- The Gauntlet - Here, the Mario brothers can fight X Bosses, which are optional bosses that are bosses they have fought before, but twice as tough. They must be a specific level in order to fight a boss here.
- Cholesteroad - Here, Mario and Luigi use the Special Attacks they have learned to fight the same enemies until the player messes up.
There is also a block that works the same way a Rally Block does here. If it is hit 99 times in a row, the player's coins will automatically be doubled.
