Field Items

Zelda: Twilight Princess Guide - Field Items

Large Chest

Chests come in two sizes: large and small. They also only come in a couple different colors. The large chests generally hold something very important, while small chests rarely hold anything necessary to your quest.
 

Golden Bugs

Golden bugs are needed for a side quest. Often you'll see them before you can actually catch them.

Poe lantern

The real Poe

Poes are also needed for a side quest. When in human form, avoid them at all costs. They can take a whole heart away in one attack that you cant even see. In wolf form, you can use your animal sense to sniff them out and fight back.

Heart Piece

Heart pieces increase your overall health. Collect 5 for another heart.

Enemies

Enemies come in many shapes and sizes. You don't have to fight most of the enemies you come across, but it can make your life easier. Overall, I'd just run past all of them when in Hyrule Field.

Shadow Insect

Shadow insects are found only in the twilight. They drop the Tears of Light when defeated.

Misc. Field items

Rupees, bombs, arrows, hearts. You can find these by defeating enemies or cutting down tall grass. They restore their respective areas. Hearts heal health by 1. Rupees are used as money and come in several sizes.

Horseshoe Grass

These are special pieces of grass that can call nearby animals. They are used to call Epona. There is another type of grass very similar to Horseshoe grass that is used to call nearby birds. 

Bombable rock

Bombable rocks are easy to tell apart from other rocks, do to their crumblier or cracked appearance and the suspicious location. These rocks can be cleared out by any explosive force (bombs, bomblings, bomb arrows, ect)

Torches

Torches usually all look about the same. Some need to be put out with the boomerang, while others need to be lit with the lantern. Not all torches are used to solve puzzles, some just light the way.

Jars

Jars come in several shapes and sizes. They never hold anything important (except Ooccoo), but often hold hearts, rupees, and even pink fairies.

Pink Fairy

If bottled and saved, pink fairies can revive you up to 8 hearts if used at a later time. If you die while you have a pink fairy in a bottle, they will automatically revive you and heal up to 8 hearts. Pretty handy little thing, eh? You can usually find them just before the door to a boss fight. After the Cave of Ordeals, pink fairies can be found abundantly throughout Hyrule (specifically around fairy fountains).

Clawshot Target

You wont be able to use these till later in the game, once you get the Clawshot. The Clawshot acts like a grappling hook, and these targets are pretty much the ONLY thing the Clawshot will stick to. So you cant go playing Tarzan like you did with the Hookshot.

Spinner Track

Another one you wont be using for even longer into the game. This track has grooves which are a perfect fit for the Spinner. Just activate the Spinner and coast into one of these to rocket off along the wall.
