Booster Seat

The Baby Booster (also known as Booster Seat in North America) is a kart that appears in Mario Kart Wii. The kart is a baby stroller with an engine and 2 exhaust pipes in the back, a pair of headlamps on the front of the vehicle, and a roof that tends to open when the characters jump from the cab. The emblem is on the front and the back of the cab. Only small characters can drive this vehicle.

Stats
The Baby Booster is the slowest kart in the game, while it shows an average drift. On the other hand, the kart shows a high acceleration, off-road and mini-turbo. The Baby Booster also has the highest level of handling among karts. However, it gets knocked around a lot due to its low weight. It shares the same stats with the Nano Bike.

Trivia

 * The Baby Booster is one of six vehicles in Mario Kart Wii to go through a design change other than a palette-swap; the others being the Bowser Bike, Wario Bike, Twinkle Star, Torpedo, and Phantom. The case here is that the fringes of the Baby Booster's roof are absent when one of the Baby Mario Bros. is driving it.
 * The hub caps of Koopa Troopa's and Dry Bones's Baby Booster resemble a bird's eye view of their shells.
 * The Baby Booster has the same weight as the Bubble Bike.
