- This article is about blocks inscribed with a "!". For blocks inscribed with a "?", see ? Block. For the green and white item with a "!" on it, see Metal Box.
! Blocks appear on the Princess Peach's Castle stage in Super Smash Bros. Melee, whenever a block switch is pressed. When touched or attacked they produce one item, and then become brick blocks. The positioning of the ! Blocks depend on which block switch was pressed.
