Structures

General Information
Structures will generally spawn in any Jungle biome. The so far planned structures are abandoned huts, a pyramid-like jungle temple, an another pyramid-like temple but with stairs, and few other things such as springs.

Jungle Hut
These are planned to be in Update 2.0 and the future. These will spawn rarely in the jungle and will have basic loot. they maybe part of a Jungle Village structure, maybe

Jungle Village(Needs to be confirmed)
Most tribal villages or normal jungle villages have a really high chance of a wild banana tree spawning in them and an occasional chance of having an intermediate/domesticated.

Jungle Village
Villages that spawn in Jungles (such as some sort of new village type)

Normal villages will have a rare chance of having intermediate and an even rarer chance of finding a domesticated tree in the Plains Village.
