World 5 (New Super Mario Bros. 2)

World 5 is the fifth normal world in New Super Mario Bros. 2. It has a sky and mountain theme, and the levels are either in the sky or on a mountain. The map music is a remix of the World 7 music from New Super Mario Bros. Wii. This world is unlocked once the player completes World 4-Castle or World Flower-Castle. The boss of this world is Ludwig von Koopa.

To access this level, the timer must end with the two digits '55' (that is, 'x55', where 'x' can be any number) when the player reaches the flagpole of any World 5 level. Once the level is completed, it can be accessed again by satisfying the above condition once more.

Mario is launched onto a moving platform, which passes through two waves of Coins arranged in arch formations, a Coin Roulette Block, another wave of Coin arches, then a large Coin Roulette Block. Two more waves of Coins fly by as the platform reaches the right edge of the screen, marking the end of the level.
