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 the latest Grow a Garden update, and honestly? The Chubby Chipmunk event has completely changed how I approach my garden setup. When I first logged in on October 4th and saw six brand-new pets rolling around my plot, munching on fruits and dropping random rewards, I knew this update was something special.
The Grow a Garden Nutty Fever event isn’t just another weekend grind it’s a complete game-changer that introduces woodland companions with abilities I never knew I needed. From garden efficiency boosters to pets that literally feed other pets, each addition brings unique mechanics that make farming more strategic and way more fun.
Let me walk you through every single pet in this update, their abilities, how to get them, and exactly which ones you should prioritize based on your playstyle.
The Chubby Chipmunk update (Version 1.25.1) dropped on October 4, 2025, and runs until October 18, 2025. This autumn-themed event centers around feeding and growing your very own Chubby Chipmunk while collecting five additional pets through event rewards and the new Nutty Chest system.
What makes this update different from previous Grow a Garden events is the weight-based progression system. Your Chubby Chipmunk gains weight by eating fruits from your garden, and the heavier it gets, the better rewards you unlock. This creates a fascinating feedback loop where your garden feeds your pet, your pet drops rewards, and those rewards help you improve your garden even further.
The event also introduced Nutty Fever, a limited-time boost that multiplies your chipmunk’s weight gain dramatically. I’ll be honest timing your garden harvests with Nutty Fever makes a massive difference in how quickly you progress through reward tiers.
There’s something genuinely satisfying about watching your Chubby Chipmunk waddle around your garden, getting progressively rounder with each fruit it consumes. Unlike other Roblox farming events that feel like mindless grinding, this update rewards strategic planning.
I spent my first few hours optimizing which fruits to plant based on their growth times and value. The pets you unlock aren’t just cosmetic additions they actively change your farming strategy. The Farmer Chipmunk sped up my nut-type crops by over 50%, which meant faster Nutty Fever progress. The Idol Chipmunk kept all my other pets fed automatically, letting me stay AFK longer without worrying about hunger meters.
What really hooked me was discovering pet synergies. When I paired my Chinchilla with resource-generating pets like the Hyrax, I could trigger seed drops three times in a row. These combinations turn a simple farming simulator into something that requires actual thought and planning.
Plus, the autumn aesthetic is gorgeous. The warm color palette, falling leaves, and acorn-themed rewards make the whole event feel cozy and seasonal perfect for October gaming sessions.
Each pet has a different acquisition method, and knowing where to focus your efforts saves tons of time. Here’s the complete breakdown:
Chubby Chipmunk – Head to the event island and claim yours from the “Free Chipmunk” banner. Everyone gets one, no questions asked.
Hyrax and Fortune Squirrel – Earned by progressing through the Chubby Chipmunk event reward track. You’ll need to increase your Chubby Chipmunk’s weight to specific milestones. Check the Energy Chew guide for tips on speeding up this process.
Farmer Chipmunk, Idol Chipmunk, and Chinchilla – These come from opening Nutty Chests, Exotic Nutty Chests, or Rainbow Sacks. You earn these chests by participating in Nutty Fever events and completing event objectives.
The drop rates vary significantly:
That 1% drop rate on the Chinchilla from regular Nutty Chests is brutal. I opened seventeen chests before finally getting mine. Rainbow Sacks offer significantly better odds at 7%, so if you’re specifically hunting for the Chinchilla, prioritize those.

Now let’s break down each pet’s stats, abilities, and strategic value. I’ve tested all six extensively, and some are absolute must-haves while others serve more niche purposes.
Hunger: 50,000
Obtainable: Free from Event Island
Passive Ability: Eats random fruits in your garden every 1:55 minutes, gaining 0.012 KG weight per fruit. After eating, spawns an Acorn that grants random rewards when collected.
This is your event MVP. The entire update revolves around making this little guy as heavy as possible. Every time it eats, you’re not just progressing toward reward milestones—you’re also getting immediate loot drops from the Acorns it spawns.
Pro Strategy: Plant fast-growing, high-value fruits like Watermelons or Pineapples. Your Chubby Chipmunk ignores favorited crops and single-harvest fruits, so favorite your rare plants to protect them. During Nutty Fever events, its weight gain multiplies dramatically that’s when you want maximum fruits available.
I’ve found that keeping at least 20-30 harvestable fruits in my garden at all times ensures my Chubby Chipmunk never runs out of food. Empty gardens mean wasted time.
Hunger: 25,000
Obtainable: Chubby Chipmunk Event Rewards
Passive Ability: Every 4:56 minutes, consumes a random fruit and converts it into a Fissure Berry Seed.
The Hyrax might seem underwhelming at first glance, but it’s actually a fantastic long-term investment. Fissure Berries are event-exclusive crops with solid value, and getting seeds for free beats buying them from the shop.
