==Layout==
To reach the Cyclone Stone, the player has to destroy a large wall underwater with a [[Green Shell]], either by throwing the shell at the wall or by ramming into it (the latter will hurt [[Mario]]). Breaking open the wall will reveal a cave with a number of [[crate]]s and some [[Bat (Super Mario Galaxy)|bat]]s; [[Ground Pound]]ing the [[stump]] at the end will create a [[Launch Star]] that will take Mario to the Cyclone Stone.

The Cyclone Stone is a large, spiraling planet made out of stones, which are ever stationary or moving platforms. Many [[Thwomp]]s and [[Tox Box]]es move around the Cyclone Stone as well. The player has to avoid getting Mario squashed or sucked into the [[black hole]] underneath while navigating the Cyclone Stone. At the end of the Cyclone Stone is the [[Power Star]] trapped in a large [[Crystal (Super Mario Galaxy)|crystal]].
