As soon as you unlock Bancho’s Sushi restaurant in Dave the Diver, you can start selling standard food-based items, but you won’t be able to sell valuables you find in the blue hole. Cobra’s Shop is the only spot where you can sell items like Gold Bars, and I’ll explain how you can unlock the spot in this guide.
How to Unlock the Cobra Shop in Dave the Diver
The Cobra Shop is unlocked by completing Where the Currents Flow in the first Chapter of Dave the Diver. For this task, I had to pick up a computer chip, a camera lens, and a motor around the 65-meter mark of the blue hole. After collecting all of these pieces around the current, and returning to the surface, I was able to speak to Cobra again.
