Grey Mountains (or World 9-9) is the ninth level of Special World in Newer Super Mario Bros. Wii. It is a snowy mountain-themed level featuring the Angry Sun and Mad Moon side by side.

Grey Mountains is unlocked by completing Purple Sewer. Completing it will unlock Black Clappers.


This level has a snowy mountain setting. It features the Angry Sun and the Mad Moon in one level, both a threat throughout the level. There are also ice blocks that contain coins inside, which can be melted by throwing fireballs at them. The level is fairly short.

Star Coins

  • Star Coin 1: After the second arrow sign should be a Star Coin that can be only reached by throwing a Koopa Troopa shell at it.
  • Star Coin 2: When at the frozen coins section, you'll need to melt the ice that contains the coins to access it. If you don't have a Fire Flower, you'll have to lure the Angry Sun to do it for you.
  • Star Coin 3: Shortly after, you'll need to be Super Mario to break the blocks blocking it. A Super Mushroom can be found in a Question Block.
