A Masque Ball in the Boudoir

Baba has been thinking and when Baba thinks anything is likely to happen. She has been wary of all these artistic types who have descended upon her and has decided to test them a little. She is planning to have a Masque Ball in her Boudoir. Everyone is expected to come in full costume, make a grand entrance and amuse Baba with a short act. Is that a distant cackle I hear or that old rooster crowing joyfully?
