World 3 is an ice-themed world owned by Lemmy Koopa in New Super Mario Bros. Wii.


World 3 is the third world in New Super Mario Bros. Wii. The world introduces the Penguin Suit and is the only world in the game to have a switch that can change the obstacles in the level (similar to a Switch Palace). On the map is an area with ice that has two Ice Bros. on it. If Mario and the gang are hit by them, they will endure a battle game where they will have to complete the Enemy Course. To access the second part of the level, you need to traverse a waterfall. This world has a cannon that leads to World 6.
