Animated adventures of an Irish piglet named Piggley Winks and his friends Dannan the Duck and Ferny the Bull, aimed at youngsters ages 4 to 7. The voice without a brogue belongs to Mel Brooks, whose role---he plays Wiley the Sheep---is to lead Piggley and pals astray. He comes up a loser every time. Incidentally, `Jakers!' is their all-purpose expression of amazement.
