World 7-3 (Super Mario Bros.)
World 7-3's layout is similar to World 2-3's, but with added Koopa Troopas and Koopa Paratroopas that are placed on the various bridges, along with additional Cheep-cheeps. The level is made up of long bridges the player must run and jump across while avoiding an endless array of jumping Cheep-cheeps. If the player is running, the Cheep-cheeps will usually jump up behind the player, though if the player is walking, they will jump from the front and there is a good chance of the player getting hit. The player also needs to jump across some small floating platforms that are placed in the second half of the stage. In the only ? Block near the center of the level is a power-up. If the player reaches the stone steps at the end, the Cheep-cheeps will stop jumping from below.
