New Super Mario Bros.: 7-1

World 7 is a cloud world. In this level, we'll find platforms on paths. Take the first platform to the right, then transfer to the higher platform. The platform will fall off its track and drop to the lower one so you can get the 1st Star Coin. It will go to the end of the line at the left and go back right, then fall into the void. Jump to the clouds to before it falls off. Here, you'll need to move quickly to get on the flying item block. Get on it before you reach the winding path of the platforms and don't hit it. It will take you over the void to a pipe. The pipe takes you to an area where you'll find lots of coins and ropes on gears. The ropes on gears will take you to the 2nd Star Coin and a green pipe back to the main level. There are more platforms on paths, but this time you'll have to contend with a respawning Fire Chomp. Fire Chomps have a tail of fire which represents how many flames they can shoot at you. If you don't stomp it before the tail runs out, it will explode. There are Red Coins in the area. Transfer to another platform which takes you to the pipe to the flag. To reach the 3rd Star Coin, take the platforms instead of taking a ride on the flying item block. Go up the pipe at the end of the path, then take the higher path to the 3rd Star Coin.
