World 1 (New Super Mario Bros.)



World 1 is the first world in New Super Mario Bros. It is a grassland-themed world with enemies such as Goombas, Koopa Troopas, and Cheep-Cheeps. This world also introduces the game's new power-ups, the Mega Mushroom, Mini Mushroom, and Blue Shell. Bowser Jr. and Bowser are fought here at the tower and the castle, respectively. There are eight levels in the world, with four along the standard path, one along a split path, and the Castle/Fortress level. There are five Toad Houses: two Red Toad Houses, one Orange Toad House, and two Green Toad Houses. In addition, when the player beats the game, a Blue Toad House appears, in which the player can buy and swap wallpapers for the touch screen while on the World Map. It has a total of ten exits.

A background based on World 1 appears during the first segment of the Mario World Dream Figure Skating routine in the Wii version of Mario & Sonic at the Olympic Winter Games.
