Jungle

The jungle is a rare lush biome. Jungles typically generate near warm biomes, such as deserts and savannas. It has a total of seven variants.

Description
Jungles are mostly heavily forested, rivaling the Dark Forests in tree density. Unlike the short and thick trees of the dark forest, however, jungle trees can grow very high, and are the tallest trees in the game, with the tallest of them being well over 30 blocks in height. Oak trees may also grow within the tall jungle trees, and "bushes" made of oak/jungle leaves and a single log grow on the floor of the jungle, which frequently obstruct view of the bright green grass below. Many of the leaves and logs of both types are covered in vines. Jungles contain varying terrain, from the typical dense foliage of the main Jungle biomes to the grassy meadows that form in Jungle Edge biomes.

Cocoa pods and melons generate on jungle logs and in patches on the ground, respectively. Melon patches generate somewhat more often than pumpkin patches do in other biomes. Single shoots of bamboo may generate in the jungle as well. Additionally, the parrot, ocelot and panda mobs exclusively spawn in jungle biomes, and chickens spawn at higher rates compared to other biomes. Occasionally, a jungle pyramid may generate within the foliage; as they are partially made of mossy cobblestone and also covered in vines, they can prove hard to spot from a distance due to the density of the trees. Jungle terrain is mildly hilly, not unlike the Forest biomes, but is exacerbated by the bushes that generate on the floor. Additionally, jungles may generate unique, shallow lakes that are much larger than the typical small ponds found in other biomes, just like forests do.

Survival in jungles can prove to be very difficult. While running out of wood likely won't ever be a problem, obtaining said wood can, due to the heights that jungle trees can grow to. Additionally, jungle trees are significantly less sustainable compared to other trees, as their leaves only drop saplings 2.5% of the time, compared to 5% for all other trees; this means large jungle trees often only drop enough saplings to regrow them and not plant any new trees, while small jungle trees may not even drop a single sapling. The dense foliage can easily get a player lost without some sort of trail marker, such as torches, and clearing the foliage for shelter is no easy task, due to both the heights it can reach and the sheer amount of it. However, ocelots and parrots can make for useful pets when tamed; ocelots can repel creepers, while parrots can alert players of nearby hostile mobs. Cocoa beans and melons can also be farmed for dye, food, trading, and other such purposes.

While not specifically related to survival, jungle biomes are notorious for being significantly more resource-demanding to load and render compared to other biomes, particularly Jungle Hills and Modified Jungle variants. Thus, players exploring in jungles may wish to turn down their graphics settings to avoid lag and FPS drops, especially on weaker computers.

Fishing
In jungles, only cod and salmon may be caught during fishing. Bamboo can also be collected as junk in category.

Variants
There are seven jungle biome variants; making jungles the largest biome family in the game.

Jungle
The standard biome variant in the jungle family, Jungle biomes feature the distinctive large jungle trees and dense foliage across the ground. Jungle pyramids can generate in this biome, and Ocelots and Parrots spawn here (as they do in all jungle biomes).

Jungle Hills
Similar to the Wooded Hills biome, the Jungle Hills biome features steeper terrain, making it a more difficult variant of the already difficult jungle for survival purposes. Ocelots, Parrots, and jungle pyramids may all still generate here.

Modified Jungle
The rare Modified Jungle variant features much more mountainous terrain, being taller and steeper than jungle hills. The heights, combined with the thick foliage, renders the ground below almost entirely out of sight. This is among one of the most difficult biomes for survival, as the tall mountains being combined with very high tree density renders the landscape almost entirely unsuitable for shelter. Ocelots and Parrots may spawn in this biome, but jungle pyramids do not generate here.

Jungle Edge
The Jungle Edge biome is a technical biome, intended to be a smooth transition from other biomes to the main jungle. Trees still generate here, though at significantly lower rates than the main jungle, roughly comparable to the rate of trees in the Savanna biome. The grass still takes on a very bright green color, though slightly less vibrant than the main jungle. Jungle edges do not entirely border a jungle, however; they may be replaced by rivers or beaches, omitted entirely when jungles border forests or taigas (though not their variants), or widened when jungles border swamps. Ocelots and Parrots may spawn in this biome, but jungle pyramids do not generate here.

Modified Jungle Edge
The extremely rare Modified Jungle Edge variant only generates in strict conditions, and is the rarest biome in the game, covering only a few millionths of the Overworld by area (the very rare Mushroom Fields biome covers about a thousandth, for comparison). In order for modified jungle edges to generate, a Swamp Hills biome must generate right outside the edge of the jungle. This results in a double-layered transition, with a thin normal Jungle Edge bordering the swamp hills, and the modified jungle edge bordering the jungle. As both jungles and swamp hills are already rare, and even more rarely do they generate bordering each other, the conditions for a modified jungle edge to generate are extremely rarely met. When they actually do manage to generate, they are often only a few hundred blocks in length, making them one of the smallest biomes as well. Modified jungle edges feature the same smooth transition and lowered tree density that regular jungle edges have, though with more mountainous terrain and occasional overhangs. Ocelots and Parrots may spawn in this biome, but jungle pyramids do not generate here.

Upcoming variants
The following variants are upcoming in Java Edition 1.14 and Bedrock Edition 1.9.

Bamboo Jungle
The Bamboo Jungle variant generates in large patches within regular jungles. Trees are much less dense in this variant than in the main jungle, comparable to the Jungle Edge, but boasts countless amounts of bamboo across its landscape. Swaths of grass blocks are replaced with podzol, similarly to giant tree taigas. Additionally, all naturally-generated trees are large variants; only 2x2 jungle trees and large, branching oak trees may generate, though many of the oaks are simply small "balloon" oaks. Trees planted and grown by the player can be any size. All jungle-exclusive mobs, including pandas, may spawn here, though jungle pyramids do not generate here.

Bamboo Jungle Hills
The Bamboo Jungle Hills variant is similar to the bamboo jungle, though with steeper terrain just like the regular Jungle Hills variant. Large amounts of bamboo cover the landscape, and patches of podzol replace grass blocks. Naturally-generated trees are always large variants, like in the bamboo jungle. Oddly, jungle pyramids may generate in this variant, despite not generating in the base bamboo jungle; additionally, pandas do not spawn here, while all other jungle-exclusive mobs can.
