Dear Readers,
From the platform with a hole in it from the previous post, I hiked west along the cliff of Karusa Valley until I came across a metal block puzzle. The block I needed was further west and on top of a big rock pillar that seemed to be bombable from below. I didn't bother bombing it though. I just used Magnesis to move it gradually back to the puzzle so I could get another Korok seed. I don't know if you can actually blow up that part of the stone pillar. I might check that out next time.
I could start hearing the hostile environment music since I was very close to Gerudo Highlands. I might just start searching for seeds there next since I was now finished with Karusa Valley...
...and that's no joke!
