Molly is one of the races known as "-0 tails" they don't grow tails. there metropolitan characters that live primarily in the major city's of there world. Molly lets Justin and Tiy stay in her apartment for the night since they don't have anywhere else to go and she thinks they are there to see the Rock Awna concert just like her. Molly is pretty much Polly if she was a cat girl. many times I often wounder why I made there ears so pointy since the only cats who have pointed ears anywhere resembling that are bobcats. but they obviously aren't all bobcats... I guess it was just esthetically pleasing to me when I first drew them. like a sorta elf meets cat kinda ears. many people often say they look pickachu-like but I don't see it...
