Grow a Garden Harvest Moon Part 3 Is LIVE: Every Robux Buy-Outright Price, Every Full Craft Recipe & What Bountiful, Threshing, Lunarbound and Starry Pet Mutations Actually Do (August 15, 2026)

Last Verified: August 15, 2026. Every Robux buy-outright price, Moon Coin cost, craft recipe, ingredient count, craft time, summon-count gate, pet mutation passive line, mutation chance, and sell multiplier below is pulled directly from the official Grow a Garden Fandom wiki via the MediaWiki API this morning — the Harvest Moon Event page, the Pet Mutations page, individual pet and crop pages, and the Codes page. Sell values for the three new seeds are still TBA on the wiki — no invented Sheckle numbers below.

Grow a Garden Harvest Moon Event Part 3 goes live today, August 15, 2026 — and the wiki now has every number that was TBA in yesterday’s preview. The buy-outright Robux prices, the full recipe ingredient lists, the pet mutation passive lines beyond just sell multipliers, and the Moon Machine cost and duration tables. This is the launch-day rundown for anyone loading in tonight and trying to work out where their fruits, Moon Coins and level-50 pets should actually go.

As someone with thousands of hours in the original Grow a Garden, the shape of Part 3 is familiar: a Mythical ceiling pet on a hard summon gate, a Divine seed on an even harder gate, a Rare filler pet, a bunch of Robux skip buttons, and one absolutely brutal recipe line halfway down the craft list. The recipe line is what will surprise you.

What Actually Changed Since Yesterday’s Preview

• Every buy-outright Robux price is now locked in. All six craftables were TBA yesterday. Harvest Golem lands at 699 and Harvest Melon at 719 — the two big-ticket items sit inside a 100 Robux band, which tells you where the developer thinks the top-tier chase actually lives.
• Every recipe ingredient list is confirmed. Harvest Golem needs a Moon Egg AND a Mythical Egg. Both. Harvest Melon needs a Moon Chest on top of three separate seed ingredients. Those two lines change how you plan tonight.
• The four pet mutations have their real passive lines. Yesterday only the sell multipliers were known. Now the actual effects are on the wiki — and two of them do meaningful things that have nothing to do with sell value.
• The Moon Machine duration table is different from what the preview quoted. Current wiki reads Common/Uncommon 15 min, Rare/Legendary 30 min, Mythical 45 min, Divine/Prismatic 1.5 hours. If you had planned for long overnight Prismatic locks, the lock is much shorter than expected — which is a good thing, because it means faster rerolls.

The Full Moon Crafting Recipe Table

Every row below is straight from the Harvest Moon Event wiki page. The Robux column is the buy-outright price (skip the craft entirely and receive the item). The 39 Robux craft-time skip applies to every recipe.

Buying outright skips the summon gate, the recipe, and the craft timer in one press. That is why the top two items are 699 and 719 Robux and the lower-tier items sit at 99–289. The pricing floor is not craft time — it is rarity.

The Harvest Golem Recipe Line — Two Eggs, and Why It Matters

The line reads: 1x Moon Egg + 1x Mythical Egg + 1x Burning Bud Seed + 1x Romanesco Seed + 70 Moon Coins. Look at it again.

A Moon Egg is the top-tier event egg from the Moon Event Shop — 50 Moon Coins per drop or 149 Robux, with an 8.33% stock chance every 15-minute restock. A Mythical Egg is the base game’s Mythical-tier egg from the standard Egg Shop rotation. Requiring BOTH is unusual — the game normally asks for one high-tier egg on a Mythical craft, not two. The recipe pulls from two entirely separate egg economies at the same time.

That changes the prep order. Before you queue anything into the Moon Machine, before you plant Wheatcap, you want a Moon Egg sitting in your Egg Inventory. The 8.33% shop stock chance is not high — you may need several restock cycles to actually see one. And you need a Mythical Egg on top. Nine out of ten accounts crafting Harvest Golem this week will be gated by the Moon Egg drop, not by the summon count.

What Bountiful, Threshing, Lunarbound and Starry Actually Do

The Pet Mutations wiki page now carries the full passive lines. Yesterday only the sell multipliers were confirmed. Here is what each mutation actually gives the pet you feed to the Moon Machine.

Bountiful (47.5% chance, x20 sell)

“Medium increase to XP. Grants a 5–10% chance for Night-type fruits to duplicate when collected!” XP boost is 15%, duplication chance sits at 5–10% and specifically triggers on Night-type fruit collections. Almost half of every Moon Machine cycle lands here. If you are farming Night-type fruits at scale, Bountiful earns its keep. If you are not, it is the roll you were hoping to bypass.

Threshing (35% chance, x30 sell)

“Medium increase to passive. Grants a 6–12% chance not to consume a Reclaimer or Harvest Tool!” Passive boost 15%, tool preservation 6–12%. This is the mutation that pays back in consumables saved. On accounts that burn through Reclaimers and Harvest Tools every session, Threshing quietly reduces one of the game’s biggest hidden costs.

