A guide to completing World 7-2 in Super Mario Bros 1 for the Nintendo Entertainment System.

Explore World 7-2

World 7-2 is an underwater level. There are two coins on the ground after a short piece of coral, and there is Bloober to the right of the coins. If you up and to the right, there is another Bloober, as well as three coins.

After a taller coral, there are three coins on the ground, then three Bloobers.

Next, there is a pit with three coins, but remember that you will be pulled downward when you are above the pit, so you have to swim more quickly.

After some Bloobers and a bunch of Cheep-Cheeps, there are three coins beneath a platform with a tall coral on it.

If you go up and to the right, there are three coins above a small platform.

To the right of that, there is an area with a low ceiling, and a pit beneath it, with five coins.

To the right, there is an area with tall walls that contains six coins above a pit.

After that, you will encounter more enemies, then the exit pipe. After you exit, go up the stairs, make a running jump from the top to catch the goal pole, and you'll continue to World 7-3.
