World A-1

The player starts off at a place with 8 ? Blocks with Koopa-Troopas on them, and a Koopa Paratroopa on the ground. If the player jumps in between the gap of the second row of ? Blocks, a power-up will pop out of it. Now the player will see Brick Blocks with 3 Koopa-Troopas walking on them. If the player were to hit the Brick Block on the topmost right, a vine will pop out of it, leading to a Coin Heaven room. The player will see 2 pipes with Red Piranha Plants in them. Also, the brick block floating high in the air contains a 1-Up. Now, the player will see many ? Blocks, along with two Hammer Bro.s trying to attack the player. One of the ? Blocks contain a Poison Mushroom, while the others contain coins. Now the player will see rows of Brick Blocks with Koopa-Troopas walking on them. If the player kicks the Red Koopa Troopa at the top first, and runs along with it so it stays at the screen, they shall get a 1-Up. Here is another pipe with a Red Piranha Plant in it, along with a couple more ? Blocks with coins and another Poison Mushroom. Hammer Bros. are also seen in this area, along with more Red Piranha Plants. If the player goes in the on atop the Brick Blocks, they will be in a Bonus Room. A Koopa Paratroopa will appear, and the player will see coins along with a pipe and Brick Blocks, that are only accesible if the player took the Bonus Room route. The player will see two pipes facing each other here, and both of them have Red Piranha Plants in them. Some Koopa Troopas can be seen here, and two brick blocks, the bottom one containing a multiple coin block, along with a Trampoline. The player will see blocks with Koopa Troopas walking on them, along with a platform that will fall if the player is standing on it. The flagpole can be seen here.
