World 7 (Super Mario Bros.)

World 7 is the seventh world in Super Mario Bros. This is the second-to-last world in the game. This world has four different level types: One at ground, one underwater level, one set at seaside, and the final level being a castle as usual. Once again, this world is set during daytime.

World 7-1
World 7-1 is the first level of world 7, and has quite a few challenges within it. The level features Koopas, Buzzy Beetles, Bullet Bills, Piranha Plants, and Hammer Bros; However, this level features no Goombas. This player must maneuver over large pits and pipes placed randomly around the level. The Hammer Bros. are an additional challenge to the level, but once the player makes it through the level, the player moves on to the next one as usual.

World 7-2
World 7-2 is once again set underwater. It is also the last level set underwater. It features Bloopers and Cheep Cheeps as enemies, but one Piranha Plant appears at the end of the level once the player exits the pipe. The player must maneuver through mazes of bricks and coral as well as avoid the main enemies of the level. If the player is not equipped with the powers of a Fire Flower, than the player must simply avoid all enemies.

World 7-3
World 7-3 is set at seaside, but the player only walks across bridges. Some bridges are broken into pieces. Only Koopas and Cheep Cheeps are found in this level.

World 7-4
World 7-4 is the last level of world 7, thus it is a castle level. This level is exactly the same as World 4-4, only with more firebars. The player must solve the same puzzle the same way as in world 4 to confront the False Bowser. Once he is defeated, the player finds the last Mushroom Retainer in the game. That means that Princess Toadstool is in the next (and final) castle.
