Mt. Moon (MM) is a dungeon reintroduced from PMU 6, placed northwest of Archford, east of Boggy Wastes. To access Mt. Moon you must have Rock Smash unless it has been completed before, in which you can use the unblocked shortcut to the entrance. While the dungeon has 60 floors, it also has two paths and a secret miniboss; which path you continue on depends on which stairs you take at Floor 20. The alternate path of this dungeon includes no bosses and has 40 floors.

Normal Path
After Floor 10, there is a section which requires Rock Smash to get through. Rock Smash is only needed if you haven't completed Mt. Moon, otherwise you can use the warp on the left to warp straight to the locked doors. There is a 
Lunar Key hidden in the bottom-left corner that you need to get to open the locked doors and progress onto Floor 11 and will automatically disappear from the bag then. There's an 
Escape Orb at the floor's entrance in case you do not have Rock Smash. Two more Escape Orbs, two apples and two Leppa Berries are additionally hidden in parts of this floor.
After Floor 20, there will be a room that endlessly loops with many stairs. One staircase has a blinking star next to it; this will bring you on the normal path through Mt. Moon. The one left and up from where you spawn in brings you on the alternate path; 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 path. Lastly, one of the stairs brings you to the miniboss with Clefable and Clefairy. 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 in the Pixiefall Arete.
After Floor 30, there is a midpoint with a Kangaskhan Storage.
There is a warp puzzle after Floor 50. The warps you need to take, starting from the top left room. It can be completed using the following route:
- bottom-right
- bottom-right
- top-right
- bottom-left
- bottom-left
On Floor 45 is a sealed chamber.
Box items:
Rose Silk- Golden Apple
- Max Revive
- Big Nugget
Alternate Path
Bosses
Clefairy and Clefable
There is a secret miniboss one can fight, accessible in the interlude after Floor 20. The lowest right staircase will take you to a room with many Clefairy and two Clefable. Once you beat them, you will be brought back to the Floor 20 interlude. Neither Clefable or any of the Clefairy drop anything when defeated.
Dialogue:
- Clefable: All hail the Meteorite!
- Clefable: All praise it's worth.
- Clefable: We are the children of the Meteorite. We are its beautiful dream.
- Clefable: To it we fully pledge our souls. From it we came, and to it we go.
- [Player Name]: ...?
- Clefable: ...Hm! Intruders have cast eyes upon our precious meteorite? Get 'em!
Team Charm
After Floor 40, there is a midboss. It is a reference to Team Charm from Pokémon Mystery Dungeon: Explorers of Time/Darkness/Sky (Medicham, Gardevoir, and Lopunny), with an additional Wobbuffet.
They know the following moves:
- Gardevoir: Encore, Moonblast, Psychic, Shadow Ball
- Lopunny: Circle Throw, Dizzy Punch, High Jump Kick, Magic Coat
- Medicham: Drain Punch, Fire Punch, Ice Punch, Thunder Punch
- Wobbuffet: Counter, Mirror Coat, Safeguard
Boss drop:
- 1 Big Mushroom (Wobbuffet)
- 1 Mushroom (Medicham, Gardevoir, Lopunny)
Dialogue:
- (...)
- Wobbuffet: So, for our master plan, you will have to reach the top of the mountain.
- Wobbuffet: Once you are there, retrieve the remain of the meteorite that crashed.
- Wobbuffet: If you fail I wi-
- Wobbuffet: Oh wob?
- Medicham: Ohoho, an intruder?
- Lopunny: An intruder? In OUR base?
- Gardevoir: It's more likely than you think!
- Medicham: Who dares disturb The Charms' base?!
- Gardevoir: A nobody, that's who!
- Lopunny: Is it beat up time?
- Trio: Beat up! Beat up! Beat up!
- (...)
- Wobbuffet: Wob.
- Medicham: Ah, sorry boss.
- Lopunny: So, what's the plan, boss?
- Wobbuffet: Wobba!
- Gardevoir: ... A brilliant plan, I must say!
- Medicham: ... I agree~
- Lopunny: Boom!
