Bouncy Cloud Boomerangs
From the Super Mario Wiki
Bouncy Cloud Boomerangs, or Meringue Clouds-4, is the fourth course of Meringue Clouds in New Super Mario Bros. U. It is unlocked via completion of Spinning Spirit House, and its own completion unlocks another pathway to Snaking above Mist Valley.
Unlike most of the Meringue Clouds levels, the background has pinkish-peach clouds instead of white clouds. The main gimmicks of this level are Bouncy Clouds. They make the player bounce very high upon contact. Boomerang Bros also appear in great numbers here.
