Mysterious Jungle (MJ) is a Grass and Bug themed dungeon first introduced in PMU 6 and was reintroduced in PMU 7. It can be found in Archford, southwest of Greenport Town. The boss of the dungeon is the Mythical 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 as low as level 50 up to level 100.

After Floor 20, there is a maze with a hidden pathway. There are a few visible spots through it with each having a hidden 
Mushroom. In the maze there are false pathways that might have an Explosion or Chestnut Trap or a hidden item. Overall there are 12 hidden Mushrooms and 2 hidden piles of 300 
Poké. Alternatively directly to the right of the beginning room is a shortcut taking the player to the end.
There is another puzzle after Floor 30. There are multiple bushes in every section; one of them is a switch that makes the shrub blocking the exit disappear for a limited time. Alternatively there is a shortcut on the left with shrubs removable via using the move Cut.
Instead of another puzzle, after Floor 40, there is a camp run by a Nuzleaf named Ka'giso. There's a Kangaskhan Storage rock, as well as a healing bed.

Dungeon Objective
Mysterious Jungle is one of the most popular dungeons for training, specifically for training Fire and Ice types. Valuable items spawn frequently and the boss, Mew, may rarely drop an exp boosting item—a Wonder Chest—or its Heart Slate. The Grass-type starters from Kanto, Johto and Hoenn can be obtained here. Mysterious Jungle is the dungeon where the sealed chamber for Grass Silk resides as well. Mysterious Jungle is also well known for the amount of supplies, making it a good dungeon for restocking.
Tips
- It is recommended that to bring a Pokémon with Safeguard, Refresh, Heal Bell, or Aromatherapy to deal with common status conditions like poison. However Safeguard will not help against Jumpluff since it has the Ability Infiltrator.
- Gems with the applicable weather condition are a good alternative at preventing status conditions as Infiltrator cannot bypass them.
- AoE moves such as Heat Wave and Blizzard are very powerful here. But be aware that it may not work with Parasect who has Wide Guard.
Trivia
Floor 40 rest point, before being revamped
- Mysterious Jungle was created by Kirk.
- All Pokémon that could be found in the original PMU 6 version can also be found in the PMU 7 version. The PMU 7 version also introduces some new Pokémon.
- Mew used to have a chance to drop a Miracle Chest instead of a Wonder Chest.
- Two Pokédolls and Dawn Stones appeared in the end room, but they were removed. A Pokédoll was later added back into the end room.
- Before, the rest stop after Floor 40 looked different, did not have a healing bed, and had an Escape Orb.
- Previously Bulbasaur and Aipom were egg-only. They were added as recruits in 2020.
