Wimmin Is a Myskery (1940) is Popeye's 81st cartoon, produced by Fleischer Studios. It features Pipeye, Peepeye, Poopeye and Pupeye in their first appearance as Popeye and Olive's children in a dream sequence (and with slightly different names). Due to their popularity, they were soon adopted as regular characters in the form of Popeye's nephews. Margie Hines voices Olive, with Jack Mercer providing the voice of Popeye and all four boys.
