Cirrus Heavens (or World 7) is the sixth, seventh counting Lunar Realm, world in Newer Super Mario Bros. DS. It's a pink, sky-themed world which introduces many new enemies, such as the Shy Guy and the Muncher. This world is represented by New Super Mario Bros. U-themed hills in the sky. Completing this world unlocks the eighth and the final world; Koopa Country.
Oddly enough, this world is unlocked from completing Moonview Glacier, not Lunar Realm despite being the seventh world of the game. It is unknown why Lunar Realm is designated as the sixth world, despite being a "secret world", and not Cirrus Heavens. This may be due to last minute changes.

- This is the only world in any Newer Super Mario Bros. game to force the player to take a secret exit. Upon completing Spiny Swings's normal exit, you'll get stuck at a dead end. This section resembles Illusion Forest from Super Mario World.
