I have two problems, three if you count that I am not very good at this (I'm using a detailed walkthrough and it's still not easy for me). I am in the water temple and am battling the Twilit Giant Aquatic Morpheel. The first is, I could use some suggestions for swimming - namely staying above the creature while it circles without getting sucked in and launching the clawshot to grab onto the large eye at just the right time. I did it once but died afterwards. It's really easy to get disoriented when swimming. I sometimes don the iron boots to sink, plus you can Z-target in that mode.
The next thing is that I missed a couple of pieces of heart or a heart container earlier in the game. I know one of them is in a cave found in the land with the acid-like fog where you have to follow the monkey. Is it possible to get back there and retrieve them?
I got impatient and didn't spend much time exploring before I went into the temple under the lake. I need to go back and do some fishing and some of the other mini-games, but I think Link turns back into wolf form when the big boss is defeated. I tried to go out with the Occoco but was repeatedly taunted by Midna to return to the temple. So can this exploration wait until after Link gets back to human form or should I just scrap this quest and begin anew?
