Moonlight Peaks Guide: How to Increase Your Inventory Space
Stop Dropping Items: How to Upgrade Your Backpack at the Webb of Wonders

Quick Answer: Visit Sabrina at the Webb of Wonders and tab over to the third page of her shop menu. You can buy your first backpack expansion for 2,000 coins, which adds an additional 10 slots to your inventory.
Running out of pocket space is a rite of passage in any farming sim, but Moonlight Peaks makes it particularly brutal early on. You kick off your adventure with a measly 20 slots. To make matters worse, identical items with different quality tiers refuse to stack together. A handful of standard, silver, and gold crops will obliterate your available space in seconds.
Thankfully, you do not have to suffer with a tiny backpack forever. You can purchase multiple bag upgrades to make your life significantly easier.
Upgrading at the Webb of Wonders
To get more inventory space, you need to pay a visit to Sabrina’s shop, the Webb of Wonders. Most players miss the backpack upgrades entirely because they get distracted by the magic system. When you open her store menu, navigate away from the spellbooks and click on the third tab.
If you are currently hauling around a massive harvest of high-tier produce, like the money-makers featured in our guide to the best crops for maximum profit, you need to buy this expansion immediately.
Here is exactly what you can expect to pay for those precious extra slots:
| Upgrade Level | Coin Cost | Space Added | Total Inventory Size |
| Inventory Upgrade I | 2,000 Coins | + 10 Slots | 30 Slots |
| Inventory Upgrade II | 20,000 Coins | + 10 Slots | 40 Slots |
As soon as you purchase the first upgrade, the second tier will populate in Sabrina’s shop. Depending on how fast you accumulate wealth, it might be waiting for you instantly, or it could require a bit of story progression to unlock. Either way, dropping 20,000 coins completely trivializes the headache of managing unstackable items.

Early Game Storage Solutions
Finding 2,000 spare coins during your first few weeks in town is a tall order. Before you can afford Sabrina’s magical backpack extensions, you will need to rely on old-fashioned storage crates.
- Crafting a single storage crate requires 10 Planks.
- Farming the raw wood drains a massive amount of your daily energy.
- Prioritize building at least two or three crates early on, even if it delays your other crafting goals.
Dumping your excess materials and low-tier crops into chests on your farm is the only reliable way to keep your pockets empty for gathering runs. Grind out the wood, build your crates, and save those pennies for Sabrina.
