Mario Bros. Remix is the second level in campaign mode. It is a remix of the classic Super Mario Bros. 1-1 level. If played with four players, you can get the cool sun head if you win. It features the Mario levels, 1-1, castle 1-4, and underground 1-2. If you get through the fourth set of push blocks that resemble a pipe, it will take you to a shortcut. There is also a shortcut accesible if you manage to get on top of the long row of blocks near the cieling of the last section of the level.
