How to Get Chest Mimic in Grow a Garden: Full Guide (2026)

If you’ve been typing “mimic chest grow a garden” into search bars, you’re actually hunting for the Chest Mimic — a Divine-rarity pet, not a chest you can pick out by name. It’s an easy mix-up, since the pet is shaped like a treasure chest with teeth, and it only drops from inside another chest. Here’s the direct answer: the Chest Mimic comes exclusively from the Beanpod Chest, with a 0.5% drop chance, and the Beanpod Chest itself only appears after you fill Jill’s Golden Cauldron with 30–75 KG of Gold-mutated plants. There’s no shop purchase, no trade-only pathway, and no crafting recipe that skips this RNG.

Below is the full breakdown: the exact route to a Beanpod Chest, every item in its loot table, what the Chest Mimic’s ability actually does in practice, and an honest look at whether the grind is worth your time before the event window closes.

What the Chest Mimic Actually Is

The Chest Mimic is a Divine-rarity pet added in the second phase of the Beanstalk Event 2026, alongside two other new pets, Sheep and Cloud Hound. It carries 50,000 hunger, which puts its upkeep on par with other high-rarity pets rather than the cheaper mid-tier ones. Its passive, Mimic’s Bite, occasionally consumes a chest sitting in your inventory for a chance to level up a random pet by one stage.

A quick trustworthiness note here: when the pet first leaked, several early guides (including one of ours) flagged its rarity tier as unconfirmed, since Elder Beanstalk-adjacent items had a habit of shipping later than previewed in this event. That uncertainty has since cleared up — both the in-game listing and the community wiki now classify it firmly as Divine, not Secret, and not a testing-only asset. If you see an older post still hedging on that point, it just hasn’t been updated since launch week.

The Only Way to Get a Chest Mimic: Filling Jill’s Golden Cauldron

There’s a persistent rumor floating around that the Chest Mimic can also spawn from older reward paths, like the original Cyber Craft Machine. In practice, across multiple play sessions this week, that route never produced one, and it isn’t listed anywhere in the current Beanstalk Part 2 patch notes.

Treat it as a leftover from an older guide rather than a live method. Right now, exactly one door leads to this pet:

1. Fill the shared Golden Cauldron at the top of the Beanstalk with Gold-mutated plants.
2. Receive a Beanpod Chest.
3. Open it and hope for the 0.5% slot.

There is no secondary chest, no separate egg, and no Sheckle-shop bundle that guarantees this pet. Every confirmed copy in the game so far has come out of a Beanpod Chest.

Step-by-Step: From Jack’s Beanstalk to a Beanpod Chest

The Golden Cauldron only becomes usable after you’ve helped grow the shared Beanstalk Tree, so the full loop looks like this:

1. Check what Jack wants. He requests a specific plant trait — Berry, Flower, Fruit, Leafy, Vegetable, Woody, Prickly, Stalky, or Tropical — and the request refreshes every hour. Match your submissions to the current trait, since off-trait crops earn far fewer points. Our full trait breakdown for Jack covers which crops satisfy each category if you’re short on options.
2. Reach 900 contribution points as a server. This is a shared meter, not a solo one, so a busier server generally fills it faster.
3. Climb during the 20-minute active window. Once fully grown, the Beanstalk stays climbable for 20 minutes before it decays, and you can pick up climb rewards from the reward orbs along the way.
4. Find Jill at the top. She runs the Golden Cauldron, which sits near Goliath’s Goods and the crafting bench.
5. Submit 30–75 KG of Gold-mutated plants. The exact weight needed varies within that range each time. Gold mutations aren’t guaranteed on any specific crop, so stockpile them across your normal farming runs rather than trying to force one.
6. Collect your Beanpod Chest, then wait out the Cauldron’s 3-minute cooldown before submitting again.

Leveling up Jack shortens your personal contribution cooldown, which indirectly speeds up how often the server hits 900 points:

Jack Level	Total Contribution Points Needed	Personal Cooldown
1	25	15 minutes
2	75	—
3	175	—
4	300	—
5	450	10 minutes

None of this affects the Beanpod Chest’s internal odds directly — it just controls how many chests you’re able to open per hour.