- Lopunny: Let's go, girls!
- Wobbuffet: Wob!
- Wobbuffet: Time to leave, girls. This Pokémon is clearly a threat.
- Wobbuffet: Fortunately, we've got enough information. We'll carry out the doctor's mission somewhere else.
- Trio: Oki doki!
Deoxys
The final boss of Mt. Moon is Deoxys. This extraterrestrial mythical Pokémon appears to have animosity towards Jirachi, and values life little compared to the world's resources. Seeing you as an obstacle, Deoxys challenges you to a fight-it is surprised upon defeat, before warning the player that they will meet again. Deoxys has the moves Hyper Beam, Psycho Boost, and Giga Impact.
Boss drop:
- Exp. All
- Life Orb
- Tight Belt
- Stardust
- Comet Shard
- Deoxys' Heart Slate
Dialogue:
- ???: ... I SEE.
- ???: ... COMMENDABLE.
- ???: I SURELY COULD NEVER HAVE IMAGINED YOU BEING HERE...
- ???: YOU. YOU INCOMPETENT CREATURE.
- ???: YOU DARE SHOW YOUR FACE TO ME...
- ???: IT IS APPALLINGLY OBVIOUS, YOU SEEM TO HAVE SURPASSED ALL MY BARRIERS..
- Deoxys: YOUR PRIMITIVE RACE SOMETIMES LEAVES ME IN WONDER... BUT I VALUE NOT ANYTHING BUT THE RESOURCES OF THIS PLANET.
- Deoxys: THEN AGAIN, I WOULD NOT DOUBT THAT THAT CURSED WISH MAKER HELPED YOU...
- Deoxys: HOWEVER, LIKE ALL THOSE WHO DARE QUESTION THE LAW MAKERS OF THE COSMOS, YOU SHALL BE PUT TO REST.
- Deoxys: PREPARE YOURSELF, FOOLISH EARTHLING.
- Deoxys: GUAAARGHH...
- Deoxys: ... HOW?! THIS CANNOT BE POSSIBLE! MY CALCULATIONS, THEY CLEARLY STATED THAT...
- Deoxys: GUUUARFGH...! YOU HAVEN'T SEEN THE LAST OF ME, EARTHLING...
- Deoxys: WE ARE BOUND TO MEET AGAIN...

Dungeon Objective
Mt. Moon is a popular dungeon for many reasons. Deoxys has a chance of dropping rare and useful items; a Tight Belt, Exp. All, or its Heart Slate, which allows it to be summoned if the Heart Slate is combined with a 
Mystery Part. The exclusive recruitable Pokémon Kecleon, Purple Kecleon, and Beldum are found here. Blissey and Chansey can spawn, along with the Nidoran family spawning with the move Beat Up, making it easy to gain maximum experience every floor.
Rules
- You will need to have Rock Smash for the maze after Floor 10 if you haven't completed Mt. Moon.
Tips
- Many Pokémon here have the Ability Cute Charm and use Attract and immobilization moves. A Shed Shell, genderless Pokémon, or Oblivious Pokémon may prove useful.
- Bring a Mobile Scarf or a Ghost-type, and a Pokémon with Frisk. The items in the walls can be worth a good deal of Poké.
- Pokémon with Perish Song spawn on the later floors of both paths. It is recommended to bring a Pokémon with Safeguard or gems in the appropriate weather to gain immunity.
- If you are below Diamond Rank, if Deoxys drops a Tight Belt, you won't be able to pick it up. Be wary of this unless you're in a party with someone who is Diamond Rank or higher.
Trivia
- There used to be an item called Heart Pendant dropped by Deoxys, which boosted all team member's HP by 75. The item was removed as it was deemed too strong, especially for Pokémon such as Shedinja.
- Mt. Moon was closed on the 12th of March in 2019 for maintenance. It re-opened on the 19th and it was revamped significantly.
- The Clefairy and Clefable giving their prayers to the meteorite is most likely a reference to "Clefairy and the Moon Stone", the sixth episode of Pokémon anime's first season.
