The Green Fire is a kart used by Luigi in Mario Kart: Double Dash‼. It can be unlocked by completing 50cc in Mushroom Cup. It is considered to be a "out of thee ordinary," karts due to its very low weight. Since it is a middle car, it can be used if one character is middle-weight and none of the characters are heavier. Diddy Kong's Barrel Train is heavier, despite Diddy Kong being smaller.
