Well, since Koalas sleep 18 - 20 hours each day, this tends to be the "Traditional Koala Pose" most people get to see....

They're not bears, they're marsupials from Australia. They have a pouch for their joey (their baby). There the joey stays for about 6 months. At seven months the joey is slowly weaned off milk to eucalyptus leaves, which is their food. I've learned from the Science Channel that they don't drink water, but I don't know that for sure....
