Make a frog puppet from a walnut shell half! Paint the shell green and add a red yarn mouth. A strip of red felt or paper would work just as well. Paint two circles green and add googly eyes. Glue to the back of the walnut as shown in the photograph. Glue a popsicle stick to the back. To make it easier to glue the stick to the back you can stuff the walnut shell with polyester batting and glue on a piece of felt backing the same size as the walnut shell.
