Even though Springfield still spoke with a pronounced Australian accent in the mid-1970s, he provided his own voice for his animated doppelgänger. On the show, Springfield always wore white pants and a white sweater which sported on the front an encircled lowercase "r" with a lightning bolt in the background; this design was taken from the back cover of his 1973 album Comic Book Heroes. Springfield is joined by a cast of characters: "O Tut Tut, cat of ancient lore, Tis time to draw the magic door."
