Rainforest biome

I want to turn the jungle biome into a rainforest made up of swamps, jungle trees, rivers, and lots of rainforest animals like poison frogs, frogs, snakes, crocodiles, monkeys, parrots, jaguars, and vampire bats. (Bats should bite if you hit them, and the bite should give temporary nausea and poison) (I would also like jungle villages)
