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 and ice. The map music is the same one which was used in World 3 of New Super Mario Bros. Wii. This world is unlocked when a player completes World 3-Castle. This is also an optional world as the player can choose to go to World Flower instead. There are twelve levels and five Toad Houses in this world, making it the longest world in 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. World 4 is the only world with Warp Pipes on its map. Some levels in this world have a jagged mountainous background that is similar to those found in several levels in Super Mario World. The boss of this world is Morton Koopa Jr., who is fought at the castle level.

Several enemies are first encountered in World 4:

• Mini Goombas
• Chunks of ice (normal and big)
• Spiked balls
• Large spiked balls
• Big Boos
• Big Bone Piranha Plants
• Amps
• Big Fuzzies
• Fire Bars
