This boss is a large, fire spurting, pulsing head made of solid iron, who enlists the help of huge stone hands in battle. Ironsider is impervious to Wario's punches, so the portly anti-hero must find some other way to damage it. The only way to hurt this boss is to beat up one of the hands, grab it, and fling it at the metal monstrosity. Repeat this procedure five times in order to fight Captain Skull.
