Once upon a time, Popeye had quadruplet nephews. In later years, they took one of the nephews out, leaving three.
"Pip-Eye, Pup-Eye, Poop-Eye, & Peep-Eye" made their debut in 1942. Here, then, is the colorized version:
It's almost as if Popeye himself had been cloned 4 times over in juvenile form, but the quads lack maturity, it would seem. Then again, kids weren't that into vegetables, not just spinach, back in those days. We would later see the boys take up music in what would be their best effort.
