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 resembles the Red Fire, but with green replacing red and Luigi's emblem in place of Mario's emblem.
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.
