Hell Awaits Help

I posted this on another forum--hoping to get some help here too:

Hi Everyone,

I need some help with the Hell Awaits quest. I got the I got the Triforce from levels 1-4, but now I am totally stuck. There is a part at the end of Level 4 with a room with like 5 Magic Otorocks. After facing that, I get to the cross part of the level. At the top of the T is more magic octocrock--after finally beating them I get to the last room of the cross. It has a locked door along with a temp. bubble, statues with fireballs, a bunch of Magic Octorocks, and some other stuff (I didn't get to see it long enough to remember everything.

Here is what I have:

10 Heart Containers, White Sword, Shield, Book, Money Bag, Magic Boomerang, 8 Bombs, Blue Candle, Bow and Arrow, Whistle, Red Potion.

Basically, I am not equipped for this fight.

I've gone back through all 4 levels literally dozens of times (I love this quest). I'm reasonably sure that I need the hookshot or the raft to move forward.

I am already 6 and a half hours into the game. Everything was going smooth until I got to this part.

If you know anything about this quest, please tell me what I am doing wrong. I'm pretty good at the Zelda games and I am totally stuck. And obsessed.

Anything you got would be super.

Thanks!

The hookshot is in lv4, but I don't remember exactly where I found it. You need it to cross an area to the right of lv4 to enter the cave that takes you to lv5. The ladder is in lv5. You don't get the raft until lv6. That's as far as I got.:)
