Dotted-Line Block

Dotted-Line Blocks (originally formatted as Dotted Line Blocks ) are transparent objects found in several Mario games such as Super Mario World, Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, Yoshi's Island DS, New Super Mario Bros. Wii and Super Mario Run. They represent that they can be solid when a switch is triggered rather than blocks appearing from nothing. In Super Mario World, they come in four colors and turn into ! Blocks once the player hits the ! Switch in the Switch Palace of the corresponding color. In Super Mario World 2: Yoshi's Island, Yoshi's Island DS, Yoshi's New Island, and Yoshi's Woolly World, after hitting a nearby ! Switch, the Dotted-Line Blocks will temporarily become ! Blocks and are able to be used as platforms. Dotted-Line Blocks in New Super Mario Bros. Wii can turn into and revert from red blocks after pressing the red ! Switches in World 3. In New Super Mario Bros. and Super Mario Run, red (yellow in Run) ! Switches can change Dotted-Line Blocks into red blocks for a limited time.

Transparent boxes similar to Dotted-Line Blocks appear in Super Mario 64 and its remake Super Mario 64 DS, where they turn solid and are able to be used after hitting the ! or ? Switches in the Tower of the Wing Cap in both versions, and in the N64 version only, Vanish Cap Under the Moat, and Cavern of the Metal Cap.
