Wimmy was a free House-Elf who gladly continued to serve the Prince family. She was born to their last House-elf, Mitzi Prince, and the Princes treat her as a member of the family, even giving her their last name and counting her as one of them. She has the family's permission to wield and carry a wand, choosing to use it only in self-defence. She wore a small maid's outfit with the Prince crest embroidered on the left breast and across the back.
