In the French version, the latest treasure from Uncle Georges is a device which is supposed to detect deliveries and release an alarm when it does so. Doc wants to use it to get the mail, which makes Croquette jealous. The machine only succeeds in attracting such items as balls, shoes, and a broom, and Croquette has to bark when the postman does arrive. Meanwhile, Uncle Traveling Matt observes a group of men patiently fishing for shoes.
