This fun little wind-up toy looks just like a stout fire engine, but unlike a real engine, this little guy is extra safe; it'll never fall off of the surface on which it drives! Every time the wind-up truck hits an edge, it will change its course to avoid falling off. Just wind it up and watch it go, without fear of falling! Makes a great stocking stuffer for the aspring fire fighter in your family, or as a small prize for contests of any sort, or for party favors at a children's birthday party.
