The Snot Bomb is one of Wario's special items in Mario Kart Arcade GP and Mario Kart Arcade GP 2.
Upon using the Snot Bomb, the user will flick a small black ball out of their nose. This ball travels in a straight line, and any racers who get hit by it will lose speed. The Snot Bomb can be fired either forwards or backwards, depending on whether the player holds down the accelerator when firing the item.
The Snot Bomb is one of the few items in Mario Kart Arcade GP and Mario Kart Arcade GP 2 to have a unique animation for the racer using it. Others include the Conga, Tongue, and Giant Banana.
