Kannst du einiger maßen englisch??? naja google kann dir ja auch helfen.... hier das is die lösung vom 3. bis zum 4. Dungeon halt auf English aber sie hat mir auch scho weiter geholfen!!! :

Use the Ocarina, and get back to town.

Go east from your house. Tingle will be standing on a platform. Talk to him,
and fuse a stone with him. After that, go to the farm, and you'll see Tingle
on a platform. Go there, and fuse a stone with him too. After that, go to the
lake. You'll find one here too by following the path. The last one is west
from town. Pretend like you're going to the mountains, but instead of entering
the screen west, go up the bridge and bash through the door. You'll find 2
chests here that contain 2 blue stones. Climb the ladder and merge a stone
with the final Tingle. You can also shrink and fuse with the little elf inside
the house. Go to the place where all the entrances are unlocked, and fire each
light, by stepping on the switches. Also open the chests for stones and
shells. When all the fires are burning, a new entrance will be created. Go
there and open the big chest for an upgraded boomerang.

Warp yourself to the lake. Shrink and talk to the elf. Fuse a stone with him
too if you want. Go back to town, and find the library. It's a bit west from
the northern entrance. Enter it. Go up, and flip the bottle of. Shrink, and
enter the library. Climb the bookcase, and talk to the elves. They want you
to get books.

Fill the bottle with water. Then go to the house with the dog, and use the
water on the fire. Enter the chimney. Walk to the other room, and climb the
closet. Push the book down, and return back to normal, and go get the first
book. Return it to the library, and talk to everyone. Also be sure to read the
notice board.

Fill your bottle with water again. Now go to the southwestern part of town,
and enter the house that's close to the dog running around. Use the water on
the fire, and shrink by going into the workers house. Now enter the house
again when small, and follow the path (go in the chimney). You'll end up at
the fountain, where you can enter a hole. There is only one path to take;
east and then north. Kill the lice and open the big chest for a power ring.
You can now lift heavy objects when you're small. Go back to the house where
you started this little journey. Move the closets to the left, and go to the
hole you can reach now. Here, suck the dust at the southwestern corner away,
and use the 2-Link technique. Then go to the east, and north, and step on the
book. It will fall down. Grow again, and go get the book. Return it to the
library. Be sure to talk to everyone again and read the notice board.

Walk to the witch hut. On your way you'll encounter a rock door. Go in there.
You'll find a chest here with a blue stone, and in the northeastern corner,
you'll find a small stone on the wall, which you can fuse with. It'll make
the Goron you met earlier dig harder, and he'll open an entrance. We'll go
there in a second. Climb the ladder, and find a tree. When you run into it,
it'll turn into a stump. Use it to shrink, and enter the house south of you.
Push the closet to the right, and push the book off. Grow again, and go get
the book. Now return to the library and return the final book. The old man
will rush in and get them.

Go upstairs and shrink again, and go to the bookshelf again. Talk with the
first fairy to get 50 rupees. Then follow the path in the east, and you'll
end up in a book. Talk with the guy here (fuse first if you want), and you'll
fall down. Follow the path (nothing strange), and fight the 2 enemies in the
final room. Open the big chest for flippers. You can now swim around. Swim
south and leave the small dungeon.

You can do even more things now, since you have your flippers, but I'll
discuss most after the next dungeon. Teleport yourself to the lake. Go to the
house with the dog. Dive in the pool next to it, and you'll find a piece of
heart. After that, head south until you find another one. After that, look
on your map and go to the next dungeon. Shrink to get in.
