umm well if you have the map look at it and on the very bottem of the scream it shows a chest go to were the mini boss was and go to the right door i think then where you see the tile that you jump on where the grass is that falls . then after you do the tile go in the door and there is a crack in the wall like what the wall looked like when you go the map..

Sorry, i guess the map didn't turn out quite as good as i typed it. (Stupid reformatting system!)

Quick Reference:
1-D6 Entrance
B-D3 Roc's Feather (in cave)
1-E5 Compass
1-E4 Gasha Seed
1-G3 Boss Key
1-D4 Map
1-B2 Miniboss: OWL'S REVENGE
1-G2 Boss: WHEEL O' BOSS

If you don't have a shield, you need one, because in D5 you'll have to flip
the spiky enemies to kill them and open the left door. The colored block
puzzle in C5 is a little harder- to solve it, push the block right three
spaces, up 1, left 1, down 1, and left into the hole. As you pass through
C4, bomb the wall on the right to get the MAP, and continue to A3, where you
simply kill the enemies for a key. Now go back to D5 and use the key on the
right-side door. First, bomb the bottom wall and enter the passageway to F7,
where you'll find another key. Back in E5, kill all of the snakes to make
the block move, then move it out of the way and get the COMPASS. Go on to D4
and ride the minecart to B3, then go up to fight the Miniboss, OWL'S REVENGE.
To beat him, run along the blue border until he flaps his wings fast, then
move out of his way. When he drills the ground, slash him. After 6 hits he
goes much faster and bounces 2-3 more times. At 10 hits he dies. Keep in
mind that if you fall down a hole, you will end up in B-B2 below; simply go
right one screen and up the stairs, then left into the miniboss room. His
life resets, though...

After beating him, exit the upper-right door and go down the stairs and down
one screen. This is B-C3. Avoid the arrows and walk along the edges, then
enter the cave in D3 and get the ROC'S FEATHER. There are 30 Rupees in the
narrow passage to your left; jump on the Thwomp to get them. Back in the
room, jump over the tile (on the right) twice to change its color. In E3,
jump on the minecart, then slash the yellow switch as you pass by it. You
will stop in E2. Then bomb the right wall and kill the enemies for a key.
Go back a room and roll the block left, up, right, and up to raise the bar
blocking the road. Take the minecart into D2 and match the pattern on the
floor by jumping the left two tiles once and the right two tiles twice.

Now, back to 1F, via the same stairs as before. Unlock the key-rock and jump
down to the other stairs. Go down one screen and jump your way to the tile,
then leap over it twice to clear the path. Now go back to the other side of
C2 via the miniboss room and take the minecart from there to E4. You can get
the GASHA SEED or go straight to E3. In E3, kill all the enemies and clear
out all but the upper right pot. Then carefully push the pot onto the
switch, using the Feather to get into position. In the next room, go down a
screen and move the statues to match the pattern on the left. There's one
catch- you can only move the statue whose color matches the tile at the top
of the screen. Advice- do the yellow statue first, then red, then blue.
Next, go to G4. These are crafty baddies- they change color to match the
tiles below them. You can't hit them unless they're the wrong color. So
change the color with the center tile, then smack them before they change
again. Luckily, they take one hit each. This gets you the BOSS KEY. Go
left and up, then avoid the Wallmasters and enter the lair of...

BOSS: WHEEL O' BOSS
This is actually a sidescrolling battle; go up the stairs to find the boss.
Its only real attack is to throw fireballs and the occasional bomb refill out
of its head. If you're on the top corners, you can't be hit. Once there, get
a running start and toss a bomb into the boss's head. It will start spinning
(thus the name), and depending on what you land on, different things happen:
Purple- A rockslide starts. Stand underneath the first rock ledge and watch
your head.
Blue- Little fireballs. Stand on the second brick on the ground to avoid
both layers of fireballs if they appear.
Green- Big fireballs, like the ones the boss usually throws. Go back to the
top corner to avoid them.
Red- You got a hit! Grab the heart that the boss drops quickly. Four of
those and you get the ANCIENT WOOD.
