When Professor O. G. Whatashnozzle creates a machine that can send a chicken back into the egg, Brutus (Jackson Beck) decides to use it on Popeye (Jack Mercer) so he can have Olive (Mae Questel) all to himself. Here's "Childhood Daze", produced by Larry Harmon, and directed by Paul Fennell.
Kind of odd seeing Popeye (and later, Brutus) with adult faces on infant bodies. I guess the Professor has to go back to the drawing board.
As previously noted, Harmon employed some future talents from Filmation, including Hal Sutherland, Erv Kaplan, and musical director Gordon Zahler, who later worked as a music supervisor not just for Filmation, but also for Ivan Tors.
