Forest Water

Forest Water is an item in The Wind Waker.

Location
Forest Water is a mystical, life-giving water that exists only within the Forest Haven. The water is said to be the only thing keeping the Forest Haven, the Koroks, and the Great Deku Tree, alive. When taken the Forest Water is taken outside of the Forest Haven in an empty bottle, the magical properties of Forest Water wear off after 20 minutes. In, Forest Water retains its potency for the increased time of 30 minutes.

The Korok Tree Challenge
The Koroks, during their annual Korok Ceremony, fly about the overworld of The Wind Waker and plant Great Deku Tree-like saplings on several islands. After the ceremony, however, the planted trees that usually thrive and grow to great heights mysteriously wither and slowly die. The Koroks ask Link to fetch Forest Water from the Forest Haven and sprinkle it upon all eight withered trees before it denatures into normal water. If he reaches them all before the Forest Water expires, the withered trees will sprout into grown trees. Using the Hookshot on the grown trees will allow Link to access new heights and previously unreachable areas.

Withered Tree Locations
The withered trees are found on the following islands:
 * Star Island
 * Mother & Child Isles (on the 'Child Isle')
 * Eastern Fairy Island
 * Greatfish Isle
 * Needle Rock Isle
 * Private Oasis
 * Shark Island
 * Cliff Plateau Isles (inside the mini-dungeon)
