn seed with a decent mutation, you’re set for the entire event. Plus, it’s just chef’s kiss for your garden aesthetic.
Pecan – The highest value reward track seed and guaranteed if you grind to 50kg. Multiple harvests at 140,000 Sheckles make this a money-printing machine. I’ve been running a dedicated Pecan plot that’s funded my entire Nutty Chest addiction.
Acorn Squash – Despite the lower price point (31,000 Sheckles), the value here lies in accessibility and a unique quality: both Acorn and Acorn Squash share the same average value of 123,123 Sheckles according to some game files, though displayed prices vary. The Acorn Squash is dramatically easier to obtain (just 5.88kg chipmunk weight), making it the best “bang for your effort” seed in the event.
Persimmon – The middle-child seed that nobody talks about enough. At 45,000 Sheckles per harvest with decent drop rates from chests, Persimmon offers reliable income. Plus, that orange pop against brown and green foliage? Beautiful.
Ferntail – Here’s the controversial take: Ferntail’s base value is terrible at 2,000 Sheckles (or 120,000 depending on source data), but with the right mutations, it transforms into an A-tier seed. The problem is that mutation farming takes time and luck. If you’re running out of event days, other seeds offer more reliable value.
Hazelnut – The most common chest seed at 22,500 Sheckles. It’s not exciting, but it’s dependable. Think of Hazelnut as your bread-and-butter crop for establishing a baseline autumn farm aesthetic while you grind for better seeds.
After making plenty of mistakes during my first couple days, I’ve learned some valuable lessons that I wish someone had told me upfront:
Create a dedicated “chipmunk feeding zone” separate from your main money-making plots. Fill this area with quick-growing, mutation-heavy crops specifically for your chipmunk to eat. This prevents your valuable mutated plants from becoming chipmunk snacks.
I use a three-section layout: feeding zone on the left, event seed showcase in the center, and profit farming on the right. Sprinklers cover all three areas, but the feeding zone gets priority watering.
Check your garden every five hours minimum. This aligns with the chipmunk’s eating cycle and ensures you’re collecting Acorns regularly. Set actual phone alarms if necessary—missing Acorn spawns means missing potential Nutty Chest currency.
Not all mutations are equal for these specific seeds. Here’s what I’ve found works best:
If you manage to pull the Farmer Chipmunk pet from Nutty Chests, immediately equip it when working with your nutty crops. That 1.56x growth speed boost is absolutely massive for an event that only lasts seven days. I calculated that this pet effectively gives you an extra 1.5 days of growth time over the week-long event.
Every Sheckle counts during this event. Here’s my money management approach:
Mistake 1: Favoriting all your plants. I did this initially and wondered why my chipmunk wasn’t gaining weight fast enough. Unfavorite plants you want the chipmunk to eat!
Mistake 2: Harvesting event seeds immediately. The first time I got Ferntail, I harvested it right away for 2,000 Sheckles. Two harvests later, I waited for mutations and sold for 85,000. Patience pays.
Mistake 3: Ignoring the event pet synergies. The new pets aren’t just collectibles—they have real gameplay benefits. The Idol Chipmunk restores hunger to other pets, which keeps your Farmer Chipmunk active longer.
Mistake 4: Not planning for post-event. These seeds become unavailable after October 11. If you want to keep farming them long-term, don’t sell everything—keep breeding stock planted.
Let’s be real—not everyone can (or wants to) drop Robux on Exotic Nutty Chests. If you’re going full free-to-play, here’s your action plan:
I’ve been running a secondary free-to-play account to test this strategy, and I currently have five of the six seeds without spending Robux. The only missing one? You guessed it—Acorn seed. But my Pecan profits have been phenomenal even without it.
One thing that confused me initially was the discrepancy between listed average prices and actual sale values. Here’s what I’ve learned about how seed pricing actually works in Grow a Garden:
The “average price” listed for each seed represents the baseline value you’ll receive for harvesting that crop with zero mutations. But here’s the secret: mutations can multiply your sale price by 10x or more.
Take my Ferntail example. Base value shows as 2,000 or 120,000 Sheckles depending on the source (game data seems inconsistent). But with a rare mutation, I’ve sold individual Ferntail harvests for over 200,000 Sheckles. That’s where the real money lives.
This means the traditional wisdom of “only plant high-value seeds” doesn’t always apply during this event. A low-value seed with excellent mutation potential can outperform expensive seeds with poor mutations.
