The frog’s rear wheels and legs generate a slight jumping action and cause his big glum mouth to open and close as the toy is pushed along. Every rotation of the rear wheels makes a slight bobbing action. He is made from redwood. All components are sealed with varnish for durability and hygiene. The figure has a push handle at the back. This fun hopping toy was designed, made and decorated by hand as an individual and unique creation. Shipping costs will depend on your location.
