Lanayru Sand Sea
The Lanayru Sand Sea is an area in Skyward Sword. It used to be an ocean, but it dried out and filled with sinksand.
Despite the Lanayru Sand Sea being entirety full of sand, the timeshift stones conveniently placed on a boat allows Link to travel throughout the sea as it was when it was full of water and also allows Skipper to talk and interact with Link guiding him throughout the sea. The boat travel is similar to travel in The Wind Waker and Phantom Hourglass as it allows travel in water and is equipped with a cannon.
