This unique wind-up toy is designed to look like a Mars Rover, and features a dual-color scheme with one color on top and one on the underside. However, this is no straight-forward wind-up; in fact, it rarely ever moves straight at all! Due to an ingenious lever, the runner will periodically flip over to its other side, changing direction in the process. Just wind it up and watch it flip out! Makes a great stocking stuffer for the intrepid explorer in your family!
Note: Although we do try and accommodate specific requests for the color of wind up toy received, we cannot guarantee which one will be shipped to customers. Picture shows two wind-ups for demonstration purposes only--price is per each unit.
