Waluigi Racer is an unlockable kart in Mario Kart: Double Dash!!. It is the signature kart of Waluigi. Waluigi Racer is indigo and has an upside-down L. The player can unlock it by finishing 100ccFlower Cup in first place.
This kart has the same stats as Mario's Red Fire and the engine sounds the same as Waluigi's default partner's, Wario. Waluigi Racer is better than the Red Fire because it recovers faster than it when hit by a Green Shell or a Red Shell. It is also designed after Waluigi, with his signature colors and a design based on his nose and mustache.
