Snaking Above Mist Valley is the eighth level of Meringue Clouds in New Super Mario Bros. U. It is unlocked via completion of Spinning Spirit House, Bouncy Cloud Boomerangs, or A Quick Dip in the Sky, and its own completion unlocks Ludwig's Clockwork Castle.
Like Bouncy Cloud Boomerangs, the clouds are pinkish-peach instead of white. The level begins near a Snake Block platform and a Foo on a row of ? Blocks. The Snake Block acts as the main part of the ground in the section, and the level immediately begins to autoscroll when it is touched. Paratroopas and Foos are encountered in the area. A P Switch is found, and a section of ground follows. More Paratroopas and Foos then follow. A Pipe Cannon leads the player to the Checkpoint Flag. Another Snake Block is found, which continues above a pit. A Paratroopa, a Fire Bro, and a Foo can be found. A Green Ring is located beneath a section of ground. Another Foo is found, along with a section with Paratroopas and clouds that cover portions of the level. Fire Bros and Foos are found near the end of the area, where a Warp Pipe is found. The Goal Pole is found.
- Star Coin 1: The player should activate a P Switch to reveal Blue Coins and turn the Brick Blocks barricading the first Star Coin into Coins.
- Star Coin 2: The second Star Coin is found in plain sight. The Snake Blocks or Super Acorn/Peachette can help the player reach it.
- Star Coin 3: In the second area, the third Star Coin is in plain sight. However, the Snake Block goes above it. The player should either use the Super Acorn or Peachette, or throw a Koopa Shell to collect it for the player.
