Grow a Garden Harvest Moon Part 4 Is LIVE: The Moon Reward Track Math (252 Points to Finish, 6 Days Left), Cornling at Stage 12, Maize Stalk (Mythical) at 13, and Eclipse Berry (Prismatic) at 20 — August 23, 2026

Last Verified: August 23, 2026. Every rarity, stage cost, points total, quest refresh cadence, Robux skip price, Sheckle restart cost and code below is pulled directly from the official Grow a Garden Fandom wiki via the MediaWiki API this morning — the Harvest Moon Event page (Moon Rewards quest tables, 20-stage reward track, restart cost), the Cornling page, the Maize Stalk page, the Eclipse Berry page, the Corn page (for the Cornling synergy math), and the Codes page. Cornling proc rate, Corn Synergy per-plant scaling factor, sell values for Maize Stalk and Eclipse Berry, and quest-skip behaviour are still not on the wiki — every one of those is flagged as unknown inline. No invented numbers.

Harvest Moon Part 4 went live on August 22, 2026 and the wiki filled in the mechanics overnight. The centrepiece is the Moon Reward Track: 20 stages, 252 cumulative points to clear, and the three headline Part 4 items sit on the track at Stages 12, 13, and 20. The preview from Wednesday had the release date and the Cornling passive right, but two things it did not: Maize Stalk is not Divine, it is Mythical, and Eclipse Berry is not Divine either — it is Prismatic, the highest crop rarity in the game. That reshuffles the ceiling.

The other thing the preview could not have known: how you actually earn these three. There is no crafting recipe. There is no Moon Coin buy-outright. The path is the Moon Rewards quest ladder — and with the event closing on August 29, the math on whether Eclipse Berry is reachable at all without spending Robux is not close.

TL;DR — What Part 4 Actually Shipped

• Cornling — Legendary pet, 25,000 hunger, Corn Synergy passive. Path: Moon Reward Track Stage 12. Cumulative points needed from empty track: 78.
• Maize Stalk Seed — Mythical multi-harvest crop. Path: Reward Track Stage 13. Cumulative points: 92. (Preview called this Divine; wiki now says Mythical.)
• Eclipse Berry Seed — Prismatic multi-harvest crop, the highest crop rarity in the game. Path: Reward Track Stage 20. Cumulative points: 252. (Preview called this Divine too; wiki now says Prismatic.)
• Reward Track quests: 3 active at a time, refresh every 4 hours, 1 point each. That is 18 points per day of perfect grinding.
• Skip a quest for 89 Robux; restart the track after clearing it for 10,000,000,000 Sheckles or 149 Robux.
• Event ends August 29. From today (August 23) that is a maximum of ~108 free points even if you never miss a refresh. Cornling and Maize Stalk are inside that window. Eclipse Berry is not.
• Active GAG codes re-verified against the wiki this morning: torigate, BEANORLEAVE10, RDCAward. LUNARGLOW10 remains Expired. No new launch code.

Preview Corrections — Tiers Moved

Two things worth stamping at the top because the Wednesday preview said both crops were Divine and the wiki now says otherwise. Nothing was wrong on Wednesday — the crop pages both showed a “Divine” icon on the pre-release stub. Both pages were re-edited on the 22nd once the update actually pushed:

• Maize Stalk now shows the Mythical tier icon on the wiki. Still multi-harvest. Still a Night-type / Stalky-type crop like Corn is.
• Eclipse Berry now shows the Prismatic tier icon. Multi-harvest. Tagged as Berry, Leafy, Magical, Night, Sour, and Woody — the widest category tag on a single Grow a Garden crop I have ever counted.

Prismatic sits above Divine in the crop rarity ladder (Common → Uncommon → Rare → Legendary → Mythical → Divine → Prismatic). That means Eclipse Berry is not just “the second Divine crop of Part 4” — it is the ceiling of the whole event. Whether the per-fruit sell value actually beats the current Divine ceiling is a separate question; sell values for both new crops are still TBA on the wiki as of this morning, so any specific Sheckle number circulating on TikTok today is invented.

