Castor Wilds is a swamp-like area in The Minish Cap. Link must use the Pegasus Boots, which he gets from Rem the shoemaker, to cross swamps here. In this area, Link must collect three gold kinstones to open the way to the temple. The item that Link obtains in this area is the Bow, which can be used to defeat the small Eyegore statues scattered around. When you are a Minish, this area is full of Mulldozers. When you are normal size, this area is full of Ropes and Peahats.
This area is also home to some kinstone goodies and Swiftblade the First, the sword master who teaches Link the final technique in the game. However, his den is hidden until Link fuses kinstones elsewhere. Other rewards in this area include additional Minish homes and floating leaves for Minish Link to ride on.
