Bob-omb Blasting is one of the four mini-games found in the game Super Mario Galaxy along with Bubble Blowing, Manta Ray Surfing, and Star Ball Rolling. It appears in the Battlerock Galaxy and the Dreadnought Galaxy, and involves the use of multiple Bob-omb Dispensers. When Mario (or Luigi) arrives on the small planet that the mini-game takes place on, he is told by a furious Gearmo that people have been dumping trash in the ammo depot, which is supposed to be clean. Mario (or Luigi) therefore has to use Bob-ombs to blow up all the trash in under thirty seconds. The Bob-ombs take a full 10 seconds to explode, and the small yellow lights on the ground mark a good place to throw them.
