Rattle Buggy

The Rattle Buggy is the kart of Baby Luigi in Mario Kart: Double Dash!!. It is a lightweight kart and can be unlocked by completing the Mushroom Cup in 100cc.

The Rattle Buggy features low speed, but has a high acceleration stat to back it up. This kart has the same speed and acceleration as the Toad Kart, and the two karts also have the exact same weight. However, the Koopa Dasher (another lightweight kart with similar stats) is slightly tougher than the two.

Trivia

 * The Booster Seat, from Mario Kart Wii may be an upgraded version of the Rattle Buggy.
