Shiverburn Galaxy is a galaxy appearing in the game Super Mario Galaxy 2, located in World 5. It is similar to the Freezeflame Galaxy from Super Mario Galaxy, as it revolves around the elements of fire and ice. Octoombas and Elite Octoombas are common enemies here. This galaxy uses the same music that is used in the Freezeflame Galaxy. Internally, the galaxy has the name "BeyondHellValley", likely named after an area in Japan named Hell Valley, which has hot springs and is surrounded by snow.
NOTE: Unless otherwise noted, all names are unofficial.
The planet is completely covered in lava and is U-shaped. A volcano is in the middle of the planet, which features platforms that slowly sink in the lava if the player stands on them. A moving platform takes the player to a Cloud Flower, which the player can use to get to the other Cloud Flower. Many Octoombas and Elite Octoombas try to hurt the player. Ring Beamers try to electrocute the player by shooting out an electric ring around it. There is a switch in the middle of a platform that instantly freezes the lava so the player can walk on the planet. Near the end of the planet, the player can either take the Launch Star to the Lava Planet or the pipe behind it to the Underground Ice Rink.
Underground Ice Rink
This area is only accessed during The Chimp's Ultimate Skating Challenge mission. It looks like the exact same ice rink from the Freezy Flake Galaxy's mission. There are 9 holes in the ground and The Chimp challenges Mario to get 600 points by defeating Gummits.
The planet is basically one huge ball of magma. There are rock platforms that float around in a circular manner to help the player get across. Many Octoombas are on the platforms, which get transported on them. If the player stays on the platforms for too long, they will be dragged into the lava walls. After the first half of the planet, there is an area with three coconuts, two Octoombas and a treasure chest. The player can open the chest with a coconut for a 1-Up Mushroom. The second half is generally the same as the first half except that there are now meteors falling down. There is another 1-Up Mushroom found at the end. The Launch Star will take the player to the Hot and Cold Planet. The Comet Medal is also near the Launch Star.
Hot and Cold Planet
The planet is a fusion of both ice and magma. When the player first lands, they should notice a long road covered in ice. However, meteors bombard the path and create molten fire puddles that will burn the player if they touch it. The player will need to navigate around the puddles while avoiding getting burnt, falling off, or being hit by the Elite Octoombas. At the end of the path, the player will need to defeat five Octopuses in order to proceed. At then next part, ice will drop from the sky and form a temporary path to the Launch Star. The player should quickly skate on this to Prince Pikante's Planet.
Prince Pikante's Planet
This is a generally small planet. It is completely covered in ice and is closely shaped like a peanut. There is a fence around it so the player will not fall off. Prince Pikante is fought on this planet. This area is also used as the only planet for the Octo-Army Icy Rainbow Romp, where many different Octoombas appear. But in this mission, there is no fence.
Green Star 1
The players will redo the Prince Pikante's Peppery Mood mission. When players freeze the lava, the volcano will freeze as well, stopping the lava from flowing. Players must climb to the top of the volcano using the Cloud Flower to grab the first Green Star.
Green Star 2
Players will redo the Prince Pikante's Peppery Mood mission. However, players should make their way all the way to the Lava Planet. At the end of the planet, there is a 1-Up Mushroom. To the right of the mushroom is the Green Star.
Green Star 3
Players should redo the Prince Pikante's Peppery Mood mission and need to have the Cloud Flower for this Green Star. Players need to make their way with the Cloud Flower to the Hot and Cold Planet. They should notice a cloud with a 1-Up Mushroom on it. Players need to create at least one cloud to get the Green Star located directly above it. If players do not have at least one cloud or the Cloud Mario/Luigi power-up, the Green Star cannot be obtained.
"Tree" Easter Egg
Three visible mysterious figures appear in the background of the galaxy if the player uses first-person view and looks up at the glacier cliffs. The three figures also appear in the background of the Pull Star Planet in Grandmaster Galaxy.
In the game's files, it is possible to see a fourth small figure. They are separate from the galaxy's background textures, and the filename of the graphics that depict them is "HellValleySkyTree". "BeyondHellValley" is the full background and sky model name, "Sky" probably refers to this part of the background and "Tree" refers to the figures.
The figures look similar to a mythical Japanese creature called a kodama. They are said to live in trees, or on tall mountains, and will supposedly curse a person if they attempt to cut one down.