How the Moon Reward Track Works

Straight from the wiki’s Moon Rewards section on the Harvest Moon Event page:

• The track has 20 stages. Each stage is unlocked by accumulating points.
• Points come from quests. There are 3 active quests at a time, and they refresh every 4 hours. Each cleared quest is worth 1 point.
• Quests roll from three difficulty pools — Easy, Medium, Hard — and all three tiers pay the same 1 point. Point rate is the same whether you draw “Harvest 3 Watermelons” or “Harvest 12 Watermelons.”
• You can skip a quest for 89 Robux. The wiki does not spell out whether the skip credits the point or just rerolls the quest, so treat the number as the price of getting past a quest you cannot or will not do, not as a guaranteed 1-point buy.
• Once you clear the full 20 stages, you can restart the track for 10,000,000,000 Sheckles or 149 Robux. That is a serious ten-billion — not a typo.

Two things worth calling out because they matter for planning tonight:

First, on the 4-hour refresh cadence: a perfect grind day is six refreshes × three quests = 18 points per day. That is the ceiling with zero Robux spend. Miss a refresh window — sleep, work, a quest that expires before you can finish it — and your daily rate drops fast.

Second, on the quest pool: the Hard pool includes lines like “Craft 1 Harvest Golem” and “Craft 1 Harvest Melon Seed.” If you have not built the Part 3 craft base (Harvest Golem alone needs a Moon Egg, a Mythical Egg, a Burning Bud, a Romanesco, and 70 Moon Coins per the Part 3 recipe breakdown), you can and should skip Hard rolls that ask for craft objectives you cannot fulfil rather than let them tick down. That is the correct use of the 89 Robux skip: get an impossible objective off the board, not to substitute for grinding.

The Full 20-Stage Reward Table

Every row below is straight from the wiki’s Moon Rewards table. Points are the number required to unlock that stage — they are not cumulative on the wiki, so the cumulative column is added here.

The shape of the cost curve is the story. Stages 1–12 each want as many points as the stage number. Stage 13 jumps to 14 — the first break from that pattern. Stage 18 jumps to 25 (a +3 gap over stage 17). Stage 20 costs 31 points on its own. The last four stages alone cost 112 points, which is more than the entire climb to Cornling at Stage 12.

The 6-Day Points Math

Event ends August 29. Post-published August 23. The counting question is: how many free points can a grinder starting today realistically clear?

Perfect ceiling: 18 points per day × 6 remaining days = 108 free points. If you started fresh today and never missed a 4-hour refresh, that is exactly enough to reach the end of Stage 14 (108 cumulative). That means:

• Cornling (Stage 12, 78 pts) — comfortably in reach. Any day-1 starter who does most refreshes gets Cornling on their farm.
• Maize Stalk Seed (Stage 13, 92 pts) — in reach with steady play. Requires roughly 5 out of the 6 days at near-perfect refresh cadence.
• Eclipse Berry Seed (Stage 20, 252 pts) — not reachable from a fresh start without spending Robux. Even the 108-point ceiling leaves 144 points short. If a quest skip does credit a point, that is roughly 144 × 89 = 12,816 Robux to buy the rest. If the skip only rerolls (as the wiki does not confirm either way), the number gets larger, because you are still short on quest opportunities.

Two important caveats on that math. First, if you have been running the Moon Rewards quests since Part 1 opened on August 1, the Reward Track has been earning points the whole time — check your track and your cumulative sits somewhere above zero already. The rewards at Stages 12, 13, and 20 are new (added August 22), but the track structure itself has been on the event page prior. Second: the ceiling above assumes you never lose an available quest to a refresh. Missing even three refreshes over six days — sleeping through one, being at work for another, sitting on an impossible Hard craft objective for a third — drops the ceiling by 9 free points and pushes the Maize Stalk stage from “comfortable” to “need every remaining refresh clean.”

