Lunar Realm is the only secret world in Newer Super Mario Bros. DS. It takes place in outer space, where zero-gravity ensues. It is represented by the moon over a starry space.

Its tower boss is Bowser Jr. and its airship boss is Petey Piranha.


Lunar Realm takes place in space, where the only platforms are rocks and asteroids, similar to Starry Skies in Newer Super Mario Bros. Wii. Most levels have space physics, meaning the player jumps higher and falls slower, with the exceptions of Mt. Skydrop and Sledge Summits, which take place below in a mountainous terrain, and Runbow Road, which takes place on a stretch of rainbow-colored floating road akin to Rainbow Road of the Mario Kart series. Snailicorns, oddly enough, commonly inhabit the rocky terrain along with Amps.

Lunar Realm can only be accessed through using World 5-Cannon.png in Moonview Glacier, unlocked via The House of Stairs' secret exit. Completion of Thornspire Doomship grants access to Boomblast Badlands in Koopa Country.

6-2 Mt. Skydrop MtSkydrop.png The first mountain-themed level of Lunar Realm, making the player fall all the way from space. This, of course, only leads to Koopa Troopas and Boomerang Bros. that want the player gone.

6-7 Freeleap Galaxy FreeleapGalaxy.png An homage to Space Zone Area 2 from Super Mario Land 2: 6 Golden Coins where the player can jump freely while avoiding dangerous Stars.
6-Final.png Thornspire Doomship ThornspireDoomship.png A Skewer-filled airship where the player must carefully use their zero-gravity to jump over gaps. Petey Piranha is fought at the end.


  • Lunar Realm's space physics is an unused mechanic from the original New Super Mario Bros. It did not allow for wall jumps, which was part of the reason why Skawo decided to make this world secret.
