Living objects represent many of the more "alive" objects such as non-player characters and the like. They are much like changing things but have a few differences. The basic version (flipping living) flips left to right randomly. Living objects can also make sounds as the player passes in front of them. Currently, only certain animals produce a sound. To have an animal sound, add the animal name to the object name.
Changing living objects have two frames of animation like changing thing. The random frame change is slightly slower.
Moving living objects not only change between two frames but also move back and forth in a direction. This is good for walking (pacing) non-player characters.
