There's nothing wrong with a little cheating on a test, right? WRONG!
And so begins another McDoogle disaster as one little lie leads to a bigger lie that leads to a humongously, out-of-control lie! When the chaos reaches its peak, the entire world thinks it's under attack by a space alien- that has a striking resemblance to a giant porcupine. Wally, the giant porcupine space alien, is pursued by tanks, helicopters, even a guided missile or two - not to mention his old friends at SOS (Save Our Slugs) who are now, oddly enough, trying to save him! In this hair-raising (er, make that quill-raising) misadventure, our boy blunder learns that honesty really is the best policy.
