New Super Mario Bros./World 6

World 6 is one of two worlds that are unlocked after completing World 5, and is the default world if one completes World 5 normally. While it is themed around a mountain range and stone, it features environments from previous worlds, such as deserts, beaches, jungles and snowy lands. There are 5 Toad Houses in total, each requiring Star Coins to access. There are no secret exits in this World, but alternate stages can be unlocked using Star Coins.
