Jungle



The Jungle is a surface biome composed primarily of grass, vines, Mud, Jungle Trees, and pools of water, with a dark green background. Jungle trees grow automatically on Jungle grass found there, though traditional Acorns can also be planted. The Underground Jungle is found just below the Jungle, beginning at cavern depths.

The Jungle is one of the more challenging surface biomes, especially for those just entering Hardmode. Jungle enemies have much more health and deal more damage than those typically found in other surface areas.

Players can seed new Jungle areas by planting Jungle Grass Seeds in Mud Blocks. Jungle grass spreads much more slowly than ordinary grass. A Jungle biome will activate once a minimum of 140 Mud Blocks are covered with Jungle grass, or with 140 Lihzahrd Bricks.

The Jungle becomes substantially harder during Hardmode. Additionally, there is a danger that the Jungle can be completely overtaken by the spread of Corruption/Crimson once Hardmode has been in effect for some time, making essential Jungle items more difficult to acquire, but defeating Plantera will slow down the spread of Corruption/Crimson and Hallow to 50% of their original speed in Hardmode.

Goblin Scouts can spawn here rarely, similarly to the forest.

Pre-Hardmode

 * Avoid knocking Beehives off the ceiling, as doing so will release Bees (and, on Expert mode, possibly a Hornet) that can easily disrupt your exploring.
 * It is recommended newer players have at least Silver/Tungsten armor when visiting the Jungle.
 * The Jungle will always be on the side of the map opposite the Dungeon and the Snow biome and on the same side as the Underground Desert. It is possible for it to spawn within view of the player's starting position, and very rarely, in the center of the map, giving some indication of the layout of the rest of the world.
 * To get some very good starter equipment without having to venture into the dangerous Underground Jungle to loot Ivy Chests, it may be worth it to fish at the Jungle at the very beginning of the game with a Reinforced Fishing Pole and Enchanted Nightcrawlers. Jungle Crates will drop the same loot as Ivy Chests but are easy to obtain as the Jungle often spawns with massive pools of water and it can be easy to avoid enemies by simply boxing yourself in. This way, you can obtain very powerful starter equipment such as the Anklet of the Wind and Boomstick without even having to defeat a boss.

Hardmode

 * All enemies in the Jungle (except for bees from fallen hives) have a chance of dropping a Jungle Key. (In the they drop the Jungle Key Mold). This will later be used to open the Jungle Biome Chest in the Dungeon after Plantera has been defeated, which contains a Piranha Gun, a unique ranged weapon which doesn't use ammunition and can be a useful side weapon. Consider farming for it before defeating Plantera, as all mobs are buffed (only in  Expert and  Master modes) after she has been defeated and it will be therefore far easier to farm them beforehand.
 * Consider building a house for the Witch Doctor in the Jungle in pre-Hardmode, as he will sell the Leaf Wings for only at Night at the beginning of Hardmode. Despite the complete lack of effort it takes to get them, they are the best wings on versions prior to 1.4.0.1 (alongside Frozen Wings) you can get until after defeating Plantera. On the, as of 1.4.0.1, they have been drastically nerfed and wing progression has been reshapen, but obtaining them may still be useful in the meantime until you obtain better wings.
 * It's generally recommended to completely avoid traversing the aboveground Jungle at the beginning of Hardmode. The enemies there don't provide much useful loot (with the exception of the Uzi, a very fast gun, and Turtle Shells, which are only relevant once the player has defeated the Mech bosses and can mine Chlorophyte) and the combination of their different attacks can kill the player in one or two hits, especially in Expert and  Master modes.
 * It is a good idea to section off the Jungle before activating Hardmode, or the Jungle might quickly be overtaken by the evil biome (Corruption/Crimson) and eventually be eliminated. The evil biome converts Mud Blocks within a three-tile radius of any corrupted block to dirt, and grows Corrupt/Crimson grass on it. This means that simply digging a three-block wide tunnel around all sides of the Jungle will prevent the evil biome from spreading to it. Since background walls cannot spread the evil biome (though they may get converted themselves), it is unnecessary to remove any walls that cross that three-block gap. However, thorny bushes may grow as bridges across the tunnel for the evil biome to spread across, a longer-term tunnel would need to be at least fifteen blocks wide, since thorny bushes can grow up to six blocks in both Jungles and evil biomes. To learn more, see biome spread.
 * However, it is very possible that, upon the defeat of the Wall of Flesh and activation of Hardmode, the 'V' shape created by the world evils including the Corruption/Crimson will breach the tunnel you've built to contain the evil. Therefore, your aboveground Jungle may likely still be infected even if you try to contain those biomes. To curb this, it may be a wise idea to instead spread the Hallow between your Jungle and Evil Biome by simply using Holy Water (which is easily craftable upon the start of Hardmode). The Hallow cannot spread to the Jungle and will also block the Corruption and Crimson, making it a worthy alternative to digging a tunnel.
 * The aboveground Jungle is generally far less important in terms of loot than the Underground Jungle, which will also be much harder for the Corruption/Crimson to fully infect. Therefore, your main priority in terms of the Jungle will likely be NPC housing, which is especially important on the where the Pylon network will make world travel far easier. It may be a wise idea to instead build your Jungle base deep underground instead of aboveground, as it is far less likely that it will be infected by the evil biome due to the sheer size of the Underground Jungle. It will also give you easier access to the Underground later in Hardmode, such as when setting up your Plantera arena.
