Rattle Buggy is an unlockable lightweight kart in Mario Kart: Double Dash!! It is mainly for Baby Luigi, being a green stroller-like kart, just like Baby Luigi's color. The kart is related to the Goo Goo Buggy, with only a couple of differences. This kart has slightly better acceleration than the Goo Goo Buggy, but has slightly worse acceleration. The weight stays the same as the Goo Goo Buggy. This kart can be unlocked by completing the 100cc Mushroom Cup in first place.
