Fang, Mrs. Grumbler loves to eat Siberian fleas.
Mr. Grumbler says they are very expensive on Omega 6, but he always buys her a few for her birthday. If Fifi and Mrs. Grundy want to get rid of their fleas I think the Grumblers can help. Maybe Mrs. Grundy should invite them for tea.
P.S. I don't think the Director can use the holograms in the chorus. Have you noticed? They have no sense of rhythm.
