Suggestion of how they could do it:
This feature would be great for stories containing pets or stories about shape shifters. This should be available for all animation styles with a couple templates of cats and dogs. The editable features could be:
Fur color and style
Eye color and shape
Some basic actions could be: sleep_stretched, sleep_curled, curled_awake, stretched_awake, stretch, yawn, walk, trot, run, idle, idle_sit, idle_lay, hiss(cat), bark(dog), bite, bite_receive, smack, smack_receive, attack, attack _receive, meow(cat) growl(dog), idle_angry, jump, eat, and an action for being carried that works when a human character does the hold baby action and the characters are places correctly. The outfit options could be different collars or more if Episode chooses to make more. Cat and dog bed and food bowl overlays could be added along with more animal sounds like cat meow, cat his, dog whine and dog growl. They already have dog bark and cat screech.
Since these would be characters, and Limelight is what Episode is currently working on, I would be okay if the animals were Limelight style.
