This story is a sequel to A Little Girls Love
What if Mavis wasn't a Mermaid and/or Gorgon? What if she was a werewolf? A Witch? A Vampire? An AU to A Little Girl's Love.
This story contains a lot of cute moments, including Mavis being a bit of a klutz, her wearing hats that are a few sizes too large, etc.
Chapters won't be terribly long. They'll just go over how each type of Creature Mavis is would fit in with the human children, and the ponies.
