Rock

Rocks are found in virtually every Zelda game. The term "rock" or "stone" is generally reserved for such an object that acts as an obstacle, or can be destroyed to find Hearts, Rupees, or other spare items like arrows and bombs. They can be removed in a number of ways, depending on the game, such as picking them up and throwing them, breaking them with a hammer or blowing them up with a bomb. If a rock is thrown, it can damage enemies.

The Legend of Zelda
Link can only push certain rocks, and only after he has obtained the Power Bracelet. The boulders that fall off of Death Mountain are occasionally classified as Rocks.

The Adventure of Link
Link is only able to destroy boulders in his path in the overworld after he has obtained the Glove.

A Link to the Past
Most rocks are denoted by a light green color, though some darker heavier ones can seen throughout Hyrule. Though Link can't initially pick up or destroy any type of rock, the Power Glove enables him to carry lightweight rocks, and the Titan's Mitt allows him to lift and throw heavier and even larger rocks than himself. Throwing a rock at an enemy will heavily damage it, usually resulting in an instant-kill. The most common rocks can be destroyed with the Magic Hammer, and charging into them with the Pegasus Boots can eradicate piles.

Though the placement of rocks are generally used for visual appeal, there are a few rocks with more meaningful locations. Aside from being a general obstacle and barricade in many places, some hide holes and entrances to caves, and others Magical Warp Tiles. Removing these rocks is necessary for Link to collect all Heart Pieces and gain access to new areas.

In the Dark World, rocks are replaced with Skulls, and may occasionally turn out to be Stals. Skulls hold the same characteristic as rocks in many regards, one being that light green ones are more common, and dark green ones require better equipment to lift.

Link's Awakening
There's only one type of rock, and Link requires the Power Bracelet in order to lift and throw them.

Ocarina of Time
As a child, certain small rocks can only be picked up after having obtained the Goron Bracelet. A Kokiri boy can even be seen attempting to pick up a one of these small rocks in Kokiri Forest, with little success, proving the point that a child's strength is not enough to deal with these rocks. Though these rocks do not play a huge role other then scenery and dropping items such as Hearts, Rupees, or other spare items like arrows and bombs, some can be found placed in circles through out Hyrule. These rock circles are usually visual hints that there is a cave entrance encircled by the rocks, sometimes with the hole already open. Link only needs to place a bomb in the circle of rocks to open any closed entryways, or use the Megaton Hammer as an adult, destroying the small rocks in the process. As an adult, these small rocks can be picked up without the aid of any equipment.

Large rocks can also be found in many places, as Young Link and Adult Link, with Young Link only being able to blow them up with explosives like Bombs or Bombchus as a way of dealing with them. Adult Link can pick them up with the help of the Silver and Golden Gauntlets, throwing them away causing them to break apart upon hitting the ground. He can also use explosives as a way of destroying them, or hitting them directly with the Megaton Hammer. These large rocks are constantly blocking paths, and sometimes hide cave entrances underneath them. They have also hidden chests within large groups of them, and on even rarer occasions blocked sunlight from dungeon rooms.

Majora's Mask
The small rocks return from Ocarina of Time, and Link can lift them without aid. "Bomb-able" rocks return as well, but larger boulder-size rocks can no longer be lifted at any point in the game.

Oracle of Seasons and Oracle of Ages
The same type of rocks return from Link's Awakening, and they can only be lifted with the Power Bracelet.

Four Swords
Some rocks surround Stone Arrghus, the boss of Eastern Temple. Some Puzzles involves Link pushing rocks as well.

The Wind Waker
Though Link can lift and throw pots and other common objects, lift-able rocks are very uncommon, especially in comparison to previous games. The only handful that can be lifted are the Stone Head rocks, which are very distinct in appearance, and can only be lifted after the Power Bracelets are obtained. Bomb-able rocks appear as well, but once again, are much rarer than in previous games.

The Minish Cap
The same type of rocks return from Link's Awakening, and they can only be lifted with the Power Bracelet.

Twilight Princess
Rocks can be destroyed with the explosions from one or two bombs.

Varieties
The most common Rocks through out the series are small and large rocks, and are generally the easiest to deal with. However, there are other varieties of Rocks that require improved equipment or even special items in order to be dealt with. Some Rocks even have unique features.

Dark Rock
This Rock is seen in and, and is the counter part to more common rocks in there respected game. This Rock usually requires the highest form of strength to move, Titan's Mitt and Golden Gauntlet respectively. The Dark Rock found in however, can be destroyed with the Megaton Hammer, but requires more hits then the normal Large Rocks.

Black Pillar Rock
Black pillar-like rocks appear in Ocarina of Time. They appear late in the game and are only found blocking the tunnel to the Great Fairy Fountain outside of Ganon's Castle, as well as in certain barrier rooms inside the castle. They can only be picked up with the Golden Gauntlets, and are immediately thrown. Even with the aid of the Golden Gauntlets, it is clearly a heavy object, and is more strenuous to lift and throw.

Sparkling Rocks
This type of rock appears in, and has little glimmers of green light that bounce off it. If Link picks up the rock, it will act as a normal rock. Though if struck by a sword, it will have green Rupees fly out every time it is hit, for a limited time. If Link hits the rock fast enough before time runs out, the rock will occasionally drop a higher value Rupee.

Large Cracked Rock
Found in.
