Bob-ombs have been used as items in several Mario sports titles. In Mario Kart: Double Dash!! they were Wario and Waluigi's special item. Petey Piranha and King Boo also can possess this item because they have the ability to get any special.
In other Mario Kart games, it is a normal item which usually 4th place racers get. When thrown, the Bob-bomb stand still for a moment before exploding, throwing any nearby drivers into the air. It will explode immediately if a racer drives right into it. Even the person who threw it will be tossed up if they're close enough. In both Mario Kart 7 and Mario Kart 8, the Bob-omb will follow nearby racers when thrown.
