Bob-ombs first come into play in the Mario Kart series in Mario Kart 64. They were not used as an Item, but are sprawled out across the track in multiplayer only. Also, in the Balloon Battle mode, if a player died in at leat 3-player, they were transformed into Bob-omb Cars that can ram into surviving players.
After being absent from Mario Kart: Super Circuit, they come back in Mario Kart: Double Dash!! as 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. Since then, a Bob-omb has been an Item in the succeeding games, open to every character.
The Bob-omb is an attack Item. It can be thrown ahead of the user's kart to try to knock over the opponent up ahead. If no one is near the Bob-omb, it will take about four seconds to detonate automatically. However, if a racer is near one, or if it thrown and lands directly on a racer, it will blow up right away. The blast radius is about 10 feet, and throws any kart up into the air (similar to a Blue Shell.) However, if a racer drives into the explosion, they will simply spin out.
The Bob-omb can also be dragged and dropped behind the kart. Using it as a shield against other Items such as a Green Shell or Red Shell is a bad idea (really bad idea) because it will blow it up right behind you. One strategy is that when you get a Bob-omb early in the race (when players are usually close together), drop it right behind you so multiple racers will be enveloped in the explosion.
The Bob-omb can be used as a defense against Blue Shells, but it is rare to have a Bob-omb is 1st. If you do, simply drop it behind you right when the Blue Shell is about to come down on you, and it will destroy the Item (extremely helpful technique!) The same goes for Red Shells and Green Shells. However, the bob-omb's explosion effects the mega mushrooms,resulting in a giant flipping kart.
