You start with 3 active pet slots and unlock more by spending Sheckles — 200,000 for the 4th slot and around 1,000,000 for the 5th, which is reportedly the current maximum.
Grow a Garden 2 only went live on June 12, 2026, so the pet system is still being mapped out by players rather than confirmed in official patch notes. The most consistent picture so far is that extra pet slots are bought with the soft currency, not Robux, and that the ceiling is lower than the first game’s — but a couple of numbers are still soft, so it’s worth knowing which parts are solid and which to double-check in your own game.
What each extra pet slot costs

Early reports consistently give the same breakdown:
- Base: you begin with 3 active pet slots.
- Slot 4: 200,000 Sheckles (total of 4).
- Slot 5: 1,000,000 Sheckles (total of 5), which currently looks like the cap.
These are Sheckles, the in-game soft currency you earn from selling harvested crops — not Robux. The 200,000 price for the 4th slot is the most consistently reported number, so you can treat that one as reliable.
Farm Sheckles
Selling harvested crops is the main income for both upgrades.
Open the pet upgrade menu
The exact NPC, building, and menu label aren’t documented yet — look for the pet/slot upgrade UI in-game.
Buy the 4th slot
Pay 200,000 Sheckles to add your fourth active pet slot.
Buy the 5th slot
Pay around 1,000,000 Sheckles for the fifth — reportedly the current maximum.
Equip your pets
Drop pets into the freed slots and their passive bonuses activate automatically.
Where the numbers are still unconfirmed

Two things are not nailed down, and both are worth flagging.
First, the 1,000,000-Sheckle / 5-slot cap. The second upgrade is often phrased as granting “two more slots for a total of 5,” which is mathematically inconsistent (3 + 1 + 2 would be 6). The likely reading is that 1,000,000 Sheckles buys the single 5th slot and “two more” is a repeated copy-paste error — but treat the 1M figure and the 5-slot ceiling as unverified until you see them in-game. Second, the exact location, NPC, or menu where you buy the upgrades isn’t documented anywhere, so any specific spot you read elsewhere should be checked rather than trusted.
You may also run into an entirely different system: descriptions of a trip to the Pet Eggs Shop to talk to Raphael, choosing “Show me pet info,” then trading aged pets (ages 20, 30, 45, 60, 75) for equip slots up to a max of 8, sometimes with Robux alternatives. That is the original Grow a Garden system. It is widely repeated, but it appears to be carryover that is not confirmed for Grow a Garden 2 — GAG2 is a full redesign with a new map and economy, so don’t assume Raphael, aged-pet trade-ins, or the 8-slot ceiling apply here.
Earning Sheckles to afford every slot
Since both upgrades are priced in Sheckles, the real bottleneck is income. The jump from 200,000 to 1,000,000 is steep, so the practical move is to buy the 4th slot early and keep farming and selling crops toward the fifth. Pets themselves are part of the engine: in GAG2 they spawn in the lobby and are bought with Sheckles when they appear, then follow you and grant passive bonuses like faster growth, free seeds, and movement speed — which feeds back into how fast you earn. Note that this is a key GAG2 change from the first game, where pets hatched from eggs.
Which pets to slot first
More slots only help if you fill them with pets worth running. Confirmed GAG2 map-spawn examples include the Owl for 25,000 Sheckles, the Deer for 50,000 Sheckles, and the Robin for 75,000 Sheckles. Pets like Bunny, Bee, and Deer are commonly suggested for early progression, though reported pet lists conflict — so confirm current spawns and prices in your own session before committing Sheckles.
One trap worth avoiding: don’t confuse equip slots with pet inventory capacity. Equip slots control how many pets are active at once; inventory is how many you can store. Older Grow a Garden information talks about 60 inventory slots, Pet Pouches, and big storage caps, but none of that is confirmed as a GAG2 rule.
Buy the 200,000-Sheckle 4th slot first — it’s the one price that’s consistently agreed on — and hold off on the 1,000,000 fifth slot until you’ve confirmed that cost in your own game, since it’s the soft number.
