Jungle (old)

This page describes variants of jungle biome that have been removed in Java Edition 1.18 and become unused in Bedrock Edition 1.18.0:

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 pandas spawn here and jungle pyramids may still generate here.

$$, jungle hills use the same mob spawning chances as jungles for ambient categories. As for the others:

$$, jungle hills use the same mob spawning chances as jungles.

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. Ocelots, parrots, and pandas may spawn in this biome, but jungle pyramids do not generate here, modified jungle biomes are similar to the jungle hills, but can sometimes have differences.

$$, modified jungles use the same mob spawning chances as jungle hills for hostile and ambient categories. As for the others:

$$, modified jungles use the same mob spawning chances as jungles.

Modified jungle edge
The rare modified jungle edge variant generates only in strict conditions, and is currently the rarest biome in the game. If a jungle biome borders a swamp hills biome, then the modified jungle edge spawns as part of 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 rarely met. When they actually do manage to generate, they are often just a few hundred blocks in length, but in some cases are less than 10 blocks, 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 much more mountainous terrain and occasional overhangs. Ocelots, parrots, and pandas may spawn in this biome, but jungle pyramids do not generate here. Modified jungle edges cover only a few millionths (0.00027%) of the overworld by area. For comparison, the rare mushroom fields biome covers about 0.056%.

Modified jungle edges use the same mob spawning chances as jungle edges.

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 most grass blocks. Naturally-generated trees are always large variants, pandas may spawn here, like in the bamboo jungle. Jungle pyramids may also spawn here $$.

$$, bamboo jungle hills use the same mob spawning chances as jungle hills for hostile and ambient categories. As for the others:

$$, bamboo jungle hills use the same mob spawning chances as bamboo jungles.
