How to Get to Level 2-A in Super Mario Bros DS
- 1). Enter level 2-3, and make your way through the stage until the half-way point. You see a low level of water flowing along the floor.
- 2). Jump to the left platform and step on the orange switch to raise the water's level. Go to the open room to the right, and swim straight up.
- 3). Continue swimming up when you reach the coin-filled room. Reach and activate another switch at the top of the room before the water level goes back down. This switch causes the water to go higher.
- 4). Swim upwards further until you are taken to the alternate exit. Exit the level through this path, and level 2-A is opened on the map.
