New Super Mario Bros.: 2-3

Time to underground! We take a pipe underground into a pipe maze. We walk to the right and wall-jump up for the first Star Coin. To progress, we have to ground pound the brown platforms with Star designs on them. There are bats in the area, so be careful. In the next part of the maze are one-way walls that fold down when you approach them, then close behind you. This can make navigating a little tricky, but just check the arrrows to see how they open. We go left, then down to a maze with a Piranha Plant, where the 2nd Star Coin is. To the right is a new area. We go down for an orange switch, which raises the water level then up for some coins. To the right is a new area with a giant Piranha Plant. If you have a Fire Flower, a few fireballs should take it out. We continue through the maze, going up, left, take the right path up, and then run down across the gap to the third Star Coin. There is a Piranha Plant in the lower left corner here. To the upper right is a red switch that makes blocks to go over the Piranha Plant. This path takes us to the main exit to 2-4. If we go back through this level and raise the water level and swim up, we find another orange switch that briefly raises the water level, allowing us to reach a higher part of the maze. This will lead us to teh Red Goal to 2-A.
