In this episode, an accident in the lab creates a clone of Dennis!
When Dennis loses one of his brand new football boots – the ones he earned by promising to do extra chores - he asks Professor von Screwtop for help. The Prof offers to clone a mirror image of the remaining footy boot in his quantum duplicator.
But when Dennis grabs the boots before they duplicator is finished, the machine starts to clone him too! Out pops a boy who looks like Dennis, but who is actually the exact opposite - a kid who loves to behave and follow rules, and even speaks backwards!
Dennis thinks it's great because while the clone sits in class, Dennis gets to stay out and play. Walter soon finds out, and tries to convince Dennis's clone to break into the lab and create an army of clawed clone cats!
