The Golden Pumpkin is a rare item found on Spirit's Eve in Stardew Valley, but there's not a whole lot players can do with the Golden Pumpkin after obtaining it.
Spirit's Eve is Stardew Valley's version of Halloween. It takes place on the 27th of Fall each year, and like Halloween, Pelican Town will be dressed with spooky decorations and interactive activities. But unlike many other events and holidays in Stardew Valley, there are no contests to be won on Spirit's Eve, though there is a maze that was supposedly created by the Wizard. On Spirit's Eve, players can purchase some festive items such as a rarecrow, a Jack-O-Lantern, and the Jack-O-Lantern recipe from Pierre's booth, but the Golden Pumpkin is more difficult to find.
There are two ways Stardew Valley players can obtain the Golden Pumpkin. One way is by completing the haunted maze. Using a Glow Ring will make it easier to see, but otherwise, use the old "keep going left" maze trick until a sign with a question mark appears. Sam will say this is a dead-end, but this indicates a secret passage. Walk straight through the bushes and up into the mine shaft. Follow its path; at the end of the tunnel will be a chest with a Golden Pumpkin inside.
The other way to obtain a Golden Pumpkin is by opening up an Artifact Trove, a type of container that contains rare items. It can only be cracked open like a geode at the Blacksmith's. Artifact Troves can be purchased from the Desert Trader in Stardew Valley for 5 Omni Geodes, dropped by Haunted Skulls in the skull caverns, found in supply crates on the Beach Farm in the 1.5 update, or dug up from Artifact Spots.
Unfortunately, there's not a whole lot the Golden Pumpkin is useful for in Stardew Valley. It's a universally loved gift, so it can be given to any villager in Pelican Town. It's also worth 2,500 gold if the player wishes to sell it, but the most unique way to use the Golden Pumpkin is by crafting clothing. Combine some cloth and the Golden Pumpkin at Emily's sewing machine to create a Witch Hat.
To tailor items in Stardew Valley, players first need to acquire cloth. The morning after doing so, Emily will offer to let the farmer use the sewing machine in her home. Alternatively, complete Emily's Rock Rejuvenation quest to obtain a sewing machine for the player's home.
Stardew Valley is available now on Mobile, PC, PS4, Switch, and Xbox One.
