'''World 4''' is the fourth normal world appearing in ''[[New Super Mario Bros. 2]]''. It is a snow-based world, and the levels are made up of snow or ice. The map music is the same one which was used in [[World 3 (New Super Mario Bros. Wii)|World 3]] of ''[[New Super Mario Bros. Wii]]''. This world is unlocked when a player completes [[World 3-Castle (New Super Mario Bros. 2)|World 3-Castle]]. This is also an optional world as the player can choose to go to [[World Flower (New Super Mario Bros. 2)|World Flower]] instead.

There are twelve levels and five [[Toad House]]s in this world, making it the longest world in ''New Super Mario Bros. 2'' ([[World 3 (New Super Mario Bros. 2)|World 3]] has the same amount of levels, but two less Toad Houses). This world has a total of fourteen exits. Of the twelve levels, eight levels are on the main path, which includes five normal levels, a [[Ghost House]], and the [[Fortress]] and [[Castle]]. Of the remaining four levels, one is the [[Rainbow Course]], one is a level requiring payment of Star Coins and the other two are secret levels. Of the five Toad Houses, two are red, two are green and one is yellow. The boss of this world is [[Morton Koopa Jr.]], who is fought at the castle level.
