Here's one thing I find interesting. Why is Link supposedly in excruciating pain when putting on the transforming masks? Is it the awkward transformation into the bodies? If yes, that would make sense too. But it's sort of hard to explain. And I haven't read the Stone Tower Temple theory yet. But I'll be sure to google it and read it over, even if it is a lengthy read.
Anyways, I should give a progress report on my gameplay as of now:
- Got the gilded sword, and won the Goron race. I just barely won the latter, so I was glad to get that out of the way.
- Did the alien challenge in Romani Ranch. Which was easier than I expected. And got the Romani mask, so now I can enter that Milk club. And yes, I got Epona back and learned Epona's song as well. Life gets so much better once you get her back.
- Went to Ikana Graveyard to race that giant skeleton for the Captain's Mask. And GOOD LORD is this race a chore to finish. I seriously had to start all over three times just to get it right. It is very frustrating. Though if you play Inverted Song of Time and wear bunny hood, you should do okay. Easily one of the hardest masks to earn ever.

- Went into the graves, mask in hand. The first night you learn Song of Storms, second night you get a heart piece. And on the third night you have to do a grave digging activity with Dampe. It was so frustrating him doing the wrong way and getting caught by the Wallmasters every 5 seconds, that I just gave up.
- Went to Great Bay today, for the hookshot in the Gerudo/Pirate fortress. Wearing the Stone Mask helps wonders, the Gerudo guards don't suspect a thing.
- I also did that challenge at Pinnacle Rock where you reunite those seahorses. Man, that was a tedious challenge. Last time I replayed this, I gave up because I found it so hard. But it's not so hard as it is time consuming. I finally killed all those huge creatures, and got a heart piece from it. How I even finished that challenge is beyond me.
- Oh yeah, and I collected all the Zora eggs and learned the "New Wave Bossa Nova" song. So I've basically covered every bit of the main portion of Great Bay.
And, that's my progress in a nutshell.

Next I'll snatch up some more heart pieces (already completed yet another container today). Then, I'll cover the latter portion of Great Bay, where all the Zoras are with that band. I should reach Great Bay temple by the end of the week.
