New Super Mario Bros. Wii 9-6 -- Lava Acrobatics

After finishing World 8, I do not need any more lava. This level has platforms going in and out of the lava. You need to time your jumps well to make it through. You can stand on the platforms, jump when they go in, and land on them when they come out without taking any damage. The 1st Star Coin is hidden in the rock just past the 2nd circling platform, which dives into the lava. The 2nd Star Coin is in between 2 rocks, in a series of lava pillars. I wall-jumped to get it. You also have to dodge the Fire Chomp that will appear here and follow you around. The 3rd Star Coin is underneath the pipe to the goal. There is a small platform diving into the lava, but a lava pillar will appear periodically in front of it. I just used a Propeller Suit to get it and reached the goal. This took me 30 tries.
