New Super Mario Bros.: 5-2

This level takes place underground. This level has Spike Buzzies crawling all over platforms and they're not easy to get rid of, so we have to dodge them. Making life more difficult are the bats you'll find periodically hanging from the ceiling. You'll also come across Piranha Plants in some of the pipes. You'll need to be at least Super Mario to get the first Star Coin by breaking brick blocks. Along the way, you'll find a couple of springs. The first spring will be near a yellow pipe overhead. Spring into the pipe and you'll go outside and find a Moneybag disguised as a coin. Follow it to the end of the area and bounce off it to reach the second Star Coin. The third Star Coin floats between two platforms where Spike Buzzies crawl. Time your jump from the spring to get it. Near the third Star Coin, the path splits. If you take the top route, you have to deal with Spike Buzzies and Piranha Plants. The bottom route has lots of bats. There are more bats and Spike Buzzies up until the end.
