Tropical Refresher

Tropical Refresher, or Sparkling Waters-2, is the second course of Sparkling Waters in New Super Mario Bros. U. It is unlocked via completion of Waterspout Beach, and its own completion unlocks a green Toad House and Giant Skewer Tower.

Layout
The course contains various pipes that either shoot out coins or shoot currents that push the player back. The most common enemies are Big Cheep Cheeps, Bloopers and Big Urchins.

Star Coins

 * Star Coin 2: Between two Big Urchins is a hidden wall with a ? Switch in it. The player should hit it to make the second Star Coin fall.
