Wii Grumble Volcano

Grumble Volcano is the last course in the Star Cup of Mario Kart Wii. It takes place in a volcanic area covered with lava. Drivers will have to jump over gaps in the track with lava beneath using the ramps. At the beginning of the race, players can cheat and boost onto a nearby rock, making the world record 19 seconds. From the second lap onward, parts of the track collapse and new gaps appear on the course. At the beginning of the track is a cave, followed by octagon platforms which move left and right. At several places, the track splits into a right and a left path, both of which drivers can take. Flame Bursts and Podoboos appear as obstacles. Giant ? Blocks appear in the background scenery.

Shortcuts
The only shortcut for this course is, most likely, the first Ultra Shortcut to be discovered for this game. A Mushroom is required. After the countdown, position yourself on the checkered area on the ground you start on, use a Mushroom, and this will proppell you over to the rock near the starting point. If it works, you'll find yourself on the rock. Drive around the rock, making sure to stay near the edge, do this three times, and you'll finish the race.
