"Djjin Djinn, the Pied Piper" is the third appearance of Jeannie's uniform hating puppy, each one less interesting than the one before. Dr. Bellows remembers the troublesome pooch, and is immediately attacked upon arrival. Gen. Schaeffer's Great Dane Jupiter is his pride and joy, but the often invisible Djinn Djinn wreaks havoc with his training in the park. Both dogs eventually end up at the pound, where the exasperated attendant (Dick Wilson) has been torn to shreds by the magical mutt. Gen. Schaeffer makes a go of finding his beloved Jupiter, only to get run over by a stampede of canines. The repetitious one joke idea behind this pup made for a series of weak episodes, though Dick Wilson's presence is reassuring, having already dealt with a poodle that used to be Major Healey in the second season's "What's New, Poodle Dog?"
