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 heavier than the two.

Strangely, the Rattle Buggy actually accelerates better than the Goo-Goo Buggy, which is a five star accelerator. Its acceleration is also tied with that of the Boo Pipes.
