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 playing Grow a Garden since the early days, and let me tell you the Chubby Chipmunk event that dropped on October 4th is honestly one of the most addictive updates I’ve experienced in any Roblox game. There’s something oddly satisfying about watching this tiny chipmunk transform into an absolute unit while unlocking exclusive rewards along the way.
If you’re like me and want to maximize your Chubby Chipmunk’s weight quickly to snag those premium rewards before the event ends on October 11th, you’ve landed in the right place. I’ve spent the last 48 hours testing every method, and I’m sharing everything that actually works—no fluff, just results.
Before I dive into the weight-gain strategies, let me give you some context about what makes this event so special. The Chubby Chipmunk Update (v1.25.1) introduces a completely new mechanic to Grow a Garden: weight-based progression. This isn’t like previous events where you just collect items or complete tasks. Your Chubby Chipmunk literally grows heavier as you feed it, and that weight unlocks increasingly valuable rewards.
The event runs from October 4 to October 11, 2025, giving you exactly one week to fatten up your chipmunk companion. Here’s what makes it groundbreaking: every kilogram your chipmunk gains pushes you further along a reward track that includes new seeds, pets, furniture, and even the coveted Fortune Squirrel and Pecan (a divine-tier plant).
The first thing you need to do is claim your free Chubby Chipmunk pet. Head to the event area in the center of the lobby and look for the banner on the right side of the Nuts NPC. Click it, and boom—you’ve got your chipmunk. No grinding required for this step, which is refreshing.
Honestly? This event hits different. Most Grow a Garden events feel like standard grinds where you’re just harvesting crops and opening chests. But with the Chubby Chipmunk, there’s this weird emotional investment that happens. You’re literally raising a pet and watching it grow before your eyes.
What hooked me immediately was the passive progression. Even when I’m not actively playing, my chipmunk is munching away at fruits in my garden, slowly gaining weight. Then I’ll log back in and see it’s grown visibly larger, and there’s an acorn waiting for me to collect. It’s like having a Tamagotchi in Roblox, except this one actually rewards you with game-changing items.
The Nutty Fever community event aspect is also genius. Everyone’s contributing plants to the Nuts NPC, and when the server hits 1500 points collectively, chaos erupts in the best way possible. Your chipmunk goes into overdrive, eating every 30 seconds instead of every 5 minutes. I’ve had sessions where my chipmunk gained over 0.5 kg in just 20 minutes of active Nutty Fever gameplay.
Plus, the rewards are actually worth pursuing. That Fortune Squirrel at 47 kg? It applies the Jackpot mutation to your plants, which can completely change your farming economy. And Pecan at 50 kg is one of the rarest divine plants ever added to the game.
Alright, let’s get into the actual strategies. I’ve ranked these by effectiveness based on my testing, and I’ll explain exactly how to execute each method.
This is your foundation. The Chubby Chipmunk has a passive ability that makes it automatically eat a random fruit from your garden every 4 minutes and 58 seconds. Each automatic feeding session adds approximately 0.009 kg to its weight.
Here’s how to optimize this:
First, fill your garden with multi-harvest fruits. The chipmunk ignores single-harvest plants and favorited items, so you want crops that regenerate. I personally use Strawberries, Blueberries, and Tomatoes because they regrow quickly and don’t require constant replanting.
Second, don’t favorite your fruit trees if you want maximum feeding frequency. I made this mistake initially—I had favorited all my rare fruits, and my chipmunk was barely eating because there weren’t enough available options.
Third, stay logged in when possible. The automatic feeding only triggers when you’re in the game. I know not everyone can AFK farm, but if you can leave your game running while doing homework or watching videos, you’re getting free weight gains every 5 minutes.
The math here is simple: if you’re logged in for 1 hour, your chipmunk will eat approximately 12 times, gaining around 0.108 kg. Over 8 hours of gameplay (or AFK time), that’s roughly 0.86 kg without you doing anything active.
This is where things get interesting. When you manually feed your Chubby Chipmunk, there’s a 15.10% base chance it gains 0.01 kg. But here’s the game-changer: every mutation on the fruit increases that probability by 3.29%.
I tested this extensively, and the results speak for themselves. A regular fruit gives you about a 1-in-7 chance of weight gain. But a fruit with 3 mutations (Mega, Giant, Fortune) gives you approximately a 25% chance—basically 1-in-4. With 5+ mutations, you’re looking at over 30% success rates.
Here’s my feeding strategy that actually works:
Start by growing Prismatic-mutated crops. These are fruits that have accumulated multiple mutations through natural RNG or by using mutation beans. My go-to crops for this are Watermelons and Pumpkins because they’re larger plants that tend to collect mutations more easily.
When you have a heavily mutated fruit ready, feed it directly to your chipmunk. Don’t let it auto-eat these premium fruits—manually clicking the chipmunk and selecting the mutated fruit ensures you’re using your best resources intentionally.
I keep a dedicated mutation garden separate from my main farming area. This garden has about 20-25 plots where I’m specifically trying to stack mutations on fruits. Every time I get a fruit with 4+ mutations, it goes straight to the chipmunk.