Cornling (Stage 12) — Corn Synergy, Live Now

Cornling is the Legendary pet payout at Stage 12. Straight from the Cornling wiki page as of this morning:

• Rarity: Legendary.
• Hunger: 25,000. Middle-of-the-road for a Legendary — well above Wheat Crow’s 1,500 but nowhere near the 275,000 ceiling Harvest Golem introduced in Part 3.
• Obtainment: Reach Stage 12 of the Moon Reward Track.
• Passive — Corn Synergy: “Occasionally transfers all mutations on a fruit to a fruit with no mutation. There is a chance that each mutation stays on the original fruit for every Corn planted in the player’s garden.”

The passive is the pet. Read the two clauses separately:

1. “Occasionally transfers all mutations on a fruit to a fruit with no mutation.” On a proc, Cornling picks a fruit that already has mutations and moves the whole stack onto a plain fruit somewhere else in your garden. That is the base effect — on a zero-Corn farm, it is net-neutral: the donor loses its stack, the recipient gains it.
2. “There is a chance that each mutation stays on the original fruit for every Corn planted in the player’s garden.” Per Corn plant, the odds a given mutation stays put on the donor go up. With enough Corn, a proc can leave the donor mostly intact and hand a copy of its stack to a plain fruit — net gain in mutated fruits per proc.

Practically, that puts Cornling → Corn as loud a synergy telegraph as this game has ever put on a pet page. Corn is cheap and available right now: multi-harvest Rare, 16% stock chance in the base Seed Shop, 1,300 Sheckles per seed (or 135 Robux, or 135 Trade Tokens). If you want to actually run the synergy, buy Corn seed every restock between now and Cornling drop, and plant them out.

Two numbers the wiki still does not commit to, and no honest guide can invent: the base proc rate, and the per-Corn scaling factor. Those will only be visible once players log real data with Cornling in the field. Ignore any specific “proc every 30 seconds” or “each Corn adds 5%” number floating today — nobody has the sample size yet.

Against Moonbeam — the mutation the whole event is built around, worth 15× per the Crop Mutations wiki page and 300× stacked with Gold — that duplicator effect is a mechanic the game has never given players before. Copying a fat Moonbeam stack onto a plain Maize Stalk or Eclipse Berry while the donor keeps most of its own stack is the theoretical endgame loop of the whole event.

Maize Stalk Seed (Stage 13) — The Mythical Payout

From the Maize Stalk wiki page:

• Rarity: Mythical (previously flagged Divine on the pre-release stub — corrected on the 22nd).
• Multi-harvest: Yes. Confirmed.
• Categories: Night, Prickly, Stalky. Same Stalky bucket as Corn.
• Obtainment: Reach Stage 13 of the Moon Reward Track. There is no seed shop listing.
• Sell value / seed price: Still TBA.

Two things worth flagging. First, Maize is the botanical name for Corn. Pairing a Cornling pet with a Maize Stalk crop in the same drop and sticking Maize into the Stalky category are both intentional design signals — historical precedent from the last three events says Maize Stalk will very likely count as a “Corn” plant for Cornling’s per-Corn scaling. Not wiki-confirmed on the Cornling page, but the crop-type overlap and the naming are unusually direct. Second, Mythical is one full tier below Divine, so the raw per-fruit sell value is likely lower than the Divine ceiling crops from Part 3 (Harvest Melon, Emberpear); the value case for Maize Stalk is Corn Synergy pairing, not raw yield.

Eclipse Berry Seed (Stage 20) — The Prismatic Wall

From the Eclipse Berry wiki page:

• Rarity: Prismatic. Highest crop rarity in the game.
• Multi-harvest: Yes.
• Categories: Berry, Leafy, Magical, Night, Sour, Woody — six tags. That is the widest single-crop tag set I have seen in the game and means Eclipse Berry inherits every crop-type item bonus in play.
• Obtainment: Reach Stage 20 of the Moon Reward Track.
• Sell value: TBA.

The Prismatic tier is the reason Eclipse Berry is the real ceiling of the whole Harvest Moon event, not Harvest Melon or Emberpear from Part 3. Prismatic crops have historically been the highest per-fruit Sheckle payouts in the game, and pairing a Prismatic base with the Moonbeam 15× multiplier — and then stacking Gold on top for the 300× case — is where the endgame yield ceiling sits. Six category tags means every “boost this crop type” item you own works on it, which is a hidden second-order boost most crops do not get.

