Rattle Buggy

The Rattle Buggy is Baby Luigi's kart 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 in-game 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 heavier than the two.

In terms of its actual stats, the Rattle Buggy's speed is tied with the Koopa Dasher and Boo Pipes. Its acceleration is also tied with that of the Goo-Goo Buggy and Toadette Kart.