In my testing, I was able to gain approximately 0.15-0.20 kg per hour using aggressive manual feeding with mutated fruits. That’s nearly double the passive rate.
The Nutty Fever event is by far the fastest weight-gain method, but it requires active participation from you and your server. When Nutty Fever is active, your chipmunk’s ability cooldown drops from 5 minutes to 30 seconds. That’s a 10x increase in feeding frequency.
Here’s how to maximize Nutty Fever:
First, understand how to trigger it. The Nuts NPC at the center of the event area has a progress bar above its head. You and other players submit harvested plants to fill this bar. Once it reaches 1500 points, Nutty Fever activates for approximately 5 minutes.
Different plants give different point values. From my testing:
I figured out that the most efficient strategy is to farm Nut-type plants specifically for submission. If you have the Farmer Chipmunk pet (35.5% chance from Nutty Chests), these plants grow 1.56x faster, making them even more efficient.
During Nutty Fever, your chipmunk will eat roughly 10 times in 5 minutes. Even with the reduced weight gain per feeding (about 0.005 kg each during Nutty Fever), that’s still 0.05 kg in just 5 minutes. If you can trigger Nutty Fever 4-5 times per hour, you’re gaining 0.20-0.25 kg hourly.
Pro tip: Join populated servers. More players = faster Nutty Fever triggers. I specifically look for servers with 15+ active players in the event area.
This method is controversial because it requires Mutation Beans (Mega or Giant), which aren’t free. However, if you have these resources available or you’re willing to invest Robux, this creates a permanent boost to your chipmunk’s weight-gain rate.
Mega Mutation increases your pet’s hunger rate, which means it eats more frequently during automatic feeding. With Mega mutation applied, my chipmunk’s feeding interval dropped from 4:58 to approximately 4:15. That’s an extra feeding session every 30 minutes, which adds up significantly over the week-long event.
Giant Mutation has a similar effect but also increases the pet’s physical size dramatically, which looks awesome when you’re showing off your garden to friends.
The downside? Your chipmunk will require more total food to keep it from getting hungry. I had to expand my fruit garden by about 30% to keep up with the increased consumption. But if your goal is maximum weight by October 11th, this trade-off is absolutely worth it.
I applied both Mega and Giant mutations to my chipmunk on Day 2, and by Day 3, it was noticeably heavier than my friends’ chipmunks who were using only passive strategies.
Every time your Chubby Chipmunk eats a fruit (both automatic and manual), there’s a chance it spawns an Acorn somewhere random in your garden. These acorns contain random rewards, including Energy Chews.
Energy Chews are game-changing because they instantly refresh your chipmunk’s ability cooldown. Instead of waiting 5 minutes for the next automatic feeding, you can trigger it immediately.
I developed a routine where I collect acorns the moment they spawn and save Energy Chews specifically for Nutty Fever sessions. During Nutty Fever, when the cooldown is already reduced to 30 seconds, using an Energy Chew essentially gives you an instant feeding. In a single Nutty Fever event, I can usually use 2-3 Energy Chews for bonus feedings.
Make sure you’re checking all corners of your garden regularly. Acorns can spawn in weird places, sometimes behind decorations or in hard-to-see spots. I zoom out my camera fully and do a quick scan every few minutes.
Understanding what you’re working toward is crucial for motivation. Here’s the complete reward track based on your chipmunk’s weight:
Early Milestones (0-10 kg):
Mid-Tier Rewards (10-30 kg):
Premium Rewards (30-50+ kg):
The Fortune Squirrel is probably the most valuable reward because its Jackpot (Fortune) mutation significantly increases the value of your crops. In testing, Fortune mutation can boost a plant’s sell value by 3-5x, which completely changes your coin economy.
Pecan at 50 kg is the ultimate flex. As of my writing this, fewer than 5% of players have reached this milestone. It’s a divine plant, which means it has incredibly high base stats and can be mutated into insane profit generators.
After grinding this event for days, I’ve discovered some optimization tricks that aren’t obvious:
Time Your Play Sessions Around Nutty Fever
Don’t just play randomly throughout the day. Wait until Nutty Fever is close to triggering (check the NPC’s progress bar), then log in and commit to 15-20 minutes of active playing. You’ll gain way more weight per hour of actual gameplay.
Create a Dedicated Feeding Garden
I mentioned this earlier, but it deserves its own point. Section off 20-30 plots specifically for fruits you’re growing to feed your chipmunk. Fill this area with fast-growing, multi-harvest crops. Separate this from your profit gardens so you’re not accidentally eating income sources.
Use the Farmer Chipmunk Pet if You Have It
This pet is a 35.5% drop from Nutty Chests, so you might get lucky early. It makes all nut-type plants grow 1.56x faster with no range limit. That means faster Nutty Fever triggers AND faster feeding resources for your chipmunk.
