Still kept feeling like the face or ears need something (fluff in ears?) but anyway This little creature is actually a marsupial and not a monkey but the name stuck for me. It developed a barb on it's tail that it uses to stun (not kill) other creatures that live high up in the treetops alongside it. It is a night creature and the sting is painless. It wraps its tail around them to keep them from dropping out of the trees. It is of course carnivorous.
