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. 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.
Flipping Living objects have one cell which is horizontally mirrored in random time intervals.
Changing Living objects have two cells, similar to Changing Things, which are changed in random, slightly slower time intervals.
Moving Living objects not only change between two cells but also move back and forth in a direction. This is good for walking (pacing) NPCs.
