- "If you use the treasure that's hidden on that island there, the thing that vanishes as soon as you get near it...it won't vanish anymore! You know...IT! I'm talking about IT! That thing that appears on nights when a wee bit of the right half of the moon is missing! Don't you know what I'm talking about?! IT!"

Diamond Steppe Island is a location from The Legend of Zelda: The Wind Waker. It is an island located in the Great Sea northwest of Outset Island. Diamond Steppe Island, as its name suggests, is diamond-shaped and has extremely tall terrace-like levels of varying height. One palm tree exists for each level, allowing the island to be scaled with the help of the Hookshot.
On the top "step" of the island is a Hidden Hole. Inside the cavern is a maze of wrecked ships and Floormasters where the Ghost Ship Chart lays, which prevents the Ghost Ship from disappearing when Link approaches it. The Ghost Ship itself appears at Diamond Steppe Island during a waning gibbous moon. A rare Blue ChuChu can be found if Link explores the second-to-last step.
An eight-eyed Big Octo can also be found off the southeastern coast of Diamond Steppe Island.
