They appear only in the second phase of the final battle with [[Bowser]] in ''Super Mario World'' and [[Super Mario World: Super Mario Advance 2|its reissue]]. Bowser drops Big Steelies from his [[Koopa Clown Car]], and [[Mario]] or [[Luigi]] can [[jump]] over them to avoid getting hit. Mario or Luigi can also [[Spin Jump|spin-jump]] on them without getting hurt. A Big Steely can be destroyed if Mario or Luigi uses his sliding cape attack against it using a [[Cape Feather]]; however, a [[glitch]]ed sprite is displayed if this happens. In the reissue, the game timer stops counting down when a Big Steely appears and resumes when it rolls off the screen.
