The Koopa Clown is an unlockable kart part in Mario Kart 7 and Mario Kart 8 Deluxe, based upon Bowser's Koopa Clown Car. It boosts handling, but lowers acceleration and off-road slightly. It should also be noted that the Koopa Clown is tied with the Birthday Girl and Cloud 9 for having the highest handling of all kart bodies, and it has the highest handling of any kart body that doesn't have a negative impact on the Speed stat.
In terms of its hidden stats, the Koopa Clown offers one of the strongest mini-turbo boosts in the game; a trait that it shares with the Barrel Train and Bumble V kart bodies. Its engine noise is similar to that of the Tyrant, Hurricane, Rambi Rider, Wildlife, Brute and Dragonfly from Mario Kart DS and also shares it with the Cact-X.
CPU Bowser can occasionally be seen driving in this body.
Although it does not appear in the original Mario Kart 8, the kart reappears in Mario Kart 8 Deluxe as an unlockable kart body, and it is redesigned to appear smaller. The exhaust pipes are shorter and it is equipped with a pair of propellers that open up on gliders and anti-gravity segments. The tips of the propellers also have a secondary color. Much like the Landship, the kart has different palette colors for the Koopalings, which match the colors of the Koopa Clown Cars they use in Super Smash Bros. for Nintendo 3DS / Wii U. For other characters, it uses the default green color. Its engine sound is shared with the Biddybuggy. CPU Bowser, Bowser Jr. and the Koopalings occasionally use this body during races. It gives off a small boost to weight, water speed, handling, water handling, and the highest boost to traction, while speed, acceleration, and mini-turbo are hindered.
The Koopa Clown returns in Mario Kart Tour. It appears to be equipped with the Standard tires, based on their appearance in Mario Kart 8 and Mario Kart 8 Deluxe. Unlike in Mario Kart 8 Deluxe, the rim of the Koopa Clown doesn't change color no matter which of the Koopalings is driving it.
