Luigi Block

The Mario Block is a type of block that appears in the Wii U title, New Super Luigi U. In this game, the block appears at the beginning of levels, but only after the game is completed. Hitting the block allows the player to switch to the physics of New Super Mario Bros. U, with lower jumps and better traction. It will not, however, affect Nabbit, and does not appear when you are playing as him on your own.