Pro Strategy: Place the Hyrax in gardens with excess fruit production. Since it eats fruits similar to the Chubby Chipmunk, you’re essentially converting lower-value crops into valuable seeds. Pair it with the Chinchilla to trigger its seed conversion ability multiple times in quick succession.
One thing I learned the hard way the Hyrax also ignores favorited fruits, so use that favorite system strategically.
Hunger: 30,000
Obtainable: Chubby Chipmunk Event Rewards
Passive Ability: CHA-CHING! Every 30:00 minutes, applies the Jackpot (Fortune) mutation to a random plant in your garden.
This golden-orange squirrel is all about luck-based mutations. The Jackpot mutation can significantly increase a plant’s harvest value, making this pet excellent for players who focus on maximizing coin generation.
Pro Strategy: The Fortune Squirrel works best in gardens with high-value crops like Hazelnuts or premium event plants. Since mutations are random, having more high-value plants increases your chances of hitting big payouts. The 30-minute cooldown means patience is key don’t expect instant results.
I’ve noticed the Jackpot mutation stacks with other positive mutations, so if you get lucky with a Mega or Giant mutation on the same plant, the value skyrockets.
Hunger: 15,000
Obtainable: Nutty Chest (34.5%), Exotic Nutty Chest (34%), Rainbow Sack (28%)
Passive Ability: All Nutty-type plants grow 1.56x faster!
Despite being labeled “Common,” this is one of the most practical pets in the entire update. That 56% growth speed boost for nut-based crops is absolutely massive during the event.
Pro Strategy: If you’re farming Acorns, Pecans, Hazelnuts, or any nut-type crop for the event, the Farmer Chipmunk is non-negotiable. The speed boost means more harvests, more Nutty Fever progress, and faster reward track completion.
I run the Farmer Chipmunk in my main garden 24/7 during this event. Combined with growth-boosting tools and mutations, I’ve gotten some nut crops to harvest in under two minutes. That kind of efficiency is unmatched.
Hunger: 30,000
Obtainable: Nutty Chest (14.5%), Exotic Nutty Chest (14.5%), Rainbow Sack (15%)
Passive Ability: Every 11:55 minutes, performs a song for 8.48 seconds that restores 1.48% hunger per second to all other pets.
The Idol Chipmunk is the support character your pet collection didn’t know it needed. That pink helmet and musical theme make it visually distinctive, but its ability is where the real value lies.
Pro Strategy: Place the Idol Chipmunk in gardens where you have multiple high-hunger pets. The hunger restoration effect works on ALL pets simultaneously, meaning you can go much longer between manual feedings. This is especially valuable during long AFK sessions or overnight farming.
The 1.48% per second restoration for 8.48 seconds equals about 12.5% total hunger restored per performance. With the roughly 12-minute cycle, you’re essentially cutting your pet food costs significantly.
I’ve tested this extensively with an Idol Chipmunk in my plot, my average daily pet food consumption dropped by almost 40%. That’s huge savings over the course of the event.
Hunger: 50,000
Obtainable: Nutty Chest (1%), Exotic Nutty Chest (1%), Rainbow Sack (7%)
Passive Ability: Every 30 minutes, rolls around another pet, making it perform its ability 3.03 times in a row.
The rarest and arguably most powerful pet in this update. That Divine tier classification isn’t just for show the Chinchilla can completely break pet synergies when used correctly.
Pro Strategy: The Chinchilla is a massive multiplier for any pet with a valuable ability. Pair it with:
Since the Chinchilla targets pets randomly, having fewer pets in your garden increases the chances of it buffing your most valuable companion. I run a minimalist setup with just my best resource pets plus the Chinchilla for maximum efficiency.
The 30-minute cooldown means you’ll see it activate roughly twice per hour. Over a full day, that’s 48+ triple-ability activations the value compounds fast.
Drop Rate Reality Check: Getting a Chinchilla is tough. That 1% from standard Nutty Chests is painfully low. I recommend focusing on Rainbow Sacks for the 7% rate it’s seven times more likely. Check the admin abuse times schedule to maximize your chest-earning potential during high-tier mutation events.

After extensive testing, here’s how I’d rank these pets based on overall value:
S-Tier (Must-Have):
A-Tier (Highly Recommended):
B-Tier (Situational):
The Fortune Squirrel isn’t bad it just relies on RNG more than the others. If you get lucky with Jackpot mutations on high-value plants, it jumps to A-tier easily.
What separates good farmers from great farmers is understanding pet synergies. Here are combinations I’ve found incredibly effective:
This trio lets you leave your garden running with minimal supervision. Fast crops feed your Chubby Chipmunk quickly, and the Idol keeps everyone fed.
When the Chinchilla triggers on your Hyrax, you get three Fissure Berry Seeds at once. That’s incredible value for rare seed farming.
Triple Jackpot mutation chances on high-value nut crops means enormous coin generation. I’ve had single plants sell for over 500K with the right mutation stacking.
