Cyclone Slate

The Cyclone Slate is a mystical item in Phantom Hourglass, given to Link by Golden Chief Cylos in the Uncharted Island. It is a stone tablet bearing the image of Golden Chief Cylos that serves as the warping function of the game.

The Cyclone Slate can be accessed by tapping on the Menu screen in the lower-left hand corner of the screen and then selecting the slate. To use it, the young hero must find the six Golden Frogs scattered throughout the World of the Ocean King and write down the symbol that they teach him. Drawing a symbol on it will warp him to the area in which he learned the symbol. However, it must be noted that in order to warp to a specific area, Link must first learn the symbol from the specific Golden Frog.

Trivia
It is interesting to note that the slate looks much like a Game Boy Advance cartridge.
