When an odd twist of events brings a parrot to the ranch, Hank and Drover are not worried. What harm can one mimicking bird do? Hank goes about his business and does whatever Sally May and Loper ask him to. The only problem is, they don't appreciate his heeding their requests to bark louder or dig up the flowers. What's really going on? Hank's not sure, but he's determined to get to the bottom of it!
