In this guide, you will learn how to get the Rusty Sewer Key while playing Stardew Valley.

You must unlock the Sewers with this key to purchase items like Monster Fireplace, Sign of The Vessel Statue, Solar Essence, and Void Essence.

How to Find the Rusty Sewer Key in Stardew Valley

You must acquire the Rusty Sewer Key from Gunther, the operator of Pelican Town’s museum. He is available from 8:00 AM to 6:00 PM in the museum.

To get the key from Gunther, you must donate 60 items and wait until the next morning. On the following morning, he will come to thank you and give you the Rusty Key.

Your character learns about this key by listening to the conversation between Jas and Vincent in Cindersap Forest. Follow the below steps to get the key:

  1. After learning about the Stardew Valley Sewer Rusty Key, you can head to the Pelican Town’s museum in the southeast corner.
  2. Approach the counter and select “Donate To Museum“.
  3. Drag and place all the items you want to donate on the table.
  4. Go back to the counter and select “Collect Rewards“. You will receive some items like the Obsidian Vase as a reward, not a Rusty Stardew Valley Sewer Key.
  5. Return to your home and wait for the next morning. As soon as you come out of your house in the morning, you will find Gunther standing near your door.
  6. Gunther will talk about how much he appreciates your donation and will give you the Rusty Sewer Key.

How to Unlock the Sewer in Stardew Valley

With the Rusty Sewer Key in hand, go back to the south of Pelican Town to find the Sewer. As you go near it, you’ll receive the following message: “You unlock the sewer hatch with the Rusty Key.”

You unlock several things by accessing this area, such as the Statue of Uncertainty, which allows you to change your profession for 10,000 gold. Apart from that, this is where you find Krobus and Mutant Bug Lai.

Krobus runs a shop with unique fixed and rotating stocks, including Void Egg, Void Essence, Solar Essence, and Iridium Sprinkler. As for the Mutant Bug Lair, you unlock the Dark Talisman quest; its entrance is in the northwestern part of the Sewer. This place has two fish varieties you wouldn’t find anywhere else in the Valley.
