Bob-omb Car

From Mario Kart Racing Wiki

This is a car traveling the streets of Mushroom City in Mario Kart: Double Dash!!, Mushroom Bridge also from Double Dash!!, and Moonview Highway in Mario Kart Wii. They are Bob-ombs with wheels instead of feet. If they are hit, they will act like a typical bob-omb and make a huge explosion. They can be used as more effective, makeshift weapons, like using a green shell to make a bigger impact on those in the immediate area. �
