Koopa Country is the seventh and final world in Newer Super Mario Bros. DS, eighth if one is counting Lunar Realm. It is a Bowser-owned land divided into two parts, the first being a dark deserted wasteland and the second being a lava-filled area. It is represented by a volcano over a red sky.

Despite being an even-numbered world, Koopa Country has no Airship level. Its tower boss is Bowser Jr. and its final castle bosses are Bowser and Bowser Jr. Monty Tank is fought within Ironclad Battalion.


Koopa Country is divided into two distinct parts as with the original World 8 from New Super Mario Bros. The first part before Basalt Bay takes place in a barren desert-themed wasteland. Cacti and quicksand are commonly found throughout. After Ironclad Battalion, Koopa Country turns into a traditional lava theme. Dry Bones and Podoboos become commonplace. At the end is Bowser's very own castle.

Koopa Country can be accessed through three ways, by completing Stormeye Stronghold in Cirrus Heavens, completing Thornspire Doomship in Lunar Realm, or using World 4-Cannon.png in Pumpkin Boneyard, unlocked via The House of Doors's secret exit. Completing Bowser's Castle, finding all 96 exits in the game, obtaining all 240 Star Coins, and the purchase of all Star Coin Signs grant access to Special House in Goldleaf Plains, granting no new levels, signaling the end of Newer Super Mario Bros. DS.