Both Acorn and Acorn Squash reportedly share identical “huge chance” (1.11%) values in game files, and both list the same average value of 123,123 Sheckles. Yet the Acorn has a 1% drop rate from chests while Acorn Squash is a guaranteed reward track unlock. This doesn’t make much sense from a game design perspective, and I suspect there might be hidden stat differences we haven’t discovered yet.
My theory? The Acorn might have better mutation odds or hidden bonuses that justify its rarity. I’m desperately trying to get one to test this, but RNG has not been kind.
Here’s something most guides won’t tell you: this event ends on October 11, but your event seeds don’t disappear. I’ve been thinking strategically about post-event gameplay, and here’s my approach:
Keep at least two of each seed type planted permanently. Even after the event ends, these autumn-themed crops will be unavailable to new players, making them valuable for long-term mutation farming and aesthetic builds.
I’m dedicating an entire corner of my garden to a permanent “Fall Legacy Zone” featuring one of each event seed, surrounded by event decorations. It’ll be a nice reminder of this update while potentially generating ongoing profit from harvests.
Additionally, players who missed this event will eventually want these seeds for completion purposes. While we don’t have a player trading system yet, if that feature ever gets added, early event seed collectors like us will be sitting on valuable assets.
Yes, but you’ll need serious dedication and good RNG luck. The three reward track seeds (Acorn Squash, Ferntail, Pecan) are absolutely achievable free-to-play—I got all three in four days. Hazelnut and Persimmon from Nutty Chests are possible if you grind Acorn spawns for chest currency. The rare Acorn seed at 1% drop rate is extremely unlikely without buying multiple chests, but technically possible.
With optimized play—keeping your garden fully planted with multiple-harvest crops and checking every five hours to collect Acorns and manually feed mutated fruits—you can hit 50kg in three to four days. Casual play will take the full week. The key is maximizing both passive eating and manual feeding with high-mutation crops.
Your planted seeds remain functional and continue producing harvests normally. However, you won’t be able to obtain new seeds of these types once the event ends (until potentially a future re-run). This makes them limited-edition crops worth preserving.
Prioritize unlocking Acorn Squash at 5.88kg chipmunk weight as your first goal. It’s the fastest reward track seed to get and provides immediate income for funding Nutty Chests. Then push hard for Pecan at 50kg since it offers the best consistent profit among guaranteed seeds.
Yes! Event seeds follow identical mutation mechanics to regular crops. This means sprinklers, weather conditions, and pet abilities that boost mutation rates work exactly as they would on any other seed type. In fact, because these are new seeds with relatively high base values, good mutations can result in massive paydays.
If you’re specifically hunting the rare 1% Acorn seed, Exotic Nutty Chests offer better odds and are worth the premium price. For everything else, regular Nutty Chests are sufficient. I’d recommend buying one or two Exotic chests if you can afford it, then switching to regular chests for bulk opening.
Sort of. You can’t directly accelerate the passive eating cycle (every five minutes), but you can maximize weight gain per feeding by using mutated crops for manual feeding. Each mutation adds approximately 3.5% to the weight gain chance. Stack multiple mutations on a single fruit before feeding it to your chipmunk for best results.
You don’t need a massive garden to succeed in this event. A medium-sized plot (around 20–30 plant spaces) dedicated to chipmunk feeding, plus another 15–20 spaces for event seed cultivation is perfectly adequate. Quality matters more than quantity—focus on mutation optimization rather than raw plant count.
The Chubby Chipmunk update has genuinely rekindled my love for Grow a Garden after the somewhat stale Seed Stages event. There’s something magical about watching your little chipmunk friend waddle around munching on crops while you work toward unlocking these gorgeous autumn seeds. Whether you’re a completionist chasing that elusive Acorn seed or a casual player just enjoying the fall vibes, this event offers something for everyone.
My personal highlight has been completely redesigning my garden around these nutty crops. The warm orange and brown color palette creates this cozy farming atmosphere that makes me want to spend hours just watching my plants grow. Plus, the profit potential from mutated event seeds has funded garden expansions I’d been putting off for weeks.
With only seven days to grab everything, make sure you’re maximizing every chipmunk feeding cycle and collecting those Acorn spawns religiously. And hey, if you manage to pull that rare 1% Acorn seed from a chest, I’m officially jealous. Drop your seed collection progress in the comments—I’d love to hear which ones you’re still hunting!
