Stone Cyclone Galaxy
Stone Cyclone Galaxy is a galaxy appearing in the game Super Mario Galaxy 2. It is located in World S. The galaxy consists of only one planet, which is essentially a replica of the Cyclone Stone from the Beach Bowl Galaxy in Super Mario Galaxy. Some differences include the addition of Octoombas, the removal of the last Thwomp, and the addition of multiple blue switches at different intervals around the planet. The switches are present as a result of the increased speed of the enemies, and are used to slow down the passage of time so as to make it easier for Mario to work his way around the planet unscathed. This is the only galaxy in the game to feature Tox Boxes. This is the only galaxy where the Cosmic Clones theme will play without a Prankster Comet in orbit.
The Cyclone Stone
The starting planet, made up mostly of stone, yet a few disappearing platforms appear later in the planet. As a result of the Cyclone below the platforms, all the platforms and stone enemies move faster than usual. If Mario makes even the smallest error, he will likely die and lose a life. Luckily for Mario, many 1-Up Mushrooms are found in the course, adding an extra life. Many blue switches are found throughout the planet, slowing down time and all the speedy objects. Common enemies here are Tox Boxes and Octoombas, and there is also a single Thwomp near the beginning. Silver Stars and Clocks can be found here on missions 1 and 2, respectively, which are used in order to unlock the star. The mission can be finished much more quickly if Mario performs a Long Jump from the pulpit near the end of the planet. The Stone Tube Planet in the Supermassive Galaxy bears a strong resemblance to the Cyclone Stone.
Green Star 1
The first Green Star is located near the halfway point of the course, very high up. In order to obtain this star, the player needs to perform a well-timed, well-positioned Triple Jump along with a Spin to grab the star. There is another way, which is to triple jump off the Tox Box rolling around at a fast pace. To complete this way, the player has to hit a ! switch to slow down time and to perfectly time a triple jump with the third jump being pushed off the Tox Box. This will easily ensure the player the star without having to spin.
Green Star 2
The last Green Star is located near the end of the course, hovering over the black hole below. In order to reach that distance far out, the player has to position Mario in just the right spot, and long jump to it. If the player is barely away from it, they will have the second chance to obtain it with a spin. If positioned wrong or the player does not spin, they will instantly be pulled into the Black Hole.
