At nine o'clock The Cat Club will convene to celebrate this wondrous Halloween night in Jenny's Moonlight Adventure. All the cats, from twins Romulus and Remus through to the wise Solomon, have been looking forward to this evening. The high point of the party is to be the nose flute performance by the Persian cat Madame Butterfly, but she has hurt herself, cannot leave her house, and has lost her instrument. The flute is found in a pile of autumn leaves but there's still the problem of how to return the flute to its beautiful Persian owner. Jenny comes up with a very adventurous plan. After all, Halloween is "her" night. But will she pull it off?
