Bullet Blaster

The Bullet Blaster is Bowser Jr.'s unlockable kart in Mario Kart: Double Dash!!. It is shaped like a Banzai 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 its acceleration, which is lower than the regular lightweight kart, but still better than a heavyweight. Its horn makes the sound of a noisemaker. The Bullet Blaster is unlocked by completing the Special Cup in 50cc.

Trivia

 * The Bullet Bike and Road Jetter in Mario Kart Wii and Mario Kart Arcade GP DX are similar to the Bullet Blaster.
 * The Bullet Blaster resembles the Banzai Bill seen on the Princess Peach's Castle stage in Super Smash Bros. Melee.
