Domino block

Wario about to use a button to break domino blocks.

Domino blocks are blocks appearing in Wario Land 4. They only appear in the level Domino Row, and can be found blocking the way to certain paths or jewel pieces. Unlike regular blocks, they cannot be destroyed by Wario's moves. Instead, the player must press a button to break the domino blocks apart.

With the exception of the first button, Wario must race a row of dominoes to each button. If the dominos reach the button first, the corresponding domino blocks can't be destroyed during that same play-through of the level.
