'''Grumble Volcano''' is the last course in the [[Star Cup]] of ''[[Mario Kart Wii]]''. It takes place in a volcanic area covered with [[lava]], specifically the crater of a {{wp|supervolcano}} due to the lack of water around the volcanoes. The course features many jumps and moving platforms, as well as many sharp corners. At certain times, sections of the track will crumble away into the lava, making the road smaller and harder to drive around. The track's theme is very similar to that of [[World 8 (New Super Mario Bros.)|World 8]] in ''[[New Super Mario Bros.]]'' It reappears as a retro track in ''[[Mario Kart 8]]'' and ''[[Mario Kart 8 Deluxe]]'' as the third course in the [[Lightning Cup]].

The course takes place inside and around a volcano surrounded by lava. [[? Block]]s and [[Brick Block]]s are also found lodged in rocks as part of the scenery. At the beginning of the race, the track is straight. However, parts of this section will fall into the lava as the race progresses. [[Lava Geyser]]s may also occasionally spout in these areas. The track then enters the volcano and makes a turn, which will also crumble as the race continues, before approaching a moving platform, which allows the player to perform a [[Jump Boost|Trick]]. This leads into a tunnel with an upper route and lower route, both of which have [[Item Box]]es, and they both curve right and then left before leaving the volcano and approaching a pair of moving platforms, which also allow the player to perform tricks.

After the platforms, there are two roads. The right path leads to a [[ramp]] with a [[Dash Panel]] on it, while the left leads to a path with Item Boxes. After the roads meet, there are some [[Volcanic debris]] that act as obstacles. During this section, pieces of land will crumble and begin to sink into the lava. The path then splits again, with a Dash Panel and a ramp on the left and a normal path on the right. Once the paths meet, the player can encounter a small ramp.

After the ramp, the path splits again with the right path taking a lower route, and there is eventually a left turn to a pair of ramps. The left path instead leads to a higher route with a ramp with a Dash Panel. Both routes feature crumbling sections and [[Warp Pipe|pipe]]s with [[Fire Snake]]s, as well as falling Volcanic debris. The routes then meet and approach the finish line for the next lap. After passing the finish line, crumbling pieces of land are more common than they were in the first lap.

====Shortcuts====

[[File:Grumble Volcano shortcut.png|thumb|right|The rock glitch that allows lap completion]]

*Near the starting line is a rock that can be reached with a mushroom and performing a wheelie at the starting line or by performing a trick off the ramp before the finish line in a direction towards the rock. Once on the rock, the course can be completed by driving around the rock. The player must be careful as the rock will start to crumble at 53 seconds, and sink at 1:05. This glitch was removed in ''Mario Kart 8'' as it does not use a checkpoint system to determine if the lap will count like ''Mario Kart Wii'' does; besides that, the slopes of the rock are so steep that players will simply slide off.

*After the cave and past the moving platforms is a rock to the right side of the raised section of the track. In the ''Mario Kart Wii'' version, it is possible to drive on the rock formation by using a mushroom to reach the right side of the forked road. The rock will sink 1:35 seconds into the race, however, the player can still have Lakitu bring them to the right side of the fork with the use of a mushroom and a wheelie or well-timed hop if they hit the edge and fall into the lava.

*Near the end of the ''Mario Kart 8'' version of the course, at the right side of the fork, there is a pipe. Beside the pipe is a part that the player can do a trick off. In laps 1 and 2, there is a rock blocking the shortcut, but at the start of lap 3, it will sink into the lava, letting the player use it on lap 3. (This shortcut is also possible in ''[[Mario Kart Wii]]'' but there is no trickable ramp and it takes two [[Dash Mushroom|Mushroom]]s. It is possible with one, though it is extremely precise.)<ref>https://youtu.be/F2_aW8Iz1zs?t=449</ref>

[[File:2009-TournamentJune1.jpg|215px|thumb|right|The first tournament of June 2009]]

The first tournament of June 2009 took place at this course. Players competed in a time trial race, but they had to race the track backwards. To start the time trial, players received a set of [[Triple Mushrooms]]. This tournament was later repeated as the second tournament of May 2011, the second tournament of August 2012, and the first tournament of November 2013, though with a "Karts only" restriction.

Grumble Volcano returns as a retro course in ''[[Mario Kart 8]]'' and ''[[Mario Kart 8 Deluxe]]'' as the third track in the [[Lightning Cup]]. The clouds in the sky appear to be more orange than purple as opposed to in the original version. The volcano that the players drive through as well as the volcanoes in the background now have lava running down them. The course itself maintains its layout from the original, though both the first platform after the cave and the jump from the uphill left path now have [[Glide Ramp]]s. [[Volcanic debris]] falls more slowly than in the original course, the crumbling pieces of road crumble and sink much quicker (with an additional sinking piece of land added in the Volcanic Debris section of the course), and the course banner has been changed, now resembling a slightly deteriorated structure with torches added. The music also remains the same, similar to {{classic-link|3DS|DK Jungle}} and {{classic-link|3DS|Neo Bowser City}}, but has been given an echo effect.
