New Super Mario Bros.: 8-4

Spiders are all over this level. A few of them will drop in every few seconds. The first Star Coin is on a high ledge. Either bounce off of a spider or run and jump to get it. There are rising stone platforms past the midpoint. The second Star Coin is over one of them. There's a Starman in one of the blocks so you can plow through the spiders. Low in the level are several stone platforms moving left and right. If you're Mini Mario, take the mini pipe below for the third Star Coin. The flag is nearby.
