World 2 (Super Mario Bros. 2 USA)

World 2 is the second world of the games Doki Doki Panic and Super Mario Bros. 2. The world has a desert and pyramid theme to it, which is later revisited in World 6. It is in this world that the player meets for the first time the Cobrat, Pokey, and Panser enemies, as well as their first boss fight against the red, egg and fireball-spitting version of Birdo. The main boss of the world, fought at the end of World 2-3, is Tryclyde, the three-headed snake.

World 2-1
This level is divided into two segments. In the first, the chosen character has to walk through the sandy and silvester desert as he or she avoids traps like quicksand and new enemies, such as Pokey cacti, Cobrat snakes, and numerous Pansers. After that, a pyramid is explored; the character has to dig through sand until reaching the bottom. Birdo is fought in a chamber full of chasms, so caution is the key in the battle.

World 2-2
Very similar to the first level; outside exploration is first, followed by an underground cavern. There is also an additional cavern where an extra life can be gained; and Birdo shoots both fire and eggs for the first time (although mushroom blocks can be used instead to battle her).

World 2-3
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 magic 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, then dig to the bottom to find a key that open the door showing the path that leads to the world's boss, Tryclyde.
