Grass Land

The first world of Super Mario Bros. 3. It has 6 levels, only one Hammer Bros., a fortress, and two Toad Houses. In level 3 and the fortress you can get two out of the three Warp Whistles in the game. Using both of them lets you take a short cut to world 8, Dark Land. Grass Land is the place where Larry Koopa, the youngest Koopaling is.
