In this short scene, we learn that a fishmonger named "Vivet" has earned a bonus by selling fish to a customer named "Shrimp Man." The fishmonger tells us that the customer is afraid that eating the fish will cause him to lose his eyesight. He tells the customer that the fish contains a chemical called "sulfur phosphatase" that can cause a cat to lose its sight in one eye or both. The fish also contains "unsaturated fatty acids," which can cause inflammation in the eyes and skin of cats. The customer is horrified by the contents of the fish, and he and the fish hatch a plan to capture the fishmonger and his accomplices.
