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 level has significantly more Bill Blasters than the first two levels in World 5. The player must maneuver over large pits and pipes placed randomly around the level. The Hammer Bros. are an additional challenge to the level. Once the player makes it through the level, he or she must move 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. This level is identical in set-up as in World 2-2, but with more Bloopers. Similar to World 2-2, this level features Bloopers and Cheep Cheeps as enemies, and 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 and is the same in set-up as in World 2-3. Some bridges that the player must cross are broken into pieces. As usual, flying Cheep-Cheeps are found in this level; however, unlike World 2-3, Koopas are also found now.

World 7-4
World 7-4 is the last level of world 7, and thus it is a castle level. This level is similar to World 4-4 in the sense that the player must solve the maze in order 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.

Trivia

 * Worlds 7-2 and 7-3 are duplicates of Worlds 2-2 and 2-3, respectively, except that 7-2 has more bloobers, and 7-3 has Koopa Troopas in addition to the jumping Cheep Cheeps.