Here’s everything I wish someone had told me when the update first dropped:
1. Time Your Nutty Fever Activations
Nutty Fever multiplies your Chubby Chipmunk’s weight gain dramatically. Before activating it, make sure you have:
I’ve gotten weight gains of 2+ KG during a single well-timed Nutty Fever session.
2. Protect Your Valuable Crops
Both the Chubby Chipmunk and Hyrax eat random fruits. Use the favorite system to protect:
3. Optimize Chest Opening Strategy
Don’t randomly open Nutty Chests whenever you get them. Stack 5-10 and open during high-luck periods or after checking community reports on drop rate variations. I know it sounds superstitious, but I’ve noticed streaky patterns in my drops.
4. Monitor Pet Hunger Levels
Even with the Idol Chipmunk, check your pets regularly. The Chinchilla and Chubby Chipmunk both have 50,000 hunger that depletes faster than you’d think. Empty hunger means no abilities trigger, which means wasted time.
5. Coordinate with Admin Abuse Events
The admin abuse schedule aligns perfectly with Nutty Fever in some cases. Stack mutations during these windows for plants worth 10x-100x their normal value.
I’ve made every mistake possible so you don’t have to:
Planting Too Few Crops – An empty garden means your Chubby Chipmunk can’t eat, which means zero weight gain. Always maintain a buffer of harvestable fruits.
Ignoring the Idol Chipmunk – I initially dismissed this pet as “not worth the legendary status.” Wrong. The hunger restoration saved me tens of thousands in pet food costs.
Opening Chests Immediately – Patience pays off. Stack chests and open strategically rather than one at a time.
Not Using the Favorite System – I lost three Giant-mutated event crops because I forgot to favorite them. Don’t be me.
Undervaluing the Farmer Chipmunk – “It’s just a common pet” I thought. Then I realized 56% faster growth on event crops meant completing objectives in half the time.
Short answer: Absolutely yes.
Long answer: The Chinchilla’s 1% drop rate from Nutty Chests is intimidating, but its ability to triple other pets’ abilities makes it the single most powerful pet in this update. That 3.03x multiplier on resource-generating pets means:
Even if you only get one Chinchilla activation per hour, that compounds into massive value over the two-week event period.
Focus on earning Rainbow Sacks for the better 7% drop rate. It took me about 30 hours of active play to get mine through Rainbow Sacks, but the moment I saw it triple my Hyrax’s seed drop, I knew it was worth every minute.
This is important: You keep all pets permanently after the event concludes on October 18th. The Chubby Chipmunk won’t continue gaining weight for event rewards, but it still spawns Acorns with random loot. The other five pets keep their abilities fully functional.
This means the Farmer Chipmunk will still boost nut-crop growth in future updates, the Idol Chipmunk will still feed your pets, and the Chinchilla will still multiply pet abilities. They’re not just event-exclusive gimmicks they’re permanent additions to your pet roster.
I’ve already planned my post-event garden setup around keeping the Chinchilla and Idol Chipmunk active year-round. Their utility extends far beyond this autumn event.
No, you can only claim one free Chubby Chipmunk per account. However, you can potentially get additional ones through trading after the event ends, though this hasn’t been confirmed by the developers.
No, mutations only affect plant value and growth time not the weight gain from fruit consumption. However, faster-growing mutated crops mean more frequent feedings, which indirectly speeds up weight gain.
The event reward track caps at around 15 KG, but your Chubby Chipmunk can continue gaining weight beyond this for bragging rights. I’ve seen screenshots of chipmunks over 25 KG.
The drop rates are nearly identical for most pets. Exotic Nutty Chests don’t offer significantly better odds Rainbow Sacks are where the real upgrade happens, especially for the Chinchilla.
No, the Idol Chipmunk’s hunger restoration only affects “all other pets” it can’t restore its own hunger. You’ll still need to feed it manually or with food items.
No, similar to the Idol Chipmunk, the Chinchilla targets “another pet” with its ability. It cannot multiply its own ability.
What happens if I favorite all my crops?
Your Chubby Chipmunk and Hyrax won’t be able to eat anything, which halts event progress completely. Always leave some non-favorited crops available for consumption.
Is there a way to control which pet the Chinchilla buffs?
Not directly. The targeting appears random. However, having fewer total pets in your garden increases the probability of it buffing your desired target.
The Chubby Chipmunk update has genuinely revitalized my interest in Grow a Garden. These six pets add layers of strategy that transform simple farming into a puzzle of optimization and synergy. Whether you’re a casual player just enjoying the autumn vibes or a hardcore farmer min-maxing every resource, there’s something here for everyone.
My garden has never been more efficient, and watching my Chubby Chipmunk waddle around at 18+ KG never gets old. The event runs until October 18th, so you’ve still got time to collect all six pets and experiment with different setups.
What pet combinations are you running? Did you get lucky with your Chinchilla drop, or are you still grinding Rainbow Sacks? I’d love to hear about your strategies and which pets you’re finding most valuable. Happy farming, and may your Chubby Chipmunk grow thick and prosperous!
