I made my way through the volcano and I ended up getting something new: Digging mitts. They let me dig into the ground where there’s an X.
Continuing on, the path led me back outside and I continued up the mountain. At one point, a mysterious woman in black helped me out. Interesting.
I reached a temple that was locked. Turns out I needed five keys hidden all over the mountain to get in. I used my dowsing ability to help me out, even though it sometimes misleads me. It will act like a spot on the ground is where the item is, but it’s not. It may be in that direction, even through the ground to a lower level. So that threw me off for a while. I made a couple circles around the mountain and I eventually found all five keys, which combined into one.
I then made my way to the temple entrance and saved my game. I’ll go inside next time.
