Mt. Moon (PMU 7)

Mt. Moon is a dungeon reintroduced from PMU 6, placed in Archford east of Boggy Wastes. To access it, you must have Rock Smash. This dungeon has two paths and a secret miniboss; which path you continue on depends on which stairs you take at Floor 20. Keep your Rock Smash Pokémon for this dungeon as there is a maze on Floor 10 that requires it. This dungeon also has an alternate path that has different Pokémon.

Low Floors (1-15)
In these beginning floors, the scenery consists of cavern walls and random rock spikes poking from the ground. The ground is rocky, and there's a bit of darkness covering the place.

After Floor 10, there is a section which requires Rock Smash to get through. There is a key hidden in the bottom-left corner that you need to get to progress to floor 11. Apples are hidden in parts of this floor, as well as an Escape Orb at the floor's entrance in case you forgot your Rock Smasher.

Middle Floors (16-30)
The next few floors have a bit more grayish ground with small plants popping from it. The walls are more wavy, and the darkness still resides. Water starts appearing on these floors.

On these floors, there will be multiple sets of stairs. Only one of these stairs are real: The others are Pokémon spawner traps!

After floor 20, there will be a room that endlessly loops with many stairs. One stair has a blinking star next to it: this will bring you on the normal path through Mount Moon. The one left and up from where you spawn in brings you on the alternate route; it ends at floor 40, (you start at 21) and has different scenery and a different mix of the same Pokémon you'll see in the normal route. (If you're looking for Beldum, it's on this alternate route! Floors 31-40 at day or dawn.) Lastly, one of the stairs brings you to a room with two Clefable and some Clefairy who will attack you. Once you beat them, you will be brought back to the Floor 20 interlude. Please note that their staircase does not have a "Do you want to continue?" option and will immediately warp you in. All the other stairs at this interlude simply respawn you where you first came in.

After floor 30, there is a rest stop with a Kangaskhan statue.

Upper Floors (31-45)
On these floors, the grayish floor still resides, but the walls become a bit more purple, the darkness increases, more plants can be found popping from the ground, and water can be found in smaller groups.

There is a boss on floor 40.

There is a Sealed Chamber on floor 45. It can possibly contain Rose Silk, a rare silk for Fairy-types.

Highest Floors (46-60)
On these final floors, the scenery drastically changes. The walls are made of moon rock and the floor is extremely blue. There are green walls here and there and the water becomes darker. The darkness also increases once more.

There is a warp puzzle on floor 50. The warps you need to take, starting from the top left room, are Bottom Right, Bottom Right, Top Right, Bottom Left, Bottom Left.

Floors (21-40) (Alternate Route)
On Floor 20, you have the option to choose an alternate route. The walls are made of green rocks while the floor is a rigged rock floor. The stairs are flipped around as well.

The second boss of Mt. Moon is Deoxys. Deoxys is a Pokémon from space that does not value anything but the resources from the planet, as it leaves Deoxys in wonder.

Tips

 * Many Pokémon here use Attract and immobilization moves. A Shed Shell, genderless Pokémon, or Oblivious Pokémon may prove useful.


 * Bring a mobile scarf or a ghost. Items in the walls can sometimes be worth a good deal of money.
 * Embargo use is heavy here. You can't use items while under an Embargo, so watch out!
 * From 46F onward, some level 100 Pokémon start to appear. Metagross, Garchomp, Gengar and Blissey are occasionally at Level 100, while Slaking is always at Level 100 but in sleeping state.

Trivia

 * Deoxys used to drop an item called a Heart Pendant. When held, it would boost all team members HP by 75. It was removed for being too strong.
 * Enemy Pokémon received a significant level increase in this dungeon.
 * This is one of the best dungeon for levelling due to lv100 Blisseys
