World 1 (New Super Mario Bros. 2)

World 1 is the first world in the game New Super Mario Bros. 2. This world is a grass-themed world similar to many other Mario sidescrollers in the series. The map music here is the same one which was played in World 1 of New Super Mario Bros. Wii. This world is a compulsory world, meaning it is necessary to play before defeating Bowser in World 6, since this is the first world of the entire game.

There are 10 levels in this world, 7 are on the main path, 1 is an optional level, and the other 2 are the rainbow and cannon levels of the world. The 7 levels on the main path includes 5 normal levels, the Fortress and the Castle. Other than the 10 levels, there are also 4 Toad Houses in this world. This includes 2 red ones and 2 green ones. The boss fought at the castle is Roy Koopa. Completing that castle leads to World 2, while the cannon takes Mario to World Mushroom.
