Framing Device: The first short, "Wolf Hounded", has a bandaged Loopy recalling his story of what happened before the events of the short, where he rescues Little Red Riding Hood's basket from the Three Little Pigs, only to wind up with injuries.Fractured Fairy Tale: Loopy found himself caught up into these plenty.For example: in one short, a pair of rocket scientists can't use dogs as test subjects because of the Humane Society's objections, but they're delighted to see Loopy because "nobody cares what happens to a wolf.".
Given this series began in 1959, it's not too hard to understand what it's supposed to be an allegory for.
