Where do you get the folowing items: 1.Clawshot 2.Lure fishing rod..

1.Lake Bed Temple,
2.You don't get one, you rent it to use in the lure fishing area,
3.River Rapids Game,
4.STAR minigame (after lakebed temple in hyrule town)
5.No such thing (from what I can remember)
6.Can't be bothered to put all the games good items here.

The answer aboe isn't fully correct.
Number 5 wasn't answered properly.
You get another bomb bag by helping the river rapids person.
After you help her you can do her mini game. If you win all of your bomb bags will double in size!

1. In Lakebed Temple it comes after a little while.
2. You don't get it, you just use it in the fishing place with Hena(spelling?)
3. I think you are talking about bomblings, as you go through your quest you will receive a letter saying that a new type of bomb is ready.
4. At the STAR game use the clawshot to collect the orbs and eventually, your big quiver.
5. Do the river rapids again this time shooting the pots.
6. All items in the game are useful, and it would be impossible to get through the game without them.

1. You'll get a Clawshot in the Lake Bed Temple and in the City in the Sky lol - keep playing.
2. You rent the Lure Fishing Rod from the Fishing Hole in Zora's River - it's only usable there.
3. Either Water Bomb the Meteor that you Warped to melt the ice in the Throne Room of Zora's Domain or play the River Rapids Game from Zora's River to get more Bombs.
4. To get bigger Quivers, play the STAR Game on the South Road of Hyrule Castle Town and use your Clawshot to catch all of the Orbs.
5. See #3.
6. There's free Rupees when you collect all 60 Poes for Jovani, there's bigger Wallets when you collect all 24 Bugs for Agitha, 45 Heart Pieces, 4 Bottles, 7 Hidden Skills, the Magic Armor, the Master Sword, Ball and Chain, Dominion Rod, Horse Call, Spinner - hmmm, what else can I tempt you with...
