This miniature walking penguin toy is a classic child's toy. You can use the instructions to make a penguin as shown, or change the color scheme and make other flapping walking toys, a duck, a goose, or a blue footed booby. The toy doesn't take a lot of special materials to make. It is a good project for beginning woodworkers, as it uses fine hand files and a fine drill rather than specialized tools.
If you prefer, the toy can be made using card with a pin for an axle, but it will not be as sturdy if anyone wants to see it in motion.
