Chain Chomp Wheel

Chain Chomp Wheel (known as Chain Chomp Roulette in PAL regions) is a Battle Course in the game Mario Kart Wii for Wii. It takes place inside a casino's wheel with a gigantic Chomp rolling around and squashing racers in its path. This arena is located underwater, as a Mega Unagi and Cheep-Cheeps can be swimming outside by looking out the windows located on the walls of the wheel. As with Funky Stadium, the players start from off the map on Boost Pads and make an entrance into the map.

Layout
Because this Battle Course is based off of a wheel, it is round with a small incline, and is always moving. Boost Pads are located on the outer section of the wheel and in the very center of the wheel (which can be used to get Item Boxes located in the wheel's spinner.

Item Boxes are spread out around every few sections of the wheel and in the middle of a large star (which appears to act as the wheel's spinner), making it similar to the layout of Tart Top, a battle course from Mario Kart DS. Item boxes located in the center of the large star, albeit harder to obtain, will usually grant the player a Star item, although they can also occasionally give a Mushroom. As stated above, a Chomp rolls around the course, and anyone who runs in front of it is flattened. Any racers who run into the Chomp get knocked over as if they ran into a Bullet Bill.

Tournaments
A tournament took place on this battle course, where players had to collect one hundred coins, while avoiding the Incoming Chomp. It was restricted to Wii Wheel users, and the items that were used included Mushrooms, Mega Mushrooms, and Stars. This tournament was the second tournament of May 2009, and it was repeated again as the second tournament of May 2011, the first tournament of August 2012, and the second tournament of October 2013.
