Okay here's some funky stuff I figured out

Really helpful stuff
 (at least for me)

Okay In the spirit temple there is a place where there are a bunch of climbing walls that slide back and forth. It can be really annoying to climb well just use your hookshot. Surprisingly enoughtit will latch onto the stone and pull you all the way up to the top. Incredibly obvious huh?

In the same temple when you are beating the iron knuckles. don't let them smash you apart with that wicked axe. Use Nayru's love already! If you don't know what I'm talking about let me just say palm trees and bombs.

Okay how about in the forest area the big dud with the club you know what I'm talking about. He knocks you on your uh anyway just run to one side and the other and you can edge past him. get behind him and hack him up with your sword.

Get DEM rupees/get ridda them
Okay the best place in the whole world to get rupees(repeatedly anyway is the lost woods as an adult. Did you run into the skull kids? If you can kill one of them he'll leave a whopping 200 rupees behind!

If you don't want that much cash did you also know that you can break open those beehives you find in underground caverns(with your hookshot and they will usually give you 20 rupees.

More stuff. . . . .

Run into trees and rupees or arrows and occasionally skulltulas! will drop out.
There's a little spot over in the area where jabu jabu is that you can climb up into but I don't know what it's for.
If navi turns green for no apparent reason play the song of storms and sometimes a fairy will appear. also if you play the scarecrow's song sometimes a scarecrow will appear. Also the song of time will bring blocks and epona's song will occasionally call fairies as well.
