They first appeared in 1940 in Fleischer Studios's Wimmin is a Myskery ("Poopeye" is replaced by "Pepeye" in this episode), however their first appearance was only in a dream sequence as Popeye's children. Their first appearance proper as his nephews occurs in the 1942 Pip-eye, Pup-eye, Poop-eye an' Peep-eye. Their existence would indicate that Popeye's mother and/or his father had at least one child other than Popeye, however as they have only ever appeared within animated media as minor semi-recurring characters, their existence seems to be apocryphal in the overall Popeye continuity. They were only featured in two shorts of the Fleischer Studios era and were voiced by Jack Mercer whose voice had been sped up to sound like a child's.