The catch is the one already covered in the 6-day math section: at 252 cumulative points from a cold start, Eclipse Berry is not reachable free in the remaining window. Anyone who wants it either already has a substantial points bank from playing since August 1, or is going to buy skips. There is not a third path.

The 6-Day Priority Ladder

What to actually do between now and August 29, in order:

1. Check your existing Reward Track progress. Before anything else. If Part 1–3 grinding has already pushed you past Stage 12, Cornling might be one refresh away. If you are cold-starting, you are at zero and the ceiling is Stage 13 or 14 free.
2. Set the 4-hour alarm. Every missed refresh is 3 points off your maximum. Six days at 18 points/day is razor-thin for Maize Stalk if you drop refreshes.
3. Skip Hard-tier craft objectives you cannot fulfil. If a quest asks for a Harvest Golem craft and you do not have the ingredients, the 89 Robux skip is worth it to free the slot — that is the intended use.
4. Buy Corn every base Seed Shop restock. 1,300 Sheckles per Corn seed at 16% stock chance. Get as many as you can plant. Every Corn in your garden by the time Cornling hits Stage 12 for you scales Corn Synergy up.
5. Do not chase Eclipse Berry with Robux unless you actually value Prismatic-tier collection. 12,000 Robux+ to buy your way past a 144-point gap (assuming skips even credit a point) is a real number, and Eclipse Berry’s raw sell value is still TBA. If it turns out to be modestly above Divine, that is not a hoard-of-Robux buy. If it turns out to be much larger, revisit next week — but wait for actual field data before spending.
6. Bank Moon Chests and Moon Eggs from the mid-track rewards (Stages 4, 6, 8, 10, 14, 15, 19). Those are the compounding rewards even if you never reach Eclipse Berry — each Moon Egg has been the source of most of the event’s mid-tier pets, and Moon Chests carry the Season 7 seed packs into the post-event.

FAQ

How do I get Cornling in Grow a Garden?

Reach Stage 12 of the Moon Reward Track. That is 78 cumulative points, earned from completing Moon Rewards quests at 1 point each. Quests refresh every 4 hours in sets of 3. There is no crafting recipe and no Moon Coin buy.

Is Maize Stalk a Divine crop?

No. The pre-release stub showed a Divine icon, but the wiki was updated on August 22 when Part 4 pushed — Maize Stalk is Mythical, one tier below Divine. It is still multi-harvest, and it is still the Stage 13 payout.

Is Eclipse Berry the highest-tier crop in Grow a Garden?

Yes. Eclipse Berry is Prismatic, the top rarity in the crop ladder. It sits at Reward Track Stage 20 and costs 252 cumulative points to unlock.

Can I get Eclipse Berry without spending Robux?

Only if you already have a substantial points bank from playing the event since August 1. From a fresh start on August 23 with the event closing August 29, the free ceiling is roughly 108 points — not enough to reach Stage 20 at 252.

Does the 89 Robux quest skip actually give me the point?

The wiki does not confirm either way. Treat the skip as the price of getting past a quest you cannot or will not do (like a Hard-tier craft objective for an item you do not have), not as a guaranteed 1-point buy.

What does Corn Synergy actually do?

On a proc, Cornling moves every mutation from a mutated fruit onto a plain fruit somewhere else in your garden. For each Corn planted in your garden, the odds each individual mutation stays put on the original fruit go up — making Cornling a mutation duplicator when paired with Corn. The proc rate and the per-Corn scaling factor are not yet on the wiki, and any specific number circulating on TikTok is invented.

When does Harvest Moon end?

August 29, 2026, per the Harvest Moon Event wiki page. Part 4 is the last new content window before the event closes.

Are there any new Grow a Garden codes for Part 4?

No. The active list is still torigate, BEANORLEAVE10, and RDCAward. No launch-day code shipped with Part 4.
