KingTrapinch's Jungle Worldgen
This Minecraft mod transforms your world into a lush, overgrown jungle.
It works by re-organizing the biomes in worldgen to feature mostly warm, swampy, and tropical biomes. It also inserts biomes from the Twilight Forest mod to add tall canopy trees, hissing cicadas, and towering structures.

This mod works great for modpacks to create jungle-themed scenarios like:
- Jurrasic Dinosaur World
- Stranded Jungle Survival
- Bug-Infested / Parasite World
- Florida (for some reason...)
- and more!
Requires the following mods to work:
- The Twilight Forest (CurseForge)
- Feature Recycler
The following biomes have been swapped in worldgen:
Temperate
- plains > swamp
- forest > sparse jungle
- birch jungle > jungle
- old growth birch jungle > bamboo jungle
- river, beach > mangrove swamp
- swamp > cherry grove
Note: Dark Forest and Old Growth Spruce Forest swap places in worldgen (O.G. Pine removed)
Hot
- jungle (sparse, bamboo) > twilight swamp
- wooded badlands > fire swamp (twilight)
- badlands > wooded badlands
