At first glance, the Munny looks like a miniature replica of an oddly shaped concept car at an auto show, only in dire need of a paint job. That's where your creatively inclined grandchildren step in. The bulbous car, plastic driver and surprise accessories included in each set are also blank canvases on which they can decorate with paint, crayons or any media they fancy. Once the Munny (pronounced "money") is properly souped up, your grandkids can race it around its paper track, which is also blank and ready for their artistic genius. Some "Vrrooooom!" noises required.
