Be sure to drop one of these Super Mario Brothers Bath Bombs the next time you take a bath. At first glance, I thought these were tennis balls. Instead, the Bath Bombs are to be dropped in a tub of water - which causes them to fizz (think Alka-seltzer) and release a fragrant smell. However, the best part about these mysterious balls is that once they are fully dissolved, they release a Super Mario Brothers figurine. Each ball contains one and there are a total of six possible figures: Mario, Luigi, Fire Mario, Bowzer, Goomba, and Power Mushroom.
