The Cloud 9 is a kart part that players can choose in Mario Kart 7. As its name implies, it is shaped like a cloud. It is the signature kart part for Lakitu, but it can also be used by any other character in the game.
The Cloud 9's acceleration and handling get a boost, while the speed and weight stats are hindered. It is tied with the Birthday Girl and Tiny Tug for having the lowest speed, and it's tied with the Birthday Girl and Koopa Clown for the highest handling of all kart bodies. Also, the Cloud 9 has the highest handling of any kart body that doesn't have a negative impact on the off-road stat.
In terms of its hidden stats, the Cloud 9 excels pretty well while underwater, and it offers one of the best sea handling stats of any kart body; a trait that it shares with the Tiny Tug. In fact, when compared to all the other kart bodies, the Cloud 9 has the highest stat total in the game.
The Cloud 9 makes a cameo appearance as a trophy in Super Smash Bros. for Nintendo 3DS, driven by Lakitu.
