Editing Wii Grumble Volcano

After the platforms, racers have the option to go right and go off a [[Dash Panel|dash panel]] ramp, or go left and drop down onto a lower part of the track, where there is another pair of Item Boxes. Both choices involve a slight turn to the left. Afterwards racers will begin to encounter [[volcanic debris]], which is launched onto the course from another volcano far in the distance; hitting volcanic debris will make racers spin out. There is then a gradual U-turn to the right, with dead trees on both sides of the track and more volcanic debris on the track. Along the first half of the turn on the outside is an elevated path that once again ends in a dash panel ramp. After the turn, racers go off another simple ramp and reach one more split path, with a slight left turn or a slight right turn; at the start of each path is one last item set. If racers go left, there is a turn to the right followed by a very brief straight and one last dash panel ramp. If racers go right, there is a left turn, a simple ramp, and a right turn. Along both paths, racers must pass several [[Warp Pipe|pipe]]s which [[Fire Snake]]s occasionally jump onto the track from. Hitting one will make racers spin out. Where the two paths join, there is one last simple ramp followed by the finish line.

[[List of Mario Kart Wii tournaments#Tournaments|June 2009's first tournament]] required players to complete a Time Trial in reverse on Grumble Volcano. There are several ramps added to make this possible, though there are also some barriers and extra Lava Geysers added. Players start the Time Trial with a set of [[Triple Mushrooms]]. Vehicles are restricted to karts only. The tournament was later repeated as the second tournament of May 2011, the second tournament of August 2012, and the first tournament of November 2013.

Grumble Volcano makes its classic course debut in ''[[Mario Kart 8]]'' and ''[[Mario Kart 8 Deluxe]]'' as the third race of the [[Lightning Cup]]. Its layout is mostly retained but has several notable changes. There are two [[Glide Ramp|glide ramp]]s, one on the second stone platform and one at the end of the left path at the end of the track, replacing its dash panel ramp. An additional chunk of the track right after the first dash panel ramp sinks into the lava. [[Volcanic debris]] falls more slowly than in the original course, and chunks of the course start shaking and sinking sooner into the race. The course geometry has also been modified along the right path at the end of the track, enabling a new shortcut that functions similarly to the shortcut that skipped the final turn in the original iteration. In this case, it cuts off the turn but is blocked by a large rock formation until lap 3. Lastly, most Item Boxes have been removed, with exception of the first and second full item sets. Instead, there is a set along the gradual right U-turn next to the dash panel ramp. Double Item Boxes also appear at the second and last item sets in ''Mario Kart 8 Deluxe''. Visually, 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 starting banner has been changed, now resembling a slightly deteriorated structure with torches added and the modern ''Mario Kart'' logo. Similar to {{classic-link|Wii|Mushroom Gorge}}, {{classic-link|3DS|Neo Bowser City}}, {{classic-link|3DS|DK Jungle}}, and the stadium and museum portions of {{classic-link|Tour|Madrid Drive}}, the music remains mostly unchanged, but the guitar and sitar have been updated and the mastering has been tweaked.
