TropiCraft and ZAWA combined
It's around 5 mods so it runs really well
The Zoo and Wild Animals mod spawn zoo animals and wild animals
Some new spawns- Elephant Okapi etc.
This gives you more animals to mess around with kill and even breed.
TropiCraft spawns Tropical trees and other stuff like that
There are Palm trees that spawn almost everywhere.
This gives you more wood to build houses out of and more builds like that.
