need help with zelda v2.10w, please

i wanted to know if someone out there can give me a hint to get past a certain area in the Zelda v2.10w game.

I'm in the "task madness" castle that's located in the water. i can't get the stupid white sword nor can i figure out the task (i'm so pathetic, but i don't have the time to enforce my search and destroy methods like i use to in the classic zelda :cool: ). anyway, i destroyed everything so far in that castle, moved everything that i think can be moved, got the boomerage, and i think i also got the red candle in there too.

i've also been swimming like nobodys business to find a way to get to the other water parts of the map but with no success.

i guess those are my 2 questions:
1.....what do i do in task madness castle?
2.....how do i get to the other parts of the map that seem to be connected to the water?

-thanks.