Don’t Sleep on the Idol Chipmunk
While everyone’s chasing the Fortune Squirrel, the Idol Chipmunk (14.5% from Nutty Chest) is secretly amazing. It performs a song every 11 minutes that restores 1.48% hunger per second to all pets for about 8 seconds. This keeps your Chubby Chipmunk from getting hungry between feedings, ensuring it’s always ready to eat.
Stock Up Before the Event Ends
We’re already halfway through the event (it ends October 11th). If you haven’t hit your target weight yet, consider using Robux to buy Mutation Beans or spending your saved-up game currency on resources. This is a limited-time event—after October 11th, you can’t increase the weight anymore.
Join the Grow a Garden Discord
The community often shares active Nutty Fever servers. Players will post server codes when Nutty Fever is about to trigger, letting you hop in for quick weight gains. I’ve gained an extra 2-3 kg just from server-hopping during peak times.
Common Mistakes to Avoid:
❌ Favoriting all your fruits – Your chipmunk can’t eat favorited items, reducing feeding opportunities
❌ Ignoring Nutty Fever – This is 10x faster than passive feeding; prioritize active play during these windows
❌ Feeding unmutated fruits manually – Save your manual feeding actions for highly mutated crops; let auto-feeding handle basic fruits
❌ Not collecting acorns immediately – Acorns can despawn if you wait too long; collect them as soon as they appear
❌ Focusing only on one method – Combine passive feeding, manual feeding, and Nutty Fever for optimal results
While there aren’t specific Chubby Chipmunk event codes yet, here are active Grow a Garden codes that can help you get resources for the event:
I’ll be honest—most of the progression in this event is skill and time-based rather than code-dependent. But any free resources help, especially Mutation Beans if they release codes for those.
The update introduces six new pets, each with unique abilities that complement the event:
Chubby Chipmunk (Free) – The star pet; gains weight when eating fruits and spawns acorns
Farmer Chipmunk (35.5% Nutty Chest) – Grows all nut-type plants 1.56x faster across your entire garden
Idol Chipmunk (14.5% Nutty Chest) – Sings every 11 minutes to restore hunger to all pets
Chinchilla (1% Divine) – Every 30 minutes, triggers another pet’s ability three times consecutively (absolutely broken)
Hyrax (Common) – Occasionally eats a fruit and spits out a Fissure Berry Seed
Fortune Squirrel (47 kg reward) – Occasionally applies Jackpot (Fortune) mutation to random plants
The Chinchilla is probably the most game-breaking pet ever added to Grow a Garden. Imagine tripling the effect of powerful pets like the Raccoon or French Fry Ferret. It’s a 1% drop rate, so incredibly rare, but if you get it, your entire farming strategy changes.
With optimal play (active Nutty Fever participation + manual feeding with mutated fruits), you can gain about 2–3 kg per day. Casual play averages 1–1.5 kg daily. I personally managed 2.8 kg in a single 8-hour session by combining both strategies.
No! Once gained, weight is permanent. The only downside to not feeding is that your chipmunk won’t trigger its passive eating ability when it’s hungry—so keeping fruits in your garden helps keep progress steady.
The last reward milestone is at 50 kg (Pecan seed), but there’s no hard cap. Some players are pushing well past 50 kg just to see how massive their chipmunk can grow. Mine is currently 38.7 kg and still climbing.
No. Each player gets one free chipmunk from the event. Multiples aren’t obtainable. After the event, they may become tradeable or egg-available in the future, but that’s unconfirmed.
You keep it permanently. Its final weight is locked in, and any milestone rewards stay claimed. However, you won’t be able to increase its weight further once the event ends on October 11.
No. The event is 100% free-to-play friendly. Robux can speed things up (Mutation Beans, Exotic Nutty Chests), but aren’t required to reach major milestones.
For passive feeding, focus on multi-harvest fruits like Strawberries, Blueberries, Tomatoes, and Watermelons. For manual feeding, prioritize mutated crops (Pumpkins and Watermelons are excellent). Stack mutations before feeding for maximum weight gain.
Yes! Nutty Fever works in both public and private servers. Many players actually prefer private servers since they can time submissions perfectly without competition.
This Chubby Chipmunk event honestly caught me off guard with how engaging it is. I thought I’d casually play for a couple days and move on, but here I am on Day 3, strategically planning my feeding schedules and mutation gardens like I’m running a competitive farming operation.
What I love most is that every player can succeed with this event regardless of how much time they have. If you can only play 30 minutes daily, focus on manual feeding with your best mutated fruits during Nutty Fever windows. If you have more time, combine all the methods I’ve outlined for maximum efficiency.
We’ve got until October 11th to push our chipmunks to their absolute limits. My current goal is hitting 50 kg for that Pecan reward, and I’m on track to make it happen. If you started late, don’t stress—even reaching the 35-47 kg range gets you incredibly valuable rewards.
Drop a comment below with your current chipmunk weight, and let me know if you’ve discovered any tricks I missed! This community is constantly finding new optimization strategies, and I’d love to hear what’s working for you. Happy farming, and may your chipmunk grow gloriously chubby! 🐿️🌰
