Amazon Rainforest is a module for the core game Nature that rewards bluffing, deduction, and perfectly timed reveals.

The Amazon Has Secrets!
Mysteries hide behind every leaf of the canopy - poisonous dart frogs, jaguars that can crack turtle shells, and monkeys in search of exotic fruit. This module adds a tropical watering hole, fruit tokens, poison resistance tokens, and 5 new traits, along with a major rule change: traits are no longer revealed at the end of the Adapting Phase. Instead, players may reveal a trait at any time to gain its benefit. Face-down traits provide no benefit.
