World 2-3 (Super Mario Bros. 2)
If the player plays as Luigi, there is a cave right at the beginning of the level, that only Luigi can jump high enough to get to, that leads to a Magical Potion and a bunch of coins. The rest of the level is not too different from its two predecessors. The difference is that, once inside the pyramid, the chosen character must first fall through a hole. After landing on the first ledge, there is a Magical Potion that leads the player to a Yoshi Egg in Super Mario Advance. The player should then dig to the bottom to find a key that open the door showing the path that leads to the world's boss, Tryclyde.
