You're a small mammal! You're shy. Or maybe not. Who knows? One thing is for certain: You're definitely a mystery to those around you. You neither put your thoughts forward nor make your feelings known. Still, people tend to like you even though they can't figure you out. If you do make yourself known to people, chances are they think you're smart and quite coy. You have a soothing effect on those around you, although some people may find your reserved demeanor disturbing. You like being alone best, although people don't bother you, since you're good at tuning out distractions.

I don't know who invented this, but a Kangaroo is not a small mammal. Trust me on this. And they seem to think koalas are a social member of the ursine group. They aren't, and they're not bears either.
