Dragoneel's Undersea Grotto

Dragoneel's Undersea Grotto, or Sparkling Waters-5, is the fifth course of Sparkling Waters in New Super Mario Bros. U. It is unlocked via completion of Above the Cheep Cheep Seas or Urchin Shoals, and its own completion unlocks Larry's Torpedo Castle.

Layout
This course includes Eep-Cheeps and quicksand. This course also introduces Dragoneels, gigantic sea serpents that follow the closest player to a degree.

Star Coins

 * Star Coin 1: In plain sight, with coins circling it.
 * Star Coin 2: Between two groups of Brick Blocks.
 * Star Coin 3: Almost submerged in quicksand is a Warp Pipe that leads to the area with the final Star Coin.

Enemies

 * Dragoneels
 * Dragoneel (purple)
 * Eep-Cheeps

Trivia

 * If one were to use a Baby Yoshi, whether balloon or bubble, and continuously press the ZR or ZL button, the player can zoom through the course without the worries of the Dragoneels.
