Mysterious Jungle, also known at MJ, is a Grass/Bug themed dungeon first introduced in PMU 6 and was reintroduced in PMU 7. It can be found in Archford, South-West of Archford Town. The boss of the dungeon is the legendary Pokémon Mew.

Due to the amount of resources provided, ease of defeating enemy Pokémon and experience points gained, Mysterious Jungle is one of the best late-game dungeons to train Pokémon from level 50 up to level 100.

Several exclusive Pokémon can recruited here in the Mysterious Jungle.


Every 10 floors starting after the 20th floor, there will be maze-like floors - one has an invisible path, another has switches, and yet another has no obstacle besides running all the way to the end of the floor.

MJ Undergrowth

Mew can be found at the end of this dungeon at Level 80.[citation needed]

Defeating Mew will spawn a warp that takes you to a room with two Deluxe Boxes, two Pokédolls, and a Dawn Stone.

Upon defeat, Mew can drop Big Mushrooms, or a small chance for a Miracle Chest, though there's also a chance of Mew not dropping anything. However, Mew also has a chance of dropping a Heart Slate, which allows Mew to be used by the player in a dungeon once Mew's Heart Slate is fused with the Mystery Part.

Before fighting:

  • Hello!
  • I've watching you... teehee.
  • You seem like a fun Pokémon to play with!
  • I don't have to ask, because I'm Mew!
  • Lets go! teehee!

After defeating:

  • Owwwwwie!
  • That hurt! I wanted to play, not fight!
  • What!? are you telling me I played too rough with you?
  • That's just nonsense!
  • You're such a big meanie!
  • Waaaaahhhhh!

There are 5 switches in total: 4 outside switches and 1 inside the chamber with the boxes so the player can get out again. The one that correctly opens the path is the top left button.

  • It is recommended that you bring a Pokémon with Safeguard or Refresh to protect against all of the status moves here, like Poison Powder. However safeguard wouldn't help against Jumpluff since it has infiltrator.

  • All Pokémon that could be found in the original PMU6 version can also be found in the PMU7 version. The PMU7 version also introduces some new Pokémon.
