Folivoraphobia

Folivoraphobia is basically the fear of sloths. Although it may be a simple paranoia to those who don't have it and it may seem stupid, to those who do have it, it can vary from feeling like a strange small pest in the back of your mind to ... a life and death situation to be near one for certain reasons.
