it's just a rectangle, i know
The Kaorin Bush is created by the Creator after the Hero collects a page for the Book of Life, from Isaac who traded Count Choco tomato juice for it.
These bushes are placed near the Snow Gate, and they are considered to be dangerous if used improperly. Samuel tells the Mayor that a berry from the bush will help to increase the Hero's size for the Rapoville Gate.
Trivia
- After you get the Kaorin Berry Bush Page and plant them, the Mayor will refer to them as "Kori Berries" instead of "Kaorin Berries", then later he says "Kaorin Berry". Though "
Kori Berries" could just be a shortened version of the name.
