Do you know where the panda lives (... you most likely know)? Do you know where the babirusa lives (... you are less sure about that)? Some of us are not entirely sure what a babirusa is? In Fauna, you are not expected to know all the answers, simply gather your wits and make an educated guess. You are right on target? Great! You are close? That's good too, since you score partial points.
Playing Fauna involves some fun betting for points, but don't get cocky, as this may cost you your hide.
