Water (Terrain)
Water, the liquid all natural beings require to live, makes quite the normal, and frequent appearance in the Zelda franchise, in many forms familiar to beings in real life.
Shallow Water
Shallow water, under normal circumstances is not hazardous for Link. A Link to the Past and the majority of titles since, contained pools, puddles, and coastlines in which Link was free to splash through with no damaging effects. In The Minish Cap, while in Minish form, small collections of water were deadly for the Flippers-less hero. While in shallow water Link will retain his ability to use weapons, including bombs-which defuse in deeper waters.
Link is also able to swoop an empty bottle through shallow waters and receive a fill of water, Forest Water, Hot Spring Water, Mineral Water, and possibly even a fish.
Poison Water
Majora's Mask
Poison water can be found in the some places at the Southern Swamp area, along with the Woodfall area, and in the Woodfall Temple. This causes damage to Link's health, but may be safely hopped across with Deku Link.
Four Swords Adventures
Link may pass through poison water at the cost of losing Health. Poisoned water has appeared purple in color in The Swamp of Four Swords Adventures.
Oracle of Ages
The polluted Zora Seas in Oracle of Ages were green and lumpy until Link assisted the Great Fairy in cleansing them. If Link tries to swim through the polluted water, he will be injured and be pushed back.
Deep Water
Link encounters deep water in every Legend of Zelda release. Most of the titles allow Link to swim, usually immediately or after obtaining the Flippers. While swimming above the surface Link is unable to use any of his items or weapons. In Link's Awakening, Oracle of Ages, Oracle of Seasons, and Four Swords Adventures, underwater swimming switches to a 2-D sidescrolling view and allows Link to make sword swipes. In Ocarina of Time and Twilight Princess, Iron Boots can be equipped to sink to the ground and select items such as the hookshot can be used. Staying underwater for prolonged periods of time requires a Zora Tunic in Ocarina of Time, Zora Mask in Majora's Mask, and Zora Armor in Twilight Princess. Beaver Falls Race is a minigame directly related to swimming.
In The Legend of Zelda, The Adventure of Link, and Phantom Hourglass, Link couldn't swim at all.
Diving
Diving in Link's Awakening, Oracle of Ages and Oracle of Seasons was primarily used as a manner of avoiding hits from enemy Zoras. Occasionally there were hidden treasures, or caverns underwater. Oracle of Ages features a unique item called the Mermaid's Suit that not only allowed him to swim faster, but in very deep waters. He can even dive underwater , turning his appearance into that of a mermaid. In Ocarina of Time, Link dove underwater by pressing the A button. By acquiring the Silver Scale or Golden Scale, he could dive even further. The Wind Waker Link was able to swim for a set time, and he couldn't dive.
Crossing Water
Other means of Link crossing deep water have been used as well. In The Legend of Zelda, Link could use a ladder to cross a single span of water, and a raft to float straight out from any of the docks. The Adventure of Link returned the use of the raft, also floating it straight across with no means of steering it. The boots could be equipped to walk on the sea with minor paths of exploration. In Oracle of Ages, Link could obtain a raft from Cheval. This raft was completely controllable. A very large, old Turtle had been awoken in Majora's Mask to transport Link to the Great Bay Temple. In The Wind Waker, Link used a small sailboat, the King of Red Lions throughout the quest as his primary mode of transportation on the Great Sea. Phantom Hourglass also relied heavily on a boat, or more accurately a steamship to travel. Twilight Princess and Link's Crossbow Training only temporarily used canoes.
Rapids
Link is at the mercy of Raging Rapids or strong currents. Although a modicum of control is maintainable. In Ocarina of Time, the currents of waterfalls and Zora's River served to speed up Link's swimming pace. In Link's Awakening, Koholint Island featured a Rapids Ride minigame.
Cyclones
An environmental hazard found in 3D versions of Seas, cyclones serve to dislocate Link and his craft. In The Wind Waker, Link was able to defeat Cyclos for the ability to call down his own cyclones and use it for warping. In Phantom Hourglass, cyclones were much less disruptive and only spun Linebeck's ship around a few times before dropping. These cyclones could be destroyed with cannon blasts.
Whirlpools
Another water related hazard which duals as a warping method, whirlpools appear on the surface of waters. First appearing in 'A Link to the Past, once Link had the ability to swim, the Whirlpool Waterways were useful to warp around Hyrule. Whirlpools in Oracle of Ages were impassable. And whirlpools only showed up in The Wind Waker as Link was fighting Big Octos.
