Cirrus Heavens is the sixth world in Newer Super Mario Bros. DS, seventh if one is counting Lunar Realm. It's a pink sky-themed world which introduces many new enemies, such as the Shy Guy and the Muncher. It is represented by New Super Mario Bros. U-themed hills in the sky.
Cirrus Heavens is an area of pink clouds in the sky with blue and yellow hills in the background. It is partially inspired by Sakura Village in Newer Super Mario Bros. Wii, as its world map theme is shared, both of their skies are pink, and they both introduce the Shy Guy. Cloudbolt Chasm and Stormeye Stronghold take place during a thunder storm occupied by the Thunder Cloud. Unlike any other world, a secret exit is required to progress through Cirrus Heavens, as Spiny Swings leads back to Cloudbolt Chasm upon normal completion.
Cirrus Heavens can be accessed through completing Freezeflame Fortress in Moonview Glacier or through using World 3- in Dorrie's Island, unlocked via The House of Blocks's secret exit. Completion of Stormeye Stronghold grants access to Boomblast Badlands in Koopa Country.