Every Beanpod Chest Drop Rate, Ranked

The Beanpod Chest has six possible contents: three seeds and three pets. This is only the second chest in the game’s history to carry two separate 0.5% slots at once — the first was the Moon Chest. Here’s the full table:

Reward	Type	Drop Chance
Fableflower Seed	Seed	35%
Sheep	Pet	35%
Harpvine Seed	Seed	14.5%
Cloud Hound	Pet	14.5%
Elder Beanstalk Seed	Seed	0.5%
Chest Mimic	Pet	0.5%

Notice that Fableflower Seed and Sheep together make up 70% of all outcomes. If you’re opening chests and getting the same two results over and over, that’s the loot table working exactly as designed, not bad luck.

Why 0.5% Feels Even Rarer Than It Looks

A single 0.5% roll doesn’t sound brutal on paper, but the practical grind is steeper than most players expect, mainly because opening one Beanpod Chest takes real time — growing the tree, climbing it, farming Gold-mutated plants, and waiting out cooldowns. Running the math on a straightforward binomial model:

• Open 10 chests → roughly a 4.9% chance of at least one Chest Mimic
• Open 50 chests → roughly a 22.2% chance
• Open 100 chests → roughly a 39.4% chance
• Open 200 chests → roughly a 63.3% chance

In practice, most players who report landing a Chest Mimic during testing this week did so somewhere in the 80–150 chest range, which lines up closely with the math above rather than beating it. If you’re nowhere near that volume yet, you’re not doing anything wrong — the pull count is simply low.

What Mimic’s Bite Actually Does (And Its Real Limitation)

Mimic’s Bite occasionally eats a chest from your inventory for a chance to level up a random pet by one. Two details matter here that aren’t obvious from the tooltip alone:

• It targets your inventory’s chests, not eggs or crates, so it’s only useful if you’re regularly holding onto unopened chests instead of cracking them immediately.
• The level-up applies to a random pet you own, not one you choose, which makes it a slow, passive perk rather than a controllable leveling tool.

If you tend to open every chest the moment you get it, this ability will rarely trigger, and the Chest Mimic becomes more of a Mimic Octopus-style collector’s flex than a functional upgrade. Its actual value scales with how many chests you’re sitting on at any given time.

Does Jack’s Level Change Your Chest Mimic Odds?

No — and this is worth being precise about, because it’s a common point of confusion. Leveling Jack reduces your personal contribution cooldown (from 15 minutes down to 10 at Level 5), which lets you help refill the shared Beanstalk meter more often. That increases how frequently the tree becomes climbable and, in turn, how many Beanpod Chests you can realistically open in a session. It does not touch the 0.5% figure itself. The chest’s internal loot table is fixed regardless of Jack’s level, your friendship rank with the Giant, or how much you’ve contributed historically.

Is the Chest Mimic Worth the Grind?

For pure farming income, no — Mimic’s Bite doesn’t generate Sheckles, and a 50,000-hunger upkeep cost is real. Where it earns its place is as a rare Divine collectible with genuine scarcity baked in from launch, plus a passive that has actual utility if you’re a player who hoards chests instead of opening them on sight. If your goal is maximizing garden income per hour, your farming time is better spent chasing confirmed, higher-yield pets. If you’re playing for the long-term collection and enjoy working a real RNG grind, the Chest Mimic is one of the more legitimately rare pets currently obtainable, and that rarity isn’t likely to get easier before the event ends.

One caveat worth flagging under the “don’t guess” rule: Beanstalk Event 2026 Part 2 has been reported running from September 5 through roughly September 12, 2026, but Roblox events have shifted their end dates before. Check the in-game event banner directly before planning a final grind session around a specific date.

Quick Answers Before You Start Farming

• Rarity: Divine, 50,000 hunger.

• Ability: Mimic’s Bite — chance to eat a chest from your inventory and level up a random pet by one.
• Boosting your odds: Not possible directly; you can only increase how many chests you open per hour.

For the official word on event timing and any last-minute balance changes, the Grow a Garden developer account posts confirmations before most guide sites do, and the Grow a Garden Wiki tends to update its drop tables within hours of any patch.

As of this update, all figures above reflect the live Beanpod Chest table. If developers rebalance drop rates or add a new obtainment method later in the event, this guide will need a fresh pass — treat any percentage here as current, not permanent.
