Underground Jungle



The Underground Jungle is one of the more difficult areas in the world of Terraria. It is a dense network of small caverns, populated with thorns, water, and some of the more difficult enemies. You can safely but slowly make your way through if you have the Vilethorn, since you can wall yourself in at the first sign of Hornets and the kill them through the walls.

Shrines are common in this environment, often containing chests with rare items or weapons that can't be found anywhere else. Materials such as Stingers, Jungle Spores, and Vines (for use in crafting rare items) can also be gathered here in abundance. This biome will most likely end up taking you to The Underworld without much additional digging.

Hunting the Jungle
The Underground Jungle can be found directly under the Surface Jungle biome. Underground Jungle monsters and loot begin to appear in the middle of the Underground layer, at these depths:
