Bullet Blaster

The Bullet Blaster is Bowser Jr.'s unlockable kart in Mario Kart: Double Dash!!. It is shaped like a Bullet Bill, and like Diddy Kong's Barrel Train, is one of the fastest lightweight karts in the game. Unfortunately, this kart is also the lightest kart in the game, and can be knocked around by any other kart of any weight class. Another one of the kart's good stats is it's acceleration, which is lower than the regular lightweight kart, but still better than a heavyweight. The Bullet Blaster is unlocked by completing the Special Cup in 50cc.
