World 7-1 (Super Mario Bros.)
World 7-1 is the first level of World 7 in Super Mario Bros. and the twenty-fifth level overall in said game. In Super Mario Bros. and Super Mario Bros. Deluxe, the level has a simple grassland palette, but in Super Mario All-Stars, the ground is covered in snow, though does not affect the player's movement.
World 7-1 is lined with Turtle Cannons and pipes with Piranha Plants. In the left block of the row of Brick Blocks above the second Turtle Cannon is a power-up, and the block directly right of the floating Turtle Cannon is a Coin Block. Across the gap and after the first pipe are two Hammer Brothers that jump between two rows of Brick Blocks. Above the left of the next pipe is a Hidden Block with a 1 up Mushroom, and said pipe leads to an underground chamber with coins, which exits out of the second pipe to the right. After another duo of Hammer Brothers is a jumping board that can help the player reach a high block with a power-up, followed by two flights of Hard Block stairs with a Buzzy Beetle walking down the second one before the flagpole.
