Synopsis by Hal Erickson
Popeye prepares dinner for his lookalike nephews Pip-eye, Pup-eye, Poop-eye and Peep-eye. The kids get through the soup all right, but when Popeye serves up four plates of spinach, his nephews try to sneak out and go fishing. In a strenuous effort to convince the boys to eat their spinach, Popeye demonstrates how the leafy green vegetable has helped "Powderewski" become a brilliant pianist, "Fred Upstairs" to become a world-class dancer, and "Jack Jumpsey" to be a champion prizefighter. Alas, the kids are unimpressed, forcing Popeye to punish them. Inevitably, the kids down their spinach, whereupon they set about to teach Popeye a few lessons of their own. This is the last "Popeye" cartoon in which the leading man appears in his traditional costume: thereafter, he'd been seen almost exclusively in Navy Whites.
