Switch 'em, swap 'em, shift 'em, race 'em! ModMobiles turn vehicular playtime into creative mix-and-match fun! Each ModMobile is made up of a real wood chassis with rubber wheels, two plastic runners, and three uniquely shaped foam body pieces, all of which can be switched out and mixed up. Already little gear-heads are reeling with the possibilities! With no snapping, clicking, or latching, each piece easily yet firmly slides into place in all kinds of ways. Go from a hot rod to a sedan to a tractor to a drag racer to a cruiser to a super car and beyond - All in just seconds! It's so easy! You'll never want to stop switching, flipping, mixing, and racing!
