Bubbly Clouds

A video game area that takes place on solid clouds in the sky. The characters may be seeking out a landmass or building in the sky, but they also might just be wandering through a huge field of solid clouds. Naturally, not falling to one's death is the biggest challenge of such an area, which can be made worse by the presence of annoying flying enemies. Fluffy Cloud Heaven is often this in video games. It's interesting to mention that already the first sidescrolling platformer - Jump Bug, released in 1981 - contained solid clouds.

Compare Levels Take Flight. Solid Clouds is the supertrope.
