? Switch


 * For the level, see Tower of the Wing Cap

The '''? Switch' appears exclusively in Super Mario 64 DS''. It appears in the secret level which is also titled ''? Switch'', which was formerly titled Tower of the Wing Cap. It serves mainly as a one-shot replacement to the three ! Switches. Upon pressing the ? Switch, all ? Blocks in the game will become solid (and therefore, usable). Whereas the three ! Switches only filled in ! Blocks of their respective color, the ? Switch filled in all ? Blocks.
