Pearl I want a little mouse like Pearl. One who helps you with your jewelry and such. The lovely lady in the portrait keeps a hunk of sharp cheddar cheese on a chain around her neck as a motivational tool for Pearl. It's an added benefit for Pearl, but she does it mostly because she's such a sweetheart and needs to keep busy to calm her nerves.
Pearl also does Madame's hair. She's still trying to convince Madame to let her build a little nest up there.
