Big Steely is a big ball in Super Mario World that drops down in the final battle versus Bowser. It also damages Mario if he gets hit.

It appears again in Super Mario 64, where it does the same thing. In Super Mario 64 DS, only Wario can destroy these in his base form. If other characters are under the effect of a Super Mushroom, they can also destroy it.


  • It was found in the files for Super Mario Maker. It could have been a scrapped item for the game