Lunarbound (15% chance, x50 sell)

“Big increase to XP and size! Fruits collected have a 2.5–5% chance to get the Moonbound mutation when collected!” XP boost 20%, size 130%, Moonbound-on-collect 2.5–5%. This is the first mutation on the list that applies a crop mutation post-collection — a mechanic previously locked to a small handful of weather-based pets. If Moonbound turns out to be a high-value crop mutation (still being player-tested), Lunarbound becomes far more than a 15% XP number.

Starry (2.5% chance, x80 sell)

“BIGGER boost to passive and XP. Every 4:00–2:00m, advances the cooldown of a random pet ability by 20–40s for every pet in your garden that has the Starry pet mutation!” Both passive and XP get 25% boosts. The cooldown reduction is the real prize — every 2–4 minutes, a random pet ability gets 20–40 seconds shaved off for every Starry pet in your garden. That last clause is the one veterans should read twice. Starry is the first mutation in Harvest Moon history whose effect explicitly scales with the number of pets carrying it. Two Starry pets means two independent cooldown-advance rolls per cycle. Three means three.

Moon Machine Reference — Cost, Duration, Every Rarity

Feed a level 50+ pet in, pick a rarity, wait, get a mutation. The odds column is fixed regardless of input rarity — rarity only controls the Moon Coin cost, the Robux skip price, and mutation duration.

Two calls to make. First, the mutation is timed. Even a Prismatic-tier roll only holds for 1.5 hours — plan your best rolls to overlap with your longest active-play session, not overnight. Second, the odds do not change with rarity. Feeding a Common pet is just as likely to land Starry (2.5%) as feeding a Prismatic. The rarity choice is about mutation uptime and Moon Coin economy, not the odds table.

Craft Priority — What to Build First Tonight

1. Starry Strawberry Seed first. No gate, 10-minute craft, cheap recipe. Unlocks the Moon Crafting UI and drops a Starry Strawberry Produce for the Moonbeam Radar recipe.
2. Queue your first three summons. 10 fruits each, 10-minute duration, 10-minute cooldown. Do not skip — fruit cost is trivial and you need the counter.
3. Craft Wheat Crow at 3 summons. Rare, cheap, 15-minute craft. Its growth-advance passive helps every subsequent craft you set up.
4. Farm Moon Egg drops in parallel. This is the real Harvest Golem bottleneck — watch the shop restock every 15 minutes.
5. Wheatcap Seed at 6 summons. Mushroom-heavy recipe — if you were not planting Mushrooms already, plant them now.
6. Harvest Golem at 9 summons, ONLY once you have both eggs secured. Otherwise the 90-minute craft timer becomes a bottleneck for nothing.
7. Harvest Melon Seed at 12 summons. Endgame craft, needs a Moon Chest, 2-hour timer.

The Robux Buy-Outright Math

Full buy-out on every craftable is 2,204 Robux — roughly $27 USD at standard conversion. The prices reward specific bypasses more than others:

• Starry Strawberry 99, Moonbeam Radar 199, Wheatcap 199 — skip. Recipes are cheap. Not worth the Robux.
• Wheat Crow 289 — only if you need to skip 3 summons AND you do not have a Rare Egg.
• Harvest Golem 699 — the buy-out most veterans will actually consider. Skipping the double-egg bottleneck is the whole value proposition.
• Harvest Melon 719 — the highest price and the tightest gate. Twelve summons is roughly four hours of play plus a 2-hour craft. If you have four hours to sink, do not spend the Robux. If you do not, this is where the buy-out earns its price.

FAQ

What is the cheapest way to unlock Harvest Melon?

Unlocking Harvest Melon requires 12 Harvest Moon summons at 10 unfavorited fruits each — 120 fruits total — then 1x Watermelon Seed, 1x Fennel Seed, 1x Crimson Thorn Seed, 1x Moon Chest and 120 Moon Coins to craft. There is no cheaper path than grinding summons and Moon Coins. The alternative is 719 Robux buy-outright.

Is Starry worth chasing on the Moon Machine?

At a 2.5% roll rate you should expect around 40 attempts per Starry mutation on average. If you can afford to run more than one Starry pet, the compounding cooldown-advance line is what earns the grind. For a single Starry roll, the sell multiplier alone rarely covers 40 machine cycles at 800+ Moon Coins per Mythical input — you would spend more than you make back unless you are selling ultra-high-tier pets.

Does the Moon Machine consume the pet?

No. The Moon Machine mutates the pet and applies a timed passive that expires after the duration shown in the table above (15 minutes for Common, up to 1.5 hours for Prismatic). The pet remains yours after the mutation timer ends.

Can I stack Bountiful pets to boost duplication chance?

Duplication triggers per collection event on Night-type fruits, so multiple Bountiful pets raise the odds of any given collection triggering a duplicate. Starry stacks more dramatically — its cooldown-advance line explicitly scales with the number of Starry pets in your garden.

Was the Moon Team Event brought back for Part 3?

No. The wiki notes the Team Event was removed in Part 2 and has not returned for Part 3. Personal and team-track rewards are frozen at whatever players earned during Part 1.
