This movie is very funny and extremly witty. It is about a 13-year-old named Will who has failing grades. To get a good grade in science, he purchases a ocean pet kit from Ocean Pets Inc. At the ocean pet labs, two of the workers discover how to "hyper-clone", and to test it, they clone a mouse. One of the workers leaves the cage door slightly open when they leave. The clone mouse notices, and pushs it open. A cat nearby pops out of it's cage and scares the mouse. The mouse tips over the beaker with the clone formula in it and it drips into the kit that Will gets. When he gets it, he pours the ocean pet liquid in and then can't find the stir stick. So he takes his comb and stirs with that(it has some hair on it). Since the clone liquid is in that, it creates a clone of himself. The clone is smarter than Will, and goes to school instead of Will. Meanwhile, the workers try to track down Will to get the clone....
