Underground Jungle

The Underground Jungle is a very remote area of the world, residing deep Underground. However, it is possible for a jungle to be generated on the surface post-1.0.4. Like Dungeons, these areas have few dead ends; unlike Dungeons, however, they are covered in plants. They have special items that are found in Jungle Shrines, small buildings made of Gold Bricks that are spawned at random locations in the below layer in the Underground Jungle.

It is possible for the jungle to fuse with the Corruption or the Crimson. It is also possible for the surface jungle to fuse with the Desert. A Glowing Mushroom biome can be inside of an underground jungle since both of them use Mud blocks.

Features
The Underground Jungle is a biome found mainly underground (see the name). It usually makes its home from about 5% to 10% of the entire underground (might vary by map size). Much like dungeons, they stretch across the top of their horizontal location to the bottom of the map, stopping a bit above the Underworld biome. Other monsters common in the overworld and in the dirt-rock and rock-dirt layers can be found, but it has four unique monsters: the Hornet family, which consists of the Hornet itself, the Little Stinger and the Big Stinger, and the Man Eater, which are the only current way to get the Stinger and Vine respectively. The world generator also places more Gemstones in Underground Jungles.

Underground Jungles are located on the opposite side of the map from the Dungeon, and digging at the halfway point between the original spawn and the ocean will often place you into the Underground Jungle. They are also often found under or next to the Corruption or the Crimson. Underground jungles are always located under above ground Jungle biomes. The buffer between the Underground and the Underground Jungle is spottable by a random mixture of mud and stone/dirt.

Jungle Shrines
Jungle Shrines are small gold buildings found in the Underground Jungle. They are similar to the Floating Island's shrine but smaller. Each shrine has a chance of containing a Chest that contains special equipment and items not found in other Environments. Shrines may contain zero or two Chests, but this is very unlikely. They also sometimes appear very close to the surface when your Jungle Mud is above ground during rare occasions.

Items that can be found in the Jungle Shrine chests include:
 * Dynamite
 * Feral Claws
 * Staff of Regrowth
 * Anklet of the Wind
 * Dragon Mask (Console Only)
 * Bottles, Lesser Healing Potions and Gold Coins also appear frequently.

Rarely, Jungle Shrines can be found floating above an underground jungle. However, this may only happen when an underground jungle extends to the surface.

Hive
The Hive is a structure found deep in the Underground Jungle. It is surrounded by Hive blocks, which can create Honey or Bees when destroyed. Inside can contain Honey, which provides life regeneration once walked in, or collected. Occasionally there is Larva, which summons the Queen Bee once destroyed.

Lihzahrd Temple
The Lihzahrd Temple is a large structure found deep in the Underground Jungle. It requires a Temple Key to enter, which is dropped by Plantera. Inside the temple are dangerous monsters, including Flying Snakes and Lihzahrds. The several rooms has Pots, unique (and upgraded versions of) Traps, and Lihzahrd Chests. Inside is a Shrine, which is a large room which has a large Golem Spawner, which requires a Lihzahrd Power Cell to use.

Finding the Jungle
On a small map you can usually find the jungle at about 600-1300 feet below.

On a medium map, you can usually find jungle at 800-2200 feet. It is common to find lava in the deeper parts of the jungle

It is occasionally possible to see the top of an Underground Jungle at the surface of your level, amongst the Forest Biome.

As of update 1.0.4, underground jungles are now directly underneath surface jungles.

There are also rare occasions in which you may find 2 Underground Jungles in one world.

(see picture at right).

Use a Depth Meter to see how deep you are.

Plants and Items
Underground Jungles also contain several unique plants, such as the Jungle Rose, Nature's Gift and jungle spores. The Jungle Spores are used in tier 2 to 3 crafting, necessary in weapons such as the Thorn Chakrum and Blade of Grass as well as the tool Ivy Whip; furthermore, Jungle spores, Vines, and Stingers from Hornets are needed to craft the Jungle Armor set. If you can, try to make an area to craft while in the Jungle and make yourself the Thorn Chakrum and Ivy Whip asap (if you don't already have them or higher tier items) as these are both extremely useful for fighting the monsters safely and navigating the Jungle more easily.

The Underground Jungle can also be helpful for making Obsidian if there is a Lava pool because of the fact that there are many water deposits.

Underground Jungles are made almost entirely of mud, and this can sometimes reach to the surface leaving large areas of almost entirely mud, which can be used to locate the Underground Jungle. Another way to help locate the underground jungle is to dig down to about 700-1200 depth and go horizontally. As of 1.1, the underground jungle may also have Silt Blocks, which look similar to ash but behave like a gray sand which cannot be crafted into glass.

The jungle grass spreads faster if it has a two block high or wide path to grow on.

Leaving the hanging grass uncut can be limiting because it severely hampers your view of the surrounding area.

In the underground jungle using any weapon with which you would cut normal grass can be used to cut grass in the jungle making it have the same properties as well as being able to drop Jungle Grass Seeds however they can only be grown on mud for more info see Jungle Grass Seeds.
