Better Jungle Mobs

It would be great to have more life in the jungles. we currently have things like pandas in the bamboo and tropical birds, but it would be cool to have things like monkeys or chimps, that could be trained or friendly if you feed them, or snakes that could poison you if they hit you, like cave spiders, but could drop potion/poison ingredients or like a poison sac that you could apply to arrows(like lingering potions) or a sword to deal more damage. also, there could be frogs, like tropical frogs, and more jungle trees and plants
