Skyward Stalk

Skyward Stalk, or Sparkling Waters-, is the secret course of Sparkling Waters in New Super Mario Bros. U. It is unlocked via the secret exit in Haunted Shipwreck and its completion skips Soda Jungle and unlocks Fuzzy Clifftop.

Layout
The course's main gimmick is a constantly growing beanstalk that spawns giant leaves and other particular plant life. The level is autoscrolling, so the player must always move verically as well.

 * Star Coin 2: On an orange bridge, covered by light clouds.
 * Star Coin 3: Near the end of the course, to the right side.

Trivia

 * The name of this level may be a reference to The Legend of Zelda: Skyward Sword, another game produced by Nintendo.
