New Super Mario Bros. U: Peach's Castle-4 -- Firefall Cliffs

More meteors rain down in this automatic sidescrolling level. Mario must climb up the rock walls as quickly as possible to avoid the meteors. We get the Acorn Mushroom in this level. The first Star Coin is out of reach, so use the POW Block to make it drop out of the sky. There's a Starman just before the midpoint, and you can get a short chain going, as an item block has one ahead. Next, you'll have to climb up the rock walls. You'll find the second Star Coin here, within reach. The path will briefly split so you can reach a Green Ring below. The coins will appear on the path above, which is where you should go. Avoid the lava. You'll jump and climb up some more rocks while dodging meteors, and the path will split ahead, heading towards the top. The third Star Coin is on the path on the right, which is more difficult as the path is only wide enough for a meteor. Use the alcoves and climb quickly to avoid taking damage. The third Star Coin will be at the top, with the pipe to the flagpole. This opens the path to the castle.
