Waddlewing's Nest

Waddlewing's Nest, or Rock-Candy Mines-3, is the third course of Rock-Candy Mines in New Super Mario Bros. U. It is unlocked via completion of Grinding-Stone Tower or Shifting-Floor Cave, and its own completion opens the path to a red Exclamation Mark Switch, a spot where a Bubble Baby Yoshi resides, a green Toad House, and Walking Piranha Plants!.

Layout
As the title implies, this course houses Waddlewings and possibly could be the birthplace of the species. Piranha Plants in pipes and Chain Chomps are also present in this course.
