The Mole Market, managed by Marvin the NPC, is a shop where you can buy items directly from the site. Each player's stock is unique, so if an item you want is out of stock, try the Flea Market or trade with other players.
On the left side of the page, you'll find Marvin, a countdown timer (shop refresh), and a green "Claim" button. Click the button to get a free, random item every time the shop refreshes.
On the right are the available items, sorted by category. This selection is unique to your account and refreshes every 6 hours (at UTC/site time midnight, 6 am, noon, and 6 pm). New items you haven't interacted with will show a green "New" tag.
Some categories (like food) have a "Buy All" option, which lets you buy all items in that category if you have enough pebbles. To purchase an item, click its icon, select the amount, and click "Buy Items."
Don't forget to check back often for your free items!
